2014 Map of Sullivan Coulee

About this map

The Redwater River and its seasonal drainage network define this expanse of the eastern Montana plains along the border of McCone and Richland counties. The landscape is carved by prominent natural depressions such as Sullivan Coulee, Milne Coulee, and Hubbard Coulee, which serve as the primary topographic markers in an area otherwise characterized by high-plateau cattle country and dry-land farming. A sense of early settlement persists through labels like Grandview Cem, located on a high point near the junction of Co Road 142 and Co Road 305. The township and range lines of the Public Land Survey System organize the territory into a neat grid, with secondary routes like MT-201 and Sunnyside Rd providing the only modern infrastructure through the drainages of Muskrat Cr and E Redwater Cr.
