About this map

Twin Coulee and several other drainage features define the topographical character of this Blaine County landscape. Located in north-central Montana, the area is largely defined by its township and range grid system, visible through the intersection of t37n r18e, t37n r19e, t36n r18e, and t36n r19e. The terrain is marked by seasonal watercourses such as Burrell Coulee and Corregan Coulee, which highlight the natural erosion patterns of the high plains. Human activity is sparse on this modern survey, represented primarily by rural routes like Anita Rd, which provides access through the expansive ranch lands. The map illustrates a classic western survey pattern where natural landforms and legal boundaries dictate the sparse distribution of infrastructure.
