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.

Buried valley Europe. Recently, research has been focused on understanding the sedimentology of these formations in an effort to determine the safety of continued use of the aquifers which are often found in them. Buried valleys are created when ancient river or stream valleys are present that predate the most recent glaciation, and since have been filled with glacial till and/or outwash. In the Pleistocene, advancement and retreat of glaciers carved out the preexisting valleys, and deposited the material that had accumulated in the glacier by the melting of either the glacial outwash or the melting of the ice that composed the
