Esquerda Gran de Cantacorbs

Located beside the cliff, it appears as a large crevice with open-air and other underground sections. At one point a space opens between blocks about 20 metres long by 5 metres deep, which probably corresponds to the foot of the cliff in this sector.

We descend by the S end, where we must lower ourselves with a rope down a first vertical of 6 metres; a ramp follows and a new vertical of 5 metres and a last one of 4 metres that places us at the -15 m level. We pass beside a large window that gives onto the outside, descending down a new vertical of 8 metres to land at a point where a space opens between blocks about 20 metres long by 5 metres deep. Returning to the bottom of the large crevice, we bypass a large quantity of blocks and climb back up in a NW direction from where two galleries start. On the left we advance only 4 metres where the narrowness makes continuation unlikely, although following the same direction we would come out again at the outer cliff. Through the opening on the right we ascend among a small labyrinth of passages between blocks until we finally come out to the outside through a small opening that places us on a platform higher than the other end of the Esquerda Gran and at approximately the same height. That is, first almost in the open air we descended 15 metres deep and then, "underground", we climbed back up the 15 metres, coming out to the outside about 50 metres away, at coordinates X342222, Y: 4576944.
