1984 Map of Gustin Coulee

About this map

Gustin Coulee dominates this northern Phillips County landscape, where the high plains of Montana meet the Saskatchewan border. This mid-1980s topographical study illustrates a region defined by critical water management in an arid environment, featuring a series of named catchments such as 3 Way No 2 Reservoir and Waterfowl Reservoir. These features, along with Walchuk Spring, suggest a reliance on these localized water sources for ranching or conservation during the late twentieth century. The boundary line between the United States and Canada is clearly delineated along the northern edge, marking the international extent of this prairie terrain. Small bodies of water like Pea Lake and Palea Reservoir are scattered throughout the quadrangle, highlighting the intricate drainage patterns that feed into the coulee system.
