A boulder was removed from the entrance to reveal a 15m pitch. This drops into a chamber with a wide passage and calcite slope on the right and a dry streamway on the left. This was followed downhill to a bowl-shaped chamber where water soaks away. Upstream, it becomes necessary to stoop and the passage divides into a series of inlets.
From the bowl, a climb up a shale slope leads to an inlet which turns right and becomes tight. A small chamber can be crawled into at the top of the bowl.
