Description

Morphology

a pretty developed entrance opens onto a fossil gallery. To the right, the downstream end is entirely blocked by sediments after 2 metres. To the left, during low-water periods, one can pass through a small sump that continues as a small gallery whose ceiling is sculpted with domes. After 13 metres one passes beneath entrance n°2, which allows permanent access to the continuation. The latter, cleared of obstructions over several metres, has been explored for about twenty metres.
