Mondo Knows Facts

Salar de Uyuni is the world largest mirror during the rainy season

Spanning over 10,000 square kilometres in Bolivia, Salar de Uyuni is the largest salt flat on Earth.

Formed as a result of transformations between several prehistoric lakes, this vast salt crust sits at an altitude of nearly 3,700 metres in the Andes. During the rainy season, a thin layer of water covers the flat surface, transforming it into a giant natural mirror. Beneath the salt crust lies a massive reserve of lithium.
