The obvious, excavated hole is at about the lowest point at this part of the valley and appears to take a stream in wet weather. A short climb down a loose wall meets a duck under to a tighter section that drops down a bed into a chamber. To the right, through a stoop, is a small aven with calcite and a choked area; straight ahead in the chamber, down slope leads to the head of the first pitch, p7. A 4m drop leads to the head of an 8m pitch. A 10m sloping drop ends at a 7m pitch that drops into a 10 - 12m diameter chamber with a couple of blind holes under boulders. A steep, scalloped, clean-washed rift drops down to a small, circular shaft that lands in an elongated chamber.

The main way out is a tight rift, quickly opening to a fossil streamway for about 12m to a mud sink and no possible way on. In the opposite direction is a narrow rift that becomes too tight about 6 or 7m. This did not look promising.

For SRT, a 60m rope, 10 hangers and 3 slings will tackle the pitches and climbs between them.
