Matter Valley

Towering above the Matter Valley field side are Nadelgrat, Dom and Taeschhorn. View from above the Randa rockfall (Grossgufer).


The objective of the field site on the orographic right side of the Matter valley above Herbriggen/Randa is to investigate different types and scales of mass movements. The  study area spreads from the Breithorn/Gugla area in the north all the way to the Grabengufer in the south. At present it is our largest field site. The aim of our measurements there is to quantify the velocities of various movements types in seasonal and perennial frozen debris slopes and rock glaciers. For this purpose we are using L1-GPS devices mounted on top of prominent boulders tracking their position continuously as well as high-resolution cameras.
