Updated 11th October 2007
A low entrance under a sandstone roof which takes a small stream in wet weather. A crawl to left passes a squeeze at a dropped block to reach a climb down of 5.7m.
At the foot, a low crawl back under the climb leads to a gradually enlarging passage with a series of bends and small climbs down to a junction. To the left is too tight, straight ahead ends shortly in an unclimbed aven, whilst to the right continues round a further bend to the start of a traverse along a narrow rift. After 10m this gets too tight for further progress with the floor now some 3m below the traverse level. It is possible to communicate from this series up to the entrance crawl.
The other direction at the foot of the 5.7m climb is walking size to where the rift closes. Just back from here in the left wall a hammered out hole leads through to a parallel passage. To the left is a lowering sand-floored crawl to a complete choke, whilst to the right is a comfortable crawl to a junction. To the left closes to a complete choke almost immediately, whilst straight ahead can be followed as a flat out crawl for 12m to a choke. The passage to the right is walking size, with a floor of thixotropic mud, and has a number of side passages leading to blind avens. A narrow slot in the left wall near the junction is too tight currently but has a good echo.
