Description
Morphology
The cave opens in Jurassic limestones, a few metres from the Jurassic-Cretaceous contact. The entrance is a fissure set on a joint, 9x1 m, which forms the entrance to a 22 m pit. At 11 metres depth a short crawl leads to the second pit, 28 m deep, closed at the bottom by landslide debris. The cave is 42 metres deep in total. The cross-section of this second pit is characteristic, perhaps formed by a waterfall set on a main joint and on other minor fractures.
Hydrology
The terrain upstream, made up of Cretaceous limestones, is relatively little absorbent, and a fair amount of deciduous vegetation grows on it. The Jurassic limestones are instead much more absorbent; in them there is only herbaceous vegetation and numerous dolines are present, all contained in a small dry valley.
Progression
Among these dolines the cave opens. The bottom of the first pit is permanently occupied by snow. A faint light reaches the bottom of the cave.
