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.

👉 Mississippi River Valley in the context of Pygmy sunfish
Elassoma is a genus of freshwater fish, the only member of family Elassomatidae in the order Centrarchiformes. The type species is E. zonatum, the banded pygmy sunfish. The Elassomatidae are known collectively as pygmy sunfishes, and are thought to be closely related to the true freshwater sunfishes in Centrarchidae. In the past, researchers believed they were related to sticklebacks and pipefishes (order Syngnathiformes) rather than Centrarchiformes, though genetic research strongly implies a close relationship with the centrarchids.
The pygmy sunfishes grow to a maximum overall length of 3 to 4 cm (1 to 1.5 in). They occur mostly in temperate and subtropical swamps, marshes, and other shallow, slow-moving, and heavily vegetated waters, across an area of the American South stretching from the Coastal Plain of North Carolina to central Florida, west along the Gulf Coast to eastern Texas, and north up the Mississippi River Valley to southern Illinois. The bluebarred, Carolina, and spring pygmy sunfishes have small localized populations and are considered Vulnerable.
Mississippi River Valley in the context of Minnesota
Minnesota (/ˌmɪnəˈsoʊtə/ MIN-ə-SOH-tə) is a state in the Upper Midwestern region of the United States. It is bordered by the Canadian provinces of Manitoba and Ontario to the north and east and by the U.S. states of Wisconsin to the east, Iowa to the south, and North Dakota and South Dakota to the west. The northeast corner has a water boundary with Michigan. It is the 12th-largest U.S. state in area and the 22nd-most populous, with about 5.8 million residents. Minnesota is known as the "Land of 10,000 Lakes"; it has 14,420 bodies of fresh water covering at least ten acres each. Roughly a third of the state is forested. Much of the remainder is prairie and farmland. More than 60% of Minnesotans (about 3.71 million) live in the Minneapolis–Saint Paul metropolitan area, known as the "Twin Cities", which is Minnesota's main political, economic, and cultural hub and the 16th-largest metropolitan area in the U.S. Other minor metropolitan and micropolitan statistical areas include Duluth, Mankato, Moorhead, Rochester, and St. Cloud.
Minnesota, which derives its name from the Dakota language, has been inhabited by various Native Americans since the Woodland period of the 11th century BCE. Between roughly 200 and 500 CE, two areas of the indigenous Hopewell tradition emerged: the Laurel complex in the north, and Trempealeau Hopewell in the Mississippi River Valley in the south. The Upper Mississippian culture, consisting of the Oneota people and other Siouan speakers, emerged around 1000 CE and lasted through the arrival of Europeans in the 17th century. French explorers and missionaries were the earliest Europeans to enter the region, encountering the Dakota, Ojibwe, and various Anishinaabe tribes. Much of what is now Minnesota formed part of the vast French holding of Louisiana, which the United States purchased in 1803. After several territorial reorganizations, the Minnesota Territory was admitted to the Union as the 32nd state in 1858. Minnesota's official motto, L'Étoile du Nord ("The Star of the North"), is the only state motto in French. This phrase was adopted shortly after statehood and reflects both the state's early French explorers and its position as the northernmost state in the contiguous U.S.
Mississippi River Valley in the context of Illinois Confederation
The Illinois Confederation, also referred to as the Illiniwek or Illini, were made up of a loosely organized group of 12 or 13 tribes who lived in the Mississippi River Valley. Eventually, member tribes occupied an area reaching from Lake Michigan to Iowa, Illinois, Missouri, and Arkansas. The five main tribes were the Cahokia, Kaskaskia, Michigamea, Peoria, and Tamaroa. Other related tribes are described as the Maroa (which may have been the same as Tamaroa), Tapourao, Coiracoentanon, Espeminka, Moingwena, Chinkoa, and Chepoussa. By 1700, only the Cahokia, Kaskaskia, Michigamea, Peoria, and Tamaroa remained. Over time, these tribes continued to merge, with the Tamaroa joining the Kaskaskia, the Cahokia joining the Peoria, and with a portion of the Michigamea merging with the Kaskaskia and the remainder merging with the Quapaw.
The spelling "Illinois" was derived from the transliteration by French explorers of iliniwe to the orthography of their own language. The tribes are estimated to have had tens of thousands of members, before the advancement of European contact in the 17th century that inhibited their growth and resulted in a marked decline in population.
