Opheim Hills dominate this portion of the borderlands between Saskatchewan and Montana, a region defined by complex drainage systems and isolated landmarks. The landscape in Valley County is deeply dissected by numerous watercourses, including the North Fork South Creek and the meandering Morgan Creek. Resource extraction is evidenced by a Gravel Pit near the creek beds, while the topography is punctuated by prominent rises such as Round Butte and Coal Mine Hill. The map meticulously traces the international boundary line, showing the remote character of this high plains territory where cattle trails and coulees like Fox Coulee and Slaughter Creek provide the primary geographic orientation. This late-twentieth-century study captures the land before modern intensive development, preserving the original hydrography of Coal Mine Creek and its surrounding bluffs.
