This shaft started off as a fist-sized, draughting hole and was excavated to a 5m climb down with the draught coming out of a hole to the south east. (This was last excavated in the summer 2009).
In the opposite direction, the passage slopes down into a decorated chamber then levels out to the head of a 7m pitch. At the base a steep calcite slope drops to a pool and calcited end.
