Namibian drumlins

The Namibian drumlins are a geologic feature in Namibia. Since drumlins only occur as the result of glaciers, researchers determined they are the relic of an ice age in the late Paleozoic Era.^[1] The researchers measured the supposed rock drumlins with satellite imagery available on the Internet. "Megalineations" including rock drumlins were described at approximately 20°33′S 14°21′E, between Twyfelfontein and Xaragu Camp.^[2]
