Black Canyon of the Gunnison National Park
Black Canyon of the Gunnison National Park is in western Colorado. It surrounds part of a deep, steep-walled gorge carved through Precambrian rock by the Gunnison River. Roads and trails along the north and south rims have views of the Black Canyon's dramatic drops and the striated Painted Wall cliff. The winding East Portal Road descends to the river. Wildlife includes mule deer, elk and golden eagles.
