The Caves of Rock Spring
Rock Spring
district, in a hydrological and speleological sense, is a very large catchment
located in the southeast corner of the Cockpit Country. It collects rains from
about 25 sq km of terrain, and feeds it to the northwest, where it eventually
disappears in the junction of the yellow and white limestone that is exposed at
Rock Spring. Between these two points is a section of alluvium that is used
extensively for farming, and through the length of the valley flows the Mouth
River.
The map shown
below, (Fig RS-1), is based on a Digital Elevation Model for Jamaica, and
clearly shows the catchment areas for both the caves of Rock Spring,
(northwest), and Quashies/Bristol, (northeast). The primary direction of flow
is indicated, but water is also collected from the hills on either side. For
the Quashies/Bristol system, it will be seen that the central area where the
caves are located is lower than, and surrounded by, hills on all sides. For the
caves of Rock Spring, it is not as obvious on the DEM map that the waters
collected must find their way underground to exit the catchment, but this is
also the case. A map that shows the geology of the district, (Fig RS-2), in
particular the area of exposed yellow limestone, will help to make things more
clear, and this will be found below the DEM.

Fig. RS-2
On the map above,
the area that has been left transparent to show the topo map beneath is
primarily yellow limestone at the surface. The inlier, and the white limestone,
have been coloured yellow and grey, respectively. The pocket of alluvial soils
is pink. The flow down the catchment is indicated. It can be seen that when the
local run-off, including that of the Mouth River, gets to the lowest point, in
the northwest, it runs smack into the white limestone. This is at a point where
cockpit karst begins, and the terrain to the northwest is solid hills and
valleys. The average height of the land slowly decreases in a continuing line
into the Cockpit Country, but the hills that are met by the river at Mouth Maze
rise up high enough to block the flow, and force it to follow the junction of
the yellow and white limestone through bedding planes underground. In places
downstream, it pops out again, (at least the upper part of it does, because
there is believed to be an entirely subsurface flow under this, via Mouth
Sink), to flow on the surface through cockpit bottoms where erosion has opened
pockets back down to the junction, but before too long the cockpits no longer
extend down to the yellow limestone, and the entire flow remains underground
until it reaches the northern edge of the Cockpit Country.
At Rock Spring, a
complex network of river caves has formed because of the concurrence of a large
catchment, and the junction of the yellow and white limestone at the downstream
end. Separate from the river caves are several other sites that are high and
dry, (e.g. Carambie), but the majority of the sites in the district are very
wet labyrinths that have multiple entrances.
The rest of these
introductory notes will address the river caves, specifically, how to find
them, and what to expect. When one is first confronted with the many entrances,
and many passages, involved in the system, it can be very confusing determining
what is what. We will attempt to bring clarity to the situation by presenting
below a guide to finding, and conducting research in, the caves of Rock Spring,
but we do so with a warning - there are parts of the system in which it is very
easy to get lost, and very easy to drown. Please do not use the information
presented below to get yourself killed, and if you do, don't blame us.
We will refer to
the map, RS-5, that accompanies these notes often in the course of the
following discussion. The positions are GPS derived, and were obtained by the
JCO during the PiP Project. The accuracy, (listed in the notes for the
particular caves), is such that they will enable all of the entrances to be
easily found.
First, it must be
noted that some of the upstream entrances, (sinks), have been degraded by
siltation, and access is not guaranteed. Because of this, listed entrances can
appear to be nothing more than muddy sinks. This is the case for Farmyard Cave,
which is the first site at the upstream end of the system. In the past,
entrances to a stream-passage could be followed upstream to a sump, and
downstream to a rocky section where the water continued underground to Printed
Circuit. The entrances to Farmyard Cave are currently mud-choked. They are an
entry point for water that runs off of well-cultivated land in a catchment
above. One cannot now enter the cave, other than to slide on your belly through
mud for about 20 metres, (the drainage is now greater on the surface, to sink
at Flux U, and water backs-up above the entrances to Farmyard in the
rainy-season).
The main flow
into the Rock Spring system is the sink of the Mouth River, but it is not
restricted to this. Additional input occurs to the east at Printed Circuit,
Pool Cave, and Swanga Cave, as well as at cockpits located to the west of the
Mouth River sink. Of these secondary sources, Printed Circuit is the greatest.
The last of the downstream surface activity, and caving access, is found at Too
Far Glade, the third of three cockpits past Mouth Maze, where the system hits
the surface for the final time. In between these two ends is a whole heap of
passages, and we'll try to explain things as best we can. An area plan of the
passages, produced by the work of the KHE, (Fig. RS-3), will be found further
down, and we suggest that this be referred to while reading the following
description of the overall system.
Mouth River, and
the cave it sinks into, Mouth Maze, are the core of the system. There are two
entrances for the river, the year-round Sink, and the rainy-season flood
entrance which is the Main Entrance to Mouth Maze. The Sink sumps after a short
distance, and access to the system is from the Main Entrance, (shown on the
RS-5 map as Mouth Maze - Sink). Inside the cave, a network of rectilinear,
joint developed passages ultimately feeds the bulk of the flow to the
north-northwest to rise at Good Hope Glade, (shown on the RS-5 map as Mouth
Maze - Good Hope Sump). This cockpit floods during rainy times, but a seasonal
streambed will be found during dry times. On the other side of the cockpit, at
the end of the seasonal streambed that rises at Good Hope Glade, the water
sinks again into Good Hope One Cave. This sink was a choked mud-pit in
April/May 2005, perhaps due to the effects of Hurricane Ivan, the autumn
before. On the other side of a saddle, in the next cockpit, the river rises
again. This is the north entrance/rising of Good Hope One Cave. From here,
another seasonal streambed meanders across the cockpit to sink on the north
side at Good Hope Two Cave. Again, by passing through a saddle, one will find
the river rising once more at the north entrance/rising of Good Hope Two Cave.
Another seasonal streambed meanders across the glade, until it sinks at Far
Enough Cave. This sink, the entrance to Far Enough, was mud-choked during our
visit in May, 2005. One last cave is found in this downstream end of the
system, and this is Too Far Stream Cave. It is not part of the direct
river-course, but rather seems to be a tributary that apparently links with the
river underground, to the northwest of Far Enough. The immediate source of Too
Far is a rising spring, (very pleasant to look at), on the south side of the
cockpit in which it is found, (this cockpit is quite spectacular and will be
described in the notes for Too Far). From Far Enough and Too Far onward, there
are no more surface break-outs known, but one must suspect that there is
potential un-tapped by the KHE due to the distance into the bush, and the amount
of hiking involved.
To the west of
the Mouth River, at Rock Spring, there are the two Harties caves, entered via a
collapse in a saddle in a hill above the present day water-course. Harties
Cave-2 in the past probably acted as part of the original water-course, or as
an overflow during flooding - the development was certainly stream-based, and
fossil meanders can be seen not far into the cave. Harties Cave-1 is somewhat
higher, with the passages on the same level as the upper part of Cave-2, but is
also stream-developed. Because these two caves were originally one, until the
collapse split them, one can suspect that like Cave-2, there are also passages
on a lower level in Cave-1, not currently accessible.
Immediately to the east of the Mouth River is
found the best known cave in the district, usually referred to as the eponymous
Rock Spring Cave, but more correctly called Printed Circuit in order to clarify
which of the many caves in Rock Spring is being talked about. Like Mouth Maze,
it is a labyrinth of stream-passages, but at Printed Circuit the system is more
consistent in its hydrological activity. Water over a metre deep flows
year-round through the main collector, fed by an array of sinks on the upstream
side, and possibly also subterranean flow from sinks further to the south. The
outflow joins the waters of the Mouth River to carry on to Good Hope Glade.
Further yet to
the east of the Mouth River are two smaller stream-passage caves, Pool and
Swanga, that parallel the Mouth system. They both sink, rise, and sink again
with the suspected next rising at Greater Swanga, a site not listed in JU. We
must take a minute now to address the confusion in the name for Swanga Cave.
The people of the district know Swanga as Banga Cave. We are positive that we
had the right site for the target, Swanga, that is listed in JU, because of
scaling from the area plan found below, and the map of the interior of the cave
matching what we found. The confusion arises because there is indeed a site
called Swanga by the local people. It is an enormous shallow shelter cave, with
a rising at the bottom, that is found north of Pool and Swanga-Banga, in a
cockpit. It is in the direction of flow for both Swanga-Banga, and Pool, and we
suspect it to be associated with them. We surmise that the KHE, when asking of
existing names for the caves, heard Swanga and Banga, did not quite catch the
"Banga" because it was said in Patois, became confused, and assigned
the name Swanga to the wrong cave. In this report we will refer to the two
sites as Greater Swanga, the giant shelter cave, and Swanga-Banga, the listed
stream-passage cave. Curiously, Greater Swanga was not listed by the KHE,
perhaps because there is no actual cave that can be entered, just an
impenetrable rising.
It would be
suspected that the waters of Pool and Swanga-Banga, after rising again in the
Greater Swanga cockpit, eventually somewhere join the general flow that has
passed through Mouth Maze, but this is undetermined. We did not have time to
pursue this, because of priority on finding the listed caves, and a
corresponding lack of time to work on new sites.
One more stream
cave, Iron Maiden, is found even further east. This cave seems to be not
directly connected to the system - the water that sinks here heads off to the
northeast to rise in a cockpit south of the JU position for Burnt Hill Caves.
Before we
conclude these introductory notes, we should discuss an observation made during
the expedition regarding the rising of the Mouth River system, believed to be
at Fontabelle. I will quote below an excerpt from our entry for Fontabelle
Rising:
"In 1965-66, the Karst
Hydrology Expedition used lycopodium spore tracing to determine that the source
of the rising was at Mouth River, in Rock Spring. From March 29 to April 3,
2005, our team had been carrying out work in the caves of Rock Spring,
including Mouth Maze. In fact, we had visited about ten of the caves in the
district during this period, and were very familiar with the internal
hydrological conditions. We were on the tail-end of an extended drought, with
bush-fires common in the district, and the caves of Rock Spring were as dry as
they usually ever get. This had been fortunate for us, because there was no
flood-risk to deal with.
On the morning of April 3,
when we departed Rock Spring, it was still dry. In the afternoon, while we were
exploring the undescended pit at Barbecue Bottom Hole-2, north of Rock Spring,
some light showers fell in the area but there was no sign of storms in the
direction of Rock Spring. When we arrived at Coxheath that evening, we were
told that Bottom Pond, associated with Fontabelle rising, and the rising
itself, had both been high for a couple of days, and the road to Friendship was
flooded at Bottom Pond. This is a regular occurrence in rainy-season.
We found it quite surprising
that Fontabelle was high, because we knew for a fact that there had been no
rain in Rock Spring for over a month, other than the showers that day which
were after the time when Fontabelle reached its high-point. We are left with a
question: where did the water come from? It certainly wasn't Rock Spring.
The team with the KHE who
conducted the initial tracing were experts in their field, and one must accept
their determination at face value, but we cannot help think that there must
then be a second source, perhaps to the west of Rock Spring. Near Heading,
there are sources such as Wilson's Run Cave that might be considered, but this
is speculation.
The morning of
April 4, in Windsor, we observed that the Martha Brae River, below Windsor
Cave, was still low, and clear. There was no activity at the Flood Rising
resurgence. We can therefore readily accept that the source of the Windsor
resurgence could be Rock Spring, because the dry conditions at the SE end would
have been reflected in the low waters at Windsor. Whatever the other source
might be for Fontabelle, it is not associated with the Windsor Cave
resurgence."
There is no doubt
in our minds that there is something not quite right in the currently believed
flow from Rock Spring to Fontabelle. We, of course, have no problem accepting
that the Windsor resurgence has its source at Rock Spring, because we have seen
no evidence to suggest otherwise, but that connection is not established. By
looking at the DEM, it seems the input for Windsor could be from Booth, (see
Fig, RS-4, following the Rock Spring area plan). There is essentially a long
valley that extends from east of Bamboo Bottom, (i.e. Bad Hole), most of the
way to Booth. This is conjecture on our part, but clearly, the hydrology of the
Cockpit Country is not entirely understood, and could use more work.

