Description

Morphology

A short slope places us in a pit 4 metres deep; the base is full of stones.

History

Discovered and explored by the EIE de la Penya Cultural Barcelonesa on 21 December 1969. Due to erroneous information, for years it was considered lost; the search carried out recently by Jaume Julià, one of the members who took part in the first exploration, has been essential for its rediscovery.
