Pozzo C-10 di Piaggia Bella

Pit in the compact limestone of the Jura, with a triangular entrance (2 by 2 m), 19 m deep, formed of two parts: the first, along a fracture, inclined at 50°, and the following sub-vertical one with a SW-NE direction. The first section is oblique, with a floor of furrows and ridges that continue the forms of the lapiaz surrounding the entrance. At -7 m the vertical section begins, first slightly overhanging on the east wall, then on the west one. The floor, a flat debris floor, has an almost elliptical plan (4x1.5 m).

The floor retains snow until September. The morphologies present suggest that this is a pit originated by corrosion. The connection with the outside appears to be later than the formation of the cavity.
