The Missouri River is the longest river in North America. Rising in the Rocky Mountains of western Montana, the Missouri flows east and south for 2,341 miles before entering the Mississippi River north of St. Louis, Missouri; the river takes drainage from a sparsely populated, semi-arid watershed of more than half a million square miles, which includes parts of ten U. S. states and two Canadian provinces. When combined with the lower Mississippi River, it forms the world's fourth longest river system. For over 12,000 years, people have depended on the Missouri River and its tributaries as a source of sustenance and transportation. More than ten major groups of Native Americans populated the watershed, most leading a nomadic lifestyle and dependent on enormous bison herds that roamed through the Great Plains; the first Europeans encountered the river in the late seventeenth century, the region passed through Spanish and French hands before becoming part of the United States through the Louisiana Purchase.
The Missouri River was one of the main routes for the westward expansion of the United States during the 19th century. The growth of the fur trade in the early 19th century laid much of the groundwork as trappers explored the region and blazed trails. Pioneers headed west en masse beginning in the 1830s, first by covered wagon by the growing numbers of steamboats that entered service on the river. Settlers took over former Native American lands in the watershed, leading to some of the most longstanding and violent wars against indigenous peoples in American history. During the 20th century, the Missouri River basin was extensively developed for irrigation, flood control and the generation of hydroelectric power. Fifteen dams impound the main stem of the river, with hundreds more on tributaries. Meanders have been cut and the river channelized to improve navigation, reducing its length by 200 miles from pre-development times. Although the lower Missouri valley is now a populous and productive agricultural and industrial region, heavy development has taken its toll on wildlife and fish populations as well as water quality.
From the Rocky Mountains of Montana and Wyoming, three streams rise to form the headwaters of the Missouri River: the longest begins near Brower's Spring, 9,100 feet above sea level on the southeastern slopes of Mount Jefferson in the Centennial Mountains. From there it flows west north, it passes through Canyon Ferry Lake, a reservoir west of the Big Belt Mountains. Issuing from the mountains near Cascade, the river flows northeast to the city of Great Falls, where it drops over the Great Falls of the Missouri, a series of five substantial waterfalls, it winds east through a scenic region of canyons and badlands known as the Missouri Breaks, receiving the Marias River from the west widening into the Fort Peck Lake reservoir a few miles above the confluence with the Musselshell River. Farther on, the river passes through the Fort Peck Dam, downstream, the Milk River joins from the north. Flowing eastward through the plains of eastern Montana, the Missouri receives the Poplar River from the north before crossing into North Dakota where the Yellowstone River, its greatest tributary by volume, joins from the southwest.
At the confluence, the Yellowstone is the larger river. The Missouri meanders east past Williston and into Lake Sakakawea, the reservoir formed by Garrison Dam. Below the dam the Missouri receives the Knife River from the west and flows south to Bismarck, the capital of North Dakota, where the Heart River joins from the west, it slows into the Lake Oahe reservoir just before the Cannonball River confluence. While it continues south reaching Oahe Dam in South Dakota, the Grand and Cheyenne Rivers all join the Missouri from the west; the Missouri makes a bend to the southeast as it winds through the Great Plains, receiving the Niobrara River and many smaller tributaries from the southwest. It proceeds to form the boundary of South Dakota and Nebraska after being joined by the James River from the north, forms the Iowa–Nebraska boundary. At Sioux City the Big Sioux River comes in from the north; the Missouri flows south to the city of Omaha where it receives its longest tributary, the Platte River, from the west.
