126-619: The Mackinac Bridge Authority is an independent state agency of the U.S. state of Michigan that operates the Mackinac Bridge across the Straits of Mackinac . The Mackinac Bridge Authority has been directed by the state of Michigan to maintain the Mackinac Bridge as a self-supporting facility. The Mackinac Bridge is a toll bridge , with the tolls set at a level determined by the authority and its governing board. The Mackinac Bridge Authority

252-490: A 4.2-magnitude earthquake occurred on Saturday, May 2, 2015, shortly after noon, about five miles south of Galesburg, Michigan (9 miles southeast of Kalamazoo ) in central Michigan, about 140 miles west of Detroit, according to the Colorado-based U.S. Geological Survey 's National Earthquake Information Center . No major damage or injuries were reported, according to then-Governor Rick Snyder 's office. State government

378-529: A few hundred feet tall. It is divided by a low water divide running north and south. The larger portion of the state is on the west of this and gradually slopes toward Lake Michigan. The highest point in the Lower Peninsula is either Briar Hill at 1,705 feet (520 m), or one of several points nearby in the vicinity of Cadillac . The lowest point is the surface of Lake Erie at 571 feet (174 m). The geographic orientation of Michigan's peninsulas makes for

504-635: A landmark during the day to safely guide the passenger ships and freighters traveling the Great Lakes (see: lighthouses in the United States ). The state's rivers are generally small, short and shallow, and few are navigable. The principal ones include the Detroit River, St. Marys River, and St. Clair River which connect the Great Lakes; the Au Sable , Cheboygan , and Saginaw , which flow into Lake Huron;

630-532: A large mound of sand spanning the width of the river 55 feet below the surface, allowing fresh water and large cargo ships to pass over. Fresh river water flowing from the Mississippi into the Gulf of Mexico does not mix into the salt water immediately. The images from NASA 's MODIS show a large plume of fresh water, which appears as a dark ribbon against the lighter-blue surrounding waters. These images demonstrate that

756-703: A length of 3,710 miles (5,971 km), making it the fourth longest river in the world after the Nile , Amazon , and Yangtze . When measured by the largest stream source (by water volume), the Ohio River , by extension the Allegheny River , would be the source, and the Mississippi would begin in Pennsylvania . At its source at Lake Itasca , the Mississippi River is about 3 feet (0.91 m) deep. The average depth of

882-556: A long distance between the ends of the state. Ironwood , in the far western Upper Peninsula, lies 630 miles (1,010 kilometers) by highway from Lambertville in the Lower Peninsula's southeastern corner. The geographic isolation of the Upper Peninsula from Michigan's political and population centers makes the region culturally and economically distinct. Frequent attempts to establish the Upper Peninsula as its own state have failed to gain traction. A feature of Michigan that gives it

1008-478: A natural process known as avulsion or delta switching, the lower Mississippi River has shifted its final course to the mouth of the Gulf of Mexico every thousand years or so. This occurs because the deposits of silt and sediment begin to clog its channel, raising the river's level and causing it to eventually find a steeper, more direct route to the Gulf of Mexico. The abandoned distributaries diminish in volume and form what are known as bayous . This process has, over

1134-607: A nearly bloodless siege in 1812. A U.S. attempt to retake Detroit resulted in a severe American defeat in the River Raisin Massacre . This battle, still ranked as the bloodiest ever fought in the state, had the highest number of American casualties of any battle of the war. Michigan was recaptured by the Americans in 1813 after the Battle of Lake Erie . They used Michigan as a base to launch an invasion of Canada, which culminated in

1260-430: A permanent community there would strengthen French control over the upper Great Lakes and discourage British aspirations. The hundred soldiers and workers who accompanied Cadillac built a fort enclosing one arpent (about 0.85 acres (3,400 m ), the equivalent of just under 200 feet (61 m) per side) and named it Fort Pontchartrain . Cadillac's wife, Marie Thérèse Guyon, soon moved to Detroit, becoming one of

1386-577: A significant amount of population due to global competition and the dramatic unavailability of manufacturing jobs. Meanwhile, Michigan had increased use of technology, specifically when the IBM Personal Computer started selling in the state, in which became mostly used at work. Michigan became the leading auto-producing state in the U.S., with the industry primarily located throughout the Midwestern United States ; Ontario, Canada; and

1512-427: A warmer climate ( Köppen climate classification Dfa ) with hot summers and cold winters. The northern part of the Lower Peninsula and the entire Upper Peninsula has a more severe climate (Köppen Dfb ), with warm, but shorter summers and longer, cold to very cold winters. Some parts of the state average high temperatures below freezing from December through February, and into early March in the far northern parts. During

1638-809: Is 208,200 cu ft/s (5,900 m /s). Thus, by volume, the main branch of the Mississippi River system at Cairo can be considered to be the Ohio River (and the Allegheny River further upstream), rather than the Middle Mississippi. In addition to the Ohio River , the major tributaries of the Lower Mississippi River are the White River , flowing in at the White River National Wildlife Refuge in east-central Arkansas;

1764-558: Is a meandering river in a broad, flat area, only rarely flowing alongside a bluff (as at Vicksburg, Mississippi ). The Mississippi River is known as the Middle Mississippi from the Upper Mississippi River's confluence with the Missouri River at St. Louis, Missouri , for 190 miles (310 km) to its confluence with the Ohio River at Cairo, Illinois . The Middle Mississippi is relatively free-flowing. From St. Louis to

1890-622: Is bounded on the south by the states of Ohio and Indiana , sharing land and water boundaries with both. Michigan's western boundaries are almost entirely water boundaries, from south to north, with Illinois and Wisconsin in Lake Michigan; then a land boundary with Wisconsin and the Upper Peninsula, that is principally demarcated by the Menominee and Montreal Rivers ; then water boundaries again, in Lake Superior, with Wisconsin and Minnesota to

