At the top of a green depression under a large, open amphitheatre. The entrance is a draughting hole below a smooth undercut. The site has been excavated and a body sized hole drops down through loose and potentially dangerous boulders to a boulder slope and chamber. At the back, a bedding plane has been dug, but the draught emerges from the floor of boulders. To excavate here will require shoring in order to hold back boulders at their angle of rest.
The site was surveyed in October 2007.
