Description

Morphology

The cavity presents two entrances to the exterior, although the larger one is not visible because it is covered with trunks and branches.

This large entrance gives way to the central part of a 20-metre fissure over a pile of debris with a steep slope towards both sides.

History

Explored by the ACEM in 1969.
