4085 square mile natural mirror

The world's largest salt flat, the Salar de Uyuni in Southwestern Bolivia (near the crest of the Andes, 3,650 meters high), is one of the most exotic place sceneries on earth. There is an estimated 10 billion tons of salt in the flats, 25 times the amount in the Bonneville Salt flats in Utah in the United States. The 4085 square mile salt flat looks like a scene from another planet. The endless sea of white salt is paired with small islands, which are small rocky hills of earth cluttered with odd plants such as cacti. The flats were once part of a large lake more than 40,000 years ago.
