The Grand Canyon is a steep-sided canyon carved by the Colorado River in Arizona. It is 277 miles long, up to 18 miles wide and attains a depth of over a mile. While its history goes back two billion years, the canyon was formed primarily 5 to 6 million years ago. Geologists continue to study and learn more about this big hole in the desert, where tourist continue to awe at its majesty.
The canyon area has been inhabited by Native Americans for thousands of years, but the first Europeans (Spaniards) didn't lay eyes on it until 1540. No Europeans visited the canyon again for 200 years. The Grand Canyon became an official national monument in 1908 and a national park in 1919. It is one of the most visited national parks in the US.