2016-494: Is called the Lower Mississippi River from its confluence with the Ohio River to its mouth at the Gulf of Mexico, a distance of about 1,000 miles (1,600 km). At the confluence of the Ohio and the Middle Mississippi, the long-term mean discharge of the Ohio at Cairo, Illinois is 281,500 cubic feet per second (7,970 cubic meters per second), while the long-term mean discharge of the Mississippi at Thebes, Illinois (just upriver from Cairo)

2142-868: Is controlled and managed as a series of pools created by 26 locks and dams. The Upper Mississippi River is joined by the Minnesota River at Fort Snelling in the Twin Cities ; the St. Croix River near Prescott, Wisconsin ; the Cannon River near Red Wing, Minnesota ; the Zumbro River at Wabasha, Minnesota ; the Black , La Crosse , and Root rivers in La Crosse, Wisconsin ; the Wisconsin River at Prairie du Chien, Wisconsin ;

2268-459: Is decentralized among three tiers—statewide, county and township . Counties are administrative divisions of the state, and townships are administrative divisions of a county. Both of them exercise state government authority, localized to meet the particular needs of their jurisdictions, as provided by state law. There are 83 counties in Michigan . Mississippi River The Mississippi River

2394-482: Is home to the country's three major automobile companies (whose headquarters are all in Metro Detroit). Once exploited for logging and mining, today the sparsely populated Upper Peninsula is important for tourism because of its abundance of natural resources. The Lower Peninsula is a center of manufacturing , forestry , agriculture , services , and high-tech industry. When the first European explorers arrived,

2520-509: Is largely a multi-thread stream with many bars and islands. From its confluence with the St. Croix River downstream to Dubuque, Iowa , the river is entrenched, with high bedrock bluffs lying on either side. The height of these bluffs decreases to the south of Dubuque, though they are still significant through Savanna, Illinois . This topography contrasts strongly with the Lower Mississippi, which

2646-519: Is rugged. The state's highest point, in the Huron Mountains northwest of Marquette, is Mount Arvon at 1,979 feet (603 m). The peninsula is as large as Connecticut, Delaware, Massachusetts, and Rhode Island combined but has fewer than 330,000 inhabitants. The people are sometimes called "Yoopers" (from "U.P.'ers"), and their speech (the " Yooper dialect ") has been heavily influenced by the numerous Scandinavian and Canadian immigrants who settled

2772-567: Is the primary river of the largest drainage basin in the United States . From its traditional source of Lake Itasca in northern Minnesota , it flows generally south for 2,340 miles (3,766 km) to the Mississippi River Delta in the Gulf of Mexico . With its many tributaries , the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between

2898-528: Is the only true waterfall on the entire Mississippi River. The water elevation continues to drop steeply as it passes through the gorge carved by the waterfall. After the completion of the St. Anthony Falls Lock and Dam in 1963, the river's head of navigation moved upstream, to the Coon Rapids Dam . However, the Locks were closed in 2015 to control the spread of invasive Asian carp , making Minneapolis once again

3024-459: Is the state's largest metropolitan area (roughly 50% of the population resides there) and the eleventh largest in the United States. The Grand Rapids metropolitan area in Western Michigan is the state's fastest-growing metro area, with more than 1.3 million residents as of 2006 . Michigan consists of two peninsulas separated by the Straits of Mackinac . The 45th parallel north runs through

3150-452: The 11th-largest by area, and the largest by area east of the Mississippi River . Its capital is Lansing , and its largest city is Detroit . Metro Detroit is among the nation's most populous and largest metropolitan economies. The name derives from a gallicized variant of the original Ojibwe word ᒥᓯᑲᒥ ( mishigami ), meaning "large water" or "large lake". Michigan consists of two peninsulas . The Lower Peninsula resembles

3276-604: The American Civil War , the Mississippi's capture by Union forces marked a turning point towards victory , due to the river's strategic importance to the Confederate war effort. Because of the substantial growth of cities and the larger ships and barges that replaced steamboats, the first decades of the 20th century saw the construction of massive engineering works such as levees , locks and dams , often built in combination. A major focus of this work has been to prevent

3402-547: The American Revolution . When Quebec split into Lower and Upper Canada in 1791, Michigan was part of Kent County , Upper Canada. It held its first democratic elections in August 1792 to send delegates to the new provincial parliament at Newark (now Niagara-on-the-Lake ). Under terms negotiated in the 1794 Jay Treaty , Britain withdrew from Detroit and Michilimackinac in 1796. It retained control of territory east and south of

3528-831: The Arkansas River , joining the Mississippi at Arkansas Post ; the Big Black River in Mississippi; and the Yazoo River , meeting the Mississippi at Vicksburg, Mississippi . Deliberate water diversion at the Old River Control Structure in Louisiana allows the Atchafalaya River in Louisiana to be a major distributary of the Mississippi River, with 30% of the combined flow of the Mississippi and Red Rivers flowing to

3654-631: The Battle of the Thames . But the more northern areas of Michigan were held by the British until the peace treaty restored the old boundaries. A number of forts, including Fort Wayne , were built by the United States in Michigan during the 19th century out of fears of renewed fighting with Britain. Michigan Territory governor and judges established the University of Michigan in 1817, as the Catholepistemiad, or

3780-536: The Guardian Building , each of which has been designated as a National Historic Landmark (NHL). In 1927 a school bombing took place in Clinton County . The Bath School disaster resulted in the deaths of 38 schoolchildren and constitutes the deadliest mass murder in a school in U.S. history. Michigan converted much of its manufacturing to satisfy defense needs during World War II ; it manufactured 10.9% of

3906-513: The Gulf of Mexico , part of the Atlantic Ocean. The total catchment of the Mississippi River covers nearly 40% of the landmass of the continental United States. The highest point within the watershed is also the highest point of the Rocky Mountains , Mount Elbert at 14,440 feet (4,400 m). In the United States, the Mississippi River drains the majority of the area between the crest of

