Descrizione
Morfologia
A narrow vertical entrance gives access to two conduits, the first of which is ascending and leads to a small chamber, and then the conduit becomes impassable.
Following down from the mouth, a small pit 6 metres deep develops, ending blocked by sediments.
Idrologia
It seems to be an old sinkhole of the riera, hanging at very little height above the current streambed and which possibly in times of heavy rain may temporarily become active.
Storia
A cavity well known for a long time by the people of the area. The first report is given by members of the SIE – CEA who explored it on 29 October 1972, naming it Avenc de Santa Marina.
Two years later, on 12 October 1974, members of the GE Pedraforca (Barcelona) visited and surveyed it, calling it Avenc de Coll Roig, although it seems that at first they called it Avenc de la Benzina.
We can add that on the map Serra de Llaberia (Editorial Piolet), at this location they georeference a cavity with the name Avenc de Sant Miquel, which must certainly be the same one.
