The Salar de Uyuni's salt crust covers a layer of extremely salty water or brine

Water also sits on top of the crust in some places due to a process called "freshwater upwelling"

The salt flat is surrounded by lofty mountains and volcanoes that supply water to the rim of the crust

It is almost 100 times larger than the famous Bonneville Salt Flats in Utah, USA

It is so flat that NASA uses its surface to calibrate sensors on board satellites, according to BBC Earth