4032-582: The Minnesota River , James River , and Milk River valleys. When the ice sheet completely retreated, many of these "temporary" rivers found paths to Hudson Bay or the Arctic Ocean, leaving the Mississippi Basin with many features "over-sized" for the existing rivers to have carved in the same time period. Ice sheets during the Illinoian Stage , about 300,000 to 132,000 years before present, blocked

4158-567: The Netherlands were especially numerous. Migration from Appalachia and of Black Southerners as part of the Great Migration increased in the 1930s, with many settling in Metro Detroit. Although Michigan has developed a diverse economy, in the early 20th century it became widely known as the center of the U.S. automotive industry , which developed as a major national economic force. It

4284-540: The North Country National Scenic Trail passes through Michigan. With 78 state parks , 19 state recreation areas, and six state forests , Michigan has the largest state park and state forest system of any state. Michigan has a continental climate with two distinct regions. The southern and central parts of the Lower Peninsula (south of Saginaw Bay and from the Grand Rapids area southward) have

4410-556: The Ohio and Missouri , formed pathways for the western expansion of the United States. The river also became the subject of American literature , particularly in the writings of Mark Twain . Formed from thick layers of the river's silt deposits, the Mississippi embayment is one of the most fertile regions of the United States; steamboats were widely used in the 19th and early 20th centuries to ship agricultural and industrial goods. During

4536-529: The Ontonagon , and Tahquamenon , which flow into Lake Superior; and the St. Joseph , Kalamazoo , Grand , Muskegon , Manistee , and Escanaba , which flow into Lake Michigan. The state has 11,037 inland lakes—totaling 1,305 square miles (3,380 km ) of inland water—in addition to 38,575 square miles (99,910 km ) of Great Lakes waters. No point in Michigan is more than six miles (9.7 km) from an inland lake or more than 85 miles (137 km) from one of

4662-1226: The Rock River at the Quad Cities ; the Iowa River near Wapello, Iowa ; the Skunk River south of Burlington, Iowa ; and the Des Moines River at Keokuk, Iowa . Other major tributaries of the Upper Mississippi include the Crow River in Minnesota, the Chippewa River in Wisconsin, the Maquoketa River and the Wapsipinicon River in Iowa, and the Illinois River in Illinois. The Upper Mississippi

4788-531: The Rocky and Appalachian mountains. The river either borders or passes through the states of Minnesota , Wisconsin , Iowa , Illinois , Missouri , Kentucky , Tennessee , Arkansas , Mississippi , and Louisiana . The main stem is entirely within the United States; the total drainage basin is 1,151,000 sq mi (2,980,000 km ), of which only about one percent is in Canada. The Mississippi ranks as

4914-403: The Rocky Mountains and the crest of the Appalachian Mountains , except for various regions drained to Hudson Bay by the Red River of the North ; to the Atlantic Ocean by the Great Lakes and the Saint Lawrence River ; and to the Gulf of Mexico by the Rio Grande , the Alabama and Tombigbee rivers, the Chattahoochee and Appalachicola rivers, and various smaller coastal waterways along

5040-425: The automotive industry . Ford's development of the moving assembly line in Highland Park marked a new era in transportation. Like the steamship and railroad, mass production of automobiles was a far-reaching development. More than the forms of public transportation, the affordable automobile transformed private life. Automobile production became the major industry of Detroit and Michigan, and permanently altered

5166-429: The headwaters region and serve multiple purposes, including power generation and recreation. The remaining 29 dams, beginning in downtown Minneapolis, all contain locks and were constructed to improve commercial navigation of the upper river. Taken as a whole, these 43 dams significantly shape the geography and influence the ecology of the upper river. Beginning just below Saint Paul, Minnesota , and continuing throughout

5292-422: The most recent Ice Age . The southernmost extent of this enormous glaciation extended well into the present-day United States and Mississippi basin. When the ice sheet began to recede, hundreds of feet of rich sediment were deposited, creating the flat and fertile landscape of the Mississippi Valley. During the melt, giant glacial rivers found drainage paths into the Mississippi watershed, creating such features as

5418-437: The 1830s, Michigan had 30,000 residents, more than enough to apply and qualify for statehood. On November 1, 1935, the U.S. Post Office issued a commemorative 3-cent stamp celebrating the 100th anniversary of Michigan statehood. Michigan's statehood, however, wasn't officially established until January 26, 1837, but since the campaign for statehood actually began in 1835, Michigan chose to hold its centennial celebration in 1935,

5544-430: The British forces, ending the French and Indian War (1754–1763), the North American front of the Seven Years' War in Europe. Under the 1763 Treaty of Paris , Michigan and the rest of New France east of the Mississippi River were ceded by defeated France to Great Britain. After the Quebec Act was passed in 1774, Michigan became part of the British Province of Quebec . By 1778, Detroit's population reached 2,144 and it

5670-418: The Detroit River, which are now included in Ontario, Canada. Questions remained over the boundary for many years, and the United States did not have uncontested control of the Upper Peninsula and Drummond Island until 1818 and 1847, respectively. During the War of 1812 , the United States forces at Fort Detroit surrendered Michigan Territory (effectively consisting of Detroit and the surrounding area) after

5796-402: The Earth's mantle (specifically, the Bermuda hotspot ) that was undergoing a period of intense activity. The upwelling of magma from the hotspot forced the further uplift to a height of perhaps 2–3 km of part of the Appalachian-Ouachita range, forming an arch that blocked southbound water flows. The uplifted land quickly eroded and, as North America moved away from the hot spot and as

5922-466: The French established a trading post and Fort St. Joseph along the St. Joseph River at the present-day city of Niles . In 1701, French explorer and army officer Antoine de la Mothe Cadillac founded Fort Pontchartrain du Détroit or "Fort Pontchartrain on-the-Strait" on the strait, known as the Detroit River , between lakes Saint Clair and Erie . Cadillac had convinced King Louis XIV's chief minister, Louis Phélypeaux, Comte de Pontchartrain , that

