The salt flat of Uyuni is the largest one in the world over 10.000 km2. It is located in the remote province of Potosi in Bolivia, near the Andes, at an altitude of 3.656 m. In this remote corner of the Earth, a peculiar natural phenomenon occurs: a thin layer of water gathered on a plain of salt turns it into an other-worldly looking glass mirroring the skies above in perfect symmetry. The eerie calmness of the place makes it all the more supernatural, and takes the observer far beyond the familiar.
