Witwatersrand

The Witwatersrand is a large sedimentary range of rocky hills in South Africa. Although it has an elevation of 1700–1800 metres above sea-level, it appears low because of the average height of the surrounding mountain plateau. The Witwatersrand runs in an east-west direction through Gauteng. The word in Afrikaans means "the ridge of white waters".

Geologically it is complex, but the principal formations are quartzites, conglomerates and shales of the Witwatersrand System.

The Witwatersrand range forms a continental divide with rivers to the north such as the Crocodile River draining into the Limpopo River and Indian Ocean and with the run-off to the south draining into the Orange River and Atlantic. The Witwatersrand lies within the province of Gauteng, formerly called the PWV area, an acronym for Pretoria, Witwatersrand, and Vereeniging.
