Description
Morphology
Through an entrance of regular dimensions (approx. 3 x 2 m.) one enters a small shaft 5 metres deep, at the base of which begins a gallery about 13 metres long that, on a steep ramp, leads into a wide and beautiful chamber. At the end of this chamber one can see the entrance of a slightly elevated gallery protected by a series of magnificent gours. At its start the gallery has a rounded section with a low ceiling, then a few metres further on gains height for a few metres and immediately afterwards noticeably decreases in dimensions. Once the narrows are passed, one emerges into a wider passage, slightly ascending, where some parietal flowstone brings the progression to an end.
Speleothems
The entrance of a slightly elevated gallery is protected by a series of magnificent gours (very often full of water and for which the greatest respect is asked of visitors).
Hydrology
In times of heavy rain the cavity can enter a certain hydrological activity and the gallery is traversed by a small watercourse, which drains through a small sinkhole in the main chamber, below the gours.
Progression
Through an entrance of regular dimensions (approx. 3 x 2 m.) one enters a small shaft 5 metres deep, at the base of which begins a gallery about 13 metres long that, on a steep ramp, leads into a wide and beautiful chamber. Once the narrows are passed, one emerges into a wider passage, slightly ascending, where some parietal flowstone brings the progression to an end.
History
Very possibly the discovery and first exploration of the cavity took place in December 1955, as recorded in the activities book of the GES del CMB, thinking that the authors of this exploration would have been members of its delegation in Terrassa (years later Club Muntanyenc de Terrassa).
We know of another visit in 1964 by two members of the Centre Excursionista de Terrassa, Enric Prat and Joan Estella, who were two of the founders a few years later of the SIS.
