2020 Map of Harper Coulee

About this map

Bull Mountains topography dominates this section of Musselshell County, where a network of seasonal watercourses has carved a complex series of drainages into the high plains. The landscape is defined by its coulees, including Harper Coulee, Hay Coulee, and Road Coulee, which serve as the primary geographical markers in this semi-arid environment. Human presence is evidenced by a detailed grid of rural roads and trails, such as Hay Coulee Rd and Secor Rd, that navigate the varying elevations. The inclusion of Thompsons Water Hole and the expanse of Grassy Flat indicates the importance of specific water sources and grazing lands to the local geography. This survey provides a clear view of how land use and transit have been adapted to the deep incisions of Lamott Coulee and Goulding Cr within the larger mountain foothills.
