Grand Canyon


The Grand Canyon is one of the deepest canyons in the world with a depth of 1.8 km. The Colorado River cut through rocks to create this canyon, for billions of years, making fantastic rock shapes and coloration. The Grand Canyon is 466 km long and it ranges in width from about 160 m to 29 km. In 1908, the Grand Canyon was declared a national monument and became a national park in 1919.

View from the Point Imperial, the highest point on the North Rim at 2,683 meters. It overlooks the Painted Desert and the eastern end of Grand Canyon. Here the canyon transforms as the narrow walls of Marble Canyon. Layers of red and black Precambrian rocks, not visible at Bright Angel Point, add contrast and color. Below, the Park Clear Creek Trail and the Colorado River. It climbs through a series of switchbacks to the southeast towards Phantom Overlook (NPS photos by Michael Quinn).
