Rockglacier activity studies on a regional scale: comparison of geomorphological mapping and photogrammetric monitoring
Abstract In their spatial distribution as well as in their different states of activity, rockglaciers imply important information on former and recent permafrost conditions. Two different methods were applied in one study area (Turtmann Valley, Swiss Alps) in order to compare their suitability in as...
