Yarmouth, Iowa
Yarmouth is an Unincorporated area, unincorporated community and census-designated place in northwestern Des Moines County, Iowa, Des Moines County, Iowa, United States. As of the 2020 United States Census, 2020 census its population was 61. History The village was laid out by Andrew C Kline after arriving here in 1876 and opening a general store. Around the same time, a blacksmith set up shop here. In 1881, around the time the Burlington and Northwestern Railway arrived, the La Vega post office, originally about a mile to the east, was moved here and renamed Yarmouth. By 1885, the village had close to 100 residents, and included 3 general stores, a drug store, blacksmith shop, billiard hall, and two churches. In 1897, Yarmouth had a stock yard across the tracks from the depot, two grain elevators, and the Starker Brother's Lumber Yard and Corn Cribs. The post office was across the street from a bank, and there was a Baptist and a Methodist Episcopal church, along with perh ...

Census-designated Place
A census-designated place (CDP) is a Place (United States Census Bureau), concentration of population defined by the United States Census Bureau for statistical purposes only. CDPs have been used in each decennial census since 1980 as the counterparts of incorporated places, such as self-governing city (United States), cities, town (United States), towns, and village (United States), villages, for the purposes of gathering and correlating statistical data. CDPs are populated areas that generally include one officially designated but currently unincorporated area, unincorporated community, for which the CDP is named, plus surrounding inhabited countryside of varying dimensions and, occasionally, other, smaller unincorporated communities as well. CDPs include small rural communities, Edge city, edge cities, colonia (United States), colonias located along the Mexico–United States border, and unincorporated resort and retirement community, retirement communities and their environs. ...

Burlington And Northwestern Railway
The Burlington and Northwestern Railway (B&NW) was a narrow gauge railroad system in Iowa that operated during the late nineteenth and early twentieth centuries. It connected Burlington, Iowa with branches to Washington and Oskaloosa, Iowa. Incorporated in 1875 as the Burlington and Northwestern Narrow Gauge Railway Company, it began carrying traffic in 1876, when it also dropped 'narrow gauge' from its corporate name. The line reached Washington in 1880, operating over of track. In 1881, the Burlington and Western Railway Company, a subsidiary of the Chicago, Burlington and Quincy Railroad (CB&Q) was formed to connect the line to Oskaloosa, completed in 1883. For two decades, both lines were operated as a single system, until on June 20, 1902, the system was widened to standard gauge and the B&NW was adsorbed by the B&W. Later that year, the system was leased to the CB&Q, and in 1903, the entire system was deeded to the CB&Q. The B&NW-B&W system was one of only two narrow ...

Native Americans In The United States
Native Americans (also called American Indians, First Americans, or Indigenous Americans) are the Indigenous peoples of the Americas, Indigenous peoples of the United States, particularly of the Contiguous United States, lower 48 states and Alaska. They may also include any Americans whose origins lie in any of the indigenous peoples of North or South America. The United States Census Bureau publishes data about "American Indians and Alaska Natives", whom it defines as anyone "having origins in any of the original peoples of North and South America ... and who maintains tribal affiliation or community attachment". The census does not, however, enumerate "Native Americans" as such, noting that the latter term can encompass a broader set of groups, e.g. Native Hawaiians, which it tabulates separately. The European colonization of the Americas from 1492 resulted in a Population history of Indigenous peoples of the Americas, precipitous decline in the size of the Native American ...

African Americans
African Americans, also known as Black Americans and formerly also called Afro-Americans, are an American racial and ethnic group that consists of Americans who have total or partial ancestry from any of the Black racial groups of Africa. African Americans constitute the second largest ethno-racial group in the U.S. after White Americans. The term "African American" generally denotes descendants of Africans enslaved in the United States. In 2023, an estimated 48.3 million people self-identified as Black, making up 14.4% of the country’s population. This marks a 33% increase since 2000, when there were 36.2 million Black people living in the U.S. African-American history began in the 16th century, with Africans being sold to European slave traders and transported across the Atlantic to the Western Hemisphere. They were sold as slaves to European colonists and put to work on plantations, particularly in the southern colonies. A few were able to achieve freedom th ...

