Laguna Totota, Atacama, Chile/Colours of the Earth

This turquoise splodge in the desert is a salt lake. Minerals washed away from the ground during the seldom rainfalls and flushed into the basin, give the water this colour.  When the water evaporates in the hot desert sun, it leaves behind a layer of bright salty clay. (aerial view)
