The Yellowstone Gateway Museum of Park County’s mission is to collect, preserve, and interpret the cultural and natural history of Park County, Montana and its relationship to Yellowstone Park for the education of everyone.  

A group of interested citizens, led by Doris and Bill Whithorn, founded the Park County Museum in 1977.  Community members and Park County purchased the historic North Side School, built in 1907, to house the museum, now known as the Yellowstone Gateway Museum of Park County.


The museum houses and preserves more than 50,000 items, including objects, photographs, manuscripts, books, audio-visual materials, and oral histories.  Collection items date from over 12,000 years ago to present. Go to “Collections”


Museum staff and volunteers interpret the fascinating history of Park County and its connection to Yellowstone National Park.  Four exhibit halls feature permanent themes: Native Cultures, Expeditions, Pioneers, and Transportation. Halls and landings feature permanent and changing exhibits, including outdoor displays.  Go To “Exhibits”