6048-400: The French rendering of the Anishinaabe ( Ojibwe or Algonquin ) name for the river, Misi-ziibi (Great River). In the 18th century, the river was set by the Treaty of Paris as, for the most part, the western border of the new United States. With the Louisiana Purchase and the country's westward expansion, it became a convenient boundary line between the western and eastern halves of

6174-559: The Great Lakes. The state is home to several areas maintained by the National Park Service including: Isle Royale National Park , in Lake Superior, about 30 miles (48 km) southeast of Thunder Bay, Ontario. Other national protected areas in the state include: Keweenaw National Historical Park , Pictured Rocks National Lakeshore , Sleeping Bear Dunes National Lakeshore , Huron National Forest , Manistee National Forest , Hiawatha National Forest , Ottawa National Forest and Father Marquette National Memorial . The largest section of

6300-588: The Gulf of Mexico by this route, rather than continuing down the Mississippi's current channel past Baton Rouge and New Orleans on a longer route to the Gulf. Although the Red River was once an additional tributary, its water now flows separately into the Gulf of Mexico through the Atchafalaya River. The Mississippi River has the world's fourth-largest drainage basin ("watershed" or "catchment"). The basin covers more than 1,245,000 square miles (3,220,000 km ), including all or parts of 32 U.S. states and two Canadian provinces. The drainage basin empties into

6426-409: The Gulf. The Mississippi River empties into the Gulf of Mexico about 100 miles (160 km) downstream from New Orleans. Measurements of the length of the Mississippi from Lake Itasca to the Gulf of Mexico vary somewhat, but the United States Geological Survey 's number is 2,340 miles (3,766 km). The retention time from Lake Itasca to the Gulf is typically about 90 days; while speed varies along

6552-404: The Illinoian Stage. Timeline of outflow course changes In March 1876, the Mississippi suddenly changed course near the settlement of Reverie, Tennessee , leaving a small part of Tipton County, Tennessee , attached to Arkansas and separated from the rest of Tennessee by the new river channel. Since this event was an avulsion , rather than the effect of incremental erosion and deposition,

6678-439: The Lower Peninsula, Michigan is drained by the Great Lakes- St. Lawrence watershed and is the only state with the majority of its land thus drained. No point in the state is more than six miles (9.7 km) from a natural water source or more than 85 miles (137 km) from a Great Lakes shoreline. The Great Lakes that border Michigan from east to west are Lake Erie , Lake Huron , Lake Michigan and Lake Superior . The state

William Gnodtke has been the chairman of the board since 2002, and the executive secretary is Kim Nowack since 2019. Michigan Michigan ( / ˈ m ɪ ʃ ɪ ɡ ən / MISH -ig-ən ) is a state in the Great Lakes region of the Upper Midwest region of the United States . It borders Wisconsin to

6930-408: The Midwestern and eastern U.S. These earthquakes created Reelfoot Lake in Tennessee from the altered landscape near the river. When measured from its traditional source at Lake Itasca , the Mississippi has a length of 2,340 miles (3,766 km). When measured from its longest stream source (most distant source from the sea), Brower's Spring in Montana , the source of the Missouri River , it has

7056-416: The Mississippi River between Saint Paul and Saint Louis is between 9 and 12 feet (2.7–3.7 m) deep, the deepest part being Lake Pepin , which averages 20–32 feet (6–10 m) deep and has a maximum depth of 60 feet (18 m). Between where the Missouri River joins the Mississippi at Saint Louis, Missouri, and Cairo, Illinois, the depth averages 30 feet (9 m). Below Cairo, where the Ohio River joins,

7182-411: The Mississippi River has experienced numerous large and small changes to its main course, as well as additions, deletions, and other changes among its numerous tributaries, and the lower Mississippi River has used different pathways as its main channel to the Gulf of Mexico across the delta region. As Pangaea began to break up about 95 million years ago, North America passed over a volcanic " hotspot " in

7308-415: The Mississippi River near New Madrid, Missouri , between Memphis and St. Louis, is related to an aulacogen (failed rift) that formed at the same time as the Gulf of Mexico. This area is still quite active seismically. Four great earthquakes in 1811 and 1812 , estimated at 8 on the Richter magnitude scale , had tremendous local effects in the then sparsely settled area, and were felt in many other places in

7434-404: The Mississippi near Rock Island, Illinois, diverting it to its present channel farther to the west, the current western border of Illinois. The Hennepin Canal roughly follows the ancient channel of the Mississippi downstream from Rock Island to Hennepin, Illinois . South of Hennepin, to Alton, Illinois , the current Illinois River follows the ancient channel used by the Mississippi River before

7560-529: The Missouri River; the Middle Mississippi, which is downriver from the Missouri to the Ohio River; and the Lower Mississippi , which flows from the Ohio to the Gulf of Mexico. The Upper Mississippi runs from its headwaters to its confluence with the Missouri River at St. Louis, Missouri. It is divided into two sections: The source of the Upper Mississippi branch is traditionally accepted as Lake Itasca , 1,475 feet (450 m) above sea level in Itasca State Park in Clearwater County, Minnesota . The name Itasca

7686-443: The Ohio River confluence, the Middle Mississippi falls 220 feet (67 m) over 180 miles (290 km) for an average rate of 1.2 feet per mile (23 cm/km). At its confluence with the Ohio River, the Middle Mississippi is 315 feet (96 m) above sea level. Apart from the Missouri and Meramec rivers of Missouri and the Kaskaskia River of Illinois, no major tributaries enter the Middle Mississippi River. The Mississippi River

Detroit is the centrally located metropolitan area of the Great Lakes megalopolis and the second-largest metropolitan area in the U.S. (after Chicago ) linking the Great Lakes system. The Metro Detroit area in Southeast Michigan

