# St. Louis County, Minnesota

St. Louis County is a county in the Arrowhead Region of Minnesota. As of the 2020 census, the population was 200,231. Its county seat is Duluth. It is the largest county in Minnesota by land area, and the largest in the United States by total area east of the Mississippi River. St. Louis County is included in the Duluth, MN–Superior, WI Metropolitan Statistical Area.
Major industries include pulpwood production and tourism. Open pit mining of taconite and processing it into high grade iron ore remains an important part of the economy of the Iron Range and is directly tied to shipping in the twin ports of Duluth and Superior. Parts of the federally recognized Bois Forte and Fond du Lac Indian reservations are in the county.

## History

This area was long inhabited by Algonquian-speaking tribes: the Ojibwe (Chippewa), Ottawa and Potawatomi peoples were loosely affiliated in the Council of Three Fires. As American settlers entered the territory, the Native Americans were pushed to outer areas.
The Minnesota Legislature established St. Louis County on February 20, 1855, as Doty County, and changed its name to Newton County on March 3, 1855. It originally consisted of the area east and south of the St. Louis River, while the area east of the Vermilion River and north of the St. Louis River was part of Superior County. Superior County was renamed St. Louis County.
On March 1, 1856, that St. Louis County was renamed as Lake County. Newton County was renamed as St. Louis County and had that eastern area added to it; it was also expanded westward by incorporating parts of Itasca County, which then also included most of Carlton County. On May 23, 1857, St. Louis County took its current shape when Carlton County was formed from parts of St. Louis and Pine counties.

## Geography

According to the United States Census Bureau, the county has a total area of 6,860 square miles (17,800 km$^2$), of which 6,247 square miles (16,180 km$^2$) is land and 612 square miles (1,590 km$^2$) (8.9%) is water. It is the largest county in Minnesota and the largest (by total area) in the United States east of the Mississippi River. St. Louis County is the only county in the United States which has a coastline and borders both another country and another state.
Voyageurs National Park, established in 1975, is located in its northwestern corner, on the south shore of Rainy Lake on the Canada–US border; it is popular with water enthusiasts and fishers. The county includes parts of Superior National Forest, established in 1909, and the Boundary Waters Canoe Area Wilderness on the border, established in 1978. The BWCAW is a 1,090,000-acre (4,400 km$^2$) wilderness area designated for fishing, camping, hiking, and canoeing, and is one of the most visited wilderness areas in the United States. St. Louis County has more than 500 lakes. The largest lakes are Pelican and Vermilion.
The "Hill of Three Waters" on the Laurentian Divide lies northeast of Hibbing. Rainfall on this hill runs to three watersheds: Hudson Bay to the north, the Gulf of Saint Lawrence to the east (via Lake Superior), or the Gulf of Mexico to the south and west (via the Mississippi River). The county is drained by the St. Louis, Vermilion, and other rivers.
Duluth on Lake Superior is one of the most important fresh-water ports in the United States.
The county encompasses part of the Iron Range. It has had a significant taconite mining industry, with active mines located in Hibbing, Mountain Iron, Eveleth, Virginia, and Babbitt, in addition to Keewatin in Itasca County.

## Climate and weather

The county has a humid continental climate (Köppen Dfb), slightly moderated by its proximity to Lake Superior. Winters are long, snowy, and very cold, normally seeing maximum temperatures remaining below 32 °F (0 °C) on 106 days. Due to global warming, in January 2019 Tracy Twine, professor at the University of Minnesota's Department of Soil, Water and Climate, said "we just don't expect temperatures to be below 10 degrees Fahrenheit in Duluth anymore." Public schools and other government offices shut down on January 29–30, 2019 because of wind chills of −70 °F or −56.7 °C. This apparent anomaly was attributed to changes in the global jet stream due to the climate change.

In 2007, St. Louis County considered doing a study about dividing into two counties, but the proposal was not acted on.
This county is one of the most reliably Democratic counties in the state, as no Republican or Independent candidate has won the county in a statewide election since 1992. The only time a Democrat obtained less than 50% of the vote was in 1998, when Jesse Ventura of the Reform ticket won statewide; some 24% of the county voted for him. Since 1992, the only time when a Republican obtained more than 34% of the vote was in the elections of 1994 (the year of the Republican Revolution) when the incumbent Independent-Republican governor won the statewide vote by a landslide of more than 60%, and when the Independent-Republican senatorial candidate won election with 49% statewide, both of which are rare occurrences in Minnesota.

### Presidential elections

St. Louis County has long been one of the strongest Democratic bastions in the state outside of the Twin Cities. The Democrats have carried the county for 24 consecutive presidential elections; the last Republican candidate to carry the county was Herbert Hoover in 1928, before the Great Depression. In recent elections, Republicans have received about 1/3rd of the county's vote. In 2016, Donald Trump earned 39.7% of the county's vote, while the Democratic vote deteriorated to 51.4% (the lowest percentage since 1932); according to exit polls, this was due to residents' concerns about the decline of mining and forestry in the county. This was the closest that a Republican had come to winning the county since 1932. In 2020, Trump became the first Republican since Herbert Hoover to get more than 40% of the vote in St. Louis County, but Joe Biden bolstered the Democratic margin of victory from 11.7% to 15.6%.
