A low crawl lies under a small scar back from the building. The is a 20m wide bedding filled with sand, mud and calcite flows. To the far left, through a stal grill, there is a small choked pit. The middle route has been dug to where 10m of the same diggable material can be seen. The best point to dig may be down to the right hand side. Draughted in at Easter but no draught was detected in the summer.
The cave was dug further and surveyed in 2001 with much more digging required over stal and mud layers.
