About this map

Fort Peck Lake dominates the southern landscape of this Valley County region, where the intricate, flooded fingers of the reservoir reach into the prairie. The terrain is defined by a series of drainage features, most notably Middle Eighth Coulee, which carves through the central portion of the map alongside Upper Eighth Coulee and Lower Eighth Coulee. These watercourses are flanked by prominent elevations such as Middle Eighth Ridge and Seventh Ridge, illustrating the complex erosion patterns of the Missouri River breaks.

Human activity is concentrated at isolated ranching outposts like Browning Ranch and Stebley Ranch, connected by the unpaved Stebley Rd. For genealogists and local historians, Graveyard Hill stands as a significant landmark above the lake. Numerous small-scale water management features, including Magruder Reservoir, Tiger Reservoir, and Stebley Reservoir, dot the landscape, highlighting the importance of water storage for livestock and ranching operations in this semi-arid environment.
