Abstract

This paper describes a remote sensing-based approach for detailed topographic investigations in steep periglacial high-mountain faces. The study was conducted in the European Alps, at the permafrost-affected and partially glacierised east face of Monte Rosa. A time series of high-resolution digital terrain models (DTMs) with a 2-m resolution was produced from digital aerial photogrammetry for 1956, 1988 and 2001 and from airborne LiDAR for 2005 and 2007. Analysis of all unstable areas and detachment zones showed that the sequence of the main slope failures is spatially connected and that there is coupling between permafrost bedrock instability and the condition of adjacent hanging glaciers
