Enaso VN50469646 Alt. 273m  Length 200m Depth 33m

A 22.5m drop off the western side of the pot lands on boulders. A short crawl on the right hand side leads to a large (25 x 35m) chamber with a well decorated, low passage leading off for approximately 70m and choked at the end. A junction half way along this passage leads to a well decorated chamber with empty gour pools and stal ending at a flowstone wall. A slot in the floor chokes after 4m.

To the left of the pitch chamber, a route leads down a loose boulder slope to a 25 x 25m chamber. A calcited skeleton of a possible bear with 4cm long incisors and a 35 x 15cm skull lies in the centre of this chamber.
