2. The World's Largest Natural Mirror
Usually from December to April, the rainy season converts the salt flat into the biggest natural mirror in the world by a thin layer of water.This amazing event produces a perfect mirror of the sky, therefore making it impossible to tell where the earth ends and the heavens start.Though this small pool produces an optical sense of boundless depth, the water depth seldom reaches 30 cm.NASA utilizes photos of Uyuni to calibrate satellites for measuring Earth's albedo as the flat surface of the salt crust mixed with the high mineral content of the water creates a reflection so ideal.One of the most strange settings on Earth, the salt flat is a photographer's heaven thanks to this mirror effect.
