Kopjes & Lakes in the Serengeti
The Afrikaans ‘kopje’ (pronounced copy) is the term commonly used in East Africa for the rocky outcrops technically known as inselbergs. They consist of very old granite rock, which, because of erosion and weathering, has broken up into a rough and jumbled surface. In the open grasslands, where the countryside has been more or less leveled off by deposits of dust and ash from volcanoes of the Rift, kopjes stand out against the surrounding plain.
