The Canada United States international border defines the northern edge of this high-plains landscape, where the rural economy of the mid-20th century relied on coal extraction and rail transport. The southern portion of the quadrangle is dominated by industrial activity within Koalfield, characterized by an expansive Strip Mine and the logistics of the Burlington Soo Line. Small industrial settlements like Atcoal and Strange Siding appear as critical transit points for the region's natural resources.
