The world's largest salt flat, Bolivia's Salar de Uyuni, is a pristine, otherworldly expanse of white. For generations, the only signs of life have been the 'saleros' who harvest salt from its radiant surface. This remote region is thrust into the future when Bolivia's leaders embark on a plan to extract a precious mineral found beneath the salt crust, and to build an infrastructure connecting the Salar to the outside world. Salero is a poetic journey through the eyes of Moises, one of the last remaining salt gatherers. Set at the dawn of the modern age in one of the most secluded places on earth, Moises' story explores how identity is formed by both tradition and progress.
