Zion National Park

Zion National Park is located in the Southwestern United States, near Springdale, Utah. A prominent feature of the 229-square-mile park is Zion Canyon, which is 15 miles long and up to half a mile deep, cut through the reddish and tan-colored Navajo Sandstone by the North Fork of the Virgin River. The lowest elevation is 3,666 ft at Coalpits Wash and the highest elevation is 8,726 ft at Horse Ranch Mountain. Located at the junction of the Colorado Plateau, Great Basin, and Mojave Desert regions, the park's unique geography and variety of life zones allow for unusual plant and animal diversity. Numerous plant species as well as 289 species of birds, 75 mammals, and 32 reptiles inhabit the park's four life zones: desert, riparian, woodland, and coniferous forest. Zion National Park includes mountains, canyons, buttes, mesas, monoliths, rivers, slot canyons, and natural arches. Human habitation of the area started about 8,000 years ago with small family groups of Native Americans; the semi-nomadic Basketmaker Anasazi stem from one of these groups. In turn, the Virgin Anasazi culture developed as the Basketmakers settled in permanent communities.
