Montana (/mɒnˈtænə/ (listen)) is a state in the Northwestern United States. It is bordered by the Canadian provinces of Alberta, British Columbia, and Saskatchewan to the north; Idaho to the west; North Dakota and South Dakota to the east; and Wyoming to the south. It is the fourth-largest state by area, the eighth-least populous state, and the third-least densely populated state.
The western half of Montana contains numerous mountain ranges, while the eastern half is characterized by western prairie terrain and badlands, with more (albeit smaller) mountain ranges found throughout the state. In all, 77 named ranges are part of the Rocky Mountains.
Montana has no official nickname but several unofficial ones, most notably “Big Sky Country”, “The Treasure State”, “Land of the Shining Mountains”, and “The Last Best Place“. The economy is primarily based on agriculture, including ranching and cereal grain farming. Other significant economic resources include oil, gas, coal, mining, and lumber.
The health care, service, and government sectors also are significant to the state’s economy. Montana’s fastest-growing sector is tourism; nearly 13 million annual tourists visit Glacier National Park, Yellowstone National Park, Beartooth Highway, Flathead Lake, Big Sky Resort, and other attractions.
