The entrance is in a deep shakehole on level ground near the top of Beralta. A single shaft with a small amount of passage at the bottom.
A re-exploration and full survey was carried out in the summer of 2003.
The hole is a collapse into an old passage and the ligher level must be cut off in both directions due to the slope of the hill.
A slide down the entrance slope lands on a flat floor with a choked cave to the south west and a slope to the main pitch to the north east. Over the pitch is the continuation of the cave which has not been entered but which must soon be cut off by the hill slope.
A traverse to the right (south) down a boulder slope for 6m meets 2 bolts (nuts in place) for a 12m pitch to a big boulder and ledge: the rope is hung on the right to avoid any rock falls.
The next pitch is a free 25m shaft behind a flake that gives protection from rocks above.
The small passage that takes water at the bottom is full of boulders with no gaps of any depth. An inlet rift was surveyed for some 20m to where it became too tight. This has an inward draught in the summer; capping would be a long job.
