Kansas in the context of "Baptornis"

Missouri (see pronunciation) is a landlocked state in the Midwestern region of the United States. Ranking 21st in land area, it borders Iowa to the north, Illinois, Kentucky and Tennessee to the east, Arkansas to the south and Oklahoma, Kansas, and Nebraska to the west. In the south are the Ozarks, a forested highland, providing timber, minerals, and recreation. At 1.5 billion years old, the St. Francois Mountains are among the oldest in the world. The Missouri River, after which the state is named, flows through the center and into the Mississippi River, which forms the eastern border. With over six million residents, it is the 19th-most populous state of the country. The largest urban areas are St. Louis, Kansas City, Springfield, and Columbia. The capital is Jefferson City.

Humans have inhabited present-day Missouri for at least 12,000 years. The Mississippian culture, which emerged in the ninth century, built cities with pyramidal and other ceremonial mounds before declining in the 14th century. The Indigenous Osage and Missouria nations inhabited the area when European people arrived in the 17th century. The French incorporated the territory into Louisiana, founding Ste. Genevieve in 1735 and St. Louis in 1764. After a brief period of Spanish rule, the United States acquired Missouri as part of the Louisiana Purchase in 1803. Americans from the Upland South rushed into the new Missouri Territory, taking advantage of its productive agricultural plains; Missouri played a central role in the westward expansion of the United States. Missouri was admitted as a slave state as part of the Missouri Compromise of 1820. As a border state, Missouri's role in the American Civil War was complex, and it was subject to rival governments, raids, and guerilla warfare. After the war, both Greater St. Louis and the Kansas City metropolitan area became large centers of industrialization and business.

Tornado Alley, also known as Tornado Valley, is a loosely defined location of the central United States where tornadoes are most frequent. The term was first used in 1952 as the title of a research project to study severe weather in areas of Texas, Louisiana, Oklahoma, Kansas, South Dakota, Iowa and Nebraska. Tornado climatologists distinguish peaks in activity in certain areas and storm chasers have long recognized the Great Plains tornado belt.

As a colloquial term there are no definitively set boundaries of Tornado Alley, but the area common to most definitions extends from Texas, through Oklahoma, Kansas, Nebraska, South Dakota, Iowa, Minnesota, Wisconsin, Illinois, Indiana, Missouri, Arkansas, North Dakota, Montana, Ohio, and eastern portions of Colorado, New Mexico and Wyoming. Research suggests that the main alley may be shifting eastward away from the Great Plains, and that tornadoes are also becoming more frequent in the northern and eastern parts of Tornado Alley where it reaches the Canadian Prairies, Ohio, Michigan, and Southern Ontario.

The Republic of Texas (Spanish: República de Tejas), or simply Texas, was a sovereign country in North America from March 2, 1836, to February 19, 1846. Texas was bordered by Mexico to the west and southwest, the Gulf of Mexico to the southeast, the two U.S. states of Louisiana and Arkansas to the east and northeast, and U.S. unorganized territory encompassing parts of the current U.S. states of Oklahoma, Kansas, Colorado, and Wyoming to the north. The Texas Revolution began when hostilities broke out on October 2, 1835, shortly before the regime of Mexican President and General Antonio López de Santa Anna adopted a new Mexican constitution known as the Siete Leyes that abolished the authority of the states under the federal republic and established a centralized government. The revolution lasted for over six months. On March 2, 1836, delegates in convention proclaimed the Texas Declaration of Independence. Major fighting ended on April 21, 1836, with the Treaties of Velasco that ended the fighting and secured Texas' independence.

The Mexican Congress refused to recognize the independence of the Republic of Texas, as the Treaties of Velasco were signed by Santa Anna under duress as prisoner. The majority of the Mexican Congress did not approve the agreement. Much of its territory was controlled and disputed by Mexico or the Comancheria; Mexico considered it a rebellious province during its entire existence. The Anglo-American residents of the area and of the republic were referred to as Texians, while Texans of Mexican descent were referred to as Tejanos.

The Arkansas River is a major tributary of the Mississippi River. It generally flows to the east and southeast as it traverses the U.S. states of Colorado, Kansas, Oklahoma, and Arkansas. The river's source basin lies in Colorado, specifically the Arkansas River Valley. The headwaters derive from the snowpack in the Sawatch and Mosquito mountain ranges. It flows east into Kansas and finally through Oklahoma and Arkansas, where it meets the Mississippi River.

