Grand Canyon National Park, Arizona

Grand Canyon National Park is one of the United States' oldest national parks and is located in Arizona. Within the park lies the Grand Canyon, a gorge of the Colorado River, considered to be one of Seven Natural Wonders of the World. The park covers 1,902 mi2 (4927 km2) of unincorporated area in Coconino County and Mohave County.
Most visitors to the park come to the South Rim, arriving on Arizona State Route 64. The Highway enters the park through the South Entrance, near Tusayan, Arizona, and heads eastward, leaving the park through the East Entrance. All park accommodations are operated by the Xanterra corporation. Park headquarters are at Grand Canyon Village, a short distance from the South Entrance, being also the center of the most popular viewpoints. Some thirty miles of the South Rim are accessible by road. A much smaller venue for tourists is found on the North Rim, accessed by Arizona State Route 67. There is no road connection between the two within Arizona except via the Navajo Bridge, near Page, Arizona, entailing a five-hour drive. Otherwise, the two rims of the Canyon are connected via Las Vegas, Nevada, and the Hoover Dam. The rest of the Grand Canyon is extremely rugged and remote, although many places are accessible by pack trail and backcountry roads.

Grand Canyon National Park became a national park in 1919. So famous is this landmark to modern Americans that it seems surprising that it took more than thirty years for it to become a national park. President Theodore Roosevelt visited the rim in 1903 and exclaimed: "The Grand Canyon fills me with awe. It is beyond comparison--beyond description; absolutely unparalleled throughout the wide world .... Let this great wonder of nature remain as it now is. Do nothing to mar its grandeur, sublimity and loveliness. You cannot improve on it. But what you can do is to keep it for your children, your children's children, and all who come after you, as the one great sight which every American should see".
Despite Roosevelt's enthusiasm and his strong interest in preserving land for public use, the Grand Canyon was not immediately designated as a national park. The first bill to create Grand Canyon National Park had been introduced in 1882 and again in 1883 and 1886 by Senator Benjamin Harrison. As President, Harrison established the Grand Canyon Forest Reserve in 1893. Theodore Roosevelt created the Grand Canyon Game Preserve by proclamation in 1906 and Grand Canyon National Monument in 1908. Senate bills to establish a national park were introduced and defeated in 1910 and 1911; the Grand Canyon National Park Act was finally signed by President Woodrow Wilson in 1919. The National Park Service, which had been established in 1916, assumed administration of the park. In 1979, UNESCO declared it as a World Heritage Site.
The Grand Canyon itself, including its extensive system of tributary canyons, is valued for the combination of large size, depth, and the exposed layering of colorful rocks dating back to Precambrian times. It was created through the incision of the Colorado River and its tributaries after the Colorado Plateau was uplifted and the Colorado River system developed along its present path.

The United States has 58 protected areas known as national parks, which are operated by the National Park Service, an agency of the Department of the Interior. National parks must be established by an act of the United States Congress. The first national park, Yellowstone, was signed into law by President Ulysses S. Grant in 1872,followed by Sequoia and Yosemite in 1890. The Organic Act of 1916 created the National Park Service "to conserve the scenery and the natural and historic objects and wildlife therein, and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations." National parks usually have a variety of natural resources over large areas. Many of them had been previously protected as National Monuments by the President under the Antiquities Act before being upgraded by Congress. Seven national parks are paired with a National Preserve, six of which are in Alaska. While administered together, they are considered as separate units and their areas are not included in the figures below. The newest national park is Great Sand Dunes, established in 2004.

Twenty-seven states have national parks, as do insular areas American Samoa and the United States Virgin Islands. Alaska and California have the most, each with eight, followed by Utah with five and Colorado with four. The largest national park is Wrangell – St. Elias, at over 8,000,000 acres (32,000 km2), followed by three more in Alaska; the smallest is Hot Springs, at less than 6,000 acres (24 km2). The total area protected by national parks is approximately 51,900,000 acres (210,000 km2), for an average of 895,000 acres (3,620 km2) but a median of only 317,000 acres (1,280 km2). The most-visited national park is Great Smoky Mountains, with over nine million visitors in 2008, followed by the Grand Canyon, with over four million. Fourteen national parks are designated World Heritage Sites.
