DAY 41 (4 OF 5) – SALAR DE UYUNI, SOUTHWEST CIRCUIT DAY 4, BOLIVIA

The Salar de Uyuni (Uyuni Salt Flat) is one of the most well known geographic feature in Bolivia. About 40,000 years ago, the salt flat was part of the prehistoric Lake Minchin.  When Lake Minchin dried up, it left behind two lakes and two major salt flats, with the biggest being Salar de Uyuni.  Today, Salar de Uyuni is the biggest salt flat in the world, and is visible even  from the space.  The Salar de Uyuni stays dry for most of the year, except for the wet season when it would be flooded by water.  Every year during wet season, incoming water would bring salt from the surrounding area.  When the water evaporates, a new layer of salt would be formed.  The annual layering of salt deposit is clearly visible from the salt blocks that the locals sometimes use as building materials.  Apart from tourism, salt and rare earth extraction are some of the major industries here.  In the near future, the government is planning to expand the mining of lithium (vital component for electronic batteries) at the salt flat.
