Tyre Stream Cave

May 11, 2005

Team: Stewart, Conolley, Slack

Notes: RS Stewart

The day started with a search for Dalby's Stream Cave, near Tyre. Paul Bailey, long-time resident and farmer of the district, assisted by showing us the two sites that he knew of near where Dalby's is listed to be. Neither were a proper match, with the first not revealing the passage that should have been present (although this might have been underwater because of the time of year), and the second obviously a previously unlisted cave. This second cave, named Tyre Stream Cave by us, is a stream passage, active during our visit, taking water, and extending for at least 80 metres. It does not resemble Dalby's, or any other cave listed in JU for the district. Exploration remained incomplete due to flood-risk, but a return visit will be made in the future for further exploration, and survey.

The cave is formed in strongly-bedded rock, at the junction of the Yellow Limestone, and White Limestone. Development is complex with the flow entering from beyond the entrance, and sinking to a lower level after some tens of metres (this was accompanied by an interesting siphoning sound first heard well back from the sink.

The passage carried on without becoming smaller past my farpoint, which was apx. 80m. The trend of the passage suggests that the flow might be to the Coco River, although this is shown as being on the other side of the watershed, to the south.

This new cave has been named by us as Tyre Stream Cave. It is much more interesting in extent and potential than the previously listed sites of the area, and is one or our best discoveries during the PiP Project.

S. verleyi were present, with a bluish colour variation. A leg was collected.

E. cundalli were using the passage near the entrance, as were Buffo marinus. No N. farri, Araneae, etc, were present.

We're listing this site with a medium vulnerability due the potential for siltation if farming, especially of yams, were to take place on the hills surround the cockpit. Note that the cave is within the Forestry Reserve borders.
