Sweet Grass Hills rise sharply above the high plains of Northern Montana in this mid-century survey, anchoring a landscape defined by the intersection of ranching and the energy industry. The northern border with Canada is punctuated by ports of entry, while the vast southern reaches are shaped by the Marias River and the massive Tiber Reservoir, held by the Tiber Dam. The region's economy is etched into the terrain through extensive oil and gas wells and gas and oil fields that sprawl near Kevin and Sunburst.
