Wyoming is a state in the mountain region of the Western United States. It is bordered on the north by Montana, on the east by South Dakota and Nebraska, on the south by Colorado, on the southwest by Utah, and on the west by Idaho. Cheyenne is the capital and the most populous city in Wyoming.
The western two-thirds of the state is covered mostly with the mountain ranges and rangelands in the foothills of the eastern Rocky Mountains, while the eastern third of the state is high elevation prairie known as the High Plains. Its famed Yellowstone National Park, a nearly 3,500-sq.-mile wilderness recreation area, is home to hundreds of animal species, dramatic canyons and alpine rivers.
