Karoo National Park Escarpment in the Karoo is also formed, in many places including the Karoo National Park, by a thick dolerite sill. The vegetation consists primarily of dwarf (less than 1 m high) xerophytic shrubs with some grasses. The shrubs and grasses are deciduous, mainly in response to the irregular rainfall Karoo National Park The Karoo National Park, founded in 1979, is a wildlife reserve in the Great Karoo area of the Western Cape, South Africa near Beaufort West. This semi-desert area covers an area of . The Nuweveld portion of the Great Escarpment runs through the Park. It is therefore partly
Karoo Group (i.e. the oldest layer of the Cape Supergroup). The valley floor is covered, in the main, by the next (younger) layer of the Supergroup, namely the much softer Bokkeveld shales. The dolerite of the Great Karoo did not penetrate these rocks, so Karoo Koppies are not seen in the Little Karoo. The Little Karoo contains two other geological features that give the landscape a special character. During the erosion of the African interior following the bulging of the continent during the massive lava outpourings that ended the Karoo sedimentation 180 million years ago, some of the eroded material was
