A draughting, walk-in hole to an excavated squeeze through to a ladder pitch to a bouldery floor. Rocks were thought to drop another 15m into a chamber with a good echo.
After enlarging the head of the drop in 2003, the final pitch was found to be only 10m, landing on a flat 2x7m floor. A slight draught was detected from a small passage below the head of the pitch.
