2024 Map of Wagon Coulee

About this map

Charles M Russell National Wildlife Refuge dominates this section of the Missouri Breaks, where the Missouri River widens into the expansive Fort Peck Lake. This landscape is defined by the complex drainages of the Garfield and Valley county line, featuring deep-cut channels such as Wagon Coulee, Irishman Coulee, and Widow Coulee. The topography rises sharply from the water to landmarks like Round Butte and the high ground of Harper Ridge. While the terrain is primarily managed for conservation, a sparse network of access routes like CMR 508 and RD 504 provides the only passage through this intricate breaks country. The map illustrates the contemporary shoreline of the reservoir and the extensive protected lands that preserve the character of this river corridor.
