Every local museum should show Grandma’s washing machine, a license plate collection and a rural school classroom. Fall River Pioneer Museum checks all those boxes — and then it deviates from the norm with exhibits that won’t be found anywhere else. For example — a century ago, paleontologists and fossil hunters came to this area and carted off all the surface fossils they could carry, including very rare cycad specimens that locals called petrified pineapples. The museum dedicates a room to the travesty, with photographs and correspondence, several cycad fossils and a living plant that shows what the cycads were like 100 million years ago. Pioneer Museum stands high over River Street, in a three-story sandstone that was built in 1891 as a schoolhouse. The 25 exhibit rooms offer colorful and deep perspectives of the Southern Black Hills.
