Cova Nº1 dels Nerets

The cave is the penetrable underground part of the fissure that is hinted at outside, formed by an 80-metre-long gallery that, at the crossing point of two fissures, has suffered a collapse, the gallery continuing at its bottom on both sides. The entrance shaft ranges between 2 and 5 metres in width and has a depth of 10 metres, although it is almost occupied by large fallen blocks. On the E side we find the entrance portal of a gallery without important branches, which maintains an average width of 2 metres, connected with the outside at its central part by an impenetrable opening. At 34 metres from the entrance the gallery loses its horizontality, remaining closed after 20 metres in a room very close to the surface and located below the drainage platform, this point being one of those where the fissure is plugged with cement, to avoid lateral losses of the water current.

At the foot of the aforementioned step, the mouth of a 7-metre pit opens, interconnected with some intermediate galleries of reduced section. The lower part of this pit meets the middle zone of a lower gallery with a gentle slope towards the W and which ends up becoming impenetrable in both directions.

Again below the entrance shaft and continuing towards the W among the chaos of blocks, one can access a conduit, of much more reduced section and which can be followed for about 20 metres.

The cavities have been formed on a system of detachment fissures, parallel to the crag.

Noteworthy is a thin sheet of calcite that appears to divide the gallery into two superimposed levels in the final stretch.
