The entrance, in a wooded area, is a steep mud slope under a small rock face where a handline is a help. Tight for the first few metres, it quickly enlarges to walking size passing a stal grotto on the left. At the foot of the slope is a further group of stals in an alcove on the left, whilst a small passage on the right quickly ends in a choke only a metre from one of the side passages in Freedom Pot (site 2737).
The main way continues walking size, passing a climb to a short length of choked passage up to the left, to reach a traverse over a hole in the floor. This has been enlarged to allow access down it for 6m but more work is needed to reach the floor. A good outward draught was noted here in hot weather.
Beyond the traverse further walking leads up a slope to a mud choke. This has been dug for a short distance but looks as if it may swing round to the left to join the top of the pitch gained through an enlarged crawl up in the left wall a few metres back. Through the strongly draughting crawl the 8m pitch is too tight 5m down. There is a sound connection between this pitch and the hole under the traverse.
In the summer 2008, a breakthrough was made down a p9 to the streamway. This has been described as typical Yorkshire-type cave, ie rifts, small chambers, some stal and tight crawls, draughting well. Upstream and downstream total about 150m.
