Avencs Nº1 I 2 del Pas dels Llops

Pits no. 1 and 2 are connected to each other. Pit no. 2 has a small entrance that narrows within a few metres, with an air current noticeable; from this point a -40-metre shaft begins that leads to the bottom of the cavity, and at this point it can be followed along the base of the fissure for some 30 metres. Along the fissure we find blocks wedged in the narrow walls, which form a kind of unstable galleries. One of these galleries is found in the upper part of the -40-metre shaft, forming a very irregular gallery, with steps between blocks, and which ends some 6 metres above the base of the shaft of pit no. 1. Pit no. 1 has two small entrance openings where a small -5-metre shaft places us in a short gallery that connects with a narrow shaft -20 metres deep.