Downstream, it begins to define the Nebraska–Missouri border flows between Missouri and Kansas. The Missouri swings east at Kansas City, where the Kansas River enters from the west, so on into north-central Missouri. To the east of Kansas City, the Missouri receives, on the left side, the Grand River, it passes south of Columbia and receives the Osage and Gasconade Rivers from the south downstream of Jefferson City. The river rounds the northern side of St. Louis to join the Mississippi River on the border between Missouri and Illinois. With a drainage basin spanning 529,350 square miles, the Missouri River's catchment encompasses nearly one-sixth of the area of the United States or just over five percent of the continent of North America. Comparable to the size of the Canadian province of Quebec, the watershed encompasses most of the central Great Plains, stretching from the Rocky Mountains in the
The Ohio River is a 981-mile long river in the midwestern United States that flows southwesterly from western Pennsylvania south of Lake Erie to its mouth on the Mississippi River at the southern tip of Illinois. It is the second largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River that divides the eastern from western United States; the river flows through or along the border of six states, its drainage basin includes parts of 15 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern U. S, it is the source of drinking water for three million people. The lower Ohio River just below Louisville is obstructed by rapids known as the Falls of the Ohio where the water level falls 26ft. in 2 miles and is impassible for navigation. The McAlpine Locks and Dam, a shipping canal bypassing the rapids, now allows commercial navigation from the Forks of the Ohio at Pittsburgh to the Port of New Orleans at the mouth of the Mississippi on the Gulf of Mexico.
The name "Ohio" comes from the Ohi: yo', lit. "Good River". Discovery of the Ohio River may be attributed to English explorers from Virginia in the latter half of the 17th century. In his Notes on the State of Virginia published in 1781–82, Thomas Jefferson stated: "The Ohio is the most beautiful river on earth, its current gentle, waters clear, bosom smooth and unbroken by rocks and rapids, a single instance only excepted." In the late 18th century, the river was the southern boundary of the Northwest Territory. It became a primary transportation route for pioneers during the westward expansion of the early U. S; the river is sometimes considered as the western extension of the Mason–Dixon Line that divided Pennsylvania from Maryland, thus part of the border between free and slave territory, between the Northern and Southern United States or Upper South. Where the river was narrow, it was the way to freedom for thousands of slaves escaping to the North, many helped by free blacks and whites of the Underground Railroad resistance movement.
The Ohio River is a climatic transition area, as its water runs along the periphery of the humid subtropical and humid continental climate areas. It is inhabited by flora of both climates. In winter, it freezes over at Pittsburgh but farther south toward Cincinnati and Louisville. At Paducah, Kentucky, in the south, near the Ohio's confluence with the Mississippi, it is ice-free year-round; the name "Ohio" comes from the Seneca language, Ohi:yo', a proper name derived from ohiːyoːh, therefore translating to "Good River". "Great river" and "large creek" have been given as translations. Native Americans, including the Lenni Lenape and Iroquois, considered the Ohio and Allegheny rivers as the same, as is suggested by a New York State road sign on Interstate 86 that refers to the Allegheny River as Ohi:yo'. An earlier Miami-Illinois language name was applied to the Ohio River, Mosopeleacipi. Shortened in the Shawnee language to pelewa thiipi, spelewathiipi or peleewa thiipiiki, the name evolved through variant forms such as "Polesipi", "Peleson", "Pele Sipi" and "Pere Sipi", stabilized to the variant spellings "Pelisipi", "Pelisippi" and "Pellissippi".
Applied just to the Ohio River, the "Pelisipi" name was variously applied back and forth between the Ohio River and the Clinch River in Virginia and Tennessee. In his original draft of the Land Ordinance of 1784, Thomas Jefferson proposed a new state called "Pelisipia", to the south of the Ohio River, which would have included parts of present-day Eastern Kentucky and West Virginia; the river had great significance in the history of the Native Americans, as numerous civilizations formed along its valley. For thousands of years, Native Americans used the river as a major trading route, its waters connected communities. In the five centuries before European conquest, the Mississippian culture built numerous regional chiefdoms and major earthwork mounds in the Ohio Valley, such as Angel Mounds near Evansville, Indiana, as well as in the Mississippi Valley and the Southeast; the Osage, Omaha and Kaw lived in the Ohio Valley, but under pressure from the Iroquois to the northeast, migrated west of the Mississippi River in the 17th century to territory now defined as Missouri and Oklahoma.
