A 50m x 30m open hole which has been explored down at the northeast corner to a depth of 15m. There is a small dig at the base with little prospect. This large collapse feature shows that there must be development under the area. A possible cave on the north wall was examined but proved to be a choked series of rifts formed by slipped sheets of wall rock.
The GPS reading is taken on the north lip in line with the centre of the N-S rift.
