Green and White Surface of Etosha Pan, Namibia18.7S 16.4E
The Etosha pan is a large endorheic salt pan, forming part of the Kalahari Basin in the north of Namibia. The 120-kilometre-long (75-mile-long) dry lakebed and its surroundings are protected as Etosha National Park, one of Namibia’s largest wildlife parks. The area exhibits a characteristic white and greenish surface, which spreads over hundreds of kilometres.
The pan is mostly dry but after a heavy rain it will acquire a thin layer of water, which is heavily salted by the mineral deposits on the surface of the pan, which most of the year is dry mud coated with salt that splits into hexagonal shapes as it dries and cracks. Today it is seldom seen with even a thin sheet of water covering it.
