Located in Bolivia, Salar de Uyuni is the world’s largest natural mirror, a salt flat which formed some 40,000 years ago. After periods of rain, fresh water floats above dense brine to create a smooth, flat reflective surface.

Hosted by Joe Hanson, Overview is a series which explores unique aspects of our world by taking a different perspective.
