Description
Morphology
The 3x7 metre entrance opens in the wall in the form of a large window, which gives access to a pit with a N-S orientation; at -28 metres we find a ramp 12 metres long with a 50º inclination; at the end of this and after a drop of about 3 metres a short ramp leads us to the final vertical of –16 metres; the total depth is -62 metres.
Other details
Along the pit we find on the walls a carpet of chough excrement, finding at the base of the pit a mound of this material a couple of metres high.
History
The first partial exploration was carried out on 20 March 1964 by 3 members of the S.E.C.E.S. of the C E Sabadell and on 22 and 23 July various members of the same club completed the exploration, which was accompanied by a hundred choughs that nest in the cavity. There is news that between these two dates, the unfortunate Josep Subils together with other companions also partially explored it.
