The entrance lies in a small depression with an obvious tree. The draughting head of the pitch is a chiselled and enlarged slot in a limestone face. The 25m drop lands on a rubble slope and the draught is lost.

A number of trips during 1999 enlarged the entrance and bolted across about 6m below the head of the pitch to an ascending calcite slope that ends in a draughting boulder choke in which one block prevents further progress. The choke appears to be immediately under the entrance of Hidden Hole (0458).
