The Yellowstone Gateway Museum of Park County, formerly the Park County Museum, was founded in 1977 by a group of interested citizens. The historic North Side School was purchased with funds from the community and Park County. Since that time it has collected archives and objects pertaining to the history of Park County.
These collections cover a human time range of over 12,000 years as well as our local geology. There are approximately 50,000 items in the collections. The museum exhibits cover four interpretive categories: Pioneers, Transportation, Expeditions, and Native Cultures. Through these four exhibit halls the museum interprets the fascinating and broad history of Park County and the surrounding area, including its connection to Yellowstone National Park.