7938-639: The U.S.), an Anishinaabe tribe, were established in Michigan's Upper Peninsula and northern and central Michigan . Bands also inhabited Ontario and southern Manitoba , Canada; and northern Wisconsin , and northern and north-central Minnesota . The Ottawa Indians lived primarily south of the Straits of Mackinac in northern, western , and southern Michigan , but also in southern Ontario, northern Ohio, and eastern Wisconsin. The Potawatomi were in southern and western Michigan, in addition to northern and central Indiana, northern Illinois, southern Wisconsin, and southern Ontario. Other Algonquian tribes in Michigan, in

Detroit continued to expand through the 1950s, at one point doubling its population in a decade. After World War II, housing was developed in suburban areas outside city cores to meet demand for residences. The federal government subsidized the construction of interstate highways , which were intended to strengthen military access, but also allowed commuters and business traffic to travel

8190-400: The University of Michigania. The population grew slowly until the opening in 1825 of the Erie Canal through the Mohawk Valley in New York, connecting the Great Lakes to the Hudson River and New York City. The new route attracted a large influx of settlers to the Michigan territory. They worked as farmers, lumbermen, shipbuilders, and merchants and shipped out grain, lumber, and iron ore. By

8316-430: The Upper Mississippi River is the Upper St. Anthony Falls Lock and Dam in Minneapolis. Above the dam, the river's elevation is 799 feet (244 m). Below the dam, the river's elevation is 750 feet (230 m). This 49-foot (15 m) drop is the largest of all the Mississippi River locks and dams. The origin of the dramatic drop is a waterfall preserved adjacent to the lock under an apron of concrete. Saint Anthony Falls

8442-426: The Upper Mississippi is a simple steel culvert, through which the river (locally named "Nicolet Creek") flows north from Lake Nicolet under "Wilderness Road" to the West Arm of Lake Itasca, within Itasca State Park . The earliest bridge across the Mississippi River was built in 1855. It spanned the river in Minneapolis where the current Hennepin Avenue Bridge is located. No highway or railroad tunnels cross under

8568-463: The area during the lumbering and mining boom of the late 19th century. The Lower Peninsula is shaped like a mitten and many residents hold up a hand to depict where they are from. It is 277 miles (446 km) long from north to south and 195 miles (314 km) from east to west and occupies nearly two-thirds of the state's land area. The surface of the peninsula is generally level, broken by conical hills and glacial moraines usually not more than

8694-414: The area, settling largely along the waterways. After France's defeat in the French and Indian War in 1762, the region came under British rule. Britain ceded the territory to the newly independent United States after its defeat in the American Revolutionary War . The area was part of the larger Northwest Territory until 1800, when western Michigan became part of the Indiana Territory . Michigan Territory

8820-555: The areas drained by them. Denser salt water from the Gulf of Mexico forms a salt wedge along the river bottom near the mouth of the river, while fresh water flows near the surface. In drought years, with less fresh water to push it out, salt water can travel many miles upstream—64 miles (103 km) in 2022—contaminating drinking water supplies and requiring the use of desalination . The United States Army Corps of Engineers constructed "saltwater sills" or "underwater levees" to contain this in 1988, 1999, 2012, and 2022. This consists of

On August 12, 2005, Jeff asserted engineering inspections and insurance would be handled by MDOT instead of the MBA based on a 40-year-old Attorney General's opinion; Jeff would not release the opinion. In September 2005, Governor Jennifer Granholm was in talks between MDOT and the MBA to develop an agreement between

9198-464: The authority was originally scheduled for dissolution in 1986 after the last of the bonds were to be paid in full. Over the course of 2004 and 2005, the Michigan Department of Transportation (MDOT) Director Gloria Jeff made moves to challenge the independence of the authority against previous practices claiming that the authority is not an independent agency. In 2004, Jeff moved $ 25 million from

9324-472: The coast is much indented. Keweenaw Bay, Whitefish Bay , and the Big and Little Bays De Noc are the principal indentations on the Upper Peninsula. The Grand and Little Traverse , Thunder , and Saginaw bays indent the Lower Peninsula. Michigan has the second longest shoreline of any state—3,288 miles (5,292 km), including 1,056 miles (1,699 km) of island shoreline. The state has numerous large islands ,

9450-552: The coldest recorded temperature is −51 °F (−46 °C) at Vanderbilt on February 9, 1934. The state averages 30 days of thunderstorm activity per year. These can be severe, especially in the southern part of the state. The state averages 17 tornadoes per year, which are more common in the state's extreme southern section. Portions of the southern border have been almost as vulnerable historically as states further west and in Tornado Alley . For this reason, many communities in

9576-582: The country. This is reflected in the Gateway Arch in St. Louis, which was designed to symbolize the opening of the West, and the focus on the " Trans-Mississippi " region in the Trans-Mississippi Exposition . Regional landmarks are often classified in relation to the river, such as "the highest peak east of the Mississippi " or "the oldest city west of the Mississippi". The FCC also uses it as

9702-427: The course of the river, this gives an overall average of around 26 mi (42 km) per day, or 1 mi (1.6 km) per hour. The stream gradient of the entire river is 0.01%, a drop of 450 m over 3,766 km. The Mississippi River discharges at an annual average rate of between 200 and 700 thousand cubic feet per second (6,000 and 20,000 m /s). The Mississippi is the fourteenth largest river in

9828-403: The delta of the Chippewa River of Wisconsin as it enters the Upper Mississippi, is more than 2 miles (3.2 km) wide. By the time the Upper Mississippi reaches Saint Paul , Minnesota, below Lock and Dam No. 1, it has dropped more than half its original elevation and is 687 feet (209 m) above sea level. From St. Paul to St. Louis, Missouri, the river elevation falls much more slowly and

9954-586: The depth averages 50–100 feet (15–30 m) deep. The deepest part of the river is in New Orleans, where it reaches 200 feet (61 m) deep. The Mississippi River runs through or along 10 states, from Minnesota to Louisiana , and is used to define portions of these states' borders, with Wisconsin , Illinois , Kentucky , Tennessee , and Mississippi along the east side of the river, and Iowa , Missouri , and Arkansas along its west side. Substantial parts of both Minnesota and Louisiana are on either side of

