Chile’s Bíobío River flows northwestward from the high Cordillera of the Andes to the Pacific Ocean near Concepción, about 450 kilometers south of Santiago. The river is known globally for spectacular white-water rafting. This image shows a section of the river that skirts around Callaqui volcano in the Andes, and features the Pangue Dam and reservoir filling a narrow, meandering segment of the Bíobío River valley.
