Assiniboine Creek winds through this expanse of northern Montana, where the terrain is marked by intermittent watercourses and technical survey markings. This mid-1980s provisional map serves as a primary record of the drainage patterns in this portion of Phillips County, detailing how moisture moves across the land through features like Wilson Coulee in the northwest corner. The land is characterized by numerous small depressions and basins, suggesting a landscape shaped by seasonal water movement and subtle elevation changes across the plains. Primarily a study of natural geography and hydrology, the map provides precise data for land management and environmental research in a region where water sources like these creeks are central to the landscape's identity.
