Northwest Angle

The township of Northwest Angle in Minnesota was a geographic oddity caused by surveying errors, and is affectionately known as the Angle. It was created when map maker, John Mitchell miscalculated the source of the Mississippi being the ‘Lake of The Woods.’ The Northwest Angle's only land link is its western border with Manitoba. It's technically part of Minnesota, but with Lake of the Woods to the south, it shares no land connection with the United States. Its residents have to pass through the Canadian border twice to get to mainland US.
