About this map

The Missouri River corridor dominates this 1980s landscape, illustrating the intricate shoreline of Fort Peck Lake as it winds through the Charles M Russell National Wildlife Refuge. The map details a complex system of water-cut drainages including Sutherland Creek and Bighorn Creek, which feed into the primary river channel. This era of the reservoir is marked by numerous bays and inlets such as Snow Creek Bay and Hell Creek Bay, reflecting the flooded Missouri River Breaks topography.

High ground is defined by features like Harper Ridge and the eponymous Peterson Point, while the lower terrain is etched with numerous coulees, including Coyote Coulee and Rattlesnake Coulee. A lone Navigation Marker serves as a reminder of the lake's importance for transit. The boundary between Valley and Garfield Counties follows the original riverbed, cutting through the center of the modern reservoir.
