Location

From Viozene, follow the path to the Bocchin d'Aseo; before the last step below Pian dell'Olio, climb to the left (W) up the steep little gully, also called Canalino Barattolo, as far as the clearly evident ledges of Jurassic limestones. From here, moving to the left after about fifty metres, the entrance of M-1 opens; continuing south, at the base of the cliff, a steep grassy little gully leads, after climbing about thirty metres, to the M-10 cave (adapted from: Bollettino del Gruppo Speleologico Imperiese CAI; text: Gilberto Calandri).

Description

Morphology

The small entrance, in the Jurassic limestones, leads into a descending sub-elliptical conduit, typical of a full-flow tube, with evident morphologies such as corrosion pockets, scallops and smoothed surfaces. The pressure conduit continues at a regular gradient (ca. 30°) bending sharply to the south until it is obstructed by clastic fill. Fossil cavity, relic of a Cenozoic phreatic network (adapted from: Bollettino del Gruppo Speleologico Imperiese CAI; text: Gilberto Calandri).

Speleothems

On the walls and ceiling, in patches, there are deposits of mondmilch, linked to percolation water, clearly corresponding to microjoints (adapted from: Bollettino del Gruppo Speleologico Imperiese CAI; text: Gilberto Calandri).

Other details

On the bottom there is minute rubble, mainly from gelifraction and from outside contributions (adapted from: Bollettino del Gruppo Speleologico Imperiese CAI; text: Gilberto Calandri).
