Aven du Téléphone

The entrance, of large volume, is located at the bottom of a collapse. The P15 is at first narrow, then its dimensions increase afterwards. The base of the shaft forms a muddy chamber. The diaclase est narrow, and the elbow passage is narrow.

At the base of the 10-metre shaft the S1 sump develops.

A passage under a block gives access to the first inclined plane. At the end of it, a 4-metre step leads to the second inclined plane, which is muddier. At its extremity, a P15 develops. At mid-height, a fractioning offers itself on an enormous wedged block. At the base of the shaft, a skylight allows easy entry into the following step. At the bottom of this, a passage cleared at the start gives access to a narrow diaclase est; it should not be descended but rather continued in its extension. A narrow elbow passage gives access to a 10-metre shaft.

Geology: Turonian rudist limestones.
