Glacial scouring
The Alpine glaciers, that formed a network of ice streams during the high points of the ice ages, repeatedly flowed beyond the boundary of the Alps and advanced into the Alpine Foreland. There they formed vast foreland glaciers. In this Alpine Foreland glaciation, Penck identified a number of landforms: the ground moraines, the Zungenbecken, the terminal moraines and the gravel pl… WebFrom 2 million years ago to 10,000 years ago a series of glacial periods repeatedly covered the region with ice, scouring the bedrock and scooping out a great basin.
