4. Bolivia’s Reflective Salt Flats
The world’s largest salt flat, Salar de Uyuni, can be found in Bolivia, covering an impressive 10,582 square kilometers. Located near the crest of the Andes, the Salar was created by the transformative conjunction of a number of prehistoric lakes. The flat’s salt crust lays atop a lithium-rich pool of brine, and the expansive area that Salar covers, combined with the rare surface flatness and clear skies, results in the world’s largest mirror: a great place for Narcissus to dwell.
