Description

Morphology

The entrance depression is open at one end. The original fissure bifurcates at the bottom, with little passage on either side, remaining blocked by boulders.

Progression

The entrance depression, open at one end, allows an easy descent following the original fissure until reaching a small step, which places us at the bottom of the fissure.

History

Discovered from the information provided by J.R. Segura while he was carrying out the Guia Excursionista del Montsec d'Ares; members of the Grup Espeleològic de Lleida explore it on 28 March 2008.
