Avenc de la Barcina

The cavity begins with a 24 metre pit, not very wide, down to a small ledge situated above the second pit of 19 metres, which leads to a chamber of notable dimensions. At 3 metres from the start of this second vertical, and thanks to a small pendulum, a short side gallery can be reached which, with an 8 metre drop and a 13 metre pit, also brings one to the aforementioned chamber.

From this chamber two possibilities of continuation present themselves: a 28 metre pit, on the N wall of the chamber, and a small 8 metre pit on the S side; descending the latter brings one into a small chamber from which several galleries emerge that connect with the P.28. Following the most evident one, after passing over a pit that opens in the floor of the chamber, one reaches a ledge 11 metres above the base of the N pit of the chamber. From here there are also two options to continue: descend a 4 metre drop and follow a narrow, descending fissure that opens on the left; or, from the base of the P-28, climb a 3 metre drop and further on descend a P.8 that leaves one past the fissure of the other route. Once here, with a short slightly descending gallery, we reach a small chamber where a 9 metre drop opens, downclimbable from the small chamber but, some galleries without much interest emerge. Having descended this 9 metre drop we find ourselves at the beginning of the final fissure of the cavity. The first 18 metres are wide enough to allow comfortable progress without a rope, afterwards however, it becomes extremely narrow (level – 110) and although it can be descended without a rope, this can be useful when ascending; at the end it becomes a little wider and the maximum depth of the cavity is reached at – 142 metres with respect to the mouth.
