Its 10,500 square kilometers of endless white salt flats create one of the most impressive landscapes in South America. But this place has not always looked the way it does today. Before becoming the world\u2019s largest salt flat, this area was covered by ancient prehistoric lakes that slowly transformed over thousands of years. In this article, we\u2019ll explain the origin of Salar de Uyuni, how it was formed, and why this unique landscape became one of Bolivia\u2019s most iconic natural wonders.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How was Salar de Uyuni formed<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The area where the well-known Salar de Uyuni lies today was covered by Lake Ballivian, Lake Minchin and Lake Tauca.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It was the last one mentioned <b>from whose evaporation<\/b> the famous Salar de Uyuni was formed. Lake Ballivian was the predecessor of <a href=\"https:\/\/www.howlanders.com\/en\/tours-peru\/puno\/lake-titicaca\" title=\"Tour Lake Titicaca\">Lake Titicaca<\/a> and the Minchin left in its wake the lakes Poopo, Uru uru and Salar de Coipasa.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><iframe src=\"https:\/\/www.google.com\/maps\/embed?pb=!1m36!1m8!1m3!1d4278326.320898409!2d-68.82845440612917!3d-18.35153161933846!3m2!1i1024!2i768!4f13.1!4m25!3e0!4m5!1s0x93fd76595a229eb5%3A0xc707bdcae380096b!2sLago%20Poop%C3%B3%2C%20Bolivia!3m2!1d-18.7942434!2d-67.04645909999999!4m5!1s0x93fd4c7ba97fb751%3A0x25b844876346ecc4!2sLago%20Uru%20Uru%2C%20Bolivia!3m2!1d-18.1111043!2d-67.1179511!4m5!1s0x91568a8ad3cd9233%3A0xdac045a1ba3d47b7!2sSalar%20de%20Coipasa%2C%20Bolivia!3m2!1d-19.3832174!2d-68.16643309999999!4m5!1s0x915584b325e18bd7%3A0xce4183a158278b6!2sSalar%20de%20Uyuni%2C%20Bolivia!3m2!1d-20.1337772!2d-67.48913449999999!5e0!3m2!1sen!2ses!4v1614672500103!5m2!1sen!2ses\" width=\"600\" height=\"450\" style=\"border:0;\" allowfullscreen=\"\" loading=\"lazy\"><\/iframe><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These lakes reached an elevation of about 100 meters above the current level of the salt flat, and covered the current <b>salars of Uyuni and Coipasa<\/b>, and the lakes Poopo and Uru Uru. This situation was due to a wet phase with more rainfall than today.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When this period turned onto a dry and warm one, <b>the salt layers under the lakes<\/b> solidified. The result was the flat extension known today as Salar de Uyuni.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Composition of Salar de Uyuni<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The depth of the salt flat is 120 meters and it is composed of approximately <b>11 layers of salt<\/b>. Every layer has a different thickness and the one in the surface is the thickest. Between the layers, rainwater accumulates and is converted into brine (water with a high concentration of dissolved salt of more than 5%).<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"310\" src=\"https:\/\/i0.wp.com\/blog.howlanders.com\/wp-content\/uploads\/2021\/03\/uyuni-salt-flats-lithium.jpg?resize=640%2C310&#038;ssl=1\" alt=\"Lithium mountains in Uyuni Salt Flats\" class=\"wp-image-16326\" title=\"Lithium\" srcset=\"https:\/\/i0.wp.com\/blog.howlanders.com\/wp-content\/uploads\/2021\/03\/uyuni-salt-flats-lithium.jpg?w=825&amp;ssl=1 825w, https:\/\/i0.wp.com\/blog.howlanders.com\/wp-content\/uploads\/2021\/03\/uyuni-salt-flats-lithium.jpg?resize=768%2C372&amp;ssl=1 768w, https:\/\/i0.wp.com\/blog.howlanders.com\/wp-content\/uploads\/2021\/03\/uyuni-salt-flats-lithium.jpg?resize=124%2C60&amp;ssl=1 124w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The salt layer is formed by porous halite filled with <b>brine rich in lithium<\/b>, potassium, boron and magnesium.
