Rock glaciers, Prealps, Vaud, Switzerland, Version 1

The investigated area forms part of the western lobe of the Prealps (Swiss Prealps). The 25 identified fossil rock glaciers are found mainly in the Prealpes medianes rigides Nappe and the Niesen Nappe, at altitudes of 1500 to 2100 m. They represent at least three generations of fossil periglacial forms of late-glacial age (older than Balling), at about 1200, 950, and 700 m below today's permafrost boundary, respectively. These fossil features are related to glacial stages and form part of a detailed late-glacial morphostratigraphy. Information stored in a file includes: orientation, elevation of the source and the front, area, type of form, type of material, lithology, generation. These data are presented on the CAPS Version 1.0 CD- ROM, June 1998.
