Shaft (647) marked DCC1 and 509; cave marked DCC2. Cave entrance in cliff face and requires a 5m roped descent from above although this may not be necessary. The shaft alternative is 8m deep.

From the cave entrance, the passage slopes down and becomes low before reaching the head of a chamber, down on the left. The floor of the chamber consists of pools and slippery calcite. The way on is across the top of the chamber on the right, via a small passage which slopes into a massive 40 x 30m chamber. The boulder slope on the right leads up to the base of the 8m shaft entrance (647). Another passage on the right ends at an undescended pit, but see ref. L84.
