Kubu Island, Makgadikgadi Pan, Botswana: This granite rock island sits on the Makgadikgadi Pan, the largest salt flat complex in the world, in a desert of northern Botswana. The salt pans cover the bed of the ancient Lake Makgadikgadi, which began evaporating millions of years ago. For most of the year, the dry stark landscape, uninhabited by humans, is marked by fossil beaches and large, spectacular baobab trees.
