Hickory Ridge, Arkansas
Hickory Ridge is a city in Cross County, Arkansas, United States. The population was 272 at the 2010 census. Always a small farming community with an economy based on agriculture, a post office was first established in 1875, but the community did not incorporate until 1949. History A post office in Brushy Lake Township was named Hickory Ridge on October 5, 1875. The post office was closed shortly thereafter, and the area remained very sparsely populated because the soils were too wet to grow cotton. Following the Cotton Belt railway extension through the settlement around 1882, the community saw prosperity from timber and agriculture; reestablishing the Hickory Ridge post office in 1892. The city was racially segregated along the railroad tracks (similar to the Delmar Divide), and around 1910, white residents dynamited the black section of town, expelling all black residents. The city became completely white and evolved into sundown town through unwritten rules. Geography H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
City
A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a narrower sense, a city can be defined as a permanent and Urban density, densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, Public utilities, utilities, land use, Manufacturing, production of goods, and communication. Their density facilitates interaction between people, government organisations, government organizations, and businesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution. Historically, city dwellers have been a small proportion of humanity overall, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sundown Town
Sundown towns, also known as sunset towns, gray towns, or sundowner towns, were all-white municipalities or neighborhoods in the United States. They were towns that practiced a form of racial segregation by excluding non-whites via some combination of discriminatory local laws, intimidation or violence. They were most prevalent before the 1950s. The term came into use because of signs that directed " colored people" to leave town by sundown. Sundown counties and sundown suburbs were created as well. While sundown laws became illegal following the passage of the Civil Rights Act of 1968, some commentators hold that certain 21st-century practices perpetuate a modified version of the sundown town. Some of these modern practices include racial profiling by local police and sheriff's departments, vandalism of public art, harassment by private citizens, and gentrification. Discriminatory policies and actions distinguish sundown towns from towns that have no Black residents for demo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overcup Oak
''Quercus lyrata'', the overcup oak, is an oak in the white oak group (''Quercus'' sect. ''Quercus''). The common name, overcup oak, refers to its acorns that are mostly enclosed within the acorn cup. It is native to lowland wetlands in the eastern and south-central United States, in all the coastal states from New Jersey to Texas, inland as far as Oklahoma, Missouri, and Illinois. There are historical reports of it growing in Iowa, but the species appears to have been extirpated there. It is a slow-growing tree that often takes 25 to 30 years to mature. It has an estimated lifespan of 400 years.Solomon, J. D. (1990). Quercus lyrata Walt. overcup oak. ''Silvics of North America'', ''2'', 681-685.

Loblolly Pine
''Pinus taeda'', commonly known as loblolly pine, is one of several pines native to the Southeastern United States, from East Texas to Florida, and north to southern New Jersey. The wood industry classifies the species as a southern yellow pine. U.S. Forest Service surveys found that loblolly pine is the second-most common species of tree in the United States, after red maple. For its timber, the pine species is regarded as the most commercially important tree in the Southeastern U.S. The common name loblolly is given because the pine species is found mostly in lowlands and swampy areas. Loblolly pine is the first among over 100 species of ''Pinus'' to have its complete genome sequenced. As of March 2014, it was the organism having the largest sequenced genome size. Its genome, with 22 billion base pairs, is seven times larger than that of humans. As of 2018, assembly of the axolotl genome (32Gb) displaced loblolly pine as the largest assembled genome. The loblolly pine w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post Oak
''Quercus stellata'', the post oak or iron oak, is a North American species of oak in the white oak section. It is a slow-growing oak that lives in dry areas on the edges of fields, tops of ridges, and also grows in poor soils, and is resistant to rot, fire, and drought. Interbreeding occurs among white oaks, thus many hybrid species combinations occur. It is identifiable by the rounded cross-like shape formed by the leaf lobes and hairy underside of the leaves. Taxonomy The specific epithet ''stellata'' is Latin for "star"; it is named this because the trichome hairs on the bottom of the leaves are stellate or star-shaped. Several variants of ''Q. stellata'' were named by American botanist Charles Sprague Sargent. The variety most recognised by the United States Forest Service is ''Q. stellata'' var. ''paludosa'' Sarg (delta post oak).Stransky, John J. "Quercus stellata Wangenh.--post oak.''Silvics of North America'' 2(1990): 738–743. Varieties Varieties includ ...

