salt trade caravans of Lake Assal
This airmail stamp depicts the historic salt trade caravans of Lake Assal (Lac Assal), issued in 1958 by the French administration in the French Somali Coast (Côte Française des Somalis, modern-day Djibouti). Lake Assal, a endorheic crater lake situated over 150 meters below sea level, is one of the saltiest bodies of water on Earth and has served as a critical economic hub in the Horn of Africa for centuries.
The event commemorated on the issue centers on the traditional extraction and transport of salt by Afar and Somali salt workers (sauniers). Workers harvested the naturally crystallized salt crusts along the lake's shores and loaded them onto camel caravans. These salt routes traversed arduous desert tracks across the Danakil Depression to trade networks in the Ethiopian Highlands, where salt blocks historically functioned as a vital commodity, essential nutrient, and form of currency.
