About this photo

There are several salt flats in Chile, but the Atacama Desert salt flats (also known as the San Pedro salt flats) are the largest in the country. The Atacama salt flats boasts a total area of 1,200 square miles, but the largest salt flat in the world can be found in neighbouring Bolivia.

Salt flats are formed when a large body of water, such as a lake, evaporates over time, sometimes as a result of the changing climate, leaving behind salt and other minerals that were dissolved in the water. For a salt lake to form, the rate of evaporation must be higher than the rate of precipitation, which explains why salt flats usually tend to appear in deserts. This factor also adds to the surreal effect of a salt flat; their bright, white glows make them look more the kind of thing you'd find in an Arctic tundra than in the middle of the desert.
