   A flat out crawl under a rock face part way up the side of a depression leads to a drop into a standing height "chamber" almost immediately. Two holes off to the right choke, as does one to the left. Straight ahead is a slope up into a sideways crawl to formations blocking the way on towards a strong echo. There is a good draught coming out of the entrance.
   A couple more trips extended the hole to a reported 100m length and 30m depth. The site is complex and needs surveying.

   A visit in December 2018, "in our regular clothes" logged: A small pit in the floor of the entrance chamber appears to draught and appears to have had digging efforts in this area. The stal area previously photographed has already been broken through and appears to continue. Echo still apparent, but doesn’t go anywhere. Sound just reverberates in around you.
