About this map

Horse Pasture Coulee defines the drainage patterns of this Phillips County landscape, where deep-cut coulees and intermittent streams carve through the plains. This 1984 provisional survey shows a terrain shaped by water management and natural runoff, characterized by the presence of Black Cow Reservoir and the expansive Sun Prairie Flats. The map illustrates the hydrological relationship between major arteries like Beaver Creek and the smaller feeder systems of Miller Coulee and Smith Coulee.

Regional water movement is further detailed along the southern reaches, where Sevenmile Creek and Little Sevenmile Creek converge. These features, along with curiously named landmarks like No Name Coulee, provide a clear picture of the Montana prairie's topography before modern digital mapping. The area's character is defined by these seasonal watercourses and the livestock-supporting infrastructure essential to the local ranching economy.
