Length 15m Depth 5m
Area position


Updated 12th May 2018

   This site lies above the (wet weather) sink. A 2m wide rift drops for 3.5m where a step down to the east meets the water which sinks. Possibilities for extension exist.

   There are a number of interesting holes in the vicinity. These are 4653, 4656. The current grid reference above is a guesstimate based on a GPS reading (30T 0448789 4801852) taken halfway between 4655 and 4656 and a sketch of the relative positions of the 4 sites.

  The site was linked to 4655 in April 2018, with no obvious way on.
