On the south side of a closed depression, 80m to the west of site 499, is a sandstone outcrop. The main depression has no prospect but on the south is a line of collapse and sinks at a limestone-sandstone boundary.
The second collapse from the west is 3m climb down to a small cave which heads west and has a draught but becomes too low after 10m.
