The international border between the Canada / United States of America and the tri-state convergence of North Dakota and Minnesota defines this 2017 survey. The landscape is dominated by the winding path of a major river system that weaves across the 49th parallel, creating a complex series of oxbows and floodplains. Along the southern margin, the junction of Pembina Co North Dakota Minnesota Kittson Co highlights the precise meeting point of two states and two counties at the national frontier. This map captures the intricate drainage patterns and local survey boundaries of the Red River Valley region, showing how the natural hydrology ignores the straight-line political divisions of Kittson Co Minnesota and its neighbors.
