West Yellowstone is a town in Gallatin County, Montana, adjacent to Yellowstone National Park. The population was 1,177 at the 2000 census. The town is served by Yellowstone Airport. It is part of the 'Bozeman Micropolitan Statistical Area'. It was founded in June 1908 when the Oregon Short Line Railroad was completed. The town's name changed several times until West Yellowstone was settled upon in 1920. At almost 7,000 feet above sea level and almost exactly halfway between the equator and north pole, West Yellowstone experiences a subarctic climate with cold, sometimes bitterly cold winters, and brief but generally warm summers.
