This is a lovely shot of the salt mounds in Salar de Uyuni, Bolivia. The Salar de Uyuni is the world’s largest (12 000 km²) and highest (3,700 m) salt flat, ca. 25 times as large as the Bonneville Salt Flats. It’s 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.
