The Grand Canyon (Hopi:Ongtupqa; Yavapai:Wi:kaʼi:la, Navajo: Tsékooh Hatsoh, Spanish: Gran Cañón) is a steep-sidedcanyon carved by theColorado River in the state of Arizona in the United States.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 their channels through layer after layer of rock while theColorado Plateau was uplifted. While some aspects about the history of incision of the canyon are debated by geologists, several recent studies support the hypothesis that the Colorado River established its course through the area about 5 to 6 million years ago. Since that time, the Colorado River has driven the down-cutting of the tributaries and retreat of the cliffs, simultaneously deepening and widening the canyon.
