A 0.4m wide and 0.5m high entrance leads into a meander 1x4m that, after 6m, became too narrow. In 2013, this was passed at roof level and leads onto a p6 from a column (use stals for rebelay to get 3m back, where the meander is wide enough). A drop back into the meander continues for another 6m where flowstone made it too narrow, leaving only a hole of 10x30cm. The hole was enlarged in 2013 and also at Easter 2014 when access was gained to the whole cave at the lower level. The cave draughted in.

After opening up the squeezes the explorers stopped in open passage, about 90m in. During the following trip, the squeezes were further dug out to allow the widest member of the team in, but the passage closed down 5m further on. The second squeeze is a tight upward manouvre leading to a short climb down into a 4 - 5m high rift, which is mainly comfortable walking size. This enters a chamber on the left with a hands-and-knees phreatic passage exiting straight ahead. The passage soon closes down at small holes and mud, with no sign of a draught on a reasonably warm day. Wide and deep scratch marks appear in the final mud wall.
