The hand-axe extraction of salt blocks from Lake Assal, Africa's lowest point (155 meters below sea level) and one of the saltiest lakes on Earth, by Afar and Issa salt workers of Djibouti's Afar Rift. Workers break open the lake's thick salt crust -- documented as ranging from 20 to 80 meters in depth, with over six million tonnes of salt deposited in the area annually -- using hand axes under extreme desert heat (summer temperatures reaching 52°C), extracting workable blocks directly by hand near the shoreline. Historians estimate the salt trade at Lake Assal has continued since the sixth century; salt was historically transported by camel caravan to inland markets, particularly the Ethiopian highlands, traded for goods including coal, coffee, and historically ivory and, in earlier periods, people. During the 1998 Ethiopian-Eritrean War, Djibouti became Ethiopia's primary salt supplier, earning Lake Assal's salt the nickname 'white gold' and prompting a shift toward heavier mechanized extraction methods to meet surging demand. Traditional hand-axe harvesting continues today alongside large-scale commercial and increasingly Chinese-funded industrial extraction operations, with individual traditional harvesters -- documented through the direct account of salt worker Hummad Musa -- now selling much of their hand-extracted salt to tourists and to the thousands of foreign personnel stationed at Djibouti's multiple international military bases (American, Chinese, Japanese, and French), rather than through the historic long-distance caravan trade.
