A locked gate leads down a fixed ladder in a large tube for 4m and continues through a series of free climbable scaffolded pitches where a low crawl leads to a 12m free hanging pitch. Beyond this the passage varies from walking to stooping and then long sections of strenuous narrow rifts lead to a low continuation leading to a sump and a series of low passages, chambers and a rift lead to the impressive Yorkshire Pot with no way on.

Alternate Names: None recorded.

Notes: The end dry passage stops at a section where progress is barred by formations. This has been investigated and there is no passable way on. Please do not go beyond the tape.
