| | Grand Canyon National Park - Wikipedia, the free encyclopedia |
 | | The area around the Grand Canyon became a national monument on January 11, 1908 and was designated national park on February 26, 1919. |
 | | Within the park lies the Grand Canyon, a gorge of the Colorado River, considered to be one of the major natural wonders of the world. |
 | | The Grand Canyon itself—really an extensive system of tributary canyons— is neither the largest or deepest canyon in the world, but is valued for the combination of large size, depth, and the exposed layering of colorful rocks dating back to Precambrian times. |
