Landscape[edit] The Black Canyon (contained in the borders of the park) is a very deep gorge containing sheer cliffs up to heights of 2250 feet (685 m). The canyon was carved by the Gunnison River, located at the very bottom of the canyon.
Black Mountain is located in Cave Creek, Arizona, just north of Scottsdale, near Phoenix. A less visited Phoenix area mountain, this is the place to go when you can't find parking at Camelback or Piestewa Peak. It is just a walk up that takes 1 to 1.5 hours. At the top you'll see great views of the area and the surrounding mountains. It's about an 1100 ft elevation gain and 2.2 miles round trip.
