The Thoeny Hills anchor this high-plains landscape along the international boundary between Saskatchewan and Phillips County. Mapping efforts by the Geological Survey and the Department of Energy, Mines and Resources Canada emphasize the open, drainage-defined terrain of the northern borderlands during the 1980s. The region is characterized by deep coulees and intermittent water sources, such as the Grag Reservoir and the winding course of Dunham Coulee.