The map that accompanies
this section, (Fig. RS-5), indicates the positions for the known caves in the
Rock Spring district that were visited by the JCO as a part of the Parks in
Peril Project. The positions are GPS referenced, and have an accuracy as given
in the notes below, and the database that accompanies this report.
The tracks shown as dashed
black lines on RS-5 indicate the best routes that we found to Good Hope One,
Good Hope Two, Far Enough, and Too Far. The eastern of these is the best way in
and out of the Far Enough and Too Far glades. The track will be easily located
if you bring a copy of the map, look carefully, and use a compass en route.
A complete list of the known
caves and sinkholes of Rock Spring follows. Those indicated in bold were
included in the PiP Project, and detailed notes will be found for them in this
chapter. The others in the list, targets excluded from the PiP Project, have
also been included in the chapter, but with information limited, in most cases,
to what is known via Jamaica Underground, and notes consisting mostly of a
brief explanation of the reason for their exclusion, and our best advice for
finding them. Positions for the excluded caves are given only in JAD69 Metric
Grid coordinates, as received from JU, because the accuracy is undetermined and
positions derived from transformations to other datums could prove to be
misleading.
Caves marked with ** are JCO
discoveries/explorations and are not found in Jamaica Underground or databases
derived solely from it.
Information for
the caves included in the project is in the following format: first, a table
that presents a number, but not all, of the main parameters of the assessment;
second, a field report on how the assessment was conducted. All of the data
collected will be found in the digital database that accompanies this report,

Comments: This was on the
list of caves that we hoped to do, but was a low priority for two reasons: It
will be difficult to find, because it is in a district with few residents,
and is listed to be over a kilometre into the bush. The cave is reported to
be small, and to consist of only 25 metres of 3m wide passage. Time did not
allow us to search for the cave, and it has been put on the JCO to-do list. |

Carambie Cave is
in the Rock Spring district of south Trelawny, and was visited by the JCO as a
part of the Parks in Peril Project. It is one of the few caves in the district
that is not a river cave, and is instead high and relatively dry. The cave is
easily found, with two entrances on a hillside that faces the Spring Garden to
Burnt Hill road.
This morning, we
started the day with the full team of four assembled, and drove in Ivor's car
from Miss Buckle's, where we were renting rooms, to the general area where the
cave was indicated to be in Jamaica Underground. Because the cave is locally
well-known, it was soon found, visible from the road, and we were parked and
ready to go. Although the most obvious entrance is only about 30m from the
roadside, it is also about 20m above the road, and the hill that one must ascend
to reach it is rather difficult, since there is nothing to grab onto other than
a barbed-wire fence. The slope is of dirt, bare of vegetation on the straight
track that leads up, and a slip would result in a rapid slide down that would
deposit one back on the road after a final drop of about 2m, (to then possibly
be crushed by a passing car). Needless to say, we were all careful on this
dodgy little approach.
There are three
entrances to the cave; two facing the road, and one around back on the far side
of the hill. The most obvious roadside entrance, to the north, is about 5m high
and 3m wide, facing east, and leads into a large chamber known as the
"Light Cave", that is entirely in the twilight zone. At the back of
this is a small opening into a larger chamber, this opening situated about 6m
above the floor of the second chamber. Although it could be climbed down if one
were desperate to do so, vertical gear is advisable. About 50m south of the
first entrance, a second entrance is found, smaller than the first, and this
leads into the so-called "Dark Cave". Access from this entrance to
the rest of the cave is possible without the use of vertical gear, although a
bit of a scramble is necessary to reach the chamber that is seen from the back
of the "Light Cave".
We had taken a
quick look in the first part of the cave, inside the first entrance, before
finding the second entrance and going in by this route. I soon found the
scramble into the rest of the cave, then went around to the far side of the
large chamber seen from the opening to the Light Cave, and located the back
entrance. This third entrance faces 265 deg, and requires a bit of a scramble,
found not far into the cave. A GPS position was taken, and then I rejoined the
others. Ivor deemed the site to have been attractive to Taino in past ages, and
so while he and the others looked for any evidence of this, I looked for
critters.
Much of this
cave, estimated at 50%, is twilight zone. In the central chamber a small
bat-roost is found, with numbers estimated at under 500, and the main species
fruit-bats. There are no substantial guano deposits, but some extraction has
taken place by local people anyway. The material extracted appears to have been
old, compact deposits, along with the underlying mud. Used bottle torches are
present, and fertilizer bags. Surprisingly, I didn't see any Periplaneta
americana, (roaches). Observed invertebrate predators were one species of
spider, and Neoditomyia farri, (predaceous fly larvae). Fungal gnats were
present. The numbers of Cave Crickets, U. cavicola, were rather low, but
this might have been a seasonal variation since we in the late stages of a
drought. Historically, two Coleoptera, (beetles), Leiodinae and Catopinae, from
this cave were studied by Dr Stewart Peck.
The bat-roost has
seen enough disturbance that only a fraction of the roosting space is being
used, although it's expected due to the large percentage of twilight zone that
it would be preferred by fruit-bats, and they seem to come and go periodically.
The spider xx that was collected should prove to be the most interesting
critter observed, and identification is underway.
The cave is
formed in the yellow-white limestone junction. Stals, flowstone, and small
helictites are found, with the latter located in small nooks at the sides of
the chambers where humidity is higher. It should be noted that although much of
the cave is dry, there is a section that was quite damp, especially for the
dry-season that we were in, with most of the water entering through percolation
from above.
No evidence of
Taino usage was seen, and having done what we needed to do, we left the cave,
made our way carefully down the hill to the car, and moved on to our next
target.
We're listing this cave with a medium vulnerability because of the
bat-roost found here, and the trog Araneae and Coleoptera. There has been a history of guano
extraction, now infrequent because the main deposits are gone. There is no
immediate threat, but it should be recognized that the site is of interest.
Notes: DK Roggy
The light cave
entrance can be seen from the roadside, at the top of a steep hill and lying
under a small escarpment. The hillside had been set alight recently and thus
the ground was bare. We found the footing to be difficult as we made our way up
the dry, clumpy soil up the 30 to 40 degree slope. From the light cave chamber
one goes straight back and comes to a wall with an opening into a larger
chamber, what I would call the dark cave.. Through the opening is a steep and
slippery slope. Since Jamaica Underground told us that the dark cave entrance
would be an easier way to go through, we went back out, traversed along the
edge of the escarpment and came to the dark cave entrance.
From the dark cave entrance we went into the large dark chamber that we
could see from the light cave. The light of the morning sun showed through the
light cave entrance, then through the hole at the end of the light cave chamber
and into this one. Where the light struck within the dark cave I found
historical graffiti. As far back as 1821 people had written their names and the
year, apparently with coal, and in a rather elegant fashion. This led me to
wonder whether we might find Taino petroglyphs or pictographs in the same area,
as it seemed an obvious place to do so. With the assistance of Ivor and
Elizabeth we looked around, but found no such evidence of Taino occupation.

This is a short passage that is flooded in much of it. We could not get into
to it to look, but it is likely that stygobites are present, crabs, Sesarma
spp, as they are found in most of the other stream passages in the district,
and the name Crayfish suggests that shrimp were observed here by the KHE. |

Team: Stewart, Roggy
Notes: RS Stewart
This site was
found by Stewart and Roggy just before we located Pool Cave. We had been
traversing cross-ways to the streambed that we knew to exist between the two, to
use this to locate both targets, and we happened to first hit it at the
downstream end, the sink of Crayfish Cave.
A currently muddy
pit, (pulse event from Hurricane Ivan appears to have silted in a number of the
sinks in the district), takes water from the end of a short stream that rises
at the north entrance of Pool Cave. Although the KHE managed to get in here a
few metres, and then dive a short sump to reach several more metres of passage
with air-space, we were not able to penetrate this sink at all when we found it
due to mud, (although it allowed water to flow through it in several holes).
The land immediately around the sink is overgrown scrub pasture, and has poor
cover. We found Pool Cave to be fairly silt-free, for reasons described in
those notes, so it does not seem to be the main source of the mud. Most of what
is entering Crayfish Cave comes from the land on either side of the streambed
downstream of the Pool Cave rising.
The name of this
cave is interesting, because "Crayfish" is Jamaican for
river-shrimps. Apparently either the KHE found them here, or the people of the
district had seen them in the pool at the entrance sink. We looked for shrimps
during our time in the river caves of Rock Spring, but didn't see any. Part of
the problem was that other than Mouth Maze, we were usually in stream-passages
that had no dry floor - we were constantly wading/swimming and stirring up
sediment, so there was no chance of seeing them. We had no choice in this,
because there were so many caves to cover in the relatively short time that
funding allowed - we could not spend hours standing around in any one cave.
This was recognized in our planning for the proposal, and we had thusly limited
our activities to gathering as much information as quickly as we could, with a
foucs on indicators such as bats, guano, roaches, N. farri, siltation,
etc, and positions that would enable researchers to easily find sites that
might be of interest to them, as suggested by the indicators.
From Crayfish Cave, we followed the streambed upstream to find it
rising from an entrance to a passage that resembled what we should expect for
Pool Cave. After wading through this passage to the south, and finding it to
match the KHE map, along with the entrance at the south end where we came out,
we were sure that we had both Crayfish and Pool Caves. In the course of it, GPS
georeferencing was done for the three entrances, and it will be a lot easier
for others to find these sites in the future than it was for Dietrich and I,
(much tramping around in the bush with a machete).

Notes: RS Stewart
Far Enough Cave
is the final downstream cave associated with the Mouth River known at this
time. The cave was found by the KHE to trend east, and finally end in a sump
after 380 metres. If there is a rising for Far Enough Cave beyond the sump,
further into the Cockpit Country, neither the KHE, the JCC, or the JCO know
about it. This does not mean it isn't there, but if it is, it remains to be
found. Our own explorations in the district have only extended as far as those
of the KHE, so essentially, no one has gone to take a look. But, by plotting
the KHE cave map on the topos, using our GPS position for the entrance, we can
make a guess where a rising might be found - 18 19 03.0 N, 77 34 13.5 W.
It took us two
tries to find this site, first at the end of March, and then successfully on
May 13, with the rainy-season underway. Apart from the flood-risk that might
have been a factor, because of thick mud at the fissures that drop into the
start of the passage, we were locked out and were able to do nothing but get a
good position, and learn the lay of the land. This was at least of value,
because as a result of our search we can supply GPS points for the best route
to the glade, and coordinates that will allow the entrance to be quickly found.
On May 13 the
entrance to Far Enough was heavily silted, exactly the same as the other sinks
upstream in the system, (Good Hope Cave One, Good Hope Cave Two, several
upstream entrances to Printed Circuit). The cockpit in which it is located
showed obvious signs of having experienced great flooding, presumably during
Hurricane Ivan. For all three of these entrances, even though water was carving
holes through the mud to drain into them, for a human to get in would have
required much shovelling of unstable mud.
We are not
entirely sure which of several sinks in an area about 50 metres across was the
entrance, because all were muddy. The position listed is for the most likely
sink, but it could in reality be one of the others. The land is open around the
GPS position, so it will not take long to find and have a look at all of them.
We saw heavy
siltation throughout the entire Mouth Maze to Far Enough system, and it is
obvious where it comes from. The land in much of the catchment immediately
above is heavily cultivated alluvial soil, with no ground-cover between the
banana, yams, coffee, or whatever. The farmers are diligent in their labours,
and the soil on their farms is cultivated, loose, and ready to move when heavy
rains arrive, such as with Ivan. Along with this topsoil there is an incredible
amount of garbage that is washing into/through the system. At Mouth Maze, it
was astounding - we'll go into it further in the notes for that cave. Beyond
the downstream exits of Mouth Maze, at Good Hope Glade, the entire streambed to
the sink of Good Hope Cave One was littered with bottles, and scandal bags, and
you name it, all washed through from the Mouth River sink. This garbage
actually extends right through the entire system, travelling through, Good Hope
One Cave, along a stream and then through Good Hope Two Cave, and still found
in the streambed that leads to the entrance to Far Enough Cave. It is no doubt
continuing onwards into Far Enough, and what is happening to it there is
anybody's guess, because this is the end of the known surface part of the
system.
Access to the
glade where this cave is located is via two routes, and has been addressed in
the intoductory notes to this chapter.
We are listing this site with a medium vulnerability, because of the
potential for clogging of the passage downstream due to the garbage that washes
into the cave, and the siltation caused by local agriculture.

