Avenc del Puig de Marc

The general structure of the pit consists of displaced joints with large block falls. This causes several overlapping levels, which constitute different floors in the same plan projection. Therefore numerous “pseudogalleries” and “pseudoshafts” have originated that complicate the cavity extraordinarily.

At the mouth a ramp begins, at the end of which a 12 metre shaft starts. At its base is the main gallery which, following it towards the SE, has a new shaft that descends 16 metres more, but this sector remains obstructed a few metres on at the -31 level.

Again at the base of the entrance shaft and towards the NW there is a ramp that reaches a narrow joint that leads to a lower level. A room covered in guano follows that communicates, climbing over some blocks, with the Sala del Pou de 20. Following the main gallery we find a 5 metre shaft that also communicates with the previous room and, on the other hand, also communicates with the upper part of the so-called Sala de la Verge, which can also be reached via the Pou de 20 and which starts from the room that gives it its name.

A third way leads us to the Sala de la Verge following the main gallery between a chaos of blocks that at some points form considerable ledges. Once at the final point one must continue as if going back, but on a lower level, until reaching this large room, which has, at one of its ends, a small shaft that allows one to reach the -48 level.
