Various entrances in a collapse which were partly investigated in August 2018.
At the base of the collapsed sinkhole there's an obvious square entrance into a small chamber with a sandy floor. On the left is a man-made wall - perhaps a previous farmer used it as a cold store. Ahead, in natural rock, is a 6m long passage containing a small stream that appears to close down too tight. To the right is a 4.5m extension to the chamber. Both not explored fully. Water from the stream was seen cascading from the passage into a small pool of water near the entrance then overflowing and sinking into a boulder choke in the floor.
A possible high-level entrance was not explored.
