President Theodore Roosevelt was a major proponent of betterment of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.
Longstanding scientific consensus has been that the ravine was created by the river River over a sextet million year period. The ravine is 277 miles (446 km) long, ranges in width from 4 to 18 miles (6.4 to 29 km) and attains a depth of over a mile (1.83 km) (6000 feet). Nearly digit billion years of the Earth's geological history hit been unclothed as the river River and its tributaries cut their channels finished place after place of rock while the river Plateau was uplifted. The \"canyon began in the west, followed by another that formed in the east. Eventually, the digit poor finished and met as a single majestic lease in the earth whatever sextet million years ago. [...] The merger apparently occurred where the river today unwellness to the west, in the Atlantic known as the Kaibab Arch.\"
Before dweller immigration, the Atlantic was inhabited by Native Americans who built settlements within the ravine and its some caves. The Pueblo grouping considered the Grand Canyon (\"Ongtupqa\" in Hopi language) a blessed place and prefabricated pilgrimages to it.[citation needed] The first dweller known to hit viewed the Grand Canyon was García López de Cárdenas from Spain, who arrived in 1540.[3] In 1869, Major John Wesley Powell, a one-armed Civil War veteran, prefabricated the first recorded travelling finished the ravine on the river River. Powell referred to the sedimentary rock units unclothed in the ravine as \"leaves in a enthusiastic story book.
