The Magnificent Nahanni extols the natural wonders of the South Nahanni Valley—its untamed waters, high, glaciated mountains, colourful tufa mounds, great falls, deep canyons, caves and karst, extensive forests, alpine tundra, and diverse wildlife, including Dall's sheep, caribou, wolf, and grizzly bear. It is also the story of cooperative efforts to conserve the area while maintaining Indigenous hunting and fishing rights.
