Drumlin were formed during the Wisconsin glaciation. Drumlins are found at Tiksi, Sakha Republic, Russia. Extensive drumlin fields are found in Patagonia, for example near Punta Arenas Carlos Ibáñez del Campo Airport and on Navarino and Gable Island in the Beagle Channel. In 2007, drumlins were observed to be forming beneath the ice of a West Antarctic ice stream.

Glacial series the glacial sediments and sedimentary rocks associated with glaciers and classified by their geological features. A complete glacial series is formed when the edge of the ice sheet remains static for a long time and is not destroyed again by a further advance of the ice mass. 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
