Deep in the heart of Chile's Patagonia region flow two of the world's purest rivers, the Baker and Pascua. Fed by vast glacial systems, these untouched rivers drive biodiversity in rainforests, estuaries and marine ecosystems. They are also the life source for Patagonia's most tenacious residents: the Gauchos, the iconic South American cowboys who endure relentless winds and long winters on remote ranches in these river valleys.
