Salar de Uyuni is the world’s largest salt flat that covers more than 12,000 sq, Km. Heaped upon the lands of Salar de Uyuni are piles of salt deposits.

The salt flat is located in the Potosi and Oruro departments of southwest Bolivia, near the crest of the Andes. It is at a height of 3,656 meters, about 11,995 ft above the main sea level.

Salar de Uyuni is 25 times larger than the Bonneville Salt Flats in the United States. Salar de Uyuni in Bolivia is also the highest salt flat in the world at three thousand seven hundred meters above sea level.This salt flat is the remains of a prehistoric lake.

How did the salt flats of Salar de Uyuni form?

The land of Salar de Uyuni is completely surrounded by mountains, and there are no outlets for the water to drain. The water dries up leaving behind salt deposits on the surface of the lake.

The Salar de Uyuni salt flat was formed by the transformation of many lakes that were part of a giant prehistoric lake, "Lake Minchin" about 30,000 to 42,000 years ago.

These flats are covered by thick salt crusts. They serve as natural resources of salt. The center of Salar de Uyuni has many small islands located on top of dormant volcanoes that were submerged by Lake Minchin. These islands have coral like fossil structures covered by algae.

The Salar de Uyuni salt flat is so level that the surface is used to calibrate the altimeters on board satellites. Beneath the salt flat of Salar de Uyuni, there are about 9 million tonnes of lithium - that is more than a quarter of the world’s known resources according to the US Geological Survey.

Salar de Uyuni has ten billion tonnes of salt. Twenty five thousand tonnes of salt is extracted every year.

The salt flat becomes the world’s largest mirror when covered with water. Pink Flamingos come here to breed during the wet season.

      RTalloni, yes that is true a lot of mining is taking place in Bolivia and this will destroy the salt flats little by little. Thank you for sharing your important views we need to save what is left of Planet Earth.

      Thank you for this look at Salar de Uyuni. It would be a amazing to see it first hand and be able to take photographs of it in different lights on a seasonal basis. I imagine the colors would be astounding.

      It is always interesting to see inexplicable places in the world, as well as to see people's responses to them. We have so much to learn, yet with words to explain what they do not know as fact, assumptions are made about a place like this and used to summarize theories so business/science can attempt to "utilize" its resources before understanding all the ramifications. Learning from Bolivia's own experiences with mining operations rather than dismissing them would be huge for real progress there. To be good stewards of the earth is to see the most protection and benefit for everyone involved.

      We have salt flats down here, but by far not as large as Salar de Uyuni. "Pure white brilliance!!" - is an awesome picture. I enjoyed the video - A tour of Salar de Uni.

      Thank you, vellur, for this most interesting hub about the world's largest salt flats.

      I never heard of this place. Thanks for telling us about what seems to be an amazing place. I didn't vote for going there, but I can see why some would want to see it. Now I have to find out why the flamingos like to breed there. Is it the salt or the remoteness of the area? Well done. Pinning.

      This is so interesting. I avoid salt like the plaque but when I do have some it is the course sea salt which pops on the tongue and is a real treat.

      Great video. ^

      This is a great hub. Something which I have never heard of before. The salt flats look beautiful...much like frozen ice. That picture inside the hotel, interesting. Wondering, they cannot use metals that react to salt in that area I guess and many more items will get easily damaged including electronics.

      Thank you for sharing this information with us. Beautiful photos. I love the one with the flamingos.

      Voted up and sharing!
