Description
-
Pietre Grosse is a geosite located on Mount Bo, known for its significant landslide event in the 17th century. The landslide led to the detachment of large boulders, which now characterize the rugged terrain.
-
The landslide is of particular interest for studying catastrophic geological events and their long-term impact on landscape formation.

Lithology
-
mica schist
-
quartzite
-
The geosite features metamorphic lithologies, particularly eclogitic micaschists, which are part of the Sesia Lanzo Zone. These rocks have been subject to high-grade metamorphism. The landslide event exposed these rocks, leaving behind boulders and rocky outcrops that form the unique landscape of the site.
