About this map

Charles M Russell National Wildlife Range dominates this river-carved landscape, reflecting a 1970s view of the protected Missouri River breaks. The topography is defined by the expansive Fort Peck Lake, formed by the damming of the Missouri River, which creates a jagged, flooded shoreline through the center of the sheet. This boundary separates Valley and Garfield Counties, where the water has inundated deep ravines like Irishman Coulee and Wagon Coulee.

Human presence is sparse and dictated by the terrain, marked by remote outposts such as Faranuf Ranch and the locality of Gibson. A Jeep Trail provides one of the few passages through the dissected plateau north of the lake. The map documents numerous named drainage features, including Carpenter Creek and Cabin Coulee, illustrating the intricate erosion patterns of the northern plains before they meet the reservoir’s edge at the Fort Peck Boundary Indefinite.