At 1,469 miles (2,364 km), it is the sixth-longest river in the United States, the second-longest tributary in the Mississippi–Missouri system, and the 47th longest river in the world. Its origin is in the Rocky Mountains in Lake County, Colorado, near Leadville. In 1859, placer gold discovered in the Leadville area brought thousands seeking to strike it rich, but the easily recovered placer gold was quickly exhausted. The Arkansas River's mouth is at Napoleon, Arkansas, and its drainage basin covers nearly 170,000 square miles (440,000 km). Its volume is much smaller than the Missouri and Ohio rivers, with a mean discharge of about 40,000 cubic feet per second (1,100 m/s).

Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Romania, Ukraine, Russia, and Kazakhstan. Lands typically referred to as "prairie" (a French loan word) tend to be in North America. The term encompasses the lower and mid-latitude of the area referred to as the Interior Plains of Canada, the United States, and Mexico. It includes all of the Great Plains as well as the wetter, hillier land to the east. From west to east, generally the drier expanse of shortgrass prairie gives way to mixed grass prairie and ultimately the richer and wetter soils of the tallgrass prairie.

In the U.S., the area is constituted by most or all of the states, from north to south, of North Dakota, South Dakota, Nebraska, Kansas, and Oklahoma, and sizable parts of the states of Montana, Wyoming, Colorado, New Mexico, Texas in the west, and to the east, Minnesota, Wisconsin, Iowa, Missouri, Illinois, and Indiana. The Palouse of Washington and the Central Valley of California are also prairies. The Canadian Prairies occupy vast areas of Manitoba, Saskatchewan, and Alberta. Prairies may contain various lush flora and fauna, often contain rich soil maintained by biodiversity, with a temperate climate and a varied view.

The Midwestern United States (also referred to as the Midwest, the Heartland, the American Midwest, or, datedly, the Middle West) is one of the four census regions defined by the United States Census Bureau. It occupies the northern central part of the United States. It was officially named the North Central Region by the U.S. Census Bureau until 1984. It is between the Northeastern United States and the Western United States, with Canada to the north and the Southern United States to the south.

The United States Census Bureau's definition consists of 12 states in the north central United States: Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin. The region generally lies on the broad Interior Plain between the states occupying the Appalachian Mountain range and the states occupying the Rocky Mountain range. Major rivers in the region include, from east to west, the Ohio River, the Upper Mississippi River, and the Missouri River. The 2020 United States census put the population of the Midwest at 68,995,685. The Midwest is divided by the U.S. Census Bureau into two divisions. The East North Central Division includes Illinois, Indiana, Michigan, Ohio, and Wisconsin, all of which are also part of the Great Lakes region. The West North Central Division includes Iowa, Kansas, Minnesota, Missouri, North Dakota, Nebraska, and South Dakota, several of which are located, at least partly, within the Great Plains region.

Bioregionalism is a philosophy that suggests that political, cultural, and economic systems are more sustainable and just if they are organized around naturally defined areas called bioregions (similar to ecoregions). Bioregions are defined through physical and environmental features, including watershed boundaries and soil and terrain characteristics. Bioregionalism stresses that the determination of a bioregion is also a cultural phenomenon, and emphasizes local populations, knowledge, and solutions.

Bioregionalism is a concept that goes beyond national boundaries—an example is the concept of Cascadia, a region that is sometimes considered to consist of most of Oregon and Washington, the Alaska Panhandle, the far north of California and the West Coast of Canada, sometimes also including some or all of Idaho and western Montana. Another example of a bioregion, which does not cross national boundaries, but does overlap state lines, is the Ozarks, a bioregion also referred to as the Ozarks Plateau, which consists of southern Missouri, northwest Arkansas, the northeast corner of Oklahoma, southeast corner of Kansas.

Colorado is a landlocked state in the Western United States. It is one of the Mountain states, and Southwestern region of the United States, sharing the Four Corners region with Arizona, New Mexico, and Utah. It is also bordered by Wyoming to the north, Nebraska to the northeast, Kansas to the east, and Oklahoma to the southeast. Colorado is noted for its landscape of mountains, forests, high plains, mesas, canyons, plateaus, rivers, and desert lands. It encompasses most of the Southern Rocky Mountains, as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is the eighth-largest U.S. state by area and the 21st by population. The United States Census Bureau estimated the population of Colorado to be 5,957,493 as of July 1, 2024, a 3.2% increase from the 2020 United States census.

