Lac 'Assal

Lake Assal is a crater lake in the Danakil Desert in central Djibouti. Dormant volcanoes and black lava fields back its emerald water. More than 150m below sea level, it's the lowest point in Africa. The wet section of the lake is a body of extremely salty water fed by hot springs. The dry section features a white salt bed from which lake water evaporated over the years. Salt is extracted in slabs from this section.
