Jamestown to Dubois Road Trip Guide: Plains to Rockies

The drive from Jamestown, North Dakota to Dubois, Wyoming covers roughly 750 miles along US-94/US-85/I-94 and US-26. This route transects the Missouri Plateau, crosses the Badlands, and ascends the Wind River Range. A specific quirk: just west of Bismarck, the landscape abruptly shifts from flat farmland to the rolling, eroded buttes of the Little Missouri — a visual cue that you have entered the true West.
