Cave passage description (Nigel Dibben, August 2015)
This is a fossil cave with no draught.
The cave contains a meandering walking-size passage approx 80m long with a distinct left and right bend in the centre. The floor is sandy soil mixed with animal faeces and bones of sheep and goats etc. At the left bend, a short passage goes straight ahead with possible "bears' nests" in the floor and definite bear claw marks on a clay wall to the left at the end. The passage ends with a rise to a higher level which is too small but shows phreatic features in the roof. After the left bend, a short branch goes back towards the entrance but closes down. The passage bends right through a sandy chamber to a constriction between stal. After the constriction, there is a small chamber with flowstone walls ending in another tight passage which is not passable. There is a chimney above the entrance chamber.
Notable features include bear marks on walls and possibly floor; animal remains and fungi on the floor; the phreatic roof and stal in the final chamber reached.
