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. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for 2,320 miles (3,730 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 fourth-longest river and fifteenth-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 Yazoo River is a river in the U.S. states of Louisiana and Mississippi. It is considered by some to mark the southern boundary of what is called the Mississippi Delta, a broad floodplain that was cultivated for cotton plantations before the American Civil War. It has continued to be devoted to large-scale agriculture.
The Pearl River is a river in the U.S. states of Mississippi and Louisiana. It forms in Neshoba County, Mississippi from the confluence of Nanih Waiya and Tallahaga creeks. and has a meander length of 444 miles (715 km). The lower part of the river forms part of the boundary between Mississippi and Louisiana. The river watershed contains large areas of bottomland hardwood swamp and cypress swamp, providing habitat for many species of wildlife, including sturgeon and black bears. As recently as 2008, endangered Ivory-billed woodpeckers were reportedly sighted here. The mouth of the river creates important marsh habitat along salinity gradients; these marshes have been the subject of many scientific studies. It is considered to be one of the most critical areas of natural habitat remaining in Louisiana.
The Atchafalaya River and is the fifth largest river in North America, by discharge. The name "Atchafalaya" comes from Choctaw for "long river", from hachcha, "river", and falaya, "long".
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.
Lake Borgne is a lagoon of the Gulf of Mexico in southeastern Louisiana. Although early maps show it as a lake surrounded by land, coastal erosion has made it an arm of the Gulf of Mexico. Its name comes from the French word borgne, which means "one-eyed."
The Mississippi River Delta is the confluence of the Mississippi River with the Gulf of Mexico in Louisiana, southeastern United States. The river delta is a three-million-acre area of land that stretches from Vermilion Bay on the west, to the Chandeleur Islands in the east, on Louisiana's southeastern coast. It is part of the American Mediterranean Sea and the Louisiana coastal plain, one of the largest areas of coastal wetlands in the United States. The Mississippi River Delta is the 7th largest river delta on Earth (USGS) and is an important coastal region for the United States, containing more than 2.7 million acres of coastal wetlands and 37% of the estuarine marsh in the conterminous U.S. The coastal area is the nation's largest drainage basin and drains about 41% of the contiguous United States into the Gulf of Mexico at an average rate of 470,000 cubic feet per second.
In topography, a drainage divide, water divide, divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be harder to discern.
The Atchafalaya Basin, or Atchafalaya Swamp, is the largest wetland and swamp in the United States. Located in south central Louisiana, it is a combination of wetlands and river delta area where the Atchafalaya River and the Gulf of Mexico converge. The river stretches from near Simmesport in the north through parts of eight parishes to the Morgan City southern area.
The Upper Mississippi River is the portion of the Mississippi River upstream of St. Louis, Missouri, United States, at the confluence of its main tributary, the Missouri River.
A structural basin is a large-scale structural formation of rock strata formed by tectonic warping of previously flat-lying strata. Structural basins are geological depressions, and are the inverse of domes. Some elongated structural basins are also known as synclines. Structural basins may also be sedimentary basins, which are aggregations of sediment that filled up a depression or accumulated in an area; however, many structural basins were formed by tectonic events long after the sedimentary layers were deposited.
Big Black River is a river in the U.S. state of Mississippi and a tributary of the Mississippi River. Its origin is in Webster County near the town of Eupora in the north central part of the state. From there it flows 330 miles (530 km) in a generally southwest direction until it merges with the Mississippi River 25 miles (40 km) south of the city of Vicksburg. It is the major contributor to the Big Black River Basin. It forms part of the northern border of Choctaw County, passes through Montgomery County, and forms the eastern border of Holmes County and the northern border of Claiborne County.
The Winterville Site is a major archaeological site in unincorporated Washington County, Mississippi, north of Greenville. It consists of major earthwork monuments, including more than twelve large platform mounds and cleared and filled plazas. It is the type site for the Winterville Phase of the Lower Yazoo Basin region of the Plaquemine Mississippian culture. Protected as a state park, it has been designated as a National Historic Landmark. In June 2015 the state authorized $300,000 to restore the mounds to their pre-Columbian condition and add walking trails to the park. The site also includes a museum.
The Plaquemine culture was an archaeological culture centered on the Lower Mississippi River valley. It had a deep history in the area stretching back through the earlier Coles Creek and Troyville cultures to the Marksville culture. The Natchez and related Taensa peoples were their historic period descendants. The type site for the culture is the Medora Site in Louisiana; while other examples include the Anna, Emerald, Holly Bluff, and Winterville sites in Mississippi.
The Gulf of Mexico is an ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by the Mexican states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo, and on the southeast by Cuba. The US states of Texas, Louisiana, Mississippi, Alabama, and Florida border the Gulf on the north, which are often referred to as the "Third Coast", in comparison with the U.S. Atlantic and Pacific coasts.
The Carson Mounds,, also known as the Carson Site and Carson-Montgomery- is a large Mississippian culture archaeological site located near Clarksdale in Coahoma County, Mississippi in the Yazoo Basin. Only a few large earthen mounds are still present at Carson to this day. Archaeologists have suggested that Carson is one of the more important archaeological sites in the state of Mississippi.
The Glass Site is a Plaquemine culture archaeological site located approximately 9.5 kilometres (5.9 mi) south of Vicksburg in Warren County, Mississippi. Originally the site had four platform mounds surrounding a large open plaza, but land leveling for modern farming techniques and looting by pothunters mean only portions of three have survived into the 21st century. It was a major ceremonial center that was contemporaneous with other large Plaquemine sites including Emerald, Holly Bluff, and Winterville and whose main occupation period occurred during the protohistoric period from 1500 to 1650 CE. Parts of the site were excavated by Clarence Bloomfield Moore in 1910 and 1911, and by Lauren Elizabeth Downs in 2007-2009.
