The depression lies 100 meters below sea level and is one of the world's hottest and most inhospitable locations, with National Geographic calling it the "cruelest place on Earth."

Despite temperatures that reach over 50 degrees centigrade, it remains a lively and important economic hub, where Ethiopians maintain a centuries-old industry of mining salt from the ground by hand.
