The endless expanse of the great salt plain Lake Assale located at 130 m below sea level in the northern Danakil depression near the Eritrean border. The surface crust forms hexagonal plates caused by evaporation and distribution of tension while the crust dries out. In this area, the salt deposit is several kilometers thick and tells about the tectonic force that rips Africa apart in this area, creating a deep trench, where sea water has invaded in the past and evaporated, leaving salt deposits behind.