10080-651: The distinct shape of a mitten is the Thumb , which projects into Lake Huron, forming Saginaw Bay . Other notable peninsulas of Michigan include the Keweenaw Peninsula , which projects northeasterly into Lake Superior from the Upper Peninsula and largely comprising Michigan's Copper Country region, and the Leelanau Peninsula , projecting from the Lower Peninsula into Lake Michigan, forming Michigan's "little finger". Numerous lakes and marshes mark both peninsulas, and

10206-464: The dividing line for broadcast call-signs , which begin with W to the east and K to the west, overlapping in media markets along the river. Due to its size and importance, it has been nicknamed The Mighty Mississippi River or simply The Mighty Mississippi . The Mississippi River can be divided into three sections: the Upper Mississippi , the river from its headwaters to the confluence with

10332-679: The entire Lower Peninsula. The Upper Peninsula exhibits Lower Silurian sandstones, limestones, copper and iron bearing rocks, corresponding to the Huronian system of Canada . The central portion of the Lower Peninsula contains coal measures and rocks of the Pennsylvanian period. Devonian and sub-Carboniferous deposits are scattered over the entire state. Michigan rarely experiences earthquakes , and those that it does experience are generally smaller ones that do not cause significant damage. A 4.6-magnitude earthquake struck in August 1947. More recently,

10458-488: The first European women to settle in what was considered the wilderness of Michigan. The town quickly became a major fur-trading and shipping post. The Église de Saint-Anne (Catholic Church of Saint Anne) was founded the same year. While the original building does not survive, the congregation remains active. Cadillac later departed to serve as the French governor of Louisiana from 1710 to 1716. French attempts to consolidate

10584-529: The five Great Lakes and Lake St. Clair . It also has 64,980 inland lakes and ponds . Michigan has the second-most water area of any state, behind only Alaska. The area was first occupied by a succession of Native American tribes over thousands of years. In the 17th century, French explorers claimed it as part of the New France colony, when it was largely inhabited by Indigenous peoples. French and Canadian traders and settlers, Métis , and others migrated to

10710-550: The fur trade led to the Fox Wars , in which the Meskwaki (Fox) and their allies fought the French and their Native allies. At the same time, the French strengthened Fort Michilimackinac at the Straits of Mackinac to better control their lucrative fur-trading empire. By the mid-18th century, the French also occupied forts at present-day Niles and Sault Ste. Marie, though most of the rest of

10836-496: The hotspot's activity declined, the crust beneath the embayment region cooled, contracted and subsided to a depth of 2.6 km, and around 80 million years ago the Reelfoot Rift formed a trough that was flooded by the Gulf of Mexico . As sea levels dropped, the Mississippi and other rivers extended their courses into the embayment , which gradually became filled with sediment with the Mississippi River at its center. Through

10962-402: The last two decades, this number was only 160 million short tons (145 million metric tons) per year. The reduction in sediment transported down the Mississippi River is the result of engineering modification of the Mississippi, Missouri, and Ohio rivers and their tributaries by dams, meander cutoffs , river-training structures, and bank revetments and soil erosion control programs in

11088-677: The late 19th to early 20th century, working in lumbering areas in counties on the Lake Huron side of the Lower Peninsula, such as the Saginaw Valley, Alpena, and Cheboygan counties, as well as throughout the Upper Peninsula, with large concentrations in Escanaba and the Keweenaw Peninsula . The first statewide meeting of the Republican Party took place on July 6, 1854, in Jackson, Michigan , where

11214-546: The lower 10 miles (16 km) of the Kaskaskia River, forming a new Mississippi channel and cutting off the town from the rest of the state. Later flooding destroyed most of the remaining town, including the original State House. Today, the remaining 2,300 acres (930 ha) island and community of 14 residents is known as an enclave of Illinois and is accessible only from the Missouri side. The New Madrid Seismic Zone , along

11340-415: The lower Mississippi from shifting into the channel of the Atchafalaya River and bypassing New Orleans . Since the 20th century, the Mississippi River has also experienced major pollution and environmental problems — most notably elevated nutrient and chemical levels from agricultural runoff, the primary contributor to the Gulf of Mexico dead zone . The word Mississippi itself comes from Misi zipi ,

11466-646: The most populous tribes were the Algonquian peoples , which include the Anishinaabe groups of Ojibwe , Odaawaa/Odawa (Ottawa) , and the Boodewaadamii/Bodéwadmi (Potawatomi) . The three nations coexisted peacefully as part of a loose confederation called the Council of Three Fires . The Ojibwe, whose numbers are estimated to have been at least 35,000, were the largest. The Ojibwe Indians (also known as Chippewa in

11592-456: The nation. Many private colleges were founded as well, and the smaller cities established high schools late in the century. Michigan's economy underwent a transformation at the turn of the 20th century. Many individuals, including Ransom E. Olds , John and Horace Dodge , Henry Leland , David Dunbar Buick , Henry Joy , Charles King , and Henry Ford , provided the concentration of engineering know-how and technological enthusiasm to develop

11718-440: The native way of life as first explorers, then settlers, ventured into the basin in increasing numbers. The river served sometimes as a barrier, forming borders for New Spain , New France , and the early United States, and throughout as a vital transportation artery and communications link. In the 19th century, during the height of the ideology of manifest destiny , the Mississippi and several tributaries, most notably its largest,

11844-449: The new river channel, contiguous with the adjacent state. Also, due to a meander in the river, a small part of western Kentucky is contiguous with Tennessee but isolated from the rest of its state. Many of the communities along the Mississippi River are listed below; most have either historic significance or cultural lore connecting them to the river. They are sequenced from the source of the river to its end. The road crossing highest on

