Summary. — The first part of this study (published in the fascicule 2, 1977, of the Revue de Géographie Alpine) described the glacier retreat of these last years and the morphological evolution that go with it ; the rock-glaciers are certainly the remains of different glacier retreats. But the Vallon de la Rocheure also presents a collection very complete of periglacial forms and microforms that show the present activity of physical processes as to solufluxion, vertical and horizontal selection of rock fragments, particularly between 3 000 and 2 600 m. This space seems to be the more frequently submitted to cycles frost- thaw. Above, snow and ice are the principal factors of the morphological evolution ; under, the vegetation partly protects slopes. Source : Éditeur (via Persée) |
