Nodewood Rising is a new addition to the Jamaican Cave Register, added by us subsequent to our visit to the Niagara district this day. It was pointed out to us by Delroy Wright, an employee of the flower nursery that owns the land upon which it is situated, while we were en route from Nodewood Cave 2 to Niagara River Cave.

The cave is found by the roadside, on the west, and faces east. An entrance of 2-3 m gives way to a small chamber cave, some 10 m across. In the central part, although dry during our visit, deep mud deposits indicate seasonal activity. In fact, it was the report that this cave resurges, given by Delroy, that prompted us to have a look at what would have otherwise been seen as an inconsequential shelter cave. Delroy had told us that, "it comes out of the cave, right up over the road, lots of water".

The source of this rising is probably the same system that begins in the Blue Hole Glade caves, and then feeds into the Niagara River Cave. We had seen evidence of hidden watery zones at Nodewood Cave 2, in the form of a crab low on the wall of an otherwise dry cave, (said crab then scuttling down into a fissure), and this new cave, (named Nodewood Rising by myself), appears to be an overflow resurgence active only when rains are heavy. Its location at no great distance from the Niagara River, between Niagara River Cave and Nodewood 2, suggests that there is a large network of small passages and fissured rock underlying the entire route. The phreatic zone rises and falls seasonally, but as evidenced by the two pumphouses in the area, and the sesarma verleyi at Nodewood 2, it never dries up completely.

After taking a GPS position, (six satellites, WAAS), we carried on to Niagara River Cave.
