The world's largest salt desert - Uyuni Salt Flat - falls within Daniel Campos Province in Potosí in southwest Bolivia, near the crest of the Andes. Salt deserts, commonly known as salt flats or salt pans, are vast expanses of land covered by salt crystals. Salt deserts are often characterised by a stark, otherworldly beauty. They are formed in arid or semi-arid regions where the climate is too dry to support vegetation, and where water flows into the region and then evaporates, leaving behind salt deposits. These deposits build up over time, forming thick layers of salt that cover the land. They are home to a unique array of flora and fauna adapted to the harsh saline conditions, such as salt-tolerant plants and animals like flamingos and brine shrimp.