Team: Stewart, Roggy
Notes: RS Stewart
We started out
the day by splitting the team into two groups, with the plan being that we
would again join forces at noon and move on to the Good Hope Glade caves. The
morning would be spent in this way: Dietrich and I would resume our search for
Farmyard Cave; Ivor, Elizabeth, and Minke Newman would tackle Harties Cave-2.
Minke, an intern with The Nature Conservancy - Jamaica, had joined us first
thing in the morning, and would be with us for only one day. As things would
have it, her time with us would be spent in a couple of the more challenging
caves that we were to visit in Rock Spring.
For D and I, much
of the morning would be spent above-ground, searching for Farmyard Cave which
was somewhere not far to the south of one of the entrances to Printed Circuit.
We had looked for it already, on Mar 30, when hunting down entrances to Printed
Circuit, but had had no luck. Now, we were armed with more knowledge, having
accumulated enough GPS positions for enough entrances to allow us to sort
things out, and be relatively sure of which entrance to Printed Circuit that
Farmyard Cave would be found near. This would be wpt 183.
Not long past
9:00 AM, we were at entrance 183, and we then began a thorough hunt for our target.
We spread out, and began to look carefully at every single possibility, these
being hollows, and the upstream ends of seasonal streambeds. Working our way
back and forth in the area, an hour passed with no success. It was mystifying;
we knew that somewhere within a circle of 150m south of wpt 183, we should find
several small entrances facing east that led into a stream-passage, but there
was nothing to be found. Finally, when Dietrich and I in our ramblings were
fairly close together again, in desperation I decided to look in a very small
depression that lay right under the track that we'd been using to access
entrance 183. The track ran through farmland, well-cultivated, and one would
think that any entrances would be glaringly obvious. After moving down into the
1.5m deep hollow that lay at one point beside the track, and hacking at the
weeds with a machete, things suddenly came clear. Before me in the weeds was a
very small opening about 75cm high, rising from the dirt. Calling out to
Dietrich that I might have it, I took off my pack, turned on my headlamp, and
squeezed my head and shoulders in.
To the left, a
low passage ended in mud about 5m away. To the right, the passage carried on
past the entrance, also low and muddy, but continuing if one were to slither on
one's belly. D had now caught up, so I slithered in to see what could be found.
After about 20m, I saw signs of another small mud-choked entrance, and now
realizing that things were beginning to match the KHE map, (although with one
great difference), I worked my way back to where I'd come in, searching for
what should be a continuing passage leading upstream, that is to the left of
the entrance that I'd come in by. It had looked mud-choked, but it needed a
closer examination. I spent 5 minutes looking for any chance of getting past
the choke, and found nothing. I crawled back out of the "cave" to
have a closer look at the printed scan of the cave map.
The map, seen
below, shows the passage that leads upstream, or at least once did, because it
does no longer. It also shows three entrances, of which only two remain. Lest
any who read these notes suspect that I had found the wrong cave, note that the
two entrances that we found match the map perfectly in location and aspect. It
is immediately upstream of Thicket Entrance, Printed Circuit Cave. There was
nothing else in the vicinity that could be found. We had the right cave, but
unfortunately it is now so full of mud and silt that it is essentially
filled-in. I am unsure which of the three entrances I entered by, but suspect
it is what remains of the "South Entrance", (wpt xx). At any rate, we
could only find two entrances, so the third apparently is filled-in.
I will quote the
KHE notes from Jamaica Underground: "The southern continuation of Printed
Circuit Cave where flux passage reaches the surface at Thicket Entrance,
(wpt 183). A meandering passage continues to the Main Entrance beyond which
are two ducks over rimstone pools and a crawl to a sump. Right leads to a sump.
Left, a low wet passage for 25m to a T-junction, choked on the left and sumped
on the right."
As can be seen,
this passage was never terribly high to begin with, and because of the heavy
cultivation of the land upstream, (the sumps noted by the KHE were merely low
parts of the passage, and are being fed by upstream sinks with locations
undetermined), and at the entrances, (which take water seasonally), it is now
basically gone. We noted several other cave entrances during our days in Rock
Spring, most notably Good Hope One Cave - Sink, that suffered from the same
problem, no doubt exacerbated by Hurricane Ivan, but Farmyard Cave was the most
extreme example. The district is heavily farmed, especially in the south
catchment area, by very hard-working farmers who constantly keep the land
tilled with no vegetative cover other than their coffee plants and yams, that
is, with roughly 95% of the dirt loose and easily washed away in heavy rains.
In fact, a farmer who was of much help earlier in the week showed us a sink
that was currently blocked, (barely seen, but he knew where it was from when it
had been open), that he noted needed to be cleared to allow water to drain from
his field. What is one to do? The farmers are hard-working, and doing the best
they can to maximize what profit is available, but in the course of this
industrious cultivation they are doing great damage to the river-caves that are
found here. I will merely describe the situation for now, but in the notes for
Pool Cave, which was quite silt-free thanks to an acre or two of bush cover at
the sink entrance that was holding silt, I will make what recommendations I
can.
One can speculate
that if vegetative cover were to return to the catchment area, eventually the
mud in the cave might be washed out and the cave would return, but
realistically this has a low probability of happening at any time in the
foreseeable future. For now, there are no biological observations for us to
note, because there was virtually no cave for us to access. Perhaps upstream,
something remains, but it is not possible to get to it without many weeks with
a shovel, tunnelling up the passage.
After getting a very good GPS position, we headed to Miss Buckle's to
link with the rest of the crew.
We're listing this site with a high vulnerability, because of the
problems with siltation, but there is little cave left to protect at this
point.
Farmyard Cave
April 1, 2005
Notes: DK Roggy
Stefan and myself went
around the area in which we suspected the cave might be. We asked some locals
if they knew of a cave nearby, and were pointed in down a dirt road and off to
the side of it. When we got to where we'd been directed we found ourselves at
the double entrances of Printed circuit that face each other. This was the same
place that we popped up out of the ground on March 30, to the bewilderment of a
couple young children.
We assessed where we were
and looked around. We came across a farmer and asked him where Farmyard cave
might be. He directed us through a field and down a hill. When we got there we
found ourselves at the entrance to Printed circuit that we'd been shown on
March 29. This was the entrance that we went into before emerging at the double
entrance described above. We wondered whether Farmyard cave even existed
anymore. It had to be somewhere nearby. Stefan headed just south of the
entrance we were at, along a path off to the side of yam cultivation. At one
point the path turned off to the left and there was a bit of tall grass in the
curve. Stefan stepped down into the grass, chopped a bit with his machete and
found an entrance. It was almost covered with rocks and mud. Stefan went inside
and stated that it was almost totally choked up with silt. The cultivation in
the area had nearly filled in this cave.
I backtracked up the path and cut down some tall
stiff grass to find another entrance. It was very much choked up and would have
required moving rocks and digging to even stick my head inside. It seems
evident that the last 40 years of cultivation since the KHE has affected this
cave tremendously.

Team: Stewart, Conolley, Roggy, Slack, Gary
Notes: RS Stewart
Good Hope Cave
was our third cave of the day, (not counting a large unlisted shelter cave
found in the morning), after Carambie, and Swanga. It was shown to us by Gary,
a friendly man who lived close-by, and at the time we did not realize that it
was one of our targets. In the Rock Spring district, there are two other caves
named Good Hope, those being Good Hope One Cave, and Good Hope Two Cave. When
compiling information prior to the expedition, I had neglected to add this one
to the list, it becoming lost in the confusion of names. I should note that
earlier in the expedition, near Maroon Town, we had investigated a cave called
Hope River Glade, and I hope to not have to visit another cave with the word
"Hope" in the name for at least several months - it's becoming rather
difficult for me to keep them all straight.
Good Hope Cave is
found not far from Carambie, and is at a similar elevation, and also
morphologically similar. Like Carambie, it appears to be formed in the
yellow-white limestone junction. It is primarily composed of one large
breakdown chamber that has been divided into two sections by a remarkable wall
of formations, (described in more detail below). It has one known entrance,
large, found high on the side of a hill, that faces west. Gary was familiar
with the cave, and told us that in the past he had found another chamber,
(other than what is obvious when making a cursory exploration), that had
beautiful formations, and that he had only been into this once. The reason, it
transpired, that he was being so helpful today, (assisting us in finding Big
Swanga, and Swanga Banga), was that he wanted us to assist him in re-finding this
new, beautiful chamber, since during his only other visit he had had nothing
but a bottle torch for light, and could not spend as much time in it as he
would have liked. We, of course, were happy to do this, and upon making the
short hike up the hill from the Good Hope Glade road, to reach the entrance,
under the impression that we were visiting an unlisted, new cave, we were glad
we had done so. We were obviously at something that had some potential, and was
of some interest.
The cave is
entered by passing through gaps on either side of an enormous boulder that sits
just inside of the entrance. This giant chunk of rock is very impressive. It
has broken off of the ceiling, to sit on the floor below, and in this sense is
nothing out of the ordinary - but it is massive. Although not measured, it is
over 15m across, and 12m high. On the top, it generally matches the shape of
the ceiling from which it fell, with a space of about 2m left above, but on all
sides, including the top, it is smooth, and rounded, as though it has been
eroded by water over a long period. The cave is currently high and dry, so this
seems to indicate that the giant boulder has been sitting in place for many
thousands of years, since a time when the surrounding land was higher and there
was indeed a flow through the cave that at least occasionally rose to the roof.
Although it might seem odd that I was so fascinated by this giant rock, it
should be understood that when one looked at it, one was very aware of the vast
amount of time that nature had invested in this cave, and also the great
changes that had happened to the exterior landform in the passage of those many
millennia.
Interior of the
great rock, a chamber about 25m wide, and 15 high, extends into the hill.
Towards the back, about 60m inwards, there is a pile of breakdown boulders that
extends from floor to roof, and wall to wall. Through this, gaps give access to
further parts of the chamber, until at no great distance the end is found. Near
the back of the main chamber, outside of the boulders on the south side, there
is a lighthole. On the south side of the main chamber, several openings lead
into what at first appears to be a second chamber, that runs beside the first
one. Inside this next chamber, the formations are marvellous. Flowstone, and
fluted columns, make up most of the walls, and there is little left of the
native rock to be seen. Elizabeth in particular found this very beautiful, this
being the most well-decorated cave she had seen to date. The two of us had gone
into this section first, while the others searched for Gary's lost chamber,
(which was to remain lost, because we never did find it), and we carefully
scouted around to see if there were any other continuations to be found.
Nothing was seen, other than gaps down into voids under the boulders, and after
about 20 minutes of this we returned to join the others.
Once back in the
main chamber, and looking around, I now realized that the whole cave was in
fact one very wide room, with the dividing wall being composed of nothing but
formations, floor to ceiling, essentially a long series of pillars, grown
together, with just a few gaps left in it. Again, the morphology of this cave
is fascinating. The width of the cave is much more than what you would usually
find, because the horizontal extent is such that it should have collapsed by
now. Apparently, the crack that extends above the formation-wall, that allowed
the speleothems to form, created a load-bearing wall that has enabled the cave
to survive all these years. This beautiful underground realm is much more than
a simple hole in the ground - it's like a living creature, structurally
improving itself as the years have gone by.
Biologically, the
cave serves as an occasional roost for fruit-bats, (much of the main chamber
being twilight zone), and there are no substantial guano deposits. Trog inverts
weren't seen, (we might have missed seeing some that were indeed present), just
terrestrial opportunistic critters and a few Cave Crickets, but because of the
lack of invasive roaches and relative low-levels of nutrients, there may be
potential for interesting troglobites if one were to spend enough time looking
for them. There are no stygobites, because there is no water to speak of, other
than what drips through cracks in the ceiling.
Dr Fincham, in
Jamaica Underground, notes that this site was mined for guano by the Jamaican
Agricultural Association in 1938-42. It is interesting to note that in 2005
there are no accumulations of guano that have built back up over the last 60 years.
As noted, the bat-roost is small, and appears to mostly consist of Artibeus
fruit-bats due to the relative lack of dark-zone. Artibeus do not use
particular caves as consistently as some of the other species, and are
therefore not in residence all the time. It was, no doubt, many centuries of
guano that were removed by the JAA, and it will take many centuries for it to
come back.
Also in JU, the
length is given as 15 metres, but it is much more than this, and although we
didn't survey the cave, we have stated it at over 70 which is our best guess.
We devoted
another 30 minutes to searching for Gary's lost chamber, with no success, as he
grew increasingly frustrated. He has a recollection of having found a squeeze
down through rocks to find a particularly well-decorated room, but despite our
looking through every little gap that we could, we did not find what he sought.
Perhaps it is truly there, and we just didn't get lucky. Perhaps he was in the
chamber that Elizabeth and I had explored, and had managed to find a different
way in, under rocks from the main chamber, and thought he was somewhere else.
We will leave this mystery to others to solve.
A GPS position
was obtained, (wpt 197), with some difficulty, due to the cliff in which the
entrance is found; I am listing the position with reduced accuracy to reflect
this. The coordinates given will certainly allow the cave to be found, but they
could be much improved. Nevertheless, plotting the GPS position on the topos
afterwards seemed to show the entrance right where it should be compared to the
local topography.
We are listing this cave with a low vulnerability, because much of the
damage that could be done, (i.e. removing the guano), has already occurred.
Good Hope Cave
March 31, 2005
Notes: DK Roggy
This was a cave
that our local friend Gary wanted to show us. What we saw in this cave was a
large breakdown chamber, the entrance of which was obstructed by a boulder
about 60 feet wide and 30 feet tall. This boulder had fallen from the roof ages
ago and been shaped around the bottom by flowing water. After going past the
boulder we came into a large chamber. On the right side of the chamber was a
hole through which some of the others passed, and found some interesting stuff.
At the far end of the chamber was a series of break-down boulders that
we crawled around in search of the passage and chambers that Gary had
described. Gary may have confused this cave with some other, because he
described a passage where one enters a chamber with 4 passages, go into one and
come into a chamber with another 4 passages off of it, etc.

