Descrizione
Morfologia
An entrance of 1X1.17 metres, easily down-climbable in two sections of r-1.60 and r-1.40. In this first small pit, shortly after, we observe a parallel pit with an entry window of 0.25X0.76 metres; this connects at its base with the other entrance at the base of the access pit. This other entrance is 0.48X0.30 metres.
We will descend through a crawlway with a turn to the right of about three metres. Here we find a small descending corridor profusely decorated with formations; in this passage 1.60 metres high by 0.90 metres wide, after advancing one and a half metres one reaches the head of a pit of -9.20 metres. At the end of the passage and beside the mouth of the pit, we observe a small impenetrable hole, which deepens 1 metre and connects with the aforementioned pit.
The mouth of this pit is 0.70X0.90 metres wide, although it immediately becomes a narrow passage that soon widens. Having descended this P-9, we observe a small parallel pit that begins at about three metres and connects at two points to the main pit, one of them not penetrable. The pit widens slightly and has walls covered with lithogenic formations. The base of the pit is about 3X1.50 metres, reaching the maximum level of -14 metres.
As its first explorers explain, somewhat higher up we find a hole with an interesting air current. It is possible that it communicates with the wall of the torrent.

Storia
Cavity discovered and explored on 31 March 1974 by the ERE of the AEC, but it went unnoticed, most probably because it was discovered after Joan Borràs published the three volumes of the “Catálogo Espeleológico del Macizo de Garraf”. For many years it was searched for by members of various Clubs without success; finally, based on the indications provided by Francesc Ximelis, one of the first explorers, on 22 February 2015, Carles Miranda and Enric Porcel (GEB) managed to locate the cavity.
