The international boundary between the Canada / United States of America defines the southern reach of this topographic study, where the plains of North Dakota Pembina Co meet the Canadian border. The landscape is characterized by a high-density network of section lines and drainage patterns typical of the Red River Valley region, showing the precise division of agricultural lands. This 2017 survey reflects the modern rural character of the borderlands, detailing the hydrography and elevation across the flat, productive terrain of the northernmost edge of the United States. While primarily showing the American side of the line, the map provides essential context for the transnational geography of the area.
