Black Canyon of the Gunnison National Park
Black Canyon of the Gunnison National Park contains 12 miles of the 48-mile long Black Canyon of the Gunnison River. The national park itself contains the deepest and most dramatic section of the canyon. The canyon's name owes itself to the fact that parts of the gorge only receive 33 minutes of sunlight a day. Several canyons in the American west are longer and some deeper, but none combines the depth, sheerness, narrowness, and darkness of the Black Canyon.
