Great Escarpment, Southern Africa

A map of South Africa showing the central plateau edged by the Great Escarpment and its relationship to the Cape Fold Mountains in the south. The portion of the Great Escarpment shown in red is officially known as the Drakensberg, although most South Africans think of the Drakensberg as only that portion of the Escarpment which forms the border between KwaZulu-Natal and Lesotho. Here the Escarpment rises to its greatest height of over 3000 m.Satellite image of South Africa. If this image is compared with the map on top, the Great Escarpment can easily be identified.

An approximate SW-NE cross section through South Africa with the Cape Peninsula (with Table Mountain) on the far left, and north-eastern KwaZulu-Natal on the right. Diagrammatic and only roughly to scale. It shows the major geological structures (coloured layers) that dominate the southern and eastern parts of the country, as well as the relationship between the Central Plateau, the Cape Fold Mountains, and the Drakensberg escarpment. The south western escarpment (the Roggeberg escarpment) is also clearly visible on the left, but is not labelled. The significance and origin of the geological layers can be found under the headings

A stylized illustration of the Southern African Great Escarpment, based particularly on its appearance in the Great Karoo, where thick erosion resistant dolerite sills (represented by the thick black lines in the diagram) generally form the upper, sharp edge of the escarpment. In other parts of the Escarpment hard erosion resistant geological layers similarly form the upper, abrupt edge (see text). Note the island remnants of the earlier extent of the plateau on the plain below the escarpment, left behind as the escarpment has gradually eroded further inland.[8]

The Great Escarpment, which edges the central Southern African plateau, is a major geological formation in Africa (See "Geological origins" below). While it lies predominantly within the borders of South Africa, in the east it extends northwards to form the border between Mozambique and Zimbabwe, and in the west it continues northwards into Namibia and Angola.
