Bòfia del Portet

The cavity opens to the outside among some blocks with a drop of about 2 m, which leads to a small gallery that is choked. At the base of the entrance drop we can continue descending between blocks, and other drops of 2 m, 2.5 m, 3.5 m, 4.5 m until reaching the level -22, where after a short gallery we reach a 4.5 m pit where its access had to be cleared. Then we must continue descending other pits of -3.5 m, -5 m and -12 m where various further clearings have been necessary, until the level -44 m where we have considered the cavity finished. Once at the base of the 12 pit, a climb of about 3 m has been made by which one can enter an ascending meander, (it is very narrow) that climbs back up again.

Geology: The cavity lies on monomictic breccias of the lower Oligocene. Facies of the upper Alluvial System of Berga. (Unit PObm), according to the bibliography consulted (1) in this place the breccias must have very little thickness, they are deposited on the micritic limestones of the Cuisian. Penya-Terrades Formation. (Unit PEcp1). Nevertheless it has not been possible to reach this limestone level, the whole cavity being developed in the breccias. According to this same work the cavity opens just vertically above the axis of the syncline along which the collector feeding the spring of the Font de Cal Sala (alt. 1067 m) should run.
