The Nuweveld Mountains near Beaufort West
A stylized illustration of the Great Escarpment, based particularly on its appearance in the Great Karoo, where thick erosion resistant dolerite sills (see below; represented here by the thick black lines. The thinner dolerite sills are not drawn in this diagram to avoid clutter) 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.) Note the island remnants of the earlier extent of the plateau on the plain below the escarpment (the Lower Karoo), left behind as the escarpment has gradually eroded further inland.
Farmlands along the well-watered, fertile foothills of the more than 2000 m-high Swartberg Mountains (in the background) along the northern strip of the Little Karoo
A schematic geological map of the outcrops (surface exposures) of the Karoo Supergroup rocks in Southern Africa: The location and approximate structure of the Cape Fold Mountains are also diagrammatically indicated for reference purposes.
Flat-topped hills (called Karoo Koppies) are highly characteristic of the southern and southwestern Karoo landscape.
A diagrammatic 400 km north-south cross-section through the southern portion of the country at approximately 21° 30' E (i.e. near Calitzdorp in the Little Karoo), showing the relationship between the Cape Fold Mountains (and their geological structure) and the geology of the Little and Great Karoo, as well as the position of the Great Escarpment. The colour code for the Karoo rocks is the same as those used in the above diagram. The heavy black line flanked by opposing arrows is the fault that runs for nearly 300 km along the southern edge of the Swartberg Mountains. The Swartberg range owes some of its great height to upliftment along this fault line. The subsurface structures are not to scale.
Two separate and independent Karoo biomes, or botanical regions, of South Africa bear the name Karoo: the Succulent Karoo to the west of green line, and the Nama Karoo to the east.
