Gcwihaba

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. 
Gwchihaba is a Botswana National Monument under the Monuments, Relics and Antiquities Act, and has been put forward to become a UNESCO World Heritage Site in 1999. It is the type locality of the mineral gwihabaite (IMA1994-011).
Even though nothing was found in the first 50 cm of cave during the excavations to affirm that the cave was settled as a camp, 51 stone artefacts (33 of them made from travertine)  were released in the upper  50 cm of the cave. 50-80 cm of the cave is called The Terminal Pleistocene charcoal layer. More cultural relics were observed in this layer. Bones of African bullfrogs and pieces of ostrich eggshell were among the findings.
