Permafrost distribution in talus slopes located within the alpine periglacial belt, Swiss Alps
Abstract The extent of permafrost in nine talus slopes located within the alpine periglacial belt in the western Swiss Alps was investigated using ground surface temperature measurements and one‐ dimensional geoelectrical profiles. Based on the thermal data, permafrost appears likely in the lower pa...
