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.

Seabed gouging by ice in orientation. This event is thought to be about 2000 years old. Recent episodes of grounding, gouging and fragmentation of large Antarctic icebergs have been observed to produce powerful hydroacoustic and seismic signals that further illuminate the dynamics of the process. In the offshore environment, the gouging features are made up of two kinds of ice: glacial ice and sea ice. Physically and mechanically, glacial ice is akin to lake ice, river ice and icicles. The reason is that they all form from freshwater (non saline water). Ice sheets, ice caps and glaciers essentially consist of glacial ice. Since glacial
