2011 Map of Grand Portage OE N

About this map

The Pigeon River forms the winding international boundary between Canada and the United States along this northern frontier. At the turn of the 21st century, the landscape remains largely defined by its topography and the watercourse itself, which features a distinct landform labeled The Tunnel south of the border. Transport through this border region is limited to narrow corridors like County Hwy 89 and Poplar Creek Rd, which provide access to the river's edge. The 2011 survey captures the transition of the river through this remote stretch of the Arrowhead Region, illustrating the precise interface between the Thunder Bay District of Ontario and the northeastern tip of Minnesota.