11970-603: The party adopted its platform. The state was predominantly Republican until the 1930s, reflecting the political continuity of migrants from across the Northern Tier of New England and New York. Michigan made a significant contribution to the Union in the American Civil War and sent more than forty regiments of volunteers to the federal armies. Michigan modernized and expanded its system of education in this period. The Michigan State Normal School, now Eastern Michigan University ,

12096-598: The past 5,000 years, caused the coastline of south Louisiana to advance toward the Gulf from 15 to 50 miles (24 to 80 km). The currently active delta lobe is called the Birdfoot Delta, after its shape, or the Balize Delta , after La Balize, Louisiana , the first French settlement at the mouth of the Mississippi. The current form of the Mississippi River basin was largely shaped by the Laurentide Ice Sheet of

12222-489: The plume did not mix with the surrounding sea water immediately. Instead, it stayed intact as it flowed through the Gulf of Mexico, into the Straits of Florida , and entered the Gulf Stream . The Mississippi River water rounded the tip of Florida and traveled up the southeast coast to the latitude of Georgia before finally mixing in so thoroughly with the ocean that it could no longer be detected by MODIS. Over geologic time,

12348-441: The population boom. By the 1930s, so many immigrants had arrived that more than 30 languages were spoken in the public schools, and ethnic communities celebrated in annual heritage festivals. Over the years immigrants and migrants contributed greatly to Detroit's diverse urban culture, including popular music trends. The influential Motown Sound of the 1960s was led by a variety of individual singers and groups. Grand Rapids ,

12474-539: The principal ones being the North Manitou and South Manitou , Beaver , and Fox groups in Lake Michigan; Isle Royale and Grande Isle in Lake Superior; Marquette, Bois Blanc , and Mackinac islands in Lake Huron; and Neebish , Sugar , and Drummond islands in St. Mary's River . Michigan has about 150 lighthouses , the most of any U.S. state. The first lighthouses in Michigan were built between 1818 and 1822. They were built to project light at night and to serve as

12600-571: The region more easily. Since 1960, modern advances in the auto industry have led to increased automation, high-tech industry, and increased suburban growth. Longstanding tensions in Detroit culminated in the Twelfth Street riot in July 1967. During the late 1970s and the early 1980s, increasing fuel costs and other factors made significantly more global competition and recession among families. Michigan lost

12726-510: The region remained unsettled by Europeans. France offered free land to attract families to Detroit, which grew to 800 people in 1765. It was the largest city between Montreal and New Orleans. French settlers also established small farms south of the Detroit River opposite the fort, near a Jesuit mission and Huron village. From 1660 until the end of French rule, Michigan was part of the Royal Province of New France . In 1760, Montreal fell to

12852-479: The river, although the Mississippi defines part of the boundary of each of these states. In all of these cases, the middle of the riverbed at the time the borders were established was used as the line to define the borders between adjacent states. In various areas, the river has since shifted, but the state borders have not changed, still following the former bed of the Mississippi River as of their establishment, leaving several small isolated areas of one state across

12978-528: The second-largest city in Michigan also became an important center of manufacturing. Since 1838, the city has been noted for its furniture industry. In the 21st century, it is home to five of the world's leading office furniture companies. Grand Rapids is home to a number of major companies including Steelcase , Amway , and Meijer . Grand Rapids is also an important center for GE Aviation Systems . Michigan held its first United States presidential primary election in 1910. With its rapid growth in industry, it

13104-435: The shape of a mitten , and comprises a majority of the state's land area. The Upper Peninsula (often called "the U.P.") is separated from the Lower Peninsula by the Straits of Mackinac , a five-mile (8 km) channel that joins Lake Huron to Lake Michigan. The Mackinac Bridge connects the peninsulas. Michigan has the longest freshwater coastline of any political subdivision in the United States, being bordered by four of

13230-400: The site of the head of navigation of the river. The Upper Mississippi has a number of natural and artificial lakes, with its widest point being Lake Winnibigoshish , near Grand Rapids, Minnesota , over 11 miles (18 km) across. Lake Onalaska , created by Lock and Dam No. 7 , near La Crosse, Wisconsin , is more than 4 miles (6.4 km) wide. Lake Pepin , a natural lake formed behind

13356-418: The socioeconomic life of the United States and much of the world. With the growth, the auto industry created jobs in Detroit that attracted immigrants from Europe and migrants from across the United States, including both blacks and whites from the rural South . By 1920, Detroit was the fourth-largest city in the U.S.. Residential housing was in short supply, and it took years for the market to catch up with

13482-857: The south and east, were the Mascouten , the Menominee , the Miami , the Sac (or Sauk), and the Meskwaki (Fox) . The Wyandot were an Iroquoian-speaking people in this area; they were historically known as the Huron by the French, and were the historical adversaries of the Iroquois Confederation . French voyageurs and coureurs des bois explored and settled in Michigan in the 17th century. The first Europeans to reach what became Michigan were those of Étienne Brûlé 's expedition in 1622. The first permanent European settlement

13608-566: The southwest in the Upper Peninsula , and Indiana and Ohio to the south in the Lower Peninsula ; it is also connected by Lakes Superior , Michigan , Huron , and Erie to Minnesota and Illinois , and the Canadian province of Ontario . With a population of nearly 10.12 million and an area of 96,716 sq mi (250,490 km ), Michigan is the 10th-largest state by population,

13734-524: The state line still follows the old channel. The town of Kaskaskia, Illinois once stood on a peninsula at the confluence of the Mississippi and Kaskaskia (Okaw) Rivers . Founded as a French colonial community, it later became the capital of the Illinois Territory and was the first state capital of Illinois until 1819. Beginning in 1844, successive flooding caused the Mississippi River to slowly encroach east. A major flood in 1881 caused it to overtake

13860-518: The state, marked by highway signs and the Polar-Equator Trail— along a line including Mission Point Light near Traverse City , the towns of Gaylord and Alpena in the Lower Peninsula and Menominee in the Upper Peninsula. With the exception of two tiny areas drained by the Mississippi River by way of the Wisconsin River in the Upper Peninsula and by way of the Kankakee - Illinois River in

