An interesting, strongly draughting hole above the stream bed.
The excavated entrance descends vertically down a rift that is tight in places to a 6m pitch and a further short climb down. A horizontal tube, The Blowhole, leads into a small chamber with a boulder slope opposite. The way on is up the boulders on the left and through a slot. The passage soon opens up in a larger chamber, Yerma Hall, where the right hand side consists of large boulders with spaces above them. A crawl on the left becomes too low. The passage continues through a short crawl to a 2m climb down. Here narrow draughting rifts have been noted on the left, but may not have been explored. A further side-passage on the left is slope upwards to a high cross rift.
The main passage turns right and enters a rift; it is necessary to climb down the first 3m, and then traverse across to a chimney upwards. A short crawl breaks into larger passage at the marked Station 13. To the right the passage slopes up through boulders into a chamber, The House of Bernarda Alba. At its western end some black spaces can be seen between the boulders in the roof.
In the opposite direction the passage becomes smaller, crosses beneath the entrance passage and after some thrutching reaches a small, steeply descending chamber.
Back at Station 13, to the left, the way on is through another narrow rift. The passage becomes a tube in solid rock, Blood Wedding Crawl, where the draught gets stronger again. The survey ends at a potential dig, with a crawl in the floor and a stack of boulders fallen in from above.