Good Hope One
Cave is the first of several stream passage caves found downstream of Mouth
Maze. There are two entrances: the Sink is located at the end of a seasonal
riverbed that starts at the Good Hope Glade Sump Entrance of Mouth Maze; and
the Rising is on the other side of a saddle, in a different cockpit. Access
notes for both entrances will be found in the introductory notes for this
chapter.
We located the
sink to the cave first, on April 1, with the help of a local man named Calvin
who showed us a track from the east side of the Mouth River sink, over a saddle
to Good Hope Glade. The following day, April 2, we would return to the glade
and find the downstream rising of Good Hope One Cave.
April 1, 2005
Team: Stewart, Conolley, Roggy, Slack, Newman
The hike over the
saddle from the Mouth River was not bad - a little steep, but not long. Just
before the glade, we hit a main trail and learned from Calvin that this started
at the end of the Good Hope Road. We were already familiar with it, having seen
it the day before with Gary, who had told us it went to Good Hope glade. We now
had both ends sorted out.
As soon as we
were down into Good Hope Glade, we intersected a deep seasonal streambed that
meandered from our left, (southwest), north through the cockpit bottom.
Following this, we soon reached a series of several muddy pits that were acting
as sinks. The last of these seemed to be the one that would contain the
entrance to the stream passage, but it was much too mud-choked to enter. It was
now late in the afternoon, (we had already done Harties Cave-2, and Farmyard
earlier in the day). We didn't want to push any further into the bush in search
of the rising, in case we got caught out after dark on the hike out, so we
reversed back along the streambed to see what we could find at the rising end
of it. We weren't exactly sure which cave we had yet, and checking the upstream
source would help to narrow things down..
At the top-end of
the riverbed, we found an entrance to a passage that held deep water, and a
small flow trickling out. We decided to follow it in. At points, we were up to
our necks, half-wading, half-swimming, with the ceiling of the passage only 20
cm above us. Minke Newman, an intern for TNC-J, was with us for the day. Prior
to this outing, she had never been in a non-tourist cave before. She had
already dealt with Harties Cave-2 fine, (not exactly an easy cave), and would
show herself to be brave indeed for this next little jaunt. She didn't whine,
complain, just stoically followed along, as we moved through sections where the
ceiling was so low you had to turn your head sideways to keep your chin out of
the water. After about 100 metres of this, we hit a sump and could go no
further, so we turned and made our way back out.
Once we'd had a
chance to plot GPS positions afterwards, we could compare things to points that
we'd already gotten, especially the main entrance to Mouth Maze, and could
determine that the muddy sinks were Good Hope Cave One, and the long sumped
passage at the top of the riverbed was one of two entrances to Mouth Maze at
Good Hope Glade. The one we were in is the one that is shown with a sump in the
KHE map for Mouth Maze.
The Mouth Maze
passage held S. verleyi, and N. farri. This will be included in the notes for
Mouth Maze, along with the position.
We now began the
hike out, and although I was in favour of going back over the saddle to the end
of the Mouth River, the others preferred to hike out along the trail to the
Good Hope road. This was fine, as we were able to become familiar with the
track, but it did mean a fair hike on the road to get back around to Miss
Buckle's.
April 2, 2005
Team: Stewart, Conolley, Roggy, Slack
We hiked to Good
Hope Glade via the track from the Good Hope Road, after parking near the end of
it. After reaching the sink of Good Hope One Cave, we crossed through the
saddle beyond the sink, to hit the cockpit where we expected the passage to be
rising. Once through, we soon found it low on the east side, as soon as the
saddle is left behind. An entrance a few metres high, and less wide, is found
past boulders and leads to a stream passage. We followed this but could not
pass a sump shown on the KHE map as a deep pool. This was only about 30 metres
in. Apparently, either it was a dryer time of year when they were in there, or
they ducked through.
S. verleyi and N. farri were present in the passage. Eleuths were using
the outer part of the cave. A GPS position was taken, and then we carried on
across the cockpit to find GH Two Cave.

Good Hope Two
Cave is the second of several stream passage caves found downstream of Mouth
Maze. There are two entrances: the Sink is located at the end of a seasonal
riverbed that starts at the rising of Good Hope One Cave; and the Rising is to the
northwest in a different cockpit. Access notes for both entrances will be found
in the introductory notes for this chapter.
The Sink was
found on the afternoon of April 2, and the Rising on May 13.
April 2, 2005
Team: Stewart, Conolley, Roggy, Slack
After we had
found the Rising entrance to Good Hope One Cave, we had generally followed the
riverbed that starts there, but with us not actually down in it, until it
disappeared below a saddle on the northwest side of the glade. At this point,
another streambed joins from the east, after a series of muddy sinks, and low
bedding-plane passages in the side of the hill. The drainage from the cockpit
is through a wide section along the bottom of the hill, and the actual entrance
to GH-2 Cave was not immediately apparent. In fact, it was not until our second
visit, on May 13, that we were sure of the position for the true entrance.
After scrambling
around in various low wet undercuts in the hill for a while, and not having
much luck, we decided to look further to the northwest in the cockpit bottom to
see what could be found. At 18 18 53.4 N, 77 34 36.4 W, 300 metres from the
GH-2 Cave sinks, we found what we determined afterwards is an unlisted sink at
the end of a stream. We didn't spend much time trying to find a way in, and
didn't have any success, but this site should be looked at again.
The time was now
late afternoon, and we had already been in several caves earlier in the day, so
we pulled the plug and hiked out.
May 13, 2005
Team: Stewart, Conolley, Slack
During the second
PiP expedition, we returned to Good Hope Glade to finish things off. Parking
again at the end of the Good Hope Road, we made good time on the hike to the
Rising of GH-1 Cave, and this time walked right down the bottom of the riverbed
that starts here, (mostly dry at this time). The garbage was really quite
something - bags, bottles, old shoes, you name it, was littered along the
entire route. No one lives or farms in this glade, (it floods), so obviously it
was all coming from the sink of the Mouth River, after having travelled through
Mouth Maze, and GH-1 Cave.
This attempt, we
found the actual entrance to GH-2 Cave, but the time of year and the flood-risk
suggested that we not go in. A couple of things can be noted: There is not much
silt at the entrance to the cave, because the flow in is through a very wide
section of bedding-plane at the bottom of the hill, and it has not been
concentrated like at the GH-1 Cave sink. The garbage fed to this point is not
being trapped to any extent at the entrance to the passage and much is washing
in. Despite there having been much rain in the weeks before, with the Mouth
River quite active, the riverbed through the glade was still mostly dry -
apparently, the phreatic zone had not yet risen enough to cause a surface flow.
After getting a
GPS position, we worked our way through the saddle above the sink to find the
Rising.
The saddle that
needs to be crossed is a little dicey to get through. A vertical cliff of about
15 metres is directly above the sink, and on either side the hill is only
slightly less steep. We went to the right, (east), and had to fight our way
around trees, including Cowitch, perched on the steep slope. The rocks are
loose. I was the first through this, and got Ivor to throw me the etrier so
that I could tie it to a tree at a safe point for the others to use - I was
somewhat concerned about the others taking a very nasty fall. The downward side
was easier.
Once through the
saddle, we went down into the cockpit, and swung left, (north), to look for the
riverbed that we expected to find starting at the Rising of GH-2 Cave. We found
it where the KHE area plan indicated it should be, about 300 metres from the
saddle.
At the top of the
riverbed was a fissure type entrance, (strongly jointed), with a pitch of some
metres dropping into the rock. This matched what we would expect for the rising
of GH-2 Cave, going by the KHE account. We didn't have a rope, not thinking
that we would need one, but we had a very long etrier, (10 metres). We tied this
to a tree, fed it into the hole, and Ivor headed in. The etrier didn't get him
quite to the bottom, so he wasn't able to explore up the passage.
Although we did
not get into the passage, we would expect that S. verleyi would be present,
since they are in all of the other stream passage caves in Rock Spring. N.
farri would also be possible. A GPS position was taken at the entrance, and
then we followed the riverbed downstream as best we could, (we couldn't walk in
it most of the time, because of trees washed/fallen in, and mud), until we
reached the sink to Far Enough Cave.

