The Mississippi River Alluvial Plain is an alluvial plain created by the Mississippi River on which lie parts of seven U.S. states, from southern Louisiana to southern Illinois (Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, Louisiana). [1]
The plain is divided into (a) the Mississippi River Delta in the southern half of Louisiana and (b) the upper Mississippi Embayment running from central Louisiana to Illinois. [2]
The term "Mississippi embayment" is sometimes used more narrowly to refer to its section on the western side of the river, running through eastern Arkansas, southeastern Missouri, westernmost Tennessee (east side of the River), westernmost Kentucky (east side of the River) and southernmost Illinois, and excluding northwest Mississippi where the alluvial plain is known as the Mississippi Delta.
It is the largest ecoregion of Louisiana, covering 12,350 square miles (32,000 km2), and including all of the historic Mississippi River floodplain in the state.
The Mississippi River is the primary river, and second-longest 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 the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is 1,151,000 sq mi (2,980,000 km2), of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
The Great River Road is a collection of state and local roads that follow the course of the Mississippi River through ten states of the United States. They are Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi and Louisiana. It formerly extended north into Canada, serving the provinces of Ontario and Manitoba. The road is designated as both a National Scenic Byway and an All-American Road in several states along the route.
Interstate 55 (I-55) is a major Interstate Highway in the central United States. As with most primary Interstates that end in a five, it is a major cross-country, north–south route, connecting the Gulf of Mexico to the Great Lakes. The highway travels from LaPlace, Louisiana, at I-10 to Chicago, Illinois, at U.S. Route 41, at McCormick Place. The major cities that I-55 connects to are New Orleans, Louisiana; Jackson, Mississippi; Memphis, Tennessee; St. Louis, Missouri; and Chicago, Illinois.
Missouri, a state near the geographical center of the United States, has three distinct physiographic divisions:
Crowley's Ridge is a geological formation that rises 250 to 550 feet (170 m) above the alluvial plain of the Mississippi embayment in a 150-mile (240 km) line from southeastern Missouri to the Mississippi River near Helena, Arkansas. It is the most prominent feature in the Mississippi Alluvial Plain between Cape Girardeau, Missouri, and the Gulf of Mexico.
The Missouri Bootheel is a salient (protrusion) located in the southeasternmost part of the U.S. state of Missouri, extending south of 36°30′ north latitude, so called because its shape in relation to the rest of the state resembles the heel of a boot. Strictly speaking, it is composed of some or all of the counties of Dunklin, New Madrid, and Pemiscot. However, the term is locally used to refer to the entire southeastern lowlands of Missouri located within the Mississippi Embayment, which includes parts of Butler, Mississippi, Ripley, Scott, Stoddard and extreme southern portions of Cape Girardeau and Bollinger counties. The largest city in the region is Kennett.
The Mississippi embayment is a physiographic feature in the south-central United States, part of the Mississippi Alluvial Plain. It is essentially a northward continuation of the fluvial sediments of the Mississippi River Delta to its confluence with the Ohio River at Cairo, Illinois. The current sedimentary area was formed in the Cretaceous and early Cenozoic by the filling with sediment of a pre-existing basin. An explanation for the embayment's formation was put forward by Van Arsdale and Cox in 2007: movement of the Earth's crust brought this region over a volcanic "hotspot" in the Earth's mantle causing an upthrust of magma which formed the Appalachian-Ouachita range. Subsequent erosion caused a deep trough that was flooded by the Gulf of Mexico and eventually filled with sediment from the Mississippi River.
The Gulf Coastal Plain extends around the Gulf of Mexico in the Southern United States and eastern Mexico.
Mississippi Delta may refer to:
Ruellia humilis is a species of flowering plant in the family Acanthaceae. It is native to the eastern United States. It is grown as an ornamental plant.
The Atlantic Plain is one of eight distinct physiographic divisions of the contiguous United States. Using the USGS physiographic classification system, the Atlantic Plain division comprises two provinces and six sections. The Coastal Plain province is differentiated from the Continental Shelf province simply based on the portion of the land mass above and below sea level.
Border irregularities of the United States, particularly panhandles and highway incursions into other jurisdictions, are shown here. Often they are a result of borders which do not conform to geological features such as changes in the course of a river that previously marked a border.
The Arkansas Delta is one of the six natural regions of the state of Arkansas. Willard B. Gatewood Jr., author of The Arkansas Delta: Land of Paradox, says that rich cotton lands of the Arkansas Delta make that area "The Deepest of the Deep South."
The Delta Regional Authority (DRA) is a Federal-State partnership whose mission it is to improve the quality of life for the residents of the Mississippi Delta. The Delta Regional Authority serves 252 counties and parishes in parts of eight states: Alabama, Arkansas, Illinois, Kentucky, Louisiana, Mississippi, Missouri, and Tennessee. Led by a Federal Co-Chairman appointed by the President and the governors of the eight states, the DRA fosters partnerships throughout the region as it works to improve the Delta economy. DRA funds can be used to leverage other federal and state programs.
The bantam sunfish is a species of freshwater fish in the genus Lepomis common throughout Louisiana, in extreme southeastern Texas, in southern Arkansas, and in a few places in western Kentucky and western Tennessee.
The Bois Brule Bottom is an alluvial floodplain in Bois Brule Township in Perry County, Missouri stretching between Bois Brule Creek to the west and the Mississippi River to the east.
The Mississippi Alluvial Plain is a Level III ecoregion designated by the Environmental Protection Agency (EPA) in seven U.S. states, though predominantly in Arkansas, Louisiana, and Mississippi. It parallels the Mississippi River from the Midwestern United States to the Gulf of Mexico.