The discovery and traversal of the Ohio River by Europeans admits of several possibilities, all in the latter half of the 17th century. Virginian Englishman Abraham Wood's trans-Appalachian expeditions between 1654 and 1664; the first person to traverse the length of the river, from the headwaters of the Allegheny to its mouth on the Mississippi, was a Dutch trader from New York, Arnout Viele, in 1692. In 1749, Great Britain established the Ohio Company to trade in the area. Exploration of the territory and trade with the Indians in the region near the Forks brought British colonials from both Pennsylvania and Virginia across the mountains, both colonies claimed the territory; the movement across the Allegheny Mountains of British settlers and the claims of the area near modern day Pittsburgh led to conflict with the French, who had forts in the Ohio River Valley. This conflict was called the Indian War. In 17
Virginia the Commonwealth of Virginia, is a state in the Southeastern and Mid-Atlantic regions of the United States located between the Atlantic Coast and the Appalachian Mountains. Virginia is nicknamed the "Old Dominion" due to its status as the first English colonial possession established in mainland North America and "Mother of Presidents" because eight U. S. presidents were born there, more than any other state. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna; the capital of the Commonwealth is Richmond. The Commonwealth's estimated population as of 2018 is over 8.5 million. The area's history begins with several indigenous groups, including the Powhatan. In 1607 the London Company established the Colony of Virginia as the first permanent New World English colony. Slave labor and the land acquired from displaced Native American tribes each played a significant role in the colony's early politics and plantation economy.
Virginia was one of the 13 Colonies in the American Revolution. In the American Civil War, Virginia's Secession Convention resolved to join the Confederacy, Virginia's First Wheeling Convention resolved to remain in the Union. Although the Commonwealth was under one-party rule for nearly a century following Reconstruction, both major national parties are competitive in modern Virginia; the Virginia General Assembly is the oldest continuous law-making body in the New World. The state government was ranked most effective by the Pew Center on the States in both 2005 and 2008, it is unique in how it treats cities and counties manages local roads, prohibits its governors from serving consecutive terms. Virginia's economy has many sectors: agriculture in the Shenandoah Valley. S. Department of Defense and Central Intelligence Agency. Virginia has a total area of 42,774.2 square miles, including 3,180.13 square miles of water, making it the 35th-largest state by area. Virginia is bordered by Maryland and Washington, D.
C. to the north and east. Virginia's boundary with Maryland and Washington, D. C. extends to the low-water mark of the south shore of the Potomac River. The southern border is defined as the 36° 30′ parallel north, though surveyor error led to deviations of as much as three arcminutes; the border with Tennessee was not settled until 1893, when their dispute was brought to the U. S. Supreme Court; the Chesapeake Bay separates the contiguous portion of the Commonwealth from the two-county peninsula of Virginia's Eastern Shore. The bay was formed from the drowned river valleys of the James River. Many of Virginia's rivers flow into the Chesapeake Bay, including the Potomac, Rappahannock and James, which create three peninsulas in the bay; the Tidewater is a coastal plain between the fall line. It includes major estuaries of Chesapeake Bay; the Piedmont is a series of sedimentary and igneous rock-based foothills east of the mountains which were formed in the Mesozoic era. The region, known for its heavy clay soil, includes the Southwest Mountains around Charlottesville.
The Blue Ridge Mountains are a physiographic province of the Appalachian Mountains with the highest points in the state, the tallest being Mount Rogers at 5,729 feet. The Ridge and Valley region includes the Great Appalachian Valley; the region includes Massanutten Mountain. The Cumberland Plateau and the Cumberland Mountains are in the southwest corner of Virginia, south of the Allegheny Plateau. In this region, rivers flow northwest, into the Ohio River basin; the Virginia Seismic Zone has not had a history of regular earthquake activity. Earthquakes are above 4.5 in magnitude, because Virginia is located away from the edges of the North American Plate. The largest earthquake, at an estimated 5.9 magnitude, was in 1897 near Blacksburg. A 5.8 magnitude earthquake struck central Virginia on August 2011, near Mineral. The earthquake was felt as far away as Toronto and Florida. 35 million years ago, a bolide impacted. The resulting Chesapeake Bay impact crater may explain what earthquakes and subsidence the region does experience.
