A worker ties together slabs of salt extracted from the Danakil Depression in northern Ethiopia April 22. Once the caravan find a suitable place to mine salt, they extract, shape and pack as many salt slabs as possible before starting their two-day journey to the town of Berahile. The Danakil Depression in Ethiopia is one of the hottest and harshest environments on earth, with an average annual temperature of 94 degrees Fahrenheit (34.4 Celsius). For centuries, merchants have travelled there with caravans of camels to collect salt from the surface of the vast desert basin. The mineral is extracted and shaped into slabs, then loaded onto the animals before being transported back across the desert so that it can be sold around the country.
