Image Caption:
Western Extension of the Reef T45
The Reef is the name given to the 300 km-long series of gold min-
ing towns on the central plateau of South Africa. Rectangular
mine dumps of waste material from the westernmost gold mines of
Klerksdorp and Orkney, are prominent (left center). The
Afrikaans- language university town of Potchefstroom (1) is si-
tuated on the Mooi ("beautiful") River and the vacation town of
Parys on the Vaal ("grey") River (2). The Vaal marks the boun-
dary between the provinces of Transvaal (top) and Orange Free
State (bottom): it is not clear why the latter shows signifi-
cantly more soil erosion (light brown field patterns). (61A-39-
