Avenc del Marge del Moro

A triangular opening 1'20x0'70 metres leads to a short descending gallery where a 17'6-metre pit begins, placing us on a sloping base that leads us to a blind pit of 6'3 metres. At the start of the 17'6 m pit, by means of a traverse, we descend a pit that places us on the other side of the blind pit, where we find a stepped pit of 12 metres that allows us to reach a small chamber at -35 metres formed by a crossing of fissures. From the small chamber, in addition to some small continuations, two galleries open, one oriented to the south of just over 6 metres and the other ascending and oriented to the south-east; after a few metres one must continue along a vertical squeeze of about 6 metres that gives rise to the terminal gallery, at the end of which 10 metres can be climbed up until it becomes impenetrable.
