Località

Taking the road from Alcover to Capafonts (TV 7041), before reaching Mont-ral and a few metres before reaching Km. 10, an initially asphalted track branches off, crossing the Pla de les Perdius. We will always continue straight ahead, ignoring the forks, until the track ends in a widening of it in the middle of the forest, on the ridge of the serra d'en Clarà. From this point and in a N direction a path leads us to the avenc del Cabirol, after passing the point where it branches off towards the avenc de la Carbonera, and a few metres before reaching the avenc del Cabirol, on the right, a path leads us to a clearing in the middle of the forest, it is an old charcoal kiln, on the right-hand side as we arrive, we find a cairn that indicates the path to follow, we will soon reach the avenc NR-7 which is on the right of the path. This pit has two more entrances, one next to the main entrance, and the other is on the other side of the path, but both are impassable unless they are cleared.

Descrizione

Morfologia

A narrow entrance 0.42X0.58 metres gives access to a short gallery that leads us to a 1.50-metre drop, the base is formed by a small ledge that opens into an inclined and broken-down joint along which we will advance secured in a NW direction, where abundant lithogenic formation can be seen and it can be observed that the joint is wider and gains verticality. From this point we will descend a sinuous but wide 20-metre pit. The base is located at elevation -31 m, towards the SE we find two continuations, one on a steep ascending ramp that climbs the joint up to elevation -24 m, while the other continuation is a narrow passage that narrows until it becomes impenetrable, but through which there is a notable air circulation. On the NW side, a small drop formed by sediments from the exterior must be climbed, here we find a pit about 7 metres deep followed by a descending ramp that leads us to the final point. The joint still continues in the form of a meander, but impassable due to its narrowness, the final elevation is at -38.50 metres.

Storia

From the little data available, it seems that it was located and explored by the AAEET de Valls in 1998, during the prospections carried out in this area. We do not know the meaning of the initials NR with which some of the cavities in this sector were named.