Notes: RS Stewart
The morning had
started with Carambie Cave, and after finishing it we moved up the Good Hope
Glade road to start our search for Swanga, Pool, Crayfish, and Iron Maiden
caves. They were all listed as being accessible from this side of the bush,
arrayed across towards Printed Circuit Cave. We had linked with a friendly
local man, Gary, soon after parking at the bottom of the Good Hope Glade road,
(near wpt 203), who not only knew of Swanga Cave, but would take us there, (no
charge - it turned out he wanted our assistance in exploring another cave he
knew of and was curious about). We hiked up the road, (a very minor rural road,
more of a lane), until at the end it forked off into two trails. The left
branch, we were told, headed to the Good Hope Glade, where we would search for
several other caves later in the week. To the right, we were told, was Swanga.
This seemed odd to me, because we were now well past the listed position for
Swanga, and heading even further away. Nevertheless, we followed him down the
trail to see what could be found. Whatever it was, it would be unlisted.
After passing
through a saddle, we descended into a large bottomland that was fairly
bushed-up on the slopes. Once down, we swung to the left, and a short distance
ahead we came to an enormous, shallow shelter-cave hard against the side of the
valley, (wpt 195). This, we were informed, was Swanga. Now, we knew that the
listed Swanga is a small stream-passage cave, with a small entrance, and this
of course in no way matched what we sought. We hiked closer into it and had a
look at things.
At the bottom of
this giant shelter, there was an obvious seasonal stream-rising, currently
impenetrable due to mud/silt. It was not active, but it was dry-season so this
was no surprise. The effects of the last rising were certainly visible, though,
in the form of dried mud covering a large part of the bottomland, and extending
a good distance up the trunks of trees found in the valley immediately below
the cave. This appeared to be, once again, a result of Hurricane Ivan, some
months before, as seen at Mouth Maze. Hurricane or not, it is apparent that
this rising is terrifically active at times, unlisted, and has its source
undetermined.
I questioned our friend carefully about the name of this cave, and also
asked if he knew of anything in the area where the "real" Swanga was
supposed to be that had a small stream-passage type entrance. Indeed he knew of
such a cave, locally known as "Banga". After getting a GPS position,
(wpt 195), for this new "cave", we hiked back out to the end of the
lane where the fork is found, and then back towards where we'd parked, and much
closer to where the "real" Swanga was listed to be.
We're listing this new site with a low vulnerability, because it is
just a large shelter with no bat-roost, etc. There is a possibility of Sesarma
spp in the passages/bedding-planes that feed the rising.

The two Harties
caves are in the Rock Spring district, in hills on the west side of the Mouth
River. In the distant past, they were part of the active river itself, but this
has now moved lower and to the east. Our visit to these caves was made as part
of the Parks in Peril Project, under contract to The Nature Conservancy.
In the morning,
our team of four had separated into two groups and carried out further
exploration of Printed Circuit Cave, with much success. In the early afternoon,
we had reassembled in preparation for the Harties caves, and then Mouth Maze,
at the end of the Mouth River. We were fortunate in having a relative of Miss
Buckle, the lady from whom we were renting rooms, assist us in locating the
entrances to the Harties caves. Although they were at no great distance from
Printed Circuit, finding them ourselves would have consumed time that was
better spent inside, rather than outside, the caves.
The main
entrances to both caves can be reached either by a track to the north, or
through farmland to the south. This first visit was done from the north, by
taking the side-trail that branches off from the main Mouth River trail, and
ascends the hill to the west before curving back to the south. In a
collapse-feature, now forming a saddle in the hill, entrances to both caves can
be found, with Harties 1 to the SW, and Harties 2 on the NE. We began the visit
by entering Cave-1.
There are two
branches to Cave-1, one of which, the northern, leads to another entrance at
the NW end. The main entrance, at the collapse, is medium sized, some 5m high
and 4 wide, and it is only about 10m to where the two sections of the cave
diverge. Once in, Dietrich and I took the northern route, and Ivor and
Elizabeth the southern. We passed through fairly quickly to find the far
entrance, (larger than the main entrance, facing west on the side of a hill),
and then after getting a GPS position, (with some difficulty due to the
entrance topology), we worked our way more slowly back the way we had come to
search for inverts. Several Sesarma spp. were observed, (crabs), and a leg was
collected from one for genetic analysis in a small pool near the far entrance.
Several pools were located in this northern section of the cave, with the
collection pool being one of the smaller and thereby offering easier temporary
capture of a crab. As with most of the other caves we observed in the district,
Periplaneta americana were present, although not in great numbers. This was
possibly associated with the relatively small bat-roost that was in the cave,
and a correspondingly low quantity of the guano which these roaches seem to
enjoy as one of their main food sources. The roost itself was estimated to have
numbers under 500, and to be largely made up of fruit-bats. About 75% of this
cave is twilight zone, and it has been visited often through the years because
of the ease of access. Guano mining has occurred periodically, although the
deposits are quite small at the current time and it would be suspected that it
would primarily be mud with some fertilizer leached into it that has been
collected. It is difficult to know whether this roost was larger in the past,
and has been lessened by human visitation, but during the time of our
observation it was of no great extent and available roosting space was not
being fully used. Trog inverts that might have been expected were not seen,
(cave crickets, spiders, amblypygids), and this could perhaps be due to limited
food resources and P. americana out-competing other scavengers.
The presence of
Sesarma verleyi is interesting, because it indicates that there are fissures
that connect the upper chambers to a lower section closer to the phreatic zone.
D and I returned
to the collapse-feature at the main entrance, where I obtained a GPS position,
and then we waited for Ivor and Elizabeth to join us. After a while, they
emerged from their branch of the cave and reported having found a small, but
long passage that they had followed for a great distance without reaching the
end, that did not seem to be indicated on the KHE map from 1965. This discovery
warrants a return visit at a future date.
We now entered
Cave-2, and journeyed in for about 30m until a deep gully was reached that
required vertical gear to descend. The gully seemed to show that formation of
the cave had taken place in two separate stages, with the larger higher
chambers being first, and then an active stream cutting a gully through the
floor of this at a later point. The process does not seem to have been steady,
but instead punctuated, there being no gradual transformation from the older,
higher chamber, to the gully which was carved into the floor. It appears that
many thousands of years separated these two stages of development, with an
extended dry period in between, (this perhaps occurring during the last glacial
age).
Because we did
not have vertical gear with us this day, we decided to make a return visit
later in the week to Cave-2 and move on to Mouth Maze cave today.
The garbage noted
consisted of bottle-torches, fertilizer bags, etc.
We are listing this site with a high vulnerability due to the bat-roost
and the frequent disturbance by visitors. This cave was probably more
interesting biologically in the past and should be allowed to recover. We'd
suggest that the guano mining stop.
Harties Cave-1
March 30, 2005
Notes: DK Roggy
Stefan and myself walked through Harties 1 cave from one end to the
other, following the main part of the cave around to the right and to the other
entrance. We found that the two entrances were not far apart. I explored a bit
within the middle of the passage, scrambling up an incline and finding myself
in a perhaps 1m diameter crawlway. I went a little way and came across a green
beer bottle. It seemed that a local had come this far before and left this item
to mark how far he'd come. Perhaps if I'd gone further on, I might have run
into the same passage that Ivor and Elizabeth had found. Further exploration is
needed.

This site has a large bat-roost. Access is more difficult than Harties
Cave-1. |
Team: Conolley, Slack, Newman
Notes: RS Stewart
The report I
received from the three of the crew who visited the cave while Dietrich and I
were finding Farmyard Cave, indicates the following:
A large bat-roost
is found well into the cave, in the dark zone. This in the further, lower
sections, with guano extraction not reaching this point, but being limited to
the outer, upper section. American roaches are present, but for other inverts
the observations were not thorough, and are uncertain.
The three of them
seem to have found the cave quite interesting in a "caving" way, and
were impressed. There is a possibility that the cave is not thoroughly explored
yet.
I will quote from
my notes for Harties 1, on Mar 30 when I briefly visited Cave 2:
We now entered
Cave-2, and journeyed in for about 30m until a deep gully was reached that
required vertical gear to descend. The gully seemed to show that formation of
the cave had taken place in two separate stages, with the larger higher
chambers being first, and then an active stream cutting a gully through the
floor of this at a later point. The process does not seem to have been steady,
but instead punctuated, there being no gradual transformation from the older,
higher chamber, to the gully which was carved into the floor. It appears that
many thousands of years separated these two stages of development, with an
extended dry period in between, (this perhaps occurring during the last glacial
age).

Team: Stewart, Conolley
Notes: RS Stewart
We had problems
finding this cave initially, and had had no luck during our stay at Rock Spring
in late March. Dietrich and I had looked for it a couple of times to the east
of Swanga, on the same side of the Good Hope road, and as it turned out, it was
on the other side. The entry in JU is somewhat deceiving, as it states, "East
of Mouth River sink in the floor of a large glade". The large glade is
apparently the rising entrance, because the sink is in a narrow valley between
hills, and both entrances are a long way from the Mouth River. I finally was
able to locate the sink entrance with the aid of the Rock Spring area plan,
(found in the introductory notes to this chapter), using GPS waypoints that I
knew were definite to calibrate the plan, and then plotting it on the topo map,
and then moving the resultant positions into the GPS prior to the search. This
worked well, and on May 21 Ivor and I found the entrance only 35 metres from
where I'd calculated it to be.
An entrance about
1.5 metre wide, and 2.5 high, takes the water of a small stream. There was a
minor flow when we there. Inside, it widens and runs through bedding-planes
until after about 30 metres the ceiling lowers towards the water. To the left,
(north), there is a section of small breakdown chamber. When we reached the
point where the airspace was only about 30 cm above the water, we decided to not
pursue it and stopped there. There was detritus stranded on the passage walls
right to the roof, and it was rainy-season.
Neoditomyia
farri, were present, but I saw no Sesarma. I would suspect that if we had been
able to go further into the passage we would have found them, since S.
verleyi are found in most of the other Rock Spring caves, along with S.
windsor in Printed Circuit and Harties #1.
There was very
little silt in the cave, inside of the sink, and it appears that the thick
vegetative cover outside is responsible for this.
We have not found
the rising for this cave yet, but by comparing the KHE map to our position on
the topo map for the sink, we would suggest that it will be found in a cockpit
near 18 18 46.3 N, 77 33 54.8 W.
We are listing this cave with a medium vulnerability because if the
land-use at the sink were to change, this cave could go the way of Farmyard and
be affected by siltation.

