In the semi-arid regions of southern Africa, wildlife survives the dry season by visiting waterholes like this one, photographed on the flight into Vumbura Camp, Botswana. The trails used by animals which frequent the waterholes are clearly visible extending radially outward into the bush. Elephants play an important rôle in maintaining waterholes, as their wallowing for mud baths keeps the waterholes from filling up with silt.