Coal mining takes place in the three mountainous regions at 45 distinct coal beds near Mesozoic basins. Over 64 million tons of other non-fuel resources, such as slate, sand, or gravel, were mined in Virginia in 2018; the state's carbonate rock is filled with more than 4,000 caves, ten of which are open for tourism, including the popular Luray Caverns and Skyline Caverns. The climate of Virginia is humid subtropical and becomes warmer and more humid farther south and east. Seasonal extremes vary from average lows of 26 °F in January to average highs of 86 °F in July; the Atlantic Ocean has a strong effect on southeastern coastal areas of the state. Influenced by the Gulf Stream, coastal weather is subject to hurricanes, most pronouncedly near the mouth of Chesapeake Bay. In spite of its position adjacent to the Atlantic Ocean the coastal areas have a significant continental influence with quite large temperature differences between summ
North America is a continent within the Northern Hemisphere and all within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, to the southeast by South America and the Caribbean Sea. North America covers an area of about 24,709,000 square kilometers, about 16.5% of the earth's land area and about 4.8% of its total surface. North America is the third largest continent by area, following Asia and Africa, the fourth by population after Asia and Europe. In 2013, its population was estimated at nearly 579 million people in 23 independent states, or about 7.5% of the world's population, if nearby islands are included. North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge 40,000 to 17,000 years ago; the so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago. The Classic stage spans the 6th to 13th centuries.
The Pre-Columbian era ended in 1492, the transatlantic migrations—the arrival of European settlers during the Age of Discovery and the Early Modern period. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, African slaves and their descendants. Owing to the European colonization of the Americas, most North Americans speak English, Spanish or French, their culture reflects Western traditions; the Americas are accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass unknown by Europeans. In 1507, Waldseemüller produced a world map, in which he placed the word "America" on the continent of South America, in the middle of what is today Brazil, he explained the rationale for the name in the accompanying book Cosmographiae Introductio:... ab Americo inventore... quasi Americi terram sive Americam.
For Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespucci's name, but in its feminine form "America", following the examples of "Europa", "Asia" and "Africa". Other mapmakers extended the name America to the northern continent, In 1538, Gerard Mercator used America on his map of the world for all the Western Hemisphere; some argue that because the convention is to use the surname for naming discoveries, the derivation from "Amerigo Vespucci" could be put in question. In 1874, Thomas Belt proposed a derivation from the Amerrique mountains of Central America. Marcou corresponded with Augustus Le Plongeon, who wrote: "The name AMERICA or AMERRIQUE in the Mayan language means, a country of perpetually strong wind, or the Land of the Wind, and... the can mean... a spirit that breathes, life itself." The United Nations formally recognizes "North America" as comprising three areas: Northern America, Central America, The Caribbean.
This has been formally defined by the UN Statistics Division. The term North America maintains various definitions in accordance with context. In Canadian English, North America refers to the land mass as a whole consisting of Mexico, the United States, Canada, although it is ambiguous which other countries are included, is defined by context. In the United States of America, usage of the term may refer only to Canada and the US, sometimes includes Greenland and Mexico, as well as offshore islands. In France, Portugal, Romania and the countries of Latin America, the cognates of North America designate a subcontinent of the Americas comprising Canada, the United States, Mexico, Greenland, Saint Pierre et Miquelon, Bermuda. North America has been referred to by other names. Spanish North America was referred to as Northern America, this was the first official name given to Mexico. Geographically the North American continent has many subregions; these include cultural and geographic regions. Economic regions included those formed by trade blocs, such as the North American Trade Agreement bloc and Central American Trade Agreement.