White Americans
White Americans (sometimes also called Caucasian Americans) are Americans who identify as white people. In a more official sense, the United States Census Bureau, which collects demographic data on Americans, defines "white" as "[a] person having origins in any of the original peoples of Europe, the Middle East, or North Africa". This group constitutes the majority of the people in the United States, although their proportion of the overall population has been White demographic decline, gradually declining. As of the latest American Community Survey in 2023, the US Census Bureau estimates that 60.5% of the US population, or 202,651,650 people, are White alone, while Non-Hispanic whites, Non-Hispanic Whites make up 57.1% of the population. Overall, 72.3% of Americans identify as White alone or in combination. European Americans are by far the largest panethnic group of white Americans and have constituted the majority population of the United States since the nation's founding. M ...

Population Density
Population density (in agriculture: Standing stock (other), standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term.Matt RosenberPopulation Density Geography.about.com. March 2, 2011. Retrieved on December 10, 2011. Biological population densities Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are: * Increased problems with locating sexual mates * Increased inbreeding Human densities Population density is the number of people per unit of area, usually transcribed as "per square kilometre" or square mile, and which may include or exclude, for example, ar ...

United States Census
The United States census (plural censuses or census) is a census that is legally mandated by the Constitution of the United States. It takes place every ten years. The first census after the American Revolution was taken in 1790 United States census, 1790 under United States Secretary of State, Secretary of State Thomas Jefferson. There have been 24 federal censuses since that time. The census includes territories of the United States. The United States Census Bureau is responsible for conducting the census. The 2020 United States census, most recent national census took place in 2020; the next census is scheduled for 2030. Since 2013, the Census Bureau began discussions on using technology to aid data collection starting with the 2020 census. In 2020, every household received an invitation to complete the census over the Internet, by phone or by paper questionnaire. For years between the decennial censuses, the Census Bureau issues estimates made using surveys and statistical mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yarmouth Interglacial
The Yarmouthian stage and the Yarmouth Interglacial were part of a now-obsolete geologic timescale of the early Quaternary of North America. Development This climatic and chronological framework was composed of four glacial and interglacial stages. It was developed between 1894 and 1909 by geomorphologists and Quaternary geologists to subdivide glacial and nonglacial deposits within the United States of America. From youngest to oldest, they were the Wisconsinian Stage (glacial), Sangamonian (interglacial), Illinoian (glacial), Yarmouthian (interglacial), Kansan (glacial), Aftonian (interglacial), and Nebraskan (glacial) stages. The Yarmouthian (Yarmouth) Interglacial was defined first on the basis of "interglacial" sediments encountered in wells dug in southeastern Iowa. Later, the Yarmouth (Yarmouthian) stage in Illinois was defined on the basis of the Yarmouth Paleosol (Soil), developed in the surface of what were thought at that time to be "Kansan" glacial tills, and burie ...

Paleosol
In Earth science, geoscience, paleosol (''palaeosol'' in Great Britain and Australia) is an ancient soil that formed in the past. The definition of the term in geology and paleontology is slightly different from its use in soil science. In geology and paleontology, a paleosol is a former soil preserved by burial underneath either sediments (alluvium or loess) or volcanic deposits (lava flows or volcanic ash), which in the case of older deposits have Lithification, lithified into Rock (geology), rock. In Quaternary geology, sedimentology, paleoclimatology, and geology in general, it is the typical and accepted practice to use the term "paleosol" to designate such "''fossil soils''" found buried within sedimentary and volcanic deposits exposed in all continents. In soil science the definition differs slightly: paleosols are soils formed long ago that have no relationship in their chemical and physical characteristics to the present-day climate or vegetation. Such soils are found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Till
image:Geschiebemergel.JPG, Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illinoian Glaciation
The Illinoian Stage is the name used by Quaternary geologists in North America to designate the Penultimate Glacial Period c.191,000 to c.130,000 years ago, during the late Middle Pleistocene (Chibanian), when sediments comprising the Illinoian Glacial Lobe were deposited. It precedes the Sangamonian Stage (corresponding to the global Last Interglacial) and follows the Pre-Illinoian Stage in North America. The Illinoian Stage is defined as the period of geologic time during which the glacial tills and outwash, which comprise the bulk of the Glasford Formation, accumulated to create the Illinoian Glacial Lobe.Willman, H.B., and J.C. Frye, 1970, ''Pleistocene Stratigraphy of Illinois.'' Bulletin no. 94, Illinois State Geological Survey, Champaign, Illinois. Definition At its type exposure in Peoria County, Illinois, the Illinoian deposits consist of three till members of the Glasford Formation. They overlay Pre-Illinoian tills of the Banner Formation, in which the Yarmouth Soil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