Mouth Maze is
located at the sink of the Mouth River, in Rock Spring, Trelawny. The JCO visit
to it was made as a part of the Parks in Peril Project, under contract to The
Nature Conservancy.
We were fortunate
in there having been very dry conditions for the two months prior to our
exploration of this cave, because during rainy times it is potentially quite
dangerous. At the time of our visit, dried mud could be seen stuck to the
trunks of trees in the valley just upstream of the main entrance, over 10m
high. This was probably left over from Hurricane Ivan, but according to local
reports, even in a normal rainy-season the valley floods up much higher than
the entrance to the cave. This is primarily due to the valley of the Mouth
River suddenly ending at the entrance to the cave, (a blind-valley, as it
were), so that water backs-up to a considerable height before it manages to
drain entirely through the Mouth River Sink, and the Maze.
The cave is a
labyrinth, and it is large and impressive. The outer chambers, close inside the
main entrance, are 10's of metres high and wide. This section takes much of the
river flow in flood-times, and has been eroded greatly as a result. Further on,
the cave branches into a number of different passages, and they are generally
smaller. It requires diligent flagging to avoid getting lost. Any who read
these notes and contemplate a visit to Mouth Maze are advised to not take it
lightly. There are none in the district who are familiar with the cave, and if
you have problems, no one will find you, (even the JCO would have a hard time
locating lost cavers in this great network of passages).
Our team had
already visited several caves this day, and this was to be the last. The hike
out would be easy, on a good trail, and we had no great worries if we had to
make the trek back to Rock Spring in the dark. At about 3:00 PM, after the
Harties caves, we were at the downstream end of the Mouth River and looking for
a way through a giant pile of debris that had been heaped-up in front of the
entrance, apparently by the floods of Hurricane Ivan. Bamboo, tree-trunks, and
assorted garbage, lay in a great mound, tens of metres across, and at least 10m
high, in front of where the main entrance to the cave should be. Stepping carefully
over and around this, we finally found a way in. I am unsure of what the
entrance looks like when it is clear, but on this day all that was visible was
an opening a couple of metres high and wide. This was soon passed, and we were
in the cave.
I must admit that
it didn't take long for me to become somewhat concerned about what lay before
us, and I passed the word to the others that we would be very, very careful in
this one. Part of my reason for feeling this way was that the initial chambers
were large enough that we could not see side-passages well, but we knew that
they were there in abundance. It seemed easy to lose track of flags in this,
and miss turns on the way out. In addition, everything was coated in slimy mud,
and footing was treacherous, especially over the massive slabs and boulders
that served as the floor in much of this first part. Moving slowly, we carried
on straight ahead to find the closest of the other known entrances. At the far
end of what seemed to be the main part of the large entrance series, a scramble
up a muddy slope led to a breakdown chamber with lightholes at the top. One of
these was reached by me via a climb up boulders of about 13m, and I came out
high on a hillside with, amazingly, dried mud in place on the trees that grew
at the entrance. I could not tell whether the waters had sunk or risen here,
but whichever it was, I was a good distance higher than the main entrance and
the first large chambers found within. The amount of water that must have been
involved in all of this was incredible.
After getting a
GPS position at the lighthole entrance, I climbed carefully back down to rejoin
the others, and then we retraced our route until we came to a large
side-passage on the SW that had been passed on the way in. I believe this was
the beginning of the so-called "Bloodbath Passage" shown on the KHE
map. This was followed for about 50m, and then another side-passage was taken,
to the NW. We moved through this section, (I believe we were in the "VW
Passage"), and worked our way along, flagging often, until we finally
entered what I believe to have been the "Sludge Thing", (this after a
slither through the mud in a low passage, first pushed by Elizabeth). We now
came into a long sinuous streamway that we followed for well over a hundred
metres. Soon after we had entered this last passage, we had detected a slight
flow of air, (this being a big part of why we had carried on), and there was no
doubt that somewhere ahead was another entrance. Unfortunately, the great
amount of silt deposited in the water, through which we splashed, was steadily
supplying noxious gases as we churned things up making our way forward. I began
to keep track of how I felt, so that I might be aware of the effects of high
concentrations of CO2, or other gases. I will go into more detail on this
further on, but it must be noted that this entire cave had experienced a
massive flood during Hurricane Ivan, and it was heavily silted, and full of a
great amount of organic debris, such as bamboo, logs, and branches - in short,
there was a lot of actively rotting stuff in this cave, and conditions were
substantially different than when the KHE team made their visit in 1965.
My thoughts in
this part of the cave were that we were headed for an entrance, the airflow
should improve as we got close to it, and because we had taken time to look for
inverts on the way to where we were now, we should make speed and find the way
out, and fresh air, somewhere ahead of us. I had a walkie-talkie with me, and
the others who were now some distance behind me had the other. It seemed to me
that if I were out front and pushing on at a somewhat faster pace, that the
rest of the crew would also move at a faster pace, copying my example. This did
not turn out to be the case, and after a short time I recieved a call, via a
signal bouncing up the passage to reach my walkie-talkie, informing me that the
others wanted to consult on things and desired my participation. There was some
concern on their part as to whether we should carry on or turn back, since they
too were not happy with the state of the air in the passage. I returned towards
them, and we linked as they came up towards me. A quick discussion decided
things, and we agreed to turn back. Time was getting late, we were a long way
into a complex cave, and the atmosphere was rank. I went with the majority
decision, which was to pull the plug, and we headed back out the way we'd come.
We successfully retraced our route, and were again at the main entrance not
long before sunset.
Observations
follow:
If parts of this
cave have been used by bats as a roost in the past, the flood event during
Hurricane Ivan took care of that, and also washed away any evidence of it
having happened. Considering the regular, "normal" seasonal floods
that enter this cave, I doubt that it is ever used as anything but a temporary
roost by fruit-bats.
There was a
surprising degree of invert activity, apparently fuelled by the enormous amount
of detritus that has recently been rafted in. At least several of the species were
troglobites, (identification underway), and others are suspected to be
terrestrial, rafted in and continuing to survive on the accompanying detritus.
The trog inverts apparently survived the floods by hiding-out in small cracks
at the top of the passages and chambers. Most remarkable of the rafted
terrestrials was a termite nest, complete with live termites, that was about
60cm across, sitting on a rock, perfectly rounded by its watery travel into the
cave. The logs and bamboo that were present were continuing to enable the
critters to survive. Of the over 100 caves I have visited in Jamaica, this was
the first one I've ever seen with a termite colony, other than in the twilight
zone close to the entrance. The location of the termite nest was hundreds of
metres from the nearest entrance, and when the last of the logs are rotted
away, one can safely assume that the termites will be history.
Many Sesarma spp.
were present, but no shrimp were seen. This does not mean that they weren't
present - we might have just not seen them - but if they are in Mouth Maze the
numbers are not great.
I must note again
the great amount of debris that is currently in the cave. This not only
includes a great quantity of organic material, but also a vast collection of
garbage that was washed in at the same time. It is interesting that there was
little in the final passage, (Sludge Thing?), indicating that its source is
relatively garbage-free. Much of the rest of the cave that we saw had been
flooded by the waters of the Mouth River, and had collected a kilometres worth
of external trash prior to feeding it into the entrance. The cave truly needs a
good clean-up at some point before all the assorted buckets, bottles, and bags
start to lodge and collect silt in smaller downstream passages. This process
could very possibly interfere with the historical levels of drainage through
Mouth Maze, (that allows the water to leave the entrance valley and come out at
the downstream risings), and back things up even more in the future.
This day had been
one of the most productive so far this expedition, and although somewhat
physically tired, I felt quite pleased and didn't want the day to end yet.
After having a bite to eat at Miss Buckle's, I made my way down the road to a
friendly little bar that I knew of, and spent a couple of hours in the good
company of some of the local residents, while being served cold Red Stripe by a
quite attractive, very friendly woman. At 10:00 PM, with my sense of
responsibility kicking-in, I wended my way back to Miss Buckle's, brushed my
teeth, took out my contact lenses, and then had a very satisfying,
well-deserved sleep.
We're listing this cave with a high vulnerability, due to the great
amount of garbage being washed in, and the heavy siltation. At present, post-Hurricane
Ivan, it's a total mess in there. The only thing comparable I've seen is Rota
Cave in St James, which also takes flood-waters full of trash.
Mouth Maze
March 30, 2005
Notes: DK Roggy
We found our way to
the entrance of Mouth Maze. It was a large jumble of bamboo and other items
that had floated on the river and remained on the surface when the river sank
down into the cave. I scrambled around on the mass of wood and pulled some
things out of the way, until I found the entrance. Placing a long, fairly fresh
length of bamboo down into the entrance, I used it to assist me in scrambling
down the boulders at the entrance.
We came into a very large
chamber strewn with boulders and debris that provided us with 3 options for
which way to go. We proceeded forward, pretty much due west as I remember it.
After about 100m we came to a collapse that had at least 2 light holes in it.
Stefan scrambled up and out and obtained a GPS position.
After that we backtracked a
bit and took a passage to the south. We went for some while on this path,
encountering logs every now and then. Eventually we came to a rough, eroded
channel that was perhaps 10-15 feet tall and 2-3 feet wide. It looked really
difficult, and much different from what we'd been walking through. I noticed no
silt accumulated in it and the walls glistened with moisture. We decided not to
take this passage, turned left, slid through a muddy crawl, then emerged in
another stream passage that was fairly open and promising.
Stefan started getting worried about whether he was having symptoms of breathing too much CO2, or some other gases. When he asked us how we felt I wasn't sure if I was dehydrated or what, but felt a mild headache. We'd been going for some time inside this labyrinthine cave, and although we'd been flagging all along, I was feeling like we'd gone for such a long time that I'd rather just turn back. When I informed the group that the time was 16:45, that decided it. We turned back, leaving behind one flag at our farthest point. I labeled it "JCO, 30 Mar, 2005". Perhaps someday in the future we will come across it again.

This cave was
visited immediately after Crayfish Cave. We entered through the rising
entrance, and exited from the sink entrance. We noticed soon after we were in
the passage that siltation was low. When we came out at the far end, we found
that the seasonal streambed that feeds into the cave had a very dense cover of
bush and shrubs, with the more open areas covered with tall weeds. This was the
only sink in the district that we found in this state, and it was the least
muddy cave. The floor of the passage was clean rock, and rimstone pools held
clear water. This cave can be contrasted well to Farmyard Cave which is not far
away. Farmyard takes most of its flow from cultivated land and is almost
entirely choked with silt.
The passage held
no rafted-in garbage. Invasive roaches were not present.
Sesarma verleyi
were present, as were N. farri, but we saw no other trogs.
We are listing this site with a medium vulnerability. There is no
immediate threat, but if land-use changes upstream, it will be greatly changed
by siltation.

