   The GPS reading, taken at Easter 2006, seems to place the hole rather a long way from the original coordinates (VP52150020).
   An obvious 2m high entrance leads to 6m of passage which ends, too tight, with no draught. An alternative viewpoint, noted in summer 2002, is that the cave draughts out strongly and looks diggable.
   The cave was excavated in August 2016. The draughting right hand wall was dug out. The route drops down steeply onto 3 benches with a blocked chute at the base that would require a lot of digging.
