Avenc Nº1 de Requí

Lower entrance: going up the scree we reach the lower mouth that opens at the foot of the rock of the cliff with the appearance of a fissure with a roof. On the right there is a crawl that leads out a few metres further on in the form of a ledge over the inner crevice, and upwards a light opening can be glimpsed that must correspond to an upper entrance.

Upwards the gallery, after climbing a small drop with some branches, closes by an accumulation of blocks. In a descending direction the "room" divides into two parallel galleries, in part superimposed, that end by narrowness and wedged blocks by which we reach the level of -19 metres from the initial or lower mouth (level -42 of the whole cavity).

Upper entrance: we descend by the first upper mouth located, which is situated near the vertical of the lower mouth. Later a second mouth was found a couple of metres higher and some ten away which we consider level 0 and which comes out in the very middle of the upper gallery.

The upper gallery is structured on the same fracture and at 13 metres the 12-metre chimney appears that leads to the upper mouth. In total this gallery has a length of 40 metres, and a slightly longer route through some double passage and small ramifications. It ends by a narrowness of the crevice that at its top through a small hole shows the outside light.

Descending the shaft, now at level -2, a shaft-crevice of 31 metres of vertical opens. At -11 of descent a pendulum places us in the upper gallery. If we continue descending 11 metres recovering the pendulum and passing through a wedged block we reach the head of the P9 of the lower gallery. Thanks to the previous rigging and the double-rope installations, we make the traverse between entrances recovering all the material and exiting by the current level -22 metres.
