Description
Morphology
At the bottom of the entrance funnel a shaft 6 metres deep begins, with an earthy entrance but solid walls. At its bottom, via a short ramp and a fairly narrow passage, one reaches a short chamber where we can stand upright. At its base we will observe that this small chamber is excavated thanks to a stratum of sandstones.
Hydrology
The cavity was a point of infiltration of the ridge that gives it its name: in cracks such as this one, water has been widening those that offered it least resistance, forming small points of filtration towards the interior of the massif to emerge at some spring or other; who knows whether, given its situation, it might not even feed the Caus del Guitard.
Progression
Update: In July 2020, during a visit by members of the SIS-CET, they observe that the narrow passage that gave access to the final small chamber is filled with sediments.
History
Discovered in April 1987 while clearing the part burned in the fire of the previous summer. The woodcutter Elies Sánchez, questioned by Jaume Claverí, provided him with the location.
The first exploration took place on 10 January 1988 by J. Claverí and J.A. Pérez (GES – CM Terrassa), but they did not reach the final small chamber, whose access was closed by the branches from the clearing of the forest. This small chamber was discovered the following month when members of the SIS – CET and Jaume Claverí made the second exploration and survey.
