Updated 8th November 2000

Strongly draughting 10m pitch leads to a window to a 15m shaft. This drops into a tight rift. A 5m climb up at the bottom leads to a blind window. A small trench below the last pitch can be followed to a too tight rift. At the start of the trench is a narrow rift which drops into a small chamber with no outlet.

Part way down the first pitch a step off leads to a small chamber and a short, choked 5m pitch. The draught is lost.
