The Northwest Angle, known simply as the Angle by locals, and coextensive with Angle Township, is a part of northern Lake of the Woods County, Minnesota. The population was 119 at the 2010 census. Except for minor surveying errors, it is the only place in the United States outside Alaska that is north of the 49th parallel, which forms the international border from the Angle west to Washington State. It is one of only six non-island locations in the 48 contiguous states that are exclaves of the U.S. although not directly connected to them by land. At 49.22° north latitude, it is the northernmost township in Minnesota and the northernmost point in the contiguous 48 states. The unincorporated communities of Angle Inlet and Penasse are located in the Northwest Angle.
Although the Angle is listed as one of several distinct regions of Minnesota, its total population was only 152 at the 2000 census. The land is mostly forest and the area is mostly water.
The initial establishment of Angle Township being in the United States was due to a map-maker's error. Benjamin Franklin and British representatives established the initial U.S. and Canadian borders in the Treaty of Paris in 1783 from a map that mis-represented the source of the Mississippi River.
The Treaty of Paris, concluded between the United States and Great Britain at the end of the American Revolutionary War, stated that the boundary between U.S. territory and the British possessions to the north would run "...through the Lake of the Woods to the northwestern-most point thereof, and from thence on a due west course to the river Mississippi..."
The parties did not suspect that the source of the Mississippi River, Lake Itasca (then unknown to European explorers), was south of that point. The entire Mississippi was too far south to be intersected by a line running west from the Lake of the Woods. The parties had used the Mitchell Map during the treaty negotiations; that map showed the Mississippi extending far to the north. In the Anglo-American Convention of 1818, the error was corrected by having the boundary run directly from the northwest point of the lake to the 49th parallel and then westward along it.
When a survey team led by David Thompson finally located the northwestern-most point of the lake and surveyed this north-south line, it was found to intersect other bays of the lake and therefore to form the boundary of a section of U.S. territory to its east, now known as the Northwest Angle.
According to the United States Census Bureau, Angle Township has a total area of 596.3 square miles (1,544.5 km2) of which 123.09 square miles (318.81 km2) is land and 473.2 square miles (1,225.7 km2) (79.36%) is water. The land includes several islands, including Oak Island, and two small capes that are below (south of) the 49th parallel north in the extreme southwest part of the township, south of the southeast corner of Manitoba, and not far from the northeast corner of Roseau County. Of the 2000 census population of 152, there were 118 living on the mainland, and 34 persons on the islands in Lake of the Woods. All of the populated islands are north of the 49th parallel.
The mainland portion of the township north of the 49th parallel has an area of 116.632 square miles (302.08 km2). The total land area of all islands is 6.303 square miles (16.32 km2), and the two capes total 100 acres (0.16 sq mi; 40.47 ha). The township has the last one-room public school in the state.
Elm Point, in Lake of the Woods County, is a small cape southwest of the Northwest Angle. It borders Canada and is, together with a similar smaller cape to the west, separated by land from the continental United States.
The Angle is accessible from the rest of Minnesota by one of two ways:
- The Angle can be reached without crossing the international border by crossing the Lake of the Woods by boat when the lake is free of ice, by ice road in the winter or by flying over it in a plane. No automobile ferries currently operate on the lake, so vehicles coming from the rest of Minnesota can reach the Angle without crossing the border only in winter. While the ice is forming in late autumn and breaking up in the spring, the lake's surface cannot be crossed safely – at these times domestic access to the Angle is possible only by air.
- To reach the Angle by land, travelers take Minnesota State Highway 313N (Warroad, Minnesota to Sprague, Manitoba) across the border into Manitoba, Canada, connecting to Provincial Road 12 in Manitoba at the border, then to Provincial Road 308 Manitoba, to Provincial Road 525, then finally crossing back into the United States in the Northwest Angle south of rural Angle Inlet, Minnesota (Angle Inlet Township). The distance from Warroad or Roseau to the Angle proper is approximately 63 miles through Minnesota and Manitoba back to the Angle's U.S. border. It is approximately 10 miles from the actual border (intersection of Manitoba #525 and NWA Road Dawson) to the rural developments of the Northwest Angle.
The border crossing (image) is unstaffed. Travelers using the single gravel road in and out of the Angle are expected to use a telephone at Jim's Corner, Youngs Bay Marina or Carlsons Landing to contact Canadian or U.S. Customs and make their declarations.
Political issues 
Because of laws restricting fishing, some residents of the Northwest Angle suggested leaving the United States and joining Canada in 1997. The following year, U.S. Representative Collin Peterson of Minnesota proposed a constitutional amendment to allow the residents of the Northwest Angle, which is part of his district, to vote on seceding from the United States and joining Canada. This angered the leaders of Red Lake Indian Reservation, which holds most of the Northwest Angle's land.
In 1997, in order to change what were considered unequal fishing regulations between the U.S. and Canada, Angle resident Gary Dietzler utilized this cartographical mishap to implement a mock secession from the United States, going so far as to get a bill issued by their Congressman Collin Peterson (D) in the U.S. House of Representatives. The mock secession succeeded in getting fishing regulations better synchronized across these international (fresh) waters.
Peterson said he introduced the amendment to bring equity (under NAFTA) to alleged irregularities in the ways differing nationalities were treated on the Canadian portion of Lake of the Woods. US fishermen were not allowed to keep any gamefish caught in Ontario, unless they were staying at Canadian lodging facilities. This was later repealed by Ontario officials once a court action was initiated.
As of the census of 2000, there were 152 people, 71 households, and 48 families residing in the Angle. The population density was 1.2/mi2 (0.5/km2). There were 272 housing units at an average density of 2.2/mi2 (0.9/km2). The racial makeup of the township was 99.34% White. Hispanic or Latino of any race were 0.66% of the population.
There were 71 households out of which 14.1% had children under the age of 18 living with them, 63.4% were married couples living together, 1.4% had a female householder with no husband present, and 31.0% were non-families. 23.9% of all households were made up of individuals and 5.6% had someone living alone who was 65 years of age or older. The average household size was 2.14 and the average family size was 2.53.
In the Angle the population was spread out with 14.5% under the age of 18, 3.3% from 18 to 24, 21.1% from 25 to 44, 48.7% from 45 to 64, and 12.5% who were 65 years of age or older. The median age was 50 years. For every 100 females there were 120.3 males. For every 100 females age 18 and over, there were 124.1 males.
The median income for a household in the township was $28,500, and the median income for a family was $31,250. Males had a median income of $28,500 versus $21,250 for females. The per capita income for the township was $13,932. About 13.3% of families and 12.3% of the population were below the poverty line, including none of those under the age of 18 or 65 and older.
