The Red Salt Flat Ignorado.

DSC07627

This is the salt flat, Ignorado, ( Salar Ignorado), located at 4090 meters above the sea in the high Andean zone of the Region of Atacama, Chile.  (-25.498653°, -68.622165°). We took this picture in November 2013. Later in another expedition we can not see any red color. Under microscope we analyzed the water and we can not detect any colored cell. We concluded that this color corresponds a staining produced by ferrous oxides carried by the strong winds.
