Avenc del Mussol

A typical collapse pothole with a general NE-SW orientation, blocked by boulders in some sectors. It is 48 m deep and about 115 m long.

Entering through the so-called no. 1, you must descend the entrance pitch, 16 metres deep, and continue among boulders until the pothole is cut by a small 6-metre pitch which, once passed, leads down a steep slope to a depth of 26 metres. Here it seems to be closed, but among the boulders you can continue descending, by means of a 5-metre drop and then another 16-metre pitch, quite narrow and with a strong draught. The fissure continues, but its narrowness makes progress impossible.

Back at the base of the 5-metre drop, above it you can see a kind of, let's say, window, which connects with the central zone of the descending ramp from entrance no. 2. From this junction point the ramp gains inclination until reaching a small 4-metre pitch which, once descended, leads to a narrow fissure up to another small pitch, also 4 metres, where the fissure continues in depth, but the narrowness makes passage impossible.
