With its characteristic frowns, its steep, multi-lobed front, its unstable boulders, the rocky glacier is a spectacular mixture of ice and stones which flows slowly along a mountain slope. It is thus distinguished from the white glacier, consisting entirely of ice, and the black glacier covered with rock debris. The Southern Alps contain superb rocky glaciers, such as that of Asti (Queyras), those of Marinet (Haute Ubaye) or those of the circus of Sainte-Anne (Queyras). But for the activity of such a glacier to continue, the annual average air temperature must imperatively remain below -2 ° C. Will the rocky glaciers of the Southern Alps all become inactive with climate change?
