Central Kalahari Game Reserve is an extensive national park in the Kalahari desert of Botswana. Established in 1961 it covers an area of 52,800 square kilometres making it the second largest game reserve in the world.
The park contains wildlife such as South African giraffe, brown hyena, warthog, South African cheetah, Cape wild dog, African leopard, Transvaal lion, blue wildebeest, eland, gemsbok, kudu and red hartebeest. The land is mostly flat, and gently undulating covered with bush and grasses covering the sand dunes, and areas of larger trees. Many of the river valleys are fossilized with salt pans. Four fossilized rivers meander through the reserve including Deception Valley which began to form around 16,000 years ago.
