Dwyka

Dwyka

Dwyka is the name of a river in the Karoo in South Africa, adopted by geologists to define the Karoo Ice Age some 300 million years ago. Key sites in South Africa show evidence of glaciation, including Nooitgedacht near Kimberley. In South Africa, near the South Pole at that time as a result of plate tectonics, large ice sheets or glaciers covered high-lying areas. Geologists term this upland the Cargonian Highlands, stretching from what is now the Northern Cape through Gauteng to Mpumalanga. [1]
