In Hamilton, Montana, the Ravalli County Museum preserves the historical and cultural heritage of the Bitter Root Valley through exhibits, archives, and community events. Founded in 1955 in the town’s old train depot, it moved after local advocates saved the 1900 Ravalli County Courthouse from demolition and repurposed it as the museum. Its galleries explore valley communities, Native peoples, natural history, art, homesteading, agriculture, military service, and domestic life, with notable exhibits on the 1805 meeting of the Bitterroot Salish with Lewis and Clark and on pioneer photographer Bertie Lord. The museum also supports research and hosts annual programs tied to local traditions and preservation.
