"In Chile, when the sun rises, it had to climb hills, walls and tops before reaching the last stone of the Cordillera. In my country, the Cordillera is everywhere. But for the Chilean citizens, it is an unknown territory. After going North for Nostalgia for the Light and South for The Pearl Button, I now feel ready to shoot this immense spine to explore its mysteries, powerful revelations of Chile’s past and present history." Patricio Guzmán
