History

Roundup served as a place for cattlemen to “round up” their cattle along the Musselshell River. It was the trailhead in the Great Montana Centennial Cattle Drive and now drives happen annually.

The post office opened in 1883. In 1907, the Milwaukee Road reached Roundup.

The area has coal mines, which combined with the agriculture, maintained the economy of the town. The Musselshell Valley Historical Museum captures the coal history as well as fossils and Indian artifacts.

From Hell to Breakfast in Old Montana, by Leland Blanchard, tells the story of pioneers who lived and worked in Roundup in the early 1900s.
