In depression adjacent to T68.


Small draughting hole at farthest point from track. Entrance


7m pitch to squeeze and 3m climb into small chamber. A rift leads off in right hand corner.  A strong draught is in evidence.
The floor of the rift has been dug out, to allow a tight 3m drop into a rift. The rift widens over a false floor, which has been dug downwards for approx. 1m to reveal a P60.  The pitch is extremely tight at the top and larger cavers will struggle to pass.
The p60 widens and drops into a large chamber.  There is no apparent way on and the draught has been lost.
