Rock glaciers evolution in Late Glacial and Holocene inferred from the new palaeoclimatic data
Rock glaciers are landforms made of mountain permafrost creeping under the effect of gravity and characterized by a particular topography of ridges and furrows ended with a steep front. By decoding their present morphology and understanding their altitudinal distribution, a variety of aspects of the...
