Descrizione
Morfologia
It is a small cavity structured along intersecting joints; it has two small entrances, the one situated further to the NW being the larger (currently 0.70X0.40 m). The smaller entrance is only 0.35X0.40 m.
We enter through the large entrance by means of an R-1.50 metres, where we find a gallery about 0.40 metres wide and 1.40 metres long in a Northerly direction; the cavity appears to continue, but some blocks prevent further progress.
From below the entrance entrance, and in direction S, we find a descending passage where we descend two consecutive R-1 metre. At the second, and slightly elevated and to the side, we find a small step that is the base of the shaft coming from the small entrance.
At the base of the last R-1 mentioned above we reach the first perpendicular joint. To the right it ends at 1 m distance. The new gallery is 1.20 metres high by 0.50 metres wide; continuing to the left one descends a steep slope through a narrow passage. At 1.50 metres we find another joint that crosses. At this point we can hardly move, as the dimensions of the gallery have decreased considerably. Here is the point of maximum penetration in the cavity, -6 m.
Opposite, the gallery ends in little more than a metre. To the left a new joint ends immediately; the cavity should have its logical continuation along the right-hand branch where a current of cool air is perceptible. Unfortunately it is a fissure 0.17 m wide, totally impenetrable; a shot with the “disto” gives -4 m, as it is a small shaft.
Storia
The first exploration was carried out in 1967 by the GES del CM Barcelonès. Joan Borràs (GES) returned in May 1972 to do the survey. In May 2014 the GE Badalona carried out a survey revision.
