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.
In a study published in Geology, researchers discussed their recent discovery of a vast chasm--a deep hole or fissure in the Earth--under the ice, encompassing an area of 1,081 square miles with over 683 miles of canyon. Parts of the canyon may be 0.6 miles (1 km) deep.
