Northwest Angle
The Northwest Angle, known simply as the Angle by locals, and coextensive with Angle Township, is a pene-exclave of northern Lake of the Woods County, Minnesota. Excluding surveying errors, it is the only place in the contiguous United States north of the 49th parallel, which forms the border between the U.S. and Canada from the Northwest Angle westward to the Strait of Georgia (between the U.S. state of Washington and the Canadian province of British Columbia).
