Cottonwood Coulee and Lone Tree Coulee define the drainage patterns of this high plains landscape along the international boundary between the United States of America and Canada. Located in the northern reaches of Phillips County, the map reveals a sparsely populated terrain dominated by the Public Land Survey System grids of t37n r28e, t37n r29e, and t36n r29e. This area's characteristic isolation is evident in the limited road network, with Sunnyslope Rd serving as one of the few named thoroughfares connecting the vast township sections. The numerous small wetlands and depressions scattered across the map suggest a prairie pothole environment, critical for regional hydrology and livestock grazing in this borderland region.
