A prominent entrance, slightly smaller than site 641. A 7m crawl leads to a inwardly-draughting squeeze over a rift. Beyond the squeeze is a pit, maybe 4m deep floor to roof. The far side of the pit is 2.8m from the squeeze. A very low bedding can be seen to continue at roof level for at least 4m beyond the pit.
