Descrizione

Morfologia

The entrance leads into a semi-fossil gallery intersected by a step and an old wet roof whose threshold has been broken. Ascending an 11-metre climb equipped with bars gives access to an active meander. The 11-metre climb is done on a calcite flow.

Idrologia

The active meander can be ascended to a sump that can empty during great drought.

Progressione

A beginner's cave up to the sump 900 metres from the entrance: opposed passages, small climbs… The 11-metre climb on a calcite flow is equipped (2023) and gives access to a junction of galleries: take the right-hand one; then to the Salle du Nœud where one also takes the right-hand Gallery which leads (with a little searching!) to the Galerie Bourgin. The continuation is on the right, by crossing a P15 on a rock bridge.
