Description

Morphology

A triangular opening gives way to a 10-metre ramp that ends in a -3-metre drop; the gallery continues descending on a slope for some 20 metres while gradually widening, and a new -4-metre drop places one at the bottom of the cavity.

History

Known to the local people, it was explored between 6 and 7 June 1965 by the SIRE–UEC of Igualada. The cavity was given the name of the person from the village who informed them of the existence of the cavity.
