Entrance 1 is a 3.5m slide down over a block to a 6 x 2m chamber with a vertical mud bank at the northern end. This leads to a high window and day light from the second entrance. Nearby is the second hole, 3m diameter, with a 5m pitch landing in a roughly circular chamber of boulders. The only way out is down through a window to below entrance 1.
