Deep-seated rock slope failures represent effective mechanisms of natural rock mass-wasting, able to radically change mountain-valley morphology.In the northern Cottian Alps, an extraordinary concentration of instability phenomena occurs in extensive areas of the Susa and Chisone valleys.In the Main Map, at poise pads in bulk a scale of 1:30,000, a new representation of these deep-seated rock slope failures is proposed.Major effort has been invested in properly distinguishing between sackung-type deep-seated gravitational slope deformations and large landslides.

Gravitational phenomena have affected the mountain landscape, with the development of impressive morphostructural features such as multiple-crested ridges and ridge top depressions.In the middle and distal portions of miracle academy clothing the slopes, sagging and toe bulging impose a marked change in the valley-slope profiles, in turn inducing secondary slope instabilities.Furthermore, mature deep-seated gravitational deformations and large landslides have, in some cases, made a significant impact on valley bottom morphology due to a partial or complete valley dam.
