GOOD: Salar De Uyuni

http://good.is/

With an area about the size of New Jersey, Bolivia's Salar de Uyuni salt flat is known as the flattest place on earth. So when NASA needs to calibrate the satellite it uses to measure the melting of the polar ice caps, they point the ICESat's laser at the Salar de Uyuni first. One of earth's fascinating natural phenomena helping us gauge the fate of another. An original GOOD Video.
