Location

At the highest part of the village of la Riba and along the TV-7044 road heading towards Farena, take the path on the right that leads towards the Puig de Marc, leaving the characteristic hill of the Castell del Dalmau on our right. When you reach the first flat area formed by the Puig de Marc, move westwards to look for a cliff (Pena del Puig) that rises above the valley of the Brugent river, and a few metres below the upper cliff and beside a gully, the cavity is found.

Approximate coordinates and difficult to locate.

Description

Morphology

A collapse fissure that reaches 48 m in depth. Within the large outer fissure, a small opening between blocks gives access to a first shaft 14 metres deep. At its base, the fracture that originates the entire cavity continues towards the W, becoming impassable after a few metres. In the opposite direction there are a series of steps between the blocks that lead to some narrow galleries that close after a few metres of passage, until reaching the lowest one, where at its lowest point the maximum depth level is reached (-48).

History

Discovered and explored by members of GERS – AE Muntanya (Barcelona) around the year 1975.