Notes: RS Stewart
This was the
third day of the first expedition engaged on the Parks in Peril Project, under
contract to The Nature Conservancy - Jamaica, and the first of several days
that would be spent finding and assessing the many caves of the Rock Spring
district. This district had been a high priority for the first TNC expedition,
because many of the targets are river caves and are only accessible during the
dry-season. We were fortunate in there having been an extended drought in the
area for the previous two months, and high water levels were not a concern
during the visit.
The night before
had been spent in Windsor by Ivor, Mark, and I. After a swing through Falmouth
to drop off Mark, who needed to return to Kingston, Ivor and I made the drive
to Albert Town to link with Dietrich and Elizabeth. They would remain with the
team for the rest of the expedition. Not long past noon, we were all assembled
and en route to find "Miss Jasmine Buckle", at Rock Spring, who had
been recommended to us by Adam Hyde as a possibility for renting room/s. Road
construction near Albert Town resulted in a detour via Burnt Hill, and this
combined with a number of stops for info in our search resulted in us not
getting to Miss Buckle's until about 2:00 PM. Another hour was then consumed by
negotiations and considerations. At 3:00 PM, we finally got to work.
Miss Buckle's is
ideally suited as a base for investigation of the Rock Spring Caves being
located in close proximity to many of them, as can be seen on the map attached
to these notes - her house is about 10m from waypoint "025". All of
the other points marked on the map were cave entrances found by us, and GPS
referenced, during the next four days, with the exception of points 025 and 028
which are calibration points. This might give a general idea of how much ground
we covered, and what we were able to accomplish. Of the fifteen caves, and
multiple entrances, that we would hit, the first cave of the bunch, the one we
were about to visit today, Printed Circuit Cave, (known locally as Rock Spring
Cave), was the closest and most easily found, and a cave that I was already
familiar with, from a visit in 2002. It is a pleasant ten minute walk from Miss
Buckle's, and we were soon at the main entrance, called "Sober
entrance" by the KHE, and shown in their map, which is reproduced in
Jamaica Underground, with this designation.
Our visit
coincided with a get-together and cook-out by some of the younger people of the
community at the main entrance, (a very pleasant spot, right by the river and
well suited to it), so we stopped to exchange pleasantries for a few minutes
before we headed in. I would again meet many of them later in the week, in the
evenings at local pubs, and found this event served well as an introduction.
There were a few who were curious about what we were doing, and our answers to
their questions resulted in us not being seen as visiting tourists, but as
researchers who were in the field, and on the job. Time-pressed, though, so
with a "likkle-more", we turned on headlamps and entered Printed
Circuit Cave.
Printed Circuit
Cave is a labyrinth of active stream passages. It serves as a tributary system,
taking water from several upstream sources, and then at the downstream-end
feeding it into the Mouth River. It is at times used for tourism by the South
Trelawny Environmental Agency, with visitation restricted to several small
passages that lead from the Sober Entrance to the main collector, and the main
collector itself in its closest section. There are in total about 10 entrances,
although not all of these are currently accessible due to rafted debris and
siltation. My intention for this visit was to get to the main collector, then
follow it upstream to investigate several small feeder passages. This would get
us beyond the areas that experience regular visitation, and also get us into
the kind of habitat that cave decapods seem to prefer, i.e. a series of small
pools with a minor flow. This was accordingly done, with us ultimately entering
the "Positive Stream" passages. Observations follow:
The main
collector is serving as a bat roost for at least fruit-bats, with numbers
estimated to be in the 500-5000 range, although probably at the lower end of
this. Because the roosting space is restricted to the main collector, which
constantly has water in it, guano accumulation is restricted to the passage
walls, occurring as spots on the lower sections. Periplaneta americana are
present, (introduced roaches), but not in the great numbers that would be found
in roosts with thick beds of bat guano. Cave crickets, (U. cavicola),
are present, although not in great numbers. In the smaller passages upstream of
the collector, a species of trog araneae, (spider), was observed with which I
am not yet familiar, (identification is underway). Two species of crab, S.
verleyi, and S. windsor, are present. Surprisingly, we saw no N.
farri, (predaceous fly larvae), although it must be strongly suspected that
they are present in passages that we did not visit. Buffo marinus are present
in the small passages that lead to the main collector. No E. cundalli were
heard at the main entrance, although this might be associated with the very dry
conditions, rather than the area outside being regularly used for small
bashments, (get-togethers).
After visiting
the smaller upstream passages, we returned to the main collector, traveled past
our entry passage, and then downstream for about 100m. I found myself well in
front of the group, and took the opportunity to explore a small dry passage
feeding in from the direction of the Mouth River, as does Sober Entrance, and
found evidence that access has sometimes been gained via this route, (old
coal-oil lantern). I suspect that it leads back to the main entrance, via the
passages shown on the map that are to the northwest. After venturing about 30m,
much of it crawling, I returned to the main collector where the others were now
within talking distance. It seemed that we'd done about as much as we could in
this section for the moment, and there were more entrances to the cave that I
hoped to locate from the outside, so I pulled the plug and we began to make our
way out.
At about 6:00 PM,
we were again outside at the Sober Entrance. It was decided that we would split
into two groups of two and search upstream, and downstream, for more entrances.
Dietrich and I took the upstream part, and headed southeast to see what we
could find. We skirted around the low hill that rises over the cave, looking
for seasonal streambeds that might feed into the system, finding nothing on the
Mouth River side. Once around to the east side, we came into the back of a
small farm, with house, and stopped to call out a "hello", so that
the owners of the land would know that there were two men with helmets on their
heads wandering through their yard. A friendly woman in her 30's appeared, and
after hearing our explanation of what we were doing, directed us to a small
hole near-by that might be one of the entrances that we sought. As we moved in
that direction, asking if we were going the right way, the lady of the house
volunteered to show us the route, and led us about 100m to a small entrance at
the downstream end of a seasonal streambed. Good stuff. We thanked her greatly,
and she then left us to it. I wish that I had noted her name, as we were to
meet her again several times during the visit, as we searched for entrances,
and her help was greatly appreciated. I remember exactly where her house is,
and will try to drop by some time, get her name, and then amend these notes.
The GPS point
that I recorded for the position is time-stamped 6:28 PM. Dietrich had been
having some trouble with his headlamp, and it was getting close to sunset, so
it was decided that I would go in by myself far enough to see if the passage
went anywhere, then rejoin D and return to Miss Buckle's. The entrance is
small, about 1.5m high and wide, and faces southeast. It seasonally takes
water. Within 5m of the entrance, I reached a low point where there was only
about 40cm of airspace, this through stalactites, so that I almost had my chin
in the water. I worked my way past this, and found that the ceiling soon got
higher. I pushed on, following a sinuous passage, in places 3m high, and 2
wide, and all of it with water on the floor, that just kept going. The plan was
for me to have a good enough look to see if this was one of the Printed Circuit
entrances, and to do this I needed to follow it until I hit side passages that
I could use to compare to the map created by the Karst Hydrology Expedition,
(KHE), in 1965. It took about 150m for me to hit any other passages of
consequence. At this point, a t-junction was reached where the passage I
followed connected with a larger passage, some 4m high and 3 wide. This
junction was very nice to look at; the passage I had taken ended in a large
rimstone pool about 2m above the passage it joined, and a scramble down led on,
upstream to the right, and downstream to the left. This gave me something to
work with, so I called it quits and retraced my route. Subsequent work, and a
return visit the next day, showed that the entrance we'd found was the one near
Farmyard Cave, and this was indeed part of Printed Circuit Cave.
When we linked with Ivor and Elizabeth at Miss Buckle's, we heard that
they had had some success downstream, and were in a good position to tackle it
again in the morning. This was how the next day would begin, with Ivor and
Elizabeth searching out the downstream entrances, and Dietrich and I
re-entering the cave via my route to see what we could find.

Notes: DK Roggy
This was my first day of
caving for the Parks in Peril Project, under contract to The Nature Conservancy
- Jamaica, and I was plus en retard. We spent some time securing our
accommodations in Rock spring and then went as a group into Printed Circuit
Cave. Over the next couple of days we discovered that this cave was called Rock
Spring Cave by the locals, but some also called it something like George Lawson
cave, or something similar. I didn't write it down, and thus have forgotten it.
We went in through the main
entrance, called the sober entrance and encountered a bunch of locals in front
of it, engaging in some kind of cook out. We chatted a bit and then went in.
Further in the cave we encountered some locals touring the cave with kerosene
bottle torches.
My only notes of this first day in this cave are
that it was wet and muddy. After we all came out of the cave, Stefan and myself
searched around above ground for other entrances to the cave. We went over a
rise and found ourselves in a patch of yam cultivation, where a woman directed
us to one cave entrance. Stefan did a little preliminary investigation of what
we'd been shown, while I waited outside with headlamp problems. I made note of
the time that he was inside, and when he came out it was dusk.
Printed Circuit Cave
March 30, 2005
Notes: RS Stewart
The day began
with a return to Printed Circuit Cave to continue our search for entrances to
this complex river cave. The day before, we had entered the cave via the main
entrance, conducted the assessment, and then finished off the afternoon by
hunting for more of the known ten entrances. Dietrich and I had found, and
partly explored, a passage that we believed to be part of the system, and this
morning we would return to it and carry things further.
We had decided to
split the team into pairs for the morning, and then link back up for the
afternoon. Ivor and Elizabeth would explore the downstream terrain above
Printed Circuit, and D and I would hit our previous passage, and then search
for other entrances in the upstream areas. Dietrich and I and had soon made the
hike to re-find our first target, and had then headed in.
Facing southeast,
a smallish entrance, (wpt 183), takes the waters of a seasonal stream. Within
10m, the passage becomes low and wet, requiring crawling through water, between
stals, with only enough airspace to keep one's chin barely above water. Beyond
this mildly intimidating section, the passage becomes larger and easier. The
day before, I had followed it until I had reached a T-junction, and then
returned to the entrance. This time, once we hit the junction, we climbed down
the 2m drop into the joining, larger passage, and headed in the upstream
direction. I suspected that we might have come in from the Farmyard entrance,
in which case heading upstream should pop us out at a pair of entrances to the
east.
Dietrich and I
made good time, following our new passage as it slowly became somewhat smaller,
feeling a current of air moving past us, and feeling very optimistic about
things. Within 30 minutes of having first entered the system, we saw light
ahead. This was very good, since it matched what we thought should be happening
if we were truly in Printed Circuit, and since we would also not have to return
to our initial entry-point. The last 50m of our travel from the junction had
involved much crawling over rather painful rock and formations, and we were not
keen on having to repeat it. As I got close to the light ahead of us, my
optimism faded as I saw large boulders blocking the exit. There were small gaps
around them, but on the other side could be seen logs and other debris that had
apparently been washed into what looked like an entrance pit, during Hurricane
Ivan. I suggested to D that he have a look at it, and we both crouched in the
final metre of the passage and searched for any possible egress. To the left,
the gap seemed just large enough to squeeze through, but it had a large log
jammed across on the outside. To the right it was more clear, but probably too
small. Dietrich took the initiative, and began to try to clear the log from the
opening on the left.
D was to do great
work this day. By using a smaller branch that he found, he levered, pried, and
pushed the log further and further from the gap. After some fifteen minutes of
this, he finally had things clear enough to attempt to squeeze through. He
wormed his way in, and up, and gradually moved away from me. I cheered him on,
and he was soon out. Inexplicably, I heard him say, "I bet you always
wondered where white people came from, didn't you?", which brought a laugh
from me although I had no idea what he was talking about. I followed through,
finding it surprisingly easy thanks to D's efforts, and after scrambling out of
a very small overgrown pit, saw before me two small children staring
open-mouthed, while a woman, their mother, looked-on with a smile on her face.
D's comment while climbing out suddenly became clear; I laughed much harder
this time.
About five metres
away was the second opening of the double-entrance that we'd hoped to find. We
indeed had things sorted out for this part of Printed Circuit, and had made
good progress. The other opening of the double-entrance held a pool and was
being used by people of the district as a water-source. While Dietrich had been
working away on clearing the route out, the family who had been there filling
buckets must have heard vague talking and thumping coming from what appeared to
be a small grassy depression. Eventually, two white men, with helmets on their
heads, had popped out of this. It was little wonder that the children were so
amazed at the sight. I like to think of the stories they must have told their
friends afterwards, and assume that our bizarre arrival from the underground
will be a memory that will stay with them for many years.
A GPS position
was taken, (wpt 184), which matched perfectly with the KHE map, and our other
two previously referenced entrances, and then D and I headed off to look for
the two "Positive Stream" entrances that are also noted in the KHE
map of the cave. We wandered through farmland in the right direction, and after
about ten minutes saw ahead of us a small building in the middle of a fine
field of coffee. Shouting out a "hello", we were answered by a man
who was working in the field ahead of us. A minute later, we had the pleasure
of meeting the farmer who tended this fine stand of coffee, who not only had no
problem with us crossing his land, but offered to show us a couple of holes
close-by. Although I got his name, I didn't write it down and have forgotten
it. I will try to get it again at some point in the future, and will then amend
these notes accordingly, for he was a great help.
On his land, at
no great distance from where we had met him, we were shown three other
openings, (wpt 185, 186, 187), that lie at the downstream end of seasonal
streambeds. These were all heavily silted, thanks to Hurricane Ivan, and could
not be entered without some serious digging. They were GPS referenced, and the
positions match the two "Positive Stream" entrances of Printed
Circuit, as indicated in the KHE cave map, and the upstream entrance to Swanga
Cave, (determined over the next few days after we had referenced other
entrances in the area). It was good that we found these from the outside,
because if we had reached them from the interior of the cave we could not have
exited from them and would not have been able to get positions. Part of what we
hope to accomplish is enabling monitoring of the studied caves, and if we
cannot find an entrance from the outside, the process is made much more
difficult.
It was now
approaching noon, the meeting-time with Ivor and Elizabeth for the afternoon
session, so we thanked the farmer who had helped us, found our way to the road,
and hiked back to Miss Buckle's to join the rest of the crew. Once we were all
linked again, we heard that the others had found, and GPS marked, several
entrances in the downstream area of Printed Circuit, so between the four of us,
we had knocked off about 6-7 of the entrances to PC, and made great progress in
just the first several hours of the day. We would now move on to the two
Harties caves, across the river from Printed Circuit.
The garbage found
in the cave is being carried in, (bottle-torches, scandal bags), and washing
in, (trash, buckets, etc).
We are listing this cave with a medium vulnerability. The tourism
taking place here is under the auspices of the South Trelawny Environment
Association, and they are sensitive to the delicacy and importance of
preserving the cave. The main threat is from siltation in the upstream sinks.
Printed Circuit Cave
March 30, 2005
Notes: DK Roggy
Entering the entrance that
Stefan and myself had found the previous day, we found ourselves in a low,
winding stream passage. Most of the time we were stooped over and a fair amount
of the time we were crawling or squatting. After about an hour we came to
another entrance. It was choked up with rocks and a couple thick logs. Using my
ingenuity as a civil engineer, I spent some time moving the rocks aside. I then
did my best to pry and pound the logs out of the way, using sticks and some
rocks where necessary for a fulcrum. I didn't want to have to go back out the
way we came, and ultimately we wanted to get a GPS position of this entrance,
so it made sense to do our best to try to get out this way. I managed to shove
one log aside, then another and squirmed out.
Two little children were
standing about 30 feet away, holding plastic buckets and looking at me with
wide eyes. I said "I bet you always wondered where white people came from,
didn't you?" and they just kept looking at me, dumbfounded. Stefan got a
real kick out of that.
We found that we'd emerged
at what appeared to be a place where there were two entrances that faced each
other. This more or less helped us to make assumptions about the layout of
where we'd gone in, where we'd come out, and where other entrances should be.
We proceeded north, up a rise and down into a field of coffee bushes. We encountered a farmer who showed us a couple more entrances. They both were filled with sediment and required crawling, at least as far as I went in.

