2024 Map of Antelope Coulee NW

About this map

Suphellen Reservoir serves as a primary water landmark in this northern Toole County landscape, where the terrain is defined by a series of drainage systems known locally as coulees. These topographical features, including Picadilly Coulee and Fifteenmile Coulee, reveal the complex natural irrigation and erosion patterns characteristic of the Montana plains. The map details a strictly grid-based rural road network named for local figures or families, such as Woldtvedt Rd, Sauby Rd, and Gus Blaze Rd. These roads reflect the continued agricultural division of the land into townships like t34n r1w. The intersection of natural landmarks like Antelope Coulee with these established county roads provides a clear picture of how modern rural life is structured around the physical geography of the High Plains.
