Thoeny Hills and the surrounding coulees of northern Phillips County define this high-plains landscape just south of the international border. The territory is characterized by its drainage patterns and water management features like Grog Reservoir and Cottonwood Cr, essential for ranching in this portion of the Montana-Saskatchewan frontier. Named coulees, including Kennedy Coulee, Dunham Coulee, and Voje Coulee, carve through the terrain, providing geographical landmarks in an area otherwise dominated by the public land survey grid. A network of rural routes such as Upper Frenchman Rd, Turkey Track Rd, and N Whitewater Rd connect the scattered homesteads and grazing lands, reflecting the enduring agricultural character of the region in the early 21st century.
