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.

Fluvio-glacial These hills can range in size and be up to 50 m tall and 400 m wide. A kame terrace is a relatively flat surface of sediment that was deposited between the valley surface and the glacier. When kames, kame surfaces, and other fluvio-glacial landforms are combined into one landscape, it is called a kame complex or glacial karst topography. Kettle holes are typically formed when a chunk of ice that came from the glacier is buried under fluvio-glacial sediments. Once the ice melts, the sediments fall and form a depression that can later be filled with rainwater and form
