Upper Musselshell Museum

The museum’s centerpiece is “Ava,” the full-size skeleton replica of a “first of its kind” Avaceratops, found in the Judith River Formation near Shawmut.

Exploring the original Upper Musselshell Museum is rather like prowling around in someone's attic or barn. This two-story limestone building, constructed in 1909, is filled with treasures that belong to the people who lived in, worked and developed the Upper Musselshell River country.
