Makgadikgadi Pan (nonfiction)

The Makgadikgadi Pan (Botswana salt flats)(Tswana pronunciation [maqʰadiˈqʰaːdi][needs tone]), a salt pan situated in the middle of the dry savanna of north-eastern Botswana, is one of the largest salt flats in the world. The pan is all that remains of the formerly enormous Lake Makgadikgadi, which once covered an area larger than Switzerland, but dried up several thousand years ago.
