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.

Nooitgedacht Glacial Pavements Nooitgedacht Glacial Pavements The Nooitgedacht Glacial Pavements comprise a geological feature between Kimberley and Barkly West, South Africa, pertaining to the Palaeozoic-age Dwyka Ice Age, or Karoo Ice Age, (some 300 million years ago) where the glacially scoured (smoothed and striated) ancient bedrock (re-exposed by erosion) was used, substantially more recently, during the Later Stone Age period in the late Holocene as panels for rock engravings. Some 300-290 million years ago, during Dwyka times, what is now Southern Africa was, as a result of plate tectonics, near the South Pole and large ice sheets or glaciers covered high-lying areas.
