Description

Morphology

After an entrance pit of about 18 metres, one lands in a fine chamber. On one side, an ascending joint gallery leads to a well-decorated alcove. On the other side, the joint pinches after a few metres. At the bottom of the chamber, passing a dried-up calcite gour, one reaches the bottom of a heavily decorated chimney.