On this third day
of our investigations of the caves of Rock Spring, Trelawny, things became
rather more confusing, although ultimately the day would be instrumental in
helping us to pin-down the many entrances that we were finding, to the listed
caves that they led to. In total, I don't know how many entrances we found in
the five days spent here, (I have yet to add them all up), but it was surely
dozens, distributed amongst twelve caves, (this not counting the caves closer
to Spring Garden that we also hit). Our steady GPS referencing would eventually
make things clear, later in the week, and today was to supply a valuable
data-point: the rising of Swanga Cave, from which we found and identified
several other of our targets.
The morning had
started with Carambie Cave, and after finishing it we moved up the Good Hope
Glade road to start our search for Swanga, Pool, Crayfish, and Iron Maiden
caves. They were all listed as being accessible from this side of the bush,
arrayed across towards Printed Circuit Cave. We had linked with a friendly
local man, Gary, soon after parking at the bottom of the Good Hope Glade road,
(near wpt 203), who not only knew of Swanga Cave, but would take us there, (no
charge - it turned out he wanted our assistance in exploring another cave he
knew of and was curious about). We hiked up the road, (a very minor rural road,
more of a lane), until at the end it forked off into two trails. The left
branch, we were told, headed to the Good Hope Glade, where we would search for
several other caves later in the week. To the right, we were told, was Swanga.
This seemed odd to me, because we were now well past the listed position for
Swanga, and heading even further away. Nevertheless, we followed him down the
trail to see what could be found. Whatever it was, it would be unlisted.
After passing
through a saddle, we descended into a large bottomland that was fairly
bushed-up on the slopes. Once down, we swung to the left, and a short distance
ahead we came to an enormous, shallow shelter-cave hard against the side of the
valley, (wpt 195). This, we were informed, was Swanga. Now, we knew that the
listed Swanga is a small stream-passage cave, with a small entrance, and this
of course in no way matched what we sought. We hiked closer into it and had a
look at things.
At the bottom of
this giant shelter, there was an obvious seasonal stream-rising, currently
impenetrable due to mud/silt. It was not active, but it was dry-season so this
was no surprise. The effects of the last rising were certainly visible, though,
in the form of dried mud covering a large part of the bottomland, and extending
a good distance up the trunks of trees found in the valley immediately below
the cave. This appeared to be, once again, a result of Hurricane Ivan, some
months before, as seen at Mouth Maze. Hurricane or not, it is apparent that
this rising is terrifically active at times, unlisted, and has its source
undetermined.
I questioned our
friend carefully about the name of this cave, and also asked if he knew of
anything in the area where the "real" Swanga was supposed to be that
had a small stream-passage type entrance. Indeed he knew of such a cave,
locally known as "Banga". After getting a GPS position, (wpt 195),
for this new "cave", we hiked back out to the end of the lane where
the fork is found, and then back towards where we'd parked, and much closer to
where the "real" Swanga was listed to be.
Partway back
along the lane, we turned southwest onto a good trail, and after a short hike
of about 100m, we came to something that looked much more promising. It was in
the general vicinity of where Swanga should be found, (although it was also the
same vicinity as several other caves, within the accuracy of the JU listed
positions). An entrance of 2-3m high, and 2 wide, held a pool in rocks in front
of it, and a minor flow of water issued forth. I took a GPS position, (wpt
204), we stuffed some things into a dry bag, and then waded in.
Beyond the
entrance, the passage extends onwards to the south, upstream. We followed this,
passing through places where the water is deep, and the ceiling is low, with
the passage never increasing in width more than 3m wide, or in height by 3m. At
times we did not do much more than keep our chins dry. Nonetheless, we moved
through in good spirits, carefully looking for trog and stygo inverts as we
went. After 100+ metres, we hit a sump, (part of a stream-passage where it is
so low that it is flooded to the roof), and began to wend our way out.
Once out, we were
still not certain which cave we had been in, Swanga or the nearby Pool or Iron
Maiden caves, but we had a position, knowledge of the inside of the cave, and
good biological observations. We pencilled it in as "Pool?", as it
seemed to be closest to that listed position, and assumed we would get it
nailed-down after more time spent searching through this part of Rock Spring for
the other entrances. Later in the week, once Pool Cave and Crayfish Cave had
been found, basing our search on a suspicion that this one had actually been
Swanga, everything fell into place, (except for Iron Maiden Cave, which we have
not found as of yet). The other nearby GPS marked entrances for Printed
Circuit, along with these positions, allowed us to match everything to the
unreferenced hydrological area map of the KHE expedition.
Before moving on
to the biological observations, I should again note the problem with the naming
of this cave. It is undoubtedly the listed Swanga Cave, but it is not the one
that the people of the district call Swanga. Locally, it is known as Banga
Cave. It is easy to see the origin of the confusion: the KHE were British, not
great at Patois, and when hearing the names Swanga and Banga, mixed in with a
lot of other "unintelligible" words, got confused and stuck the wrong
name to the cave. But, what to do about this? There is a large shelter cave
resurgence named Swanga. If a visiting researcher comes to the area, and asks
for Swanga Cave, as described in Jamaica Underground, he will be steered the
wrong way. What we did for our own clarification, when we had things sorted
out, was to refer to the large shelter as Big Swanga, and the listed cave as
Swanga-Banga. We suggest that these be the new names for these two different
caves.
Swanga-Banga is a
relatively healthy stream cave in its downstream section. There is some
siltation, but not a great amount. The upstream sink, found on a separate day,
is heavily silted and is taking surface water that runs through heavily
cultivated land. The area between the sink and the sump, (the sump reached from
the downstream end), is apparently acting as a silt-trap, with perhaps only
periodic flood-pulse events flushing it through. At any rate, during our visit
the downstream water was clear, and silt build-up was not critical, (to the
point of filling the passage in, such as at the nearby Farmyard Cave). Sesarma
spp, suspected to include both verleyi and windsor, were present in good
numbers, and samples of legs were taken that have been forwarded to Dr Schubart
for identification. As with the other Rock Spring caves, no shrimp were seen.
Neoditomyia farri, (predaceous fly larvae), are present in good numbers. One
juvenile Periplaneta americana, (roach), was seen, with the relative absence of
these pests directly related to the absence of bats and the associated guano.
No other macroinverts such as trog-spiders and cave-crickets were noted, this
being typical for a stream-passage cave with no bats in it, and occasional
flooding. Buffo marinus were occupying the outer section of the cave, close to
the entrance. E. cundalli, (troglophile frogs), were present in the entrance
area.
Formations are primarily
composed of flowstone, draperies, and rimstone pools. The cave, like others at
the same elevation in the same area, is formed along bedding-planes in the
yellow to white limestone transition.
We now moved on
to a cave that our new friend, Gary, wanted us to look at, one that he did not
know of a name for. As realized later, it was also a cave that we were not
aware of as being one of our targets, the confusingly named "Good Hope
Cave". I say confusing, because there are two other caves in the district
called Good Hope One Cave and Good Hope Two Cave. In preparing our information
before beginning the expedition, this one had somehow escaped being put on the
target-list. Separate notes for this will follow.
It was determined
later that the sink to Swanga is at the position found above, but it is
mud-choked. From the Rising end, where the entrance is found, the passage ends
in a sump. There is no access from the Sink end to the cave, and it is not
possible to pass right through.
We are listing this cave with
medium vulnerability due to the upstream siltation. The sink for this
cave is located downslope from well-cultivated farmland.
Swanga (Banga) Cave
March 31, 2005
Notes: DK Roggy
We
made our way from the roadside where Carambie cave was located, up a dirt road
and into the bush, with the assistance of a very helpful local man named Gary.
We were searching for Swanga cave and he told us that he would show it to us.
What he took us to was a tall shelter cave on the side of a valley, probably 60
feet tall. From the ground level at around the drip line the land dropped down
sharply into this large shelter cave. I made my way down the muddy, channelled
slope down about 40 feet, to where an entrance seemed to be located. It was
choked up with sediment. It seems to me that this is a river rising where water
comes up out of it to perhaps just below grade, then drops back down, causing
the eroded channels seen. This cave is referred to here as "Big
Swanga."
Next Gary showed us a small stream passage that he referred to as
"Banga." This cave turned out to be the "Swanga" cave noted
in Jamaica Underground, and the cave referred to here as
"Swanga-Banga." Gary accompanied us on our journey into this active
stream cave. The passage got low enough in places that only our heads were
above water. This was a new experience for Gary, and he dealt with it very
well. After traveling along the passage for about 25 minutes we reached a sump
and had to turn back.

Team: Stewart, Conolley, Slack
Notes: RS Stewart
This cave is
located beyond Far Enough Cave, two cockpits further on. The fastest way to
reach is it from the end of the Good Hope road, then along the track to the
west, then swinging north of the first ridge on a side-track. Further access
info will be found in the introductory notes to this chapter.
The cockpit where
the cave is located is very deep, and steep-walled. It's quite spectacular to look
at, and worth visiting even if you have no interest in the cave itself. You'll
need a rope/vertigear or long etrier, over 10m, to get down from the saddle
that leads to it.
We found the site
after visiting Far Enough, and Good Hope Two Cave. It was quite close, (only 30
metres away), to where the KHE area plan indicates it to be, but for some
reason the coordinates given in JU are very wrong, and plot it 1100 metres from
the actual location. We'd spotted the error before we began our search, so this
wasn't a problem.
The layout of the
cockpit, with the rising, stream, and sink that are found here is as such: On
the west side, low on a steep hill, a spring rises and falls over a series of
rock-steps a further 10+ metres to the floor of the glade. This is quite
pretty. At the bottom, the stream meanders in a deep streambed until it sinks
at the entrance to Too Far. Several other tributary streambeds join before it
gets there, coming from other risings that we did not see, but that appeared to
be southeast of the spring. On May 13, it was obvious that the entire glade had
flooded in the not-distant past, perhaps during Hurricane Ivan. Mud was
extensive, with flood meadow grasses growing through it. There are no trees in
the cockpit, so the flooding must be a somewhat regular occurrence.
During our visit,
early in the rainy-season, the water was too high to safely enter the cave
itself, but it was found and referenced. Unfortunately, the KHE map in JU does
not have the orientation included, but by using the entrance aspect, it would
seem that water is also entering from further to the northwest in the glade.
The cave was found to become too tight in the downstream section of the active
streamway, and a higher dry passage was blocked by a stal. The cave could perhaps
be pushed in the dry passage. Comparing the cave map to the topos suggests that
a rising might be found in a cockpit near WGS84, 18 19 20.0 N, 77 34 30.5.
The source of the
Too Far spring rising is not directly associated with the Mouth Maze to Far Enough
system, evident by the location in the glade. The catchments must be to the
west somewhere.
We are listing this site with a low vulnerability as the glade is
seldom visited.