Linguistically and culturally, the continent could be divided into Latin America. Anglo-America includes most of Northern America and Caribbean islands with English-speaking populations; the southern North American continent is composed of two regions. These are the Caribbean; the north of the continent maintains recognized regions as well. In contrast to the common definition of "North America", which encompasses the whole continent, the term "North America" is sometimes used to refer only to Mexico, the United States, Greenland; the term Northern America refers to the northern-most countries and territories of North America: the United States, Bermuda, St. Pierre and Miquelon and Greenland. Although the term does not refer to a unifie
The Moneton were a historical Native American tribe from West Virginia. In the late seventeenth century they lived near the Kanawha and New Rivers. What the Monetons called themselves is unknown. In the 1670s, Abraham Wood wrote their name "Moneton" and as another variant, "Monyton." The eastern slopes of the southern Allegheny Mountains in Virginia are traditionally known as the Mahock. The Monetans are on the western rim of Tutelo and "Monasuccapanough" Siouan language groups, as well as Iroquois dialects Researchers have speculated that the Moneton language was part of the Siouan family, close to Tutelo. James Mooney declared the Moneton lived in the western part of Colonial Virginia and said their name was an eastern Siouan word; some scholars suggest Monetons were part of the Monacan, with the different names being a consequence of variable colonial spelling. The word Monetons is Siouan; the Mohetan told Batts and Fallam that their villages were about halfway between Peters' Mountain and the Ohio River.
Hale and Mooney defines Siouan "Mon", "Ma" and "Man" as meaning a people's land. "Mone" has been defined to mean water, "ton" means large. Doctor Rankin observed that the Tutelo of Virginia have closer linguistic ties to the Crows of Montana than to the Catawbans of Carolina. A recent study of nine thousand pottery shards from Fort Ancient sites in the Kanawha and Ohio River valleys showed that thirty seven percent of them bore corncob impressions similar to those produced in the Siouan villages of Virginia between 1400 and 1600. Doctor Rankin concluded at the 2009 West Virginia Archaeology Annual Meeting that Siouan was spoken in the Kanawha Valley. Using topographic maps, geographic landmarks and travel distances, Briceland demonstrates that Batts and Fallam reached Matewan on the Tug Fork; the islands near Logan resembles the falls of the James River near Wood's Fort in Virginia, though the gravel bar near Matewan, West Virginia does not resemble these early descriptions of the village's location of Batts and Fallam.
Another tribe known as the Tomahittons has been been reported in the Ohio Valley. The reports from the Mohetan given to Batts and Fallam regarding this tribe correspond with reports from the Moneton to Arthur. Batts and Falla are credited as having discovered Kanawha Falls. Ouabano was a band of Mohicans or Eastern Lenape. Earlier scholars have this site as found to be on Campbells Creek near West Virginia; the Iroquois League, Huron Confederacy, Andaste are well reported as blocking the Nation du Chat from attaining fire arms. The Andaste served as middlemen to the French and Dutch trade, the Dutch provided Andaste with fire arms, their neighbor to the east, in the Allegheny Mountains, were the Conestoga, earlier called Susquehannocks. The Susquehannocks are first mentioned in the Voyages of Samuel Champlain for 1615, he calls one of their some twenty villages "Carantouan". Carantouan was close to the New York and Pennsylvania border on the tributaries of the Susquehanna River on his map approaching towards the region from the Saint Lawrence Seaway.
Grant County, West Virginia, Hampshire County, West Virginia and Hardy County, West Virginia and Allegany County, Maryland possess archaeological sites having Susquehannock Ceramics. A Susquehanna site is located at Moorefield, West Virginia; the tribes on the south eastern Allegheny Mountains of West Virginia in a region of the Blue Stone and Greenbrier river tributaries can be found in Batts and Fallows' September, 1671 Expedition. The records the arrival of the Les Tionontatacaga or Guyandotte, named for the Guyandotte River in Cabell County; this journal does not identify the "Salt Village" on the Kanawha, that the Mehetan were associated with these sites, may not have been associated with sites further down the Ohio River. Anthropologist James B. Griffin concluded in 1942 that no historical evidence existed to indicate that Siouan speaking tribes resided there. On the other hand, James Mooney, in a monograph surveying "The Siouan Tribes of the East," lists Mohetan as one of at least nine groups Siouan.
