Salar de Uyuni

Salt mounds in Salar de Uyuni, Bolivia, the world's largest salt flat. It is the remnant of a prehistoric lake surrounded by mountains without drainage outlets. Salt is harvested in the traditional method: the salt is scraped into small mounds for water evaporation and easier transportation, dried over fire, and finally enriched with iodine.
