Grand Canyon

The Grand Canyon is a canyon created and carved by the Colorado River. The canyon is located in the state of Arizona in the United States. The canyon 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. The canyon is 277 miles long, up to 18 miles (29 km) wide and holds a depth of over a mile (6,093 feet). Approximately two billion years of the geological history of Earth have been revealed as the Colorado River alongside its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. The area was previously inhabited by Native Americans, but it was explored by people such as Spanish explorer García López de Cárdenas and U.S. President Theodore Roosevelt.
