The Grand Canyon (Hopi: Ongtupqa; Yavapai: Wi:kaʼi:la, Spanish: Gran Cañón) is a steep-sided canyon carved by the Colorado River in the U.S. state of Arizona. It is contained within and managed by Grand Canyon National Park, the Kaibab National Forest, Grand Canyon-Parashant National Monument, the Hualapai Tribal Nation, the Havasupai people and the Navajo Nation. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.
The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters). Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut channels through the rock while the Colorado Plateau was uplifted. Evidence suggests this began 17 million years ago.
For thousands of years, the area has been continuously inhabited by Native Americans, including the Pueblos who considered it a holy site for pilgrimages. The first European known to have arrived there was García López de Cárdenas from Spain in 1540.
Grand Canyon in "Down in the Bottomlands"
There was a notable geological depression in the Empire of Stekia. It was the largest such feature in that continent, but paled in comparison to the Bottomlands of the Great Continent across the Western Ocean.
