Big enough to be overwhelming, still intimate enough to feel the pulse of time, Black Canyon of the Gunnison exposes you to some of the steepest cliffs, oldest rock and craggiest spires in North America. This western Colorado landmark was sculpted by the Gunnison River and the forces of weather over 2 million years. Photo of a snowy and fog-filled canyon by Judd Clark, National Park Service.
