Description

Morphology

A small pit of just over 2 metres places us at two short descending ramps; one ends after a few metres and the other leads to a crawlway past a large block wedged at the start of a 6-metre pit that gives access to the main fracture, obstructed by a significant clastic process.

History

We do not know who carried out the first exploration of the cavity, although we think it must have been speleologists from Reus towards the end of the 1950s or the beginning of the 1960s.

The oldest reference we have is that of the exploration by the SIE – CEA in 1971.
