Black Canyon of the Gunnison

This picture was taken on the South Rim of the Park called Painted Wall View. The Park located just East of Montrose, Colorado is very impressive.
The Canyon walls were carved so steep due to the average drop of 96 feet per mile of the Gunnison River in the National Park. Dams were installed upstream to slow this erosion process. One can hear the roar of the River at Warner Point, the steepest point in the Canyon at 2772 feet deep.
