How was salt crossed across the desert?

Salt was traditionally transported across deserts using caravans, which consisted of groups of camels or donkeys specially trained to carry heavy loads. These animals could withstand harsh conditions and travel long distances without water. Caravans would follow established trade routes, often making stops at oases for rest and replenishment. The trade of salt was crucial, especially in regions where it was scarce, making it a valuable commodity in ancient economies.
