Alfredo Morales bears on his face the toll of the relentless cold and searing sun that hangs almost year-round over Antofagasta de la Sierra, a town on the high plains of Catamarca province, northern Argentina. The 55-year-old, an activist with Atacameños del Altiplano, a local Indigenous organisation, is driving his truck out to the nearby Salar del Hombre Muerto salt flat.
