Cavity developed in conglomerate, exposed to rockfall, whose cleared low entrance leads to a chamber with a pool and to several branches adorned with speleothems.
Description
Morphology
The low entrance was cleared of the fill that had accumulated to facilitate entry into the cavity. One emerges into a chamber whose floor is occupied by a pool. This chamber has two branches; the left one stops after a few metres. The right one leads to a mound of earth. From there, three branches present themselves: the first, the smallest, is obstructed; the other two run for a few metres.
Speleothems
The other two branches run for a few metres and allow one to see pretty speleothems.
Hydrology
The floor of the chamber is occupied by a pool whose level varies from 20 to 50 cm in depth. We emptied it with a 10 m garden hose.
Progression
One must climb to the left to reach a new chamber and the top of the mound.
Other details
The cave develops in conglomerate, which exposes visitors to rockfall.
