2 Best Sights in Fort Peck, Billings, Little Big Horn, and the Montana Plains

The 18,000-square-foot Fort Peck Interpretive Center features interpretive displays recounting the history and significance of the dam's construction, wildlife of the lower river and Missouri River Breaks. You'll find one of the most striking life-size dinosaur displays in the West, a reproduction of Peck's Rex, a tyrannosaurus Rex unearthed near Fort Peck, as well as other local dinosaur discoveries. The center also features the largest aquariums in Montana, filled with the native and introduced fish species of Fort Peck Reservoir and the Missouri River. Guided tours of the dam and its power plants are available April through October.

At the peak of dam construction, nearly 11,000 workers lived in Fort Peck; together with their families, they made up a thriving population center of 50,000. To help keep the populace entertained, the Army Corps of Engineers built a movie house in 1934. It was supposed to be a temporary structure, but instead it eventually became the Fort Peck Summer Theatre. The chalet-style building is a venue for live entertainment on weekend nights in summer.
