2011 Map of Angle Inlet SW OE N

About this map

The international border between the Canada and the United States defines the southern boundary of this specific map area, highlighting one of the most unique geographic anomalies in North America. Situated within the Lake of the Woods region, the map documents a portion of the Northwest Angle, where the Northwest Angle Inlet serves as a critical waterway. Produced by the U.S. Geological Survey in 2011, this sheet focuses on the aquatic and geopolitical interface where the Minnesota border meets the Canadian province of Ontario. The lack of interior labels reflects the primarily open-water nature of this particular quadrant, making it an essential reference for understanding the precise maritime boundaries and coordinates that isolate this American exclave from the contiguous United States.
