The Grand Canyon is a steep-sided canyon carved by the Colorado River. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.
The Grand Canyon is 277 miles long, up to 18 miles wide and attains a depth of over a mile. Nearly two billion years of Earth's geological history has been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. There are no words to describe it's stunning beauty!
