Located at the crossing of several joints between which the water of the temporary torrent has flowed and which have gradually widened until joining. The entrances are opened by epigean degradation.

Speleothems

Abundant reconstruction process.

Progression

Two small entrances separated by a rock bridge allow an easy descent without any equipment down to 4.5 metres, where the pit ends, choked by blocks.

History

First explored during the 1924 campaign by Rafael Amat i Carreras and his companions, after a second visit to the avenc de Sant Roc on 9 March 1924.

During the GES – CMB campaign in the serra de la Guàrdia (1950s) they find out that the pit is also known as del Tabac, alluding to having been used as a hiding place by tobacco smugglers.
