Pennington County is acounty in the northwestern part of theU.S. state ofMinnesota. As of the2020 census, the population was 13,992.[1] Itscounty seat isThief River Falls.[2]
TheWisconsin Territory was established by the federal government effective July 3, 1836, and existed until its eastern portion was granted statehood (asWisconsin) in 1848. The federal government set up the Minnesota Territory in the remaining territory, effective March 3, 1849. The newly organized territorial legislature created nine counties across the territory in October of that year. One of those original counties,Pembina, had its lower portion partitioned in 1858 by the newly organized Minnesota State legislature to createPolk County. On December 24, 1896, the legislature partitioned the northern portion of Polk to createRed Lake County. Then on November 23, 1910,[3] the northern part of Red Lake was sectioned off to create Pennington County, the penultimate Minnesota county to be created (followed byLake of the Woods in 1922). The county was named for Edmund Pennington (1848-1926), a longtime Minnesota railroad executive, who was serving as president of theMinneapolis, St. Paul, and Sault Ste. Marie Railway when the county was formed.Thief River Falls, the area's major settlement (platted in 1887), was specified as the county seat.[4]
TheRed Lake River flows westward into the county fromBeltrami County through Pennington's central portion. NearThief River Falls it is joined by theThief River, flowing southward into the county fromMarshall County. The combined flow exits Pennington County toward the south, then swings west- and northwestward as it moves to its confluence with theRed River nearGrand Forks, North Dakota. The county terrain consists of low rolling hills, lightly wooded, with all available areas devoted to agriculture.[6] The terrain slopes to the west and south,[7] with its highest point near the lower east border, at 1,186 ft (361 m) ASL.[8] The county has a total area of 618 square miles (1,600 km2), of which 617 square miles (1,600 km2) is land and 1.7 square miles (4.4 km2) (0.3%) is water.[9] Pennington is one of 17 Minnesota savanna region counties with more savanna soils than either prairie or forest soils.
