Johannesburg - Geography

Geography

Johannesburg is located in the eastern plateau area of South Africa known as the Highveld, at an elevation of 1,753 metres (5,751 ft). The former CBD is located on the south side of the prominent ridge called the Witwatersrand (Afrikaans: White Water's Ridge) and the terrain falls to the north and south. By and large the Witwatersrand marks the watershed between the Limpopo and Vaal rivers. The north and west of the city has undulating hills while the eastern parts are flatter.

Johannesburg may not be built on a river or harbour, but its streams are the source of two of southern Africa's mightiest rivers. A number of streams meander through the suburbs of Johannesburg, and form the source of two of southern Africa's primary rivers – the Limpopo and the Orange. Most of the springs from which many of these streams emanate are now covered in concrete and canalised, accounting for the fact that the names of early farms in the area often end with "fontein", meaning "spring" in Afrikaans. Braamfontein, Rietfontein, Zevenfontein, Doornfontein, Zandfontein and Randjesfontein are some examples. When the first white settlers reached the area that is now Johannesburg, they noticed the glistening rocks on the ridges, running with trickles of water, fed by the streams – giving the area its name, the Witwatersrand, "the ridge of white waters". Another explanation is that the whiteness comes from the quartzite rock, which has a particular sheen to it after rain.
