The Grand Canyon is a steep-sided canyon carved by the Colorado River in the state of Arizona in the United States. The geological wonder is 277 miles (446 km) long, up to 18 miles (29 km) wide, and attains a depth of 6,093 feet (1,857 meters) at it’s deepest point. Recent studies suggest that the river established its course through the area roughly 5 or 6 million years ago and has continuously expanded the size of the canyon and exposed nearly two billion years of Earth’s geological history since then.
