Caratteristiche

Località

From the coll d'Eres we will follow the path of the Mola; on reaching the first crossroads we will follow the path on the left in the direction of the area of les Fogueroses. A little further on we find a new crossroads and we will follow the path on the left.

This well-marked path leads to a viewpoint that lies in front of the rock known as the Roca de l'Equilibri or Forat de la Senyora; the cova Gran is located just below.

A few metres before reaching this viewpoint, however, the marked path continues on the left, descending through a gully where shortly we find a rock that divides the path in two in the form of a crevice, it being possible to descend on either side. At this very point, before descending this passage, on the right and somewhat raised above the ground, we find the small entrance “C” where we find a good draught of air.

We continue descending the path and, just past the passage divided by the aforementioned rock, on the right we find a tree right next to the rocky base; here we begin a short and easy climb in the direction of the hole known as the roca de l'Equilibri, or forat de la Senyora. From here, on our right the entrance “B” or Gruta Verda can already be seen; it is necessary to descend a few metres from this position and climb the gully that leads to the entrance.

From this point of the roca de l'Equilibri we will continue along the path, which descends a few metres to the base of the cliff; we will follow this and in a few metres we reach the head of a gully where we find the entrance “A” of the cova Gran de les Fogueroses.

Descrizione

Morfologia

The entrance gallery (entrance A) is about 9 metres high and follows a joint in a SW direction. At 8 metres a short gallery of 8.5 metres opens on the right, communicating through small holes with the so-called Gruta Verda (entrance B) of 16 metres in length, but the passage is impassable.

The entrance gallery continues 6 metres more, until finding some large boulders of clastic origin (section 3). From this point two galleries start, one towards the NNW and the other towards the S. The first, one metre wide and of considerable height (4.5 m), continues some 12 metres. The other, narrower (0.60 m) and 8.5 metres long, is the one that presents the most developed lithogenic process (section 12), but in an evident state of decalcification, since the infiltrations following the joint are almost nil at present.

To continue the exploration it is necessary to climb the aforementioned boulders up to a platform that follows the same direction as the entrance gallery (section 3). Again we have two paths to follow: on the right, two galleries that after 3 metres join forming a low laminator (section 11) that can be followed 10 metres more until giving through a reduced passage (section 13) to the exterior (entrance C).

On the left we have the longest gallery and the one that leads us to the final point of the cavity. It is of reduced dimensions, especially in the final part (section 9), and it is necessary to crawl until it becomes impracticable.

Storia

The first speleological news of the cavity is that of the chance discovery on 2 July 1972 by Jaume Rovira and Josep Graells, members of the Espeleo Club Sabadell. The following Sunday, they themselves with colleagues from the club, carry out the exploration.

The finding of a shoe nail (from an iron sole) and a pile of rocks stacked with signs of having made fire, gave them to understand that they were not the first to visit the cave. It had probably served as a refuge during the war.

A year later a very narrow passage was forced and it was possible to exit to the exterior through one of the final galleries (entrance C). Later, on 16 August 1975, J. Anglarill, J. Renom and Ll. Canet carried out the total survey.

Despite being a little-visited cavity, it seems that it was already known around the 1960s, especially by the climbers who at that time frequently visited the area. On the internet quite a lot of information can be found.
