Yellowstone National Park is a UNESCO World Heritage Site. In 1872 it became the first national park in the world, to preserve the large groups of geysers, hot springs, and other thermal areas, and to offer protection to the park's wildlife and environment. The park covers 3,475 square miles (8,995 sq. km), with most in the northwestern part of Wyoming. Smaller parts of the park are located in Idaho and Montana. In recent years, Boise, Idaho has been voted one of the Best Overall Towns in the Western United States by Outside Magazine, One of the 10 Best Places to Live by U.S. News and World Report, and the Ninth Hottest Midsized City or Boomtown by Inc.com. There's much more to Boise and it's 150-year-old history than just potato growing.