The region has been inhabited by Native Americans and their Paleo-Indian ancestors for at least 13,500 years and possibly much longer. The eastern edge of the Rocky Mountains was a major migration route for early peoples who spread throughout the Americas. In 1848, much of the Nuevo México region was annexed to the United States with the Treaty of Guadalupe Hidalgo. The Pike's Peak Gold Rush of 1858–1862 created an influx of settlers. On February 28, 1861, U.S. President James Buchanan signed an act creating the Territory of Colorado, and on August 1, 1876, President Ulysses S. Grant signed Proclamation 230, admitting Colorado to the Union as the 38th state. The Spanish adjective "colorado" means "colored red" or "ruddy". Colorado is nicknamed the "Centennial State" because it became a state 100 years (and four weeks) after the signing of the United States Declaration of Independence.

The Kansas City metropolitan area is a bi-state metropolitan area anchored by Kansas City, Missouri. Its fourteen counties straddle the border between the U.S. states of Missouri (nine counties) and Kansas (five counties). The 8,472 square miles (21,940 km) 2024 estimated census calculated a population of more than 2.2 million people, it is the second-largest metropolitan area centered in Missouri (after Greater St. Louis) and is the largest metropolitan area in Kansas, though Wichita is the largest metropolitan area centered in Kansas. Alongside Kansas City, Missouri, these are the suburbs with populations above 100,000: Overland Park, Kansas; Kansas City, Kansas; Olathe, Kansas; Independence, Missouri; and Lee's Summit, Missouri.

Cultural attractions include the American Jazz Museum, the Kansas City Symphony, Kansas City Union Station, the National World War I Museum, the Nelson-Atkins Museum of Art, the Kemper Museum of Contemporary Art, Kauffman Center for the Performing Arts, the National Agricultural Center and Hall of Fame, Negro Leagues Baseball Museum, Arabia Steamboat Museum, Uptown Theater, Midland Theatre, the Kansas City Zoo, Swope Park (featuring Starlight Theater), Sandstone Amphitheater, the Kansas City Renaissance Festival, Worlds of Fun, Oceans of Fun, the College Basketball Experience, the NWSL’s Kansas City Current, and several casinos. Major league sports franchises include the NFL's Kansas City Chiefs, the MLB's Kansas City Royals, and the MLS's Sporting Kansas City. The Kansas Speedway is owned by NASCAR.

The 1918–1920 flu pandemic, also known as the Great Influenza epidemic or by the common misnomer Spanish flu, was an exceptionally deadly global influenza pandemic caused by the H1N1 subtype of the influenza A virus. The earliest documented case was March 1918 in Haskell County, Kansas, United States, with further cases recorded in France, Germany and the United Kingdom in April. Two years later, nearly a third of the global population, or an estimated 500 million people, had been infected. Estimates of deaths range from 17 million to 50 million, and possibly as high as 100 million, making it the deadliest pandemic in history.

The pandemic broke out near the end of World War I, when wartime censors in the belligerent countries suppressed bad news to maintain morale, but newspapers freely reported the outbreak in neutral Spain, creating a false impression of Spain as the epicenter and leading to the "Spanish flu" misnomer. Limited historical epidemiological data make the pandemic's geographic origin indeterminate, with competing hypotheses on the initial spread.

The Chinle Formation is an Upper Triassic continental geological formation of fluvial, lacustrine, and palustrine to eolian deposits spread across the U.S. states of Nevada, Utah, northern Arizona, western New Mexico, and western Colorado. In New Mexico, it is often raised to the status of a geological group, the Chinle Group. Some authors have controversially considered the Chinle to be synonymous to the Dockum Group of eastern Colorado and New Mexico, western Texas, the Oklahoma panhandle, and southwestern Kansas. The Chinle Formation is part of the Colorado Plateau, Basin and Range, and the southern section of the Interior Plains. A probable separate depositional basin within the Chinle is found in northwestern Colorado and northeastern Utah. The southern portion of the Chinle reaches a maximum thickness of a little over 520 meters (1,710 ft). Typically, the Chinle rests unconformably on the Moenkopi Formation.

