Description
Morphology
The entrance, occupied by a large amount of vegetation, gives way to a descending gallery 6 metres wide. At the end of the gallery (- 10) and on the left-hand side, a 55º ramp leads to a room measuring 12 x 22 metres, covered with blocks of all sizes. At the S end, a prolongation of the same room, separated by blocks, forms a small room with a low ceiling.
The cavity was formed following the dip of the strata, which in this sector is about 25º. Subsequently, in the room, a clastic process occurred prior to the equilibrium state of the vault.
Speleothems
In the entrance gallery there is a large column. Also noteworthy is the flowstone located at the N end of the room.
Progression
The entrance gives way to a descending gallery. At the end of the gallery (- 10) and on the left-hand side, a 55º ramp leads to the room.
History
The first news of which we are aware is of the exploration carried out by members of the ERE – CEC on 30 May 1982.
