Salt Lake, Namibia, Africa

A salt lake or saline lake is a landlocked body of water that has a concentration of salts (typically sodium chloride) and other dissolved minerals significantly higher than most lakes (often defined as at least three grams of salt per litre). In some cases, salt lakes have a higher concentration of salt than sea water, but such lakes would also be termed hypersaline lakes. An alkalic salt lake that has a high content of carbonate, is sometimes termed a soda lake.

Saline lake classification:

subsaline 0.5–3 ‰
hyposaline 3–20 ‰
mesosaline 20–50 ‰
hypersaline greater than 50 ‰

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 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.