Loess
A loess (, ; from ) is a clastic rock, clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Ten percent of Earth's land area is covered by loesses or similar deposition (geology), deposits. A loess is a periglacial or aeolian processes, aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay with a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), often loosely cemented by calcium carbonate. Usually, they are homogeneity and heterogeneity, homogeneous and highly Porosity#Porosity in earth sciences and construction, porous and have vertical capillaries that permit the sediment to fracture and form vertical cliff, bluffs.

Mississippi Alluvial Plain (ecoregion)
The Mississippi Alluvial Plain is a Level III ecoregion designated by the Environmental Protection Agency (EPA) in seven U.S. states, though predominantly in Arkansas, Louisiana, and Mississippi. It parallels the Mississippi River from the Midwestern United States to the Gulf of Mexico. The Mississippi Alluvial Plain ecoregion has been subdivided into fifteen Level IV ecoregions. Description The Mississippi Alluvial Plain extends along the Mississippi River from the confluence of the Ohio River and Mississippi River southward to the Gulf of Mexico; temperatures and annual average precipitation increase toward the south. It is a broad, nearly level, agriculturally-dominated alluvial plain. It is veneered by Quaternary alluvium, loess, glacial outwash, and lacustrine deposits. River terraces, Swales, and levees provide limited relief, but overall, it is flatter than neighboring ecoregions in Arkansas, including the South Central Plains. Nearly flat, clayey, poorly-drained soil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arkansas Delta
The Arkansas Delta is one of the six natural regions of the state of Arkansas. Willard B. Gatewood Jr., author of ''The Arkansas Delta: Land of Paradox'', says that rich cotton lands of the Arkansas Delta make that area "The Deepest of the Deep South." The region runs along the Mississippi River from Eudora, Arkansas, Eudora north to Blytheville, Arkansas, Blytheville and as far west as Little Rock, Arkansas, Little Rock. It is part of the Mississippi embayment, itself part of the Mississippi Alluvial Plain, Mississippi River Alluvial Plain. The flat plain is bisected by Crowley's Ridge, a narrow band of rolling hills rising above the flat delta plains. Several towns and cities have been developed along Crowley's Ridge, including Jonesboro, Arkansas, Jonesboro. The region's lower western border follows the Arkansas River just outside Little Rock, Arkansas, Little Rock down through Pine Bluff, Arkansas, Pine Bluff. There the border shifts to Bayou Bartholomew, stretching south t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mississippi River
The Mississippi River is the main stem, primary river of the largest drainage basin in the United States. It is the second-longest river in the United States, behind only the Missouri River, Missouri. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's Drainage basin, watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky Mountains, Rocky and Appalachian Mountains, Appalachian mountains. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the world's List of rivers by discharge, tenth-largest river by discharge flow, and the largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mississippi Alluvial Plain
The Mississippi River Alluvial Plain is an alluvial plain created by the Mississippi River on which lie parts of seven U.S. states, from southern Louisiana to southern Illinois (Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, Louisiana). The plain is divided into (a) the Mississippi River Delta in the southern half of Louisiana and (b) the upper Mississippi Embayment running from central Louisiana to Illinois. The term "Mississippi embayment" is sometimes used more narrowly to refer to its section on the western side of the river, running through eastern Arkansas, southeastern Missouri, westernmost Tennessee (east side of the River), westernmost Kentucky (east side of the River) and southernmost Illinois, and excluding northwest Mississippi where the alluvial plain is known as the Mississippi Delta. Most of the alluvium in the lower Mississippi valley is thought to be sourced from the west.Steponaitis, Vincas P., et al. “Large-Scale Patterns in the Chemical ...

Mississippi Embayment
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. Geography The embayment is a topographically low-lying basin that is filled with Cretaceous to recent sediments. The northern end of the embayment appears as a ...
