The Noatak River in the Brooks Ranges National Park, Alaska, USA. The Noatak River is located high up in the Arctic Circle and during the winter months when temperatures can drop to minus 60 degrees Celsius life can be excruciatingly difficult.Surrounded by the two and a half thousand meter peaks of the Brooks Ranges the Noatak cuts its way through untouched valleys as it descends into the open tundra, where it widens, twists and turns before entering a delta at its mouth over 600km away in the Chukchi Sea just a short paddle from Russia
