A 4 x 1 metre entrance leads into a 9 metre deep shaft; after a narrow passage and by means of a step and a ramp, the descent continues to the – 14 level. Another shaft of 13 metres follows, with a totally aerial descent; at its bottom, a ramp 10 metres long and 5 metres in drop reaches the deepest level. From here, one can still climb up to another ramp that leads to an upper level created by fallen blocks that obstruct the joint. On the opposite wall and almost at the height of the start of the last shaft, there is a window through which one enters a gallery that remains closed a little more than 10 metres from its start.

Cavity structured along a joint with a direction of N12O-S12E.