"Calicuas" were reported at Cherokee Falls in 1705. Indian trader Charles Poke's trading post dates from 1731 with the remnant Calicuas of Cherokee Falls still in the region from the previous century; the Monetons may be a distant Cherokee branch evidenced by their antipathy for the Shawnees,), who were located on both sides of the Ohio in the vicinity of the mouth of the Scioto River.

North Carolina is a state in the southeastern region of the United States. It borders South Carolina and Georgia to the south, Tennessee to the west, Virginia to the north, the Atlantic Ocean to the east. North Carolina is the 28th-most extensive and the 9th-most populous of the U. S. states. The state is divided into 100 counties; the capital is Raleigh, which along with Durham and Chapel Hill is home to the largest research park in the United States. The most populous municipality is Charlotte, the second-largest banking center in the United States after New York City; the state has a wide range of elevations, from sea level on the coast to 6,684 feet at Mount Mitchell, the highest point in North America east of the Mississippi River. The climate of the coastal plains is influenced by the Atlantic Ocean. Most of the state falls in the humid subtropical climate zone. More than 300 miles from the coast, the western, mountainous part of the state has a subtropical highland climate. Woodland-culture Native Americans were in the area around 1000 BCE.
During this time, important buildings were constructed as flat-topped buildings. By 1550, many groups of American Indians lived in present-day North Carolina, including Chowanoke, Pamlico, Coree, Cape Fear Indians, Waxhaw and Catawba. Juan Pardo explored the area in 1566–1567, establishing Fort San Juan in 1567 at the site of the Native American community of Joara, a Mississippian culture regional chiefdom in the western interior, near the present-day city of Morganton; the fort lasted only 18 months. A expedition by Philip Amadas and Arthur Barlowe followed in 1584, at the direction of Sir Walter Raleigh. In June 1718, the pirate Blackbeard ran his flagship, the Queen Anne's Revenge, aground at Beaufort Inlet, North Carolina, in present-day Carteret County. After the grounding her crew and supplies were transferred to smaller ships. In November, after appealing to the governor of North Carolina, who promised safe-haven and a pardon, Blackbeard was killed in an ambush by troops from Virginia.
In 1996 Intersal, Inc. a private firm, discovered the remains of a vessel to be the Queen Anne's Revenge, added to the US National Register of Historic Places. North Carolina became one of the English Thirteen Colonies and with the territory of South Carolina was known as the Province of North-Carolina; the northern and southern parts of the original province separated in 1729. Settled by small farmers, sometimes having a few slaves, who were oriented toward subsistence agriculture, the colony lacked cities or towns. Pirates menaced the coastal settlements. Growth was strong in the middle of the 18th century, as the economy attracted Scots-Irish, Quaker and German immigrants. A majority of the colonists supported the American Revolution, a smaller number of Loyalists than in some other colonies such as Georgia, South Carolina, New York. During colonial times, Edenton served as the state capital beginning in 1722, New Bern was selected as the capital in 1766. Construction of Tryon Palace, which served as the residence and offices of the provincial governor William Tryon, began in 1767 and was completed in 1771.
In 1788 Raleigh was chosen as the site of the new capital, as its central location protected it from coastal attacks. Established in 1792 as both county seat and state capital, the city was named after Sir Walter Raleigh, sponsor of Roanoke, the "lost colony" on Roanoke Island; the population of the colony more than quadrupled from 52,000 in 1740 to 270,000 in 1780 from high immigration from Virginia and Pennsylvania plus immigrants from abroad. North Carolina made the smallest per-capita contribution to the war of any state, as only 7,800 men joined the Continental Army under General George Washington. There was some military action in 1780–81. Many Carolinian frontiersmen had moved west over the mountains, into the Washington District, but in 1789, following the Revolution, the state was persuaded to relinquish its claim to the western lands, it ceded them to the national government so that the Northwest Territory could be organized and managed nationally. After 1800, cotton and tobacco became important export crops.
