A salt flat, also known as a playa or alkali flat, is a flat, dry lake bed found in arid or semi-arid regions. These landforms are characterized by their extreme flatness, with slopes often less than 0.2 meters per kilometer.1

Salt flats form when water in interior basins or near coasts evaporates, leaving behind deposits of salt, sand, and mud. They can be saline, containing high concentrations of salts like sodium chloride, or salt-free, composed primarily of clay. Famous examples include the Bonneville Salt Flats in Utah and the Uyuni Salt Flat in Bolivia, which also holds vast lithium reserves. These environments are sensitive to climatic changes and can be sources of dust and salt blown by the wind.123
