Salt Lake

The Chilean salt lake is very different from the Bolivian one which is smoother - here the chloride crusts can reach up to 70 cms high. They have been formed by the accumulation of crystals produced by evaporation of underground saline waters. Minerals are extracted and exported from these salt flats : magnesium, borax and 50% of the world's supply of lithium.
