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 / 20.55°S 14.35°E / -20.55; 14.35, between Twyfelfontein and Xaragu Camp.^[2]
