The Story
The Tri-State Museum traces to a June 1955 meeting after Mrs. Roy Williams of Hammond, Montana donated a collection of Western artifacts and $1,000. Local citizens formed a nonprofit and built an original cinder-block museum, expanded in 1964 and 1972. Its signature exhibit is the Johnny Spaulding Cabin, a homestead structure dating to 1876 — 13 years before South Dakota statehood. The museum moved into its current building in 2004, sharing the site with the Center of the Nation monument.
