Description
Morphology
The cavity, structured along a S-N fissure, begins with a short conduit that gives way to a descending ramp of about 10 metres, which opens into a 12-metre vertical drop, followed by a second ramp of 14 metres; the average width of this section of the cavity is about 3 metres.
From this point, a rather significant clastic process, subsequent to an intense reconstructive process, has reconfigured the morphology of the cavity, subdividing the main gallery into two conduits between blocks, which skirt the walls that previously configured it; both galleries meet again at the end.
History
The first exploration was carried out by F. Monsonís of the ERE of the CEC in September 1968.
