Descrizione

Morfologia

The entrance is Un effondrement (a collapse) of 15 x 10 m cluttered with blocks. The West gallery is Un grand décollement de strate (a large bedding-plane separation) with many lateral recesses; after 25 m, this spacious gallery ends at Un petit mur (a small wall) that must be climbed. Behind it is a rubble-filled chamber from which several crawls lead. One of these leads to -8 m, the lowest point of the cavity (small pool in rainy weather); continuing and passing between blocks, one can return to the chamber. Another crawl leads north and narrows at -6 m. The East gallery is reached by three passages east of the entrance; Un vestibule assez bas (a fairly low vestibule) continues as a low descent, then Un passage ébouleux (a rubble-filled passage) leads into a small earthy chamber at -5.2 m.

Idrologia

The lowest point of the cavity, at -8 m, has a small pool in rainy weather.

Progressione

One descends easily on the sides of the collapse. Heading south, one reaches the start of the West gallery, which goes in that direction. After 25 m, Un petit mur (a small wall) must be climbed. The north crawl, which narrows at -6 m, would be worth pursuing because the survey shows that nothing is known on that side.