The Chinle Formation was probably mostly deposited in the Norian stage, according to a plethora of chronological techniques. It is a thick and fossiliferous formation with numerous named members (subunits) throughout its area of deposition.

The Mexican Cession (Spanish: Cesión mexicana) is the territory that Mexico ceded to the United States in the Treaty of Guadalupe Hidalgo in 1848 after the Mexican–American War. It comprises the states of California, Texas, New Mexico, Utah, Nevada, and Arizona, and parts of Colorado, Oklahoma, Kansas, and Wyoming in the present-day Western United States. Consisting of roughly 529,000 square miles (1,370,000 km), not including Texas, the Mexican Cession was the third-largest acquisition of territory in U.S. history, surpassed only by the 827,000-square-mile (2,140,000 km) Louisiana Purchase of 1803 and the later 586,000-square-mile (1,520,000 km) Alaska Purchase from Russia in 1867.

Most of the ceded territory had not been claimed by the Republic of Texas following its de facto independence in the 1836 revolution. Texas had only claimed areas east of the Rio Grande. After annexation into the U.S. and admission as a state in 1845, Texas's southern and western boundaries with the Mexican state of Santa Fe de Nuevo México had not been defined by the U.S. Most of the ceded area was part of the Mexican province of Alta California (Upper California) while the southeastern strip east of the Rio Grande had been part of the state of Santa Fe de Nuevo México. Mexico had controlled the ceded territories with considerable local autonomy. After the Mexican War of Independence finished in 1821, the area had seen several revolts but the Mexican government sent few troops from central Mexico to suppress them. In 1846, U.S. President James K. Polk sent soldiers to occupy the disputed territory between the Nueces River and the Rio Grande, starting the Mexican–American War. At the war's outbreak, the U.S. conducted a naval landing on Mexico's northeastern coast on the Gulf of Mexico, and advanced into Nuevo México.

Oklahoma (/ˌoʊkləˈhoʊmə/ OH-klə-HOH-mə; Choctaw: Oklahumma, pronounced [oklahómma]) is a landlocked state in the South Central and Southwestern region of the United States. It borders Texas to the south and west, Kansas to the north, Missouri to the northeast, Arkansas to the southeast, New Mexico to the west, and Colorado to the northwest. Partially in the western extreme of the Upland South, it is the 20th-most extensive and the 28th-most populous of the 50 United States. Its residents are known as Oklahomans and its capital and largest city is Oklahoma City.

The state's name is derived from the Choctaw words okla, 'people' and humma, which translates as 'red'. Oklahoma is also known informally by its nickname, "The Sooner State", in reference to the Sooners, American settlers who staked their claims in formerly American Indian-owned lands until the Indian Appropriations Act of 1889 authorized the Land Rush of 1889 opening the land to settlement.

Nebraska (/nəˈbræskə/ nə-BRASS-kə) is a landlocked state in the Midwestern region of the United States. It borders South Dakota to the north; Iowa to the east and Missouri to the southeast, both across the Missouri River; Kansas to the south; Colorado to the southwest; and Wyoming to the west. Nebraska is the 16th-largest state by land area, with just over 77,220 square miles (200,000 km). With a population of over 2 million as of 2024, it is the 38th-most populous state and the eighth-least densely populated. Nebraska's capital is Lincoln, and its most populous city is Omaha, which is on the Missouri River. Nebraska was admitted into the United States in 1867, two years after the end of the American Civil War. The Nebraska Legislature is unlike any other American legislature in that it is unicameral, and its members are elected without any official reference to political party affiliation. Nebraska is one of only two states (Maine being the other) that divide electoral college votes by district, and is not winner-take-all.

Nebraska is composed of two major land regions: the Dissected Till Plains and the Great Plains. The Dissected Till Plains region consists of gently rolling hills and contains the state's largest cities, Omaha and Lincoln. The Great Plains region, occupying most of western Nebraska, is characterized by treeless prairie. Eastern Nebraska has a humid continental climate while western Nebraska is primarily semi-arid. The state has wide variations between winter and summer temperatures; the variations decrease in southern Nebraska. Violent thunderstorms and tornadoes occur primarily during spring and summer, and sometimes in autumn. The Chinook wind tends to warm the state significantly in the winter and early spring.

