Short summary
This article studies the ice flow in the Valais region during the last glaciation (Würm) in detail. The numerical modelling shows a discrepancy of the height of the ice cap compared to the geomorphological evidence based on trimlines. However, geomorphological evidence at the Simplon Pass indicating an ice flow from the Rhone valley into the valley of Toce was confirmed. Furthermore it is shown that for this confirmation a sufficient ice thickness is obligatory.
