This Hill City museum looks modest, but the staff here made a colossal discovery in finding a T-Rex named Sue in Faith, SD. They lost the battle to keep Sue (who was purchased by Chicago’s Field Museum), but they have the original skeleton of Stan the T-Rex, along with dozens of locally excavated dinosaurs, fossils of mammals, fish and reptiles, plus an impressive collection of minerals, agates and meteorites. Kids will love its Everything Prehistoric shop.
