Area position

   Described as "having the best draught in the area", the hole is something of a disappointment.

   The entrance lies in the base of a shakehole. A flat out slide under a large boulder leads down to a ledge overlooking a very steeply sloping drop of about 12m. The 2m wide rift is negotiated by bridging down to a fallen slab then sliding down to a rock ledge and a simple climb down into a chamber.
   There are three ways on from the chamber. To the left a short climb up leads to an excavated crawl into a low, 3m diameter, choked chamber. An extremely cold draught howls out of the sandstone choke at the end of the chamber. "There is little chance of 'poke and run' but a fresh pair of eyes may see otherwise." Back in the entrance chamber, a rift beneath the overhang leads to another view of the choke seen in the chamber to the left (no draught).
   Turning right from the chamber leads to a hands and knees crawl over a series of holes in the floor. The first hole was choked. An egg (hen's?) was on the left hand ledge. Further on, an excavtion beneath a large block found a small chamber with no draught. A further tight crawl with anastomoses arrives at the end of the cave. To the left a descending phreatic tube closes down. Ahead is a large, damp sandstone choke with very little promise.
   Below and to the right is the excavated entry to a 5m deep by 2m diameter chamber with clean-washed walls. An excavated squeeze down ends in cross rifts with a slight draught but no way on.

   "If you're passing, go and experience the the draught - very impressive."