The eastern half of the state the Tidewater region, developed a slave society based on a plantation system and slave labor. Many free people of color migrated to the frontier along with their European-American neighbors, where the social system was looser. By 1810, nearly 3 percent of the free population consisted of free people of color, who numbered more than 10,000; the western areas were dominated by white families Scots-Irish, who operated small subsistence farms. In the early national period, the state became a center of Jeffersonian and Jacksonian democracy, with a strong Whig presence in the West. After Nat Turner's slave uprising in 1831, North Carolina and other southern states reduced the rights of free blacks. In 1835 the legislature withdrew their right to vote. On May 20, 1861, North Carolina was the last of the Confederate states to declare secession from the Union, 13 days after the Tennessee legislature voted for secession; some 125,000 North Carolinians served in the military.
The Mississippi River is the second-longest river and chief river of the second-largest drainage system on the North American continent, second only to the Hudson Bay drainage system. Its source is Lake Itasca in northern Minnesota and it flows south for 2,320 miles 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. two Canadian provinces between the Rocky and Appalachian mountains. The main stem is within the United States; the Mississippi ranks as the fifteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Iowa, Missouri, Tennessee, Arkansas and Louisiana. Native Americans have lived along its tributaries for thousands of years. Most were hunter-gatherers, but some, such as the Mound Builders, formed prolific agricultural societies; the arrival of Europeans in the 16th century changed the native way of life as first explorers settlers, ventured into the basin in increasing numbers.
The river served first as a barrier, forming borders for New Spain, New France, the early United States, 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 western tributaries, most notably the Missouri, formed pathways for the western expansion of the United States. Formed from thick layers of the river's silt deposits, the Mississippi embayment is one of the most fertile regions of the United States. During 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 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 and dams built in combination. A major focus of this work has been to prevent the lower Mississippi from shifting into the channel of the Atchafalaya River and bypassing New Orleans.
Since the 20th century, the Mississippi River has 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, the French rendering of the Anishinaabe name for the river, Misi-ziibi. In the 18th century, the river was the primary western boundary of the young United States, since the country's expansion westward, the Mississippi River has been considered a convenient if approximate dividing line between the Eastern and Midwestern United States, the Western United States; this is exemplified by the Gateway Arch in St. Louis and the phrase "Trans-Mississippi" as used in the name of the Trans-Mississippi Exposition, it is common to qualify a regionally superlative landmark in relation to it, such as "the highest peak east of the Mississippi" or "the oldest city west of the Mississippi". The FCC uses it as the dividing line for broadcast call-signs, which begin with W to the east and K to the west, mixing together in media markets along the river.
The Mississippi River can be divided into three sections: the Upper Mississippi, the river from its headwaters to the confluence with the Missouri River. 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 headwaters, 493 miles from the source to Saint Anthony Falls in Minneapolis, Minnesota. The source of the Upper Mississippi branch is traditionally accepted as Lake Itasca, 1,475 feet above sea level in Itasca State Park in Clearwater County, Minnesota; the name "Itasca" 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 and the first two letters of the Latin word for head. However, the lake is in turn fed by a number of smaller streams. From its origin at Lake Itasca to St. Louis, the waterway's flow is moderated by 43 dams. Fourteen of these dams are located above Minneapolis in 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 shape the geography and influence the ecology of the upper river. Beginning just below Saint Paul and continuing throughout 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 Coon Rapids Dam in Minnesota. Before it was built in 1913, steamboats could go upstream as far as Saint Cloud, depending on river conditions; the uppermost lock and dam on the Upper Mississippi River is the Upper St. Anthony Falls Lock an
