Avenc del Tossal de Cantacorbs

It is a very unstable clastic cavity. Once the entrance is cleared, a small 35x35 cm opening leads to a 5 m shaft that places us in a small chamber of 4x10 m; to the south of the chamber another 6 m shaft opens, while to the northwest the joint narrows until it becomes impenetrable.

From the base of the entrance shaft, following the joint between blocks in a southeast direction, one reaches another 9 m shaft, where the joint gains greater extent until it closes and becomes impenetrable.
