Strange shapes in the desert. Whilst crossing the Atacama desert in Bolivia, I passed through the Salar de Uyuni salt flats. In the vastness of the white desert, strange shapes were cut into the floor. Blocks of salt were extracted and left in the sun to dry before being removed and sold. The remaining angular shapes were gradually filled with the water that lingered beneath the surface.
In the wet season, the floor of the salt flats becomes flooded and the looks like an impossibly huge mirror, making it hard to know which is heaven and earth.
