Caratteristiche

Località

At present, the most practical approach is to reach the end of the Brasil passage; from there, to the west, the end of the Serral del Suro ridge can be seen. The cavity is located 165 metres away to the north-west with a drop of about 20 metres. Very approximate coordinates.

Descrizione

Morfologia

It opens to the exterior through a large fracture 28 metres long and between 1 and 2 metres wide; in addition, there is a drop of 7 metres between the upper and lower lips. The fracture is divided into several sectors due to various collapses. At the point where the fracture is most penetrable, it takes the form of a shaft 8 metres deep that allows reaching -15 metres from the upper level. The fracture can be accessed from various points not connected to one another. The part farthest along the fracture is where the -17 metres depth is reached.

Storia

The first reference to this cavity is the one provided by Jordi Lloret and Jaume Ametller in the mid-70s, when they were members of GEFOMA at that time.
