Updated 18th April 1999; 9th November 2003

The site is a complex of 4 shakeholes; the upper entrance is a grassy slope down to the head of a 6m pitch which lands on a muddy ledge. In the second shakehole, an 8m pitch lands on a large flake where the muddy boulder slope is visible. The 5m continuation down passes the boulder slope and becomes the original second rift pitch of 25m with a loose ledge halfway down. An area of collapse can be climbed down through to a 5m pitch which lands in a choked chamber. The whole pot is rather loose and muddy.