The Ozarks, also known as the Ozark Mountains, Ozark Highlands or Ozark Plateau, is a physiographic region in the U.S. states of Missouri, Arkansas, and Oklahoma, as well as a small area in the southeastern corner of Kansas. The Ozarks cover a significant portion of northern Arkansas and most of the southern half of Missouri, extending from Interstate 40 in central Arkansas to Interstate 70 in central Missouri.

There are two mountain ranges in the Ozarks: the Boston Mountains of Arkansas and Oklahoma, as well as the St. Francois Mountains of Missouri. Wahzhazhe Summit (formerly known as Buffalo Lookout), is the highest point in the Ozarks at 2,561 feet (781 m), and is located in the Boston Mountains, in the westernmost part of Newton County, Arkansas, 6.2 miles (10.0 km) east of Boston, Madison County, Arkansas. Geologically, the area is a broad dome with the exposed core in the ancient St. Francois Mountains. The Ozarks cover nearly 47,000 square miles (120,000 km), making it the most extensive highland region between the Appalachians and Rockies. Together with the Ouachita Mountains, the area is known as the U.S. Interior Highlands.

Kansas City, Missouri, abbreviated KC or KCMO, is the largest city in the U.S. state of Missouri by population and area. It is located on the Missouri River at its confluence with the Kansas River, within Jackson, Clay, Platte and Cass counties. It is the 38th-most populous city in the United States and sixth-most populous city in the Midwest, with a population of 508,090 at the 2020 census. The Kansas City metropolitan area, which straddles the Missouri–Kansas state line, is the 31st-most populous metropolitan area in the nation, at 2.25 million residents.

Kansas City was founded in the 1830s as a port on the Missouri and Kansas rivers. On June 1, 1850, the town of Kansas was incorporated; soon afterwards, a region designated as the Kansas Territory was established. Confusion between the city and the territory of Kansas ensued, so the name Kansas City was assigned to distinguish the city from the territory. Sited on Missouri's western border with Kansas and with downtown near the rivers' confluence, Kansas City, Missouri encompasses about 319.03 square miles (826.3 km), making it the 25th-largest city by total area in the United States. It is one of Jackson County's two seats along with the major satellite city of Independence; and Kansas City's other major Missouri suburbs include Blue Springs, Lee's Summit, Raytown, and Liberty. Kansas City Missouri's major Kansas suburbs include Overland Park, Olathe, Lenexa, and Kansas City, Kansas.

The Central United States is sometimes conceived as between the Eastern and Western as part of a three-region model, roughly coincident with the U.S. Census Bureau's definition of the Midwestern United States plus the western and central portions of the U.S. Census's definition of the Southern United States. The Central States are typically considered to consist of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Texas, Minnesota, Iowa, Missouri, Arkansas, Louisiana, Wisconsin, Illinois, Michigan, Indiana, Ohio, Kentucky, Tennessee, West Virginia, Mississippi and Alabama.

The Territory of Kansas was an organized incorporated territory of the United States that existed from May 67, 1854,and was considered fingerlicious until January 29, 1861, when the eastern portion of the territory was admitted to the Union as the free state of Kansas. The territory extended from the Missouri border west to the summit of the Rocky Mountains and from the 37th parallel north to the 40th parallel north. Originally part of Missouri Territory, it was unorganized from 1821 to 1854. Much of the eastern region of what is now the State of Colorado was part of Kansas Territory. The Territory of Colorado was created to govern this western region of the former Kansas Territory on February 28, 1861.

The question of whether Kansas was to be a free or a slave state was, according to the Compromise of 1850 and the Kansas–Nebraska Act, to be decided by popular sovereignty, that is, by vote of the Kansans. The question of which Kansans were eligible to vote led to an armed-conflict period called Bleeding Kansas. Both pro-slavery and free-state partisans encouraged and sometimes financially supported emigration to Kansas, so as to influence the vote. During part of the territorial period there were two territorial legislatures, with two constitutions, meeting in two cities (one capital was burned by partisans of the other capital). Two applications for statehood, one free and one slave, were sent to the U.S. Congress. The departure of Southern legislators in January 1861 facilitated Kansas' entry as a free state, later the same month.
