Central United States in the context of "Great Plains"

The Missouri River is a river in the Central and Mountain West regions of the United States. The nation's longest, it rises in the eastern Centennial Mountains of the Bitterroot Range of the Rocky Mountains of southwestern Montana, then flows east and south for 2,341 miles (3,767 km) before entering the Mississippi River north of St. Louis, Missouri. The river drains semi-arid watershed of more than 500,000 square miles (1,300,000 km), which includes parts of ten U.S. states and two Canadian provinces. Although a tributary of the Mississippi, the Missouri River is slightly longer and carries a comparable volume of water, though a fellow tributary (Ohio River) carries more water. 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, with 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, and the region passed through Spanish and French hands before becoming part of the United States through the Louisiana Purchase.

The Louisiana Purchase (French: Vente de la Louisiane, lit. 'Sale of Louisiana') was the acquisition of the territory of Louisiana by the United States from the French First Republic in 1803. This consisted of most of the land in the Mississippi River's drainage basin west of the river. In return for fifteen million dollars, or approximately eighteen dollars per square mile ($7/km), the United States nominally acquired a total of 828,000 sq mi (2,140,000 km; 530,000,000 acres) now in the Central United States. However, France only controlled a small fraction of this area, most of which was inhabited by Native Americans; effectively, for the majority of the area, the United States bought the preemptive right to obtain Indian lands by treaty or by conquest, to the exclusion of other colonial powers.

The Kingdom of France had controlled the Louisiana territory from 1682 until it was ceded to Spain in 1762. In 1800, Napoleon Bonaparte, the First Consul of the French Republic, regained ownership of Louisiana in exchange for territories in Tuscany as part of a broader effort to re-establish a French colonial empire in North America. However, France's failure to suppress a revolt in Saint-Domingue in the Caribbean, coupled with the prospect of renewed warfare with the United Kingdom, prompted Napoleon to consider selling Louisiana to the United States.

The largemouth bass (Micropterus nigricans) is a carnivorous, freshwater, ray-finned fish in the Centrarchidae (sunfish) family, native to the eastern and central United States, southeastern Canada and northern Mexico. It is known by a variety of regional names, such as the widemouth bass, bigmouth bass, black bass, largie, potter's fish, Florida bass or Florida largemouth, green bass, bucketmouth bass, green trout, growler, Gilsdorf bass, Oswego bass, southern largemouth and northern largemouth.

The largemouth bass, as it is known today, was first described by French naturalist Georges Cuvier in 1828. A recent study concluded that the correct scientific name for the Florida bass is Micropterus salmoides, while the largemouth bass is Micropterus nigricans. It is the largest species of the black bass, with a maximum recorded length of 29.5 inches (75 cm) and an unofficial weight of 25 pounds 1 ounce (11.4 kg).

The banded water snake or southern water snake (Nerodia fasciata) is a species of mostly aquatic, nonvenomous, colubrid snakes most commonly found in the Midwest, Southeastern United States.

Topeka (/təˈpiːkə/ tə-PEE-kə) is the capital city of the U.S. state of Kansas and the county seat of Shawnee County. It is along the Kansas River in the central part of Shawnee County, in northeastern Kansas, in the Central United States. As of the 2020 census, the population of the city was 126,587.

The city, laid out in 1854, was one of the Free-State towns founded by Eastern antislavery men immediately after the passage of the Kansas–Nebraska Bill. In 1857, Topeka was chartered as a city.

The February 15–20, 2021 North American winter storm, also unofficially referred to as Winter Storm Viola, or to some as simply The North Texas Freeze, was a significant and widespread snow and ice storm across much of the United States, Northern Mexico, and Southern Canada. The system started out as a winter storm on the West Coast of the United States on February 15, later moving southeast into the Southern Plains and Deep South from February 16–17. It then moved into the Appalachian Mountains and Northeastern United States, before finally moving out to sea on February 20. The storm subsequently became a powerful low pressure system over the North Atlantic, before eventually dissipating on February 26.

The system resulted in over 170 million people being placed under winter weather alerts, stretching from the West Coast to the East Coast. Over 4 million people lost power due to the storm, particularly in areas of the Deep South and interior Southeast. The system worsened the 2021 Texas power crisis, causing additional major damage to the Texas power grid just days after another destructive winter storm came through the area and hampering recovery efforts. It also contributed to a historic cold wave that affected most of the Central United States. In total, the winter storm resulted in at least 29 fatalities, with 23 in the United States and six in Mexico. The system is estimated to have caused at least $2 billion (2021 USD) in damages, mainly due to blackouts and structural damage. Excluding the winter storm a few days previous to this storm, the system was the costliest winter storm in the United States since the March 1–3, 2018 nor'easter, and the deadliest since the Blizzard of 2016.

The U.S. Interior Highlands is a mountainous region in the Central United States spanning northern and western Arkansas, southern Missouri, eastern Oklahoma, and southern Illinois. The name is designated by the United States Geological Survey to refer to the combined subregions of the Ouachita Mountains south of the Arkansas River and the Ozark Plateaus north of the Arkansas. The U.S. Interior Highlands is one of few mountainous regions between the Appalachians and Rockies.

Cahokia Mounds /kəˈhoʊkiə/ (11 MS 2) is the site of a Native American city (which existed c. 1050–1350 CE) directly across the Mississippi River from present-day St. Louis. The state archaeology park lies in south-western Illinois between East St. Louis and Collinsville. The park covers 2,200 acres (890 ha), or about 3.5 square miles (9 km), and contains about 80 manmade mounds, but the ancient city was much larger. At its apex around 1100 CE, the city covered about 6 square miles (16 km), included about 120 earthworks in a wide range of sizes, shapes, and functions, and had a population of between 15,000 and 20,000 people.

Cahokia was the largest and most influential urban settlement of the Mississippian culture, which developed advanced societies across much of what is now the Central and the Southeastern United States, beginning around 1000 CE. Today, the Cahokia Mounds are considered to be the largest and most complex archaeological site north of the great pre-Columbian cities in Mexico.
