Black Canyon of the Gunnison National Park

A U.S. national park in western Colorado that protects a deep, narrow canyon carved by the Gunnison River. Its steep walls and limited sunlight create a striking landscape.

Gunnison River: A river in Colorado that flows through the Black Canyon before joining the Colorado River. Its powerful flow carved the park’s defining canyon.
River incision: The deepening of a river channel as flowing water erodes its bed. Downcutting by the Gunnison River formed the canyon’s steep profile.
South Rim Road: A scenic road along the south rim of Black Canyon of the Gunnison. It connects many of the park’s best-known overlooks.
Black Canyon of the Gunnison National Monument: A former national monument established to protect Black Canyon of the Gunnison in Colorado. The monument was the park’s predecessor before its 1999 redesignation.
Black Canyon of the Gunnison: A steep, narrow canyon in western Colorado cut by the Gunnison River. This landform is the park’s central feature.
Differential erosion: Uneven wearing away of a landscape because its materials differ in resistance. Hard crystalline rock and more erodible layers weather at different rates along the canyon.
North Rim Road: A seasonal, unpaved road serving overlooks on the north rim of Black Canyon of the Gunnison. Its quieter route offers a less developed perspective on the canyon.
National Park Service: A U.S. federal agency that manages national parks and other protected sites. The agency administers the park and its visitor services.
Colorado Plateau: A high, arid region of the southwestern United States marked by uplifted sedimentary rocks and deep canyons. The park lies near the plateau’s eastern edge, where its regional geology meets the Rocky Mountains.
Colorado River: A major river of the southwestern United States that drains into the Gulf of California. The Gunnison joins it downstream, linking the park’s watershed to a much larger river system.
