Minnesota (help·info) (pronounced /ˌmɪnɨˈsoʊtə/)[2] is a state located in the Midwestern region of the United States. The 12th-largest state by area in the U.S., it is the 21st most populous, with just over five million residents. Minnesota was carved out of the eastern half of the Minnesota Territory and admitted to the Union as the 32nd state on May 11, 1858. The state is known as the "Land of 10,000 Lakes", and those lakes and the other waters for which the state is named, together with state and national forests and parks, offer residents and tourists a variety of outdoor recreational opportunities.
Nearly 60% of Minnesota's residents live in the Minneapolis-Saint Paul metropolitan area known as the Twin Cities, the center of transportation, business, and industry, and home to an internationally known arts community. The remainder of the state, often referred to as "Greater Minnesota" or "Outstate Minnesota", consists of western prairies now given over to intensive agriculture; eastern deciduous forests, also heavily farmed and settled; and the less-populated northern boreal forest. While the state's residents are primarily white and of Northern European ancestry, substantial influxes of African, Asian, and Latin American immigrants have joined the descendants of European immigrants and of the original Native American inhabitants.
The extremes of the climate contrast with the moderation of Minnesota’s people. The state is known for its moderate-to-progressive politics and social policies, its civic involvement, and high voter turnout. It ranks among the healthiest states by a number of measures, and has one of the most highly educated and literate populations.
Etymology
The word Minnesota comes from the Dakota language name for the Minnesota River: Mnisota. The root Mni (also spelled mini or minne) means "water". Mnisota can be translated as sky-tinted water or somewhat clouded water.[3][4] Native Americans demonstrated the name to early settlers by dropping milk into water and calling it mnisota.[3] Many locations in the state have similar names, such as Minnehaha Falls ("waterfall", not "laughing waters" as is commonly thought), Minneiska ("white water"), Minnetonka ("big water"), Minnetrista ("crooked water"), and Minneapolis, which is a combination of mni and polis, the Greek word for "city."[5]
Geography
Minnesota, showing roads and major bodies of water
Minnesota is the northernmost state outside of Alaska; its isolated Northwest Angle in Lake of the Woods is the only part of the 48 contiguous states lying north of the 49th Parallel. Minnesota is in the U.S. region known as the Upper Midwest. The state shares a Lake Superior water border with Michigan and Wisconsin on the northeast; the remainder of the eastern border is with Wisconsin. Iowa is to the south, North Dakota and South Dakota are west, and the Canadian provinces of Ontario and Manitoba are north. With 87,014 square miles (225,365 km²), or approximately 2.25% of the United States,[6] Minnesota is the 12th largest state.[7]
Geology and terrain

Minnesota contains some of the oldest rocks found on earth, gneisses some 3.6 billion years old, or 80% as old as the planet.[8][9] About 2.7 billion years ago, basaltic lava poured out of cracks in the floor of the primordial ocean; the remains of this volcanic rock formed the Canadian Shield in northeast Minnesota.[8][10] The roots of these volcanic mountains and the action of Precambrian seas formed the Iron Range of northern Minnesota. Following a period of volcanism 1.1 billion years ago, Minnesota's geological activity has been more subdued, with no volcanism or mountain formation, but with repeated incursions of the sea which left behind multiple strata of sedimentary rock.[8]
In more recent times, massive ice sheets at least one kilometer thick ravaged the landscape of the state and sculpted its current terrain.[8] The Wisconsin glaciation left 12,000 years ago.[8] These glaciers covered all of Minnesota except the far southeast, an area characterized by steep hills and streams that cut into the bedrock. This area is known as the Driftless Zone for its absence of glacial drift.[11] Much of the remainder of the state outside of the northeast has 50 feet (15 m) or more of glacial till left behind as the last glaciers retreated. 13,000 years ago gigantic Lake Agassiz formed in the northwest; the lake's outflow, the glacial River Warren, carved the valley of the Minnesota River, and its bottom created the fertile lands of the Red River valley.[8] Minnesota is geologically quiet today; it experiences earthquakes infrequently, and most of them are minor.[12]
The state's high point is Eagle Mountain at 2,301 feet (701 m), which is only 13 miles (20.9 km) away from the low of 602 feet (183 m) at the shore of Lake Superior.[13][10] Notwithstanding dramatic local differences in elevation, much of the state is a gently rolling peneplain.[8]
Two continental divides meet in the northeastern part of Minnesota in rural Hibbing, forming a triple watershed. Precipitation can follow the Mississippi River south to the Gulf of Mexico, the St. Lawrence Seaway east to the Atlantic Ocean, or the Hudson Bay watershed to the Arctic Ocean.[14]
The state's nickname, The Land of 10,000 Lakes, is no exaggeration; there are 11,842 lakes over 10 acres (.04 km²) in size.[15] The Minnesota portion of Lake Superior is the largest at 962,700 acres (3,896 km²) and deepest (at 1,290 ft, 393 m) body of water in the state.[15] Minnesota has 6,564 natural rivers and streams that cumulatively flow for 69,000 miles (111,000 km).[15] The Mississippi River begins its journey from its headwaters at Lake Itasca and crosses the Iowa border 680 miles (1,094 km) downstream.[15] It is joined by the Minnesota River at Fort Snelling, by the St. Croix River near Hastings, by the Chippewa River at Wabasha, and by many smaller streams. The Red River, in the bed of glacial Lake Agassiz, drains the northwest part of the state northward toward Canada's Hudson Bay. Approximately 10.6 million acres (42,900 km²) of wetlands are contained within Minnesota's borders, the most of any state except Alaska.[16]
Flora and fauna

Three of North America's biomes converge in Minnesota: prairie grasslands in the southwestern and western parts of the state, the Big Woods deciduous forest of the southeast and east-central, and the northern boreal forest.[17] The northern coniferous forests are a vast wilderness of pine and spruce trees mixed with patchy stands of birch and poplar. Much of Minnesota's northern forest has been logged, leaving only a few patches of old growth forest today in areas such as in the Chippewa National Forest and the Superior National Forest where the Boundary Waters Canoe Area Wilderness has some 400,000 acres (1,600 km²) of unlogged land.[18] Although logging continues, regrowth keeps about one third of the state forested.[19]
While loss of habitat has affected native animals such as the pine marten, elk, and bison,[20] whitetail deer and bobcat thrive. The state has the nation's largest population of timber wolves outside Alaska,[21] and supports healthy populations of black bear and moose. Located on the Mississippi Flyway, Minnesota hosts migratory waterfowl such as geese and ducks, and game birds such as grouse, pheasants, and turkeys. It is home to birds of prey including the bald eagle, red-tailed hawk, and snowy owl. The lakes teem with the sport fish such as walleye, bass, muskellunge, and northern pike, and streams in the southeast are populated by brook, brown, and rainbow trout.
Climate

Minnesota endures temperature extremes characteristic of its continental climate; with cold winters and hot summers, the record high and low span 174 degrees Fahrenheit (96.6 °C).[22] Meteorological events include rain, snow, hail, blizzards, polar fronts, tornadoes, thunderstorms, and high-velocity straight-line winds. The growing season varies from 90 days per year in the Iron Range to 160 days in southeast Minnesota near the Mississippi River, and mean average temperatures range from 36 °F (2 °C) to 49 °F (9 °C).[23] Average summer dewpoints range from about 58 °F (14.4 °C) in the south to about 48 °F (8.9 °C) in the north.[23]
