How Important is Salar de Uyuni?

There are many different salt flats located around the world, but none have quite the same magnitude as Bolivia’s Salar de Uyuni.

From its size to its regional significance, Salar de Uyuni continues to fulfill the needs of mother nature, as well as mankind.

The History of Salar de Uyuni

According to legends, the origin of Salar de Uyuni is far more mystical than the idea that mother nature helped to create it.

If you ask many who believe the Aymaran legends, they say that the mountains surrounding Salar de Uyuni were gods.

Their belief is that the mountains were once people and that Tunupa mountain and Kusku mountain were married. Tunupa at some point deserted his wife Kusku for Kusina. Kusku was left heartbroken and her tears are what formed the salt flats.

There is yet another version of the story believed by many local farmers living along the lake’s shore.

For them, they believe the mountain goddess Yana Pollera (the nearest peak to the salt flat) was involved with both Thunupa and Q’osqo.

After Yana became pregnant the male volcanoes fought over who was the father. Out of fear for the child, Yana sent the child away for protection but grew worried about its survival. She flooded the plain with milk for the baby and when it dried, the salt is all the remained.

In reality, the real reason for the formation of Salar de Uyuni is much less mystical. 40,000 years ago, Salar de Uyuni was covered by Lake Minchin due to having no drainage. The water began to collect from the surrounding mountains.

Over time the lake transformed into Paleo Lake Tauca and other smaller lakes. As the climate changed, the high salinity water began to evaporate, leaving behind the thick salt crust that we see today.

With evaporation rates of ten times the precipitation, Salar de Uyuni provides a never-ending salt supply.

What Makes Salar de Uyuni Unique?

When comparing salt-flats around the world, Bolivia’s Salar de Uyuni stands apart from other salt-flats. Several key features of Salar de Uyuni help to enhance not only its beauty but also its sheer uniqueness.

The Size of Salar de Uyuni

The sheer size and vastness of the landscape of Salar de Uyuni will leave you in awe. Salar de Uyuni is actually the world’s largest salt flat, stretching approximately 4,086 square miles (10,582 sq. km). It sits near the top of the Andes at an elevation of 3,656 meters (11,995 ft) above sea level.

The Salar de Uyuni is also extraordinarily flat and has an average altitude variation within one meter over the entire area. This is mainly due to the seasonal rains and flooding that dissolves the salt layer.

After the water evaporates, the salt flat is left level again. This cycle is what makes Salar de Uyuni one of the flattest places in the world.

Salar de Uyuni Visual Effects

Salar de Uyuni is one of the flattest places on the planet and experiencing standing in such openness is an amazing feeling. During the rainy season, December through April, the incredible experience of the salt flats is amplified by the flood water that sits on top of the Bolivian salt flats.

On still days the water turns the place into the world’s largest mirror, where it can become difficult to distinguish the water from the sky.

Photographers from all over the world flock to the salt flat to take pictures of this visual phenomenon. With the water, the landscape becomes truly flat and appears endless, excluding a few cacti.

Salar de Uyuni Mineral Content

Despite the fact that Salar de Uyuni is a salt flat, there is actually a lot more than just salt on the ground. Underneath the thick salt crust that serves as the ground of the salt flat lies a mineral-rich brine.

The salt itself contains huge amounts of sodium, potassium, and magnesium as well as borax. The brine beneath the salt is a mixture of sodium chloride, lithium chloride, and magnesium chloride.

The brine is exceptionally lithium-rich. So rich in fact that well over 40% of the world’s known lithium reserves lie beneath the Salar de Uyuni.

The Impacts of Salar de Uyuni

Salar de Uyuni has a huge impact on nearly everyone around the world, despite not being a household name.

The Natural Impact

Although Salar de Uyuni has nearly no plants or animals that call it home, there are a few that thrive there. The Hedgehog Cactus, also called the Sea-urchin Cactus, is one such plant that does very well in the environment. Other plants like shrubs Pilaya and Thola also thrive without much of a problem.

The salt flats are also home to about 80 species of birds and are the breeding ground for three species of the South American pink flamingo, one of which, James Flamingos, can only be found here thanks to the high elevation and the mineral-rich waters.

There are also horned coots, Andean geese, and Andean hillstars. The flamingos migrate here during the month of November. The salt flats are called home for the Andean fox and vicunas that are also native to the region.

The Economic Impact

Salar de Uyuni plays a huge part in economic prosperity for Bolivia. Because of the salt flats, Bolivia is one of the largest exporters of both salt and lithium in the world, as well as other minerals and agricultural goods.

Salt is and has remained a highly used commodity world-wide, and in Bolivia, around 25,000 tons of salt are extracted per year. Keep in mind Salar de Uyuni is estimated to hold about 10 billion tons of salt, and thanks to the evaporation to rainfall correlation, it is unlikely to run out any time soon.

Besides salt, one of Bolivians most important exports for the modern world is the exportation of lithium from its massive reserves. The lithium that lies in the brine beneath the surface is of a very high concentration. So, by pumping out and processing the brine, the lithium can be easily extracted.

There was a brief period that foreign companies tried to extract resources from Bolivia, however, opposition from locals forced their closure. Today locals and the Bolivian government supervise the extraction process of the country’s many resources.

Popular stops on the one-day tours are by the historic train cemetery otherwise called, “Cementerio de trenes”. This major tourist attraction was built during the end of the 19th century by British engineers.

At the time the Bolivian government believed Bolivia would flourish with a good transport system. However, the project was constantly sabotaged by the local Aymara Indians who felt it was an intrusion.

As the minerals depleted and the industry began to collapse, many of the trains were abandoned. The result has become a historic reminder of the Bolivian way of life and an attraction for lots of first-time visitors to Uyuni.
