The Yellowstone is the longest undammed river in the contiguous 48 states, flowing with a wildness that is both violent and vital to the creatures that are drawn to its banks. From Yellowstone Lake, North America’s largest high-elevation body of water, to the Missouri River, follow its nearly 700-mile journey over falls and through canyons into America’s heartland. See how Yellowstone’s bison, otters, coyotes, and thrill-seekers adapt to—and thrive in—these wild, untamed waters.
