Description

Morphology

The cavity begins with a spacious pit 27 m deep (2x4 m). At its base, the top of a second 36 m shaft had to be cleared. At -65 m, a large block forms a ledge followed by a P.10 and 2 steps of 5 and 7 m. The continuation is via a final 17 m pit in a joint. A 2 m climb and then a gallery lead to a muddy step giving access to a chamber blocked by a debris cone (fault).

Hydrology

Torca 366 probably feeds the upper reaches of the Cueto-Coventosa system, which currently end beneath the Bucebron depression.
