Salar de Uyuni

This week’s “Where in the World?” location has been deemed the flattest place on Earth as well as the world’s largest natural mirror!

The Salar de Uyuni

Covering an area larger than 150 countries in the world, the Salar de Uyuni is the world’s largest salt flat. Located in the Potosi region of Bolivia, and stretching almost 4,050 square miles, it was left behind by prehistoric lakes that evaporated. It sits 11,984 ft above sea level and the view is typically of a thick crust of salt that extends as far as the eye can see. It can even be viewed from space!

It is believed that an estimated 11 BILLION tons of salt are located within Salar de Uyuni.

Salt

However, in the rainy season, as nearby lakes overflow, it leaves a thin layer of water settling across the top of the salt. The water reflects the blue and white images of clouds and sky from above and the horizon disappears. Those driving across the area describe it as appearing to fly through the crowds.
