Description
Morphology
Through an entrance split in two by a wedged block, one enters a shaft 16 metres deep, where almost halfway down its descent there is another block wedged between the walls of the diaclase. At its base, and in a S direction, a small ramp conduit can be followed that ends after a few metres and where the point of maximum depth is reached. At the two ends of the bottom of the shaft, ascending steps can still be overcome that allow height to be gained through the narrowest zones of the diaclase.
Speleothems
The lithogenic process is quite abundant.
History
We do not know who or when the first exploration was made. The oldest news we have is the visit by members of the GES-CMB in June 1954.
In 1970 members of the Espeleo Club de Sabadell made the only survey that we know of.