13986-549: The two agencies to solve the recent issues brought to the fore as the MDOT Director attempt to cut cost, due to statewide budget pressures, at the authority by reducing the board's power. The talks ended with an agreement for the bridge authority to resume operations as it has in the past with MDOT implementing its decisions and the MDOT Chief Deputy Director Kirk Steudle assigned the director's position on

14112-567: The upper and lower river, the Mississippi is further controlled by thousands of wing dikes that moderate the river's flow in order to maintain an open navigation channel and prevent the river from eroding its banks. The head of navigation on the Mississippi is the St. Anthony Falls Lock. Before the Coon Rapids Dam in Coon Rapids, Minnesota , was built in 1913, steamboats could occasionally go upstream as far as Saint Cloud, Minnesota , depending on river conditions. The uppermost lock and dam on

14238-583: The very southern portions of the state have tornado sirens to warn residents of approaching tornadoes. Farther north, in Central Michigan, Northern Michigan, and the Upper Peninsula, tornadoes are rare. The geological formation of the state is greatly varied, with the Michigan Basin being the most major formation. Primary boulders are found over the entire surface of the Upper Peninsula (being principally of primitive origin), while Secondary deposits cover

14364-507: The west, capped around by the Canadian province of Ontario to the north and east. The heavily forested Upper Peninsula is relatively mountainous in the west. The Porcupine Mountains , which are part of one of the oldest mountain chains in the world, rise to an altitude of almost 2,000 feet (610 m) above sea level and form the watershed between the streams flowing into Lake Superior and Lake Michigan. The surface on either side of this range

14490-493: The western part of the Upper Peninsula as a concession and formally entered the Union as a free state on January 26, 1837. The Upper Peninsula proved to be a rich source of lumber, iron, and copper. Michigan led the nation in lumber production from the 1850s to the 1880s. Railroads became a major engine of growth from the 1850s onward, with Detroit the chief hub . A second wave of French-Canadian immigrants settled in Michigan during

14616-432: The winter through the middle of February, the state is frequently subjected to heavy lake-effect snow . The state averages from 30 to 40 inches (76 to 102 cm) of precipitation annually; however, some areas in the northern lower peninsula and the upper peninsula average almost 160 inches (4,100 mm) of snowfall per year. Michigan's highest recorded temperature is 112 °F (44 °C) at Mio on July 13, 1936, and

14742-473: The world by volume. On average, the Mississippi has 8% the flow of the Amazon River , which moves nearly 7 million cubic feet per second (200,000 m /s) during wet seasons. Before 1900, the Mississippi River transported an estimated 440 million short tons (400 million metric tons) of sediment per year from the interior of the United States to coastal Louisiana and the Gulf of Mexico. During

14868-513: The world's tenth-largest river by discharge flow, and the largest in North America. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Many were hunter-gatherers , but some, such as the Mound Builders , formed prolific agricultural and urban civilizations, and some practiced aquaculture . The arrival of Europeans in the 16th century changed

14994-456: The year the stamp was first issued. A constitutional convention of assent was held to lead the territory to statehood. In October 1835 the people approved the constitution of 1835, thereby forming a state government. Congressional recognition was delayed pending resolution of a boundary dispute with Ohio known as the Toledo War . Congress awarded the "Toledo Strip" to Ohio. Michigan received

15120-533: Was an important center of industry-wide union organizing, such as the rise of the United Auto Workers . In 1920 WWJ (AM) in Detroit became the first radio station in the United States to regularly broadcast commercial programs. Throughout that decade, some of the country's largest and most ornate skyscrapers were built in the city. Particularly noteworthy are the Fisher Building , Cadillac Place , and

15246-496: Was chosen to designate the "true head" of the Mississippi River as a combination of the last four letters of the Latin word for truth ( ver itas ) and the first two letters of the Latin word for head ( ca put ). However, the lake is in turn fed by a number of smaller streams. From its origin at Lake Itasca to St. Louis, Missouri , the waterway's flow is moderated by 43 dams. Fourteen of these dams are located above Minneapolis in

15372-436: Was created in 1950 to study the feasibility of constructing a suspension bridge to connect Michigan's Lower Peninsula with its Upper Peninsula The MBA was empowered by legislation in 1952 "to issue revenue bonds 'for the purpose of paying for the cost of a bridge ' ". The authority managed the bridge's construction from 1954 until 1957, and has overseen the operation of the bridge since its opening on November 1, 1957, although

15498-463: Was formed in 1805, but some of the northern border with Canada was not agreed upon until after the War of 1812 . Michigan was admitted into the Union in 1837 as the 26th state, a free one . It soon became an important center of industry and trade in the Great Lakes region, attracting immigrants in the late 19th and early 20th centuries from many European countries . Immigrants from Finland , Macedonia , and

15624-438: Was founded in 1668 on the site where Père Jacques Marquette established Sault Ste. Marie, Michigan , as a base for Catholic missions. Missionaries in 1671–75 founded outlying stations at Saint Ignace and Marquette . Jesuit missionaries were well received by the area's Indian populations, with few difficulties or hostilities. In 1679, Robert Cavelier, Sieur de la Salle built Fort Miami at present-day St. Joseph . In 1691,

15750-559: Was founded in 1849, for the training of teachers. It was the fourth oldest normal school in the United States and the first U.S. normal school outside New England . In 1899, the Michigan State Normal School became the first normal school in the nation to offer a four-year curriculum. Michigan Agricultural College (1855), now Michigan State University in East Lansing , was founded as the first agricultural college in

15876-565: Was the third-largest city in Quebec province. During the American Revolutionary War , Detroit was an important British supply center. Most of the inhabitants were French-Canadians or American Indians, many of whom had been allied with the French because of long trading ties. Because of imprecise cartography and unclear language defining the boundaries in the 1783 Treaty of Paris , the British retained control of Detroit and Michigan after
