A 20-metre-deep pit in Sales de Llierca, explored in 1973 by the GE Olot.

Characteristics

Location

Between the Coll de Faja and the Coll de les Bassetes, beside the Pas del Treu, more specifically to the NW of the Pla de Freixenet. Around the entrance there are other collapses. Three or four old, bushy pines beside a half-lost path serve as a guide to find it. The pit has a small mouth, marked with red paint and practically covered by a large stone (data from 1973). Approximate coordinates without much precision.

Description

Morphology

At the bottom of the entrance shaft, 12 metres deep, a slightly descending gallery 15 metres long begins towards the W, which after a narrow passage communicates with a 7-metre chimney. At its upper part one reaches the main joint of the cavity, almost parallel to that of the entrance shaft, tall and narrow and which towards the E has about 29 metres of route in an ascending direction. From the fork and in the opposite direction, that is, towards the W, the joint continues some 12 metres more. To continue one must climb it about 5 metres and reach a ledge, from where on the left there is an 8-metre pit and on the right another, which divided into two sections reaches a depth of -20 metres with respect to the entrance mouth.

History

The first exploration of which we have record was carried out in 1973 by the GE Olot.
