Updated 17th October 2004; 7th October 2006

A depression at the end of a track (full of vegetation in 2006) has a 4m climb down over soil and rubble at the western end (a ladder improves the experience) to a tall, 10m long chamber with old calcite wall flows and sloping floor. A rift at the end can be climbed up for 12m. Digs in the floor have been attacked but with no way on.
