Description

Morphology

It has two entrance mouths. The upper one, more comfortable, is accessible by climbing a vertical section amid vegetation. The entrance half hidden by some blocks gives way to a short ramp with narrow walls that leads to a 3 metre drop. This drop with an irregular structure gives lateral access to a gallery of wider dimensions; at the ceiling of the gallery is the lower mouth, a hole opened artificially. At this point the gallery presents a strong unevenness and descends among large blocks; a short turn to the right leads to a room of medium dimensions completely covered with blocks.

History

Cavity cleared during 1996/1997 by the SEO del CE Vallirana.
