Gcwihaba is a cave in Botswana located in Okavango Delta region. The Gcwihaba Caves were part of the Kalahari landscape around 2 million years ago, at least for the entire period of the Pleistocene. The name of the cave is a San word and stands for "hyena's lair". The cave is situated 10 km away from the Namibian border. In 1932 it was first shown to a European, Ghanzi region farmer Martinus Drotsky, and the main cavern was named Drotsky's cavern after him.
