Fodor's Expert Review Upper Musselshell Museum
A pair of 1909 sandstone buildings in the town of Harlowton, 25 miles southwest of the mountains, house the Upper Musselshell Museum. The collection primarily contains artifacts of the people who lived in, worked, and developed the land around the Upper Musselshell River. There are also fossils of bison and dinosaurs (including a full-size reproduction of "Ava," from the recently discovered species Avaceratops) in the two buildings in Harlowtown's small but picturesque commercial district.
