2017 Map of Wagon Coulee

About this map

Fort Peck Lake and the Missouri River dominate the southern half of this landscape, marking the boundary between Valley and Garfield Counties. The terrain is characterized by a series of deep drainages feeding toward the lake, including Irishman Coulee, Wagon Coulee, and Widow Coulee. These features illustrate the complex hydrology and erosion patterns typical of the region's breaks. To the south, the isolated peak of Round Butte serves as a prominent landmark above the surrounding coulees. The northern portion is accessed via several designated routes like Harper Ridge Rd and various Forest Development Roads, reflecting the area's management within public lands and its role in grazing or recreation along the northern shores of the reservoir.
