This site lies on the side of the "Hidden Valley" south of the main Cobadal depressions. A few metres of walk-in passage reaches the top of a deep pitch (20 - 25m) at the near end of a rift about 10m long, with water showering out of the roof. There is a good echo from rocks dropped down. On a visit to bottom the hole, it was found too wet to descend.
The site was explored in August 2013. A narrow, 3m wide entrance leads top a vertical rift, 9m across at this point. A descent of 19m ends on a floor covered in rusty tin cans. The floor slopes down a further 2m. At 6m down the pitch, an inlet passage can be seen at the far side of the rift. At the bottom, the rift narrows to 5m long but is now 3m wide. There is no prospect of further progress.
