One of the hottest inhabited places on earth, the Danakil Depression in Dallol, Ethiopia had an average annual temperature of 94 F from 1960-1966, and the scorching wasteland is most famous for salt formations rising from toxic, green acid. None of this may sound particularly appealing, but the technicolor, ochre-green pools and flats are a sight to behold, resembling something from another planet. The lethal landscape is actually a source of life for the Afar people, who hack slabs of salt from the ground and transport them via camel for days at a time.
