The entrance doline lies in the middle of a thicket of brambles, invisible from outside; a small path leads to it. a short earth slope leads to a small earthy step. The entrance (1 m x 0.5 m) first gives onto a narrow vertical opening leading into the entrance shaft. At first not very wide (0.7 m x 1.2 m), it widens progressively to a first ledge followed by a second, more comfortable one. Below lies the widest part of the cavity. a lateral calcite flow, together with a parallel shaft that widens the whole, has comfortable dimensions (4 m x 5 m). At the bottom, a pinched, hairpin-shaped stretch of passage leads to the edge of 3 shafts in succession, the arrival being in a pool of water and clay. There begins a narrow, inclined fissure with a clay flow, where there are a few possibilities of continuation given significant digging work.

At first, exploration had been carried out by belaying on whatever was available, but the rigging was very dangerous. We re-rigged the whole cavity with sealed bolts. One simply needs to bring one's hangers.
