Atoka County
Atoka County is a county located in the U.S. state of Oklahoma. As of the 2010 census, the population was 14,007. Its county seat is Atoka. The county was formed before statehood from Choctaw Lands, and its name honors a Choctaw Chief named Atoka. History The area forming Atoka County was part of the Choctaw Nation after the tribe was forced to relocate in the early 1830s to Indian Territory from its home in the Southeastern United States. Unlike the State of Oklahoma, whose county boundaries follow the precise north–south, east–west grid established with the state's township and range system, the Choctaw Nation established its internal divisions using easily recognizable landmarks, such as mountains and rivers, as borders. The territory of present-day Atoka County fell within the Pushmataha District, one of the three administrative super-regions comprising the Choctaw Nation. Within that district, it was in parts of Atoka, Blue, and Jack's Fork counties. The Choctaw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
County (United States)
In the United States, a county is an administrative or political subdivision of a state that consists of a geographic region with specific boundaries and usually some level of governmental authority. The term "county" is used in 48 states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs, respectively. The specific governmental powers of counties vary widely between the states, with many providing some level of services to civil townships, municipalities, and unincorporated areas. Certain municipalities are in multiple counties; New York City is uniquely partitioned into five counties, referred to at the city government level as boroughs. Some municipalities have consolidated with their county government to form consolidated city-counties, or have been legally separated from counties altogether to form independent cities. Conversely, those counties in Connecticut, Rhode Island, eight of Massachusetts's 14 counties, and Alaska ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Choctaw Country
Choctaw Country is the Oklahoma Department of Tourism and Recreation's official tourism designation for Southeastern Oklahoma. The name was previously Kiamichi Country until changed in honor of the Choctaw Nation headquartered there. The current definition of Choctaw Country includes ten counties, being Coal, Atoka, Bryan, Choctaw, McCurtain, Pushmataha, Le Flore, Latimer, Haskell, and Pittsburg counties. The department created the term as one of six designated travel regions within the state. However, other definitions of Southeastern Oklahoma may include additional counties. The original name of Kiamichi was applied by French explorers who came to the area in the early 18th century. They discovered, among other things, a very large, noisy woodpecker that they called ''Kiamichi'', their word for "raucous bird." This name was also applied to the Kiamichi Mountains (Choctaw: ''Nʋnih Chaha Kiamitia''), a subset of the Ouachita Mountains. Due to an influx of southerners se ...

US 75
U.S. Route 75 is a major north–south U.S. Highway that extends in the central United States. The highway's northern terminus is in Noyes, Minnesota, at the Canadian border, where it once continued as Manitoba Highway 75 on the other side of the now-closed border crossing. Its southern terminus is at Interstate 30 (I-30) and I-45 in Dallas, where it is known as North Central Expressway. US 75 was previously a cross-country route, from Canada to the Gulf of Mexico at Galveston, Texas, but the entire segment south of Dallas has been decommissioned in favor of I-45, a cutoff section of town-to-town surface road having become Texas State Highway 75. Route description Texas The first freeway in Texas was a several-mile stretch of US 75 (now I-45)—The Gulf Freeway—opened to Houston traffic on October 1, 1948. The stretch of US 75 between I-30 and the Oklahoma state line has exits numbered consecutively from 1 to 75 (with occasional A and B designations), excl ...

Global Boundary Stratotype Section And Point
A Global Boundary Stratotype Section and Point (GSSP) is an internationally agreed upon reference point on a stratigraphic section which defines the lower boundary of a stage on the geologic time scale. The effort to define GSSPs is conducted by the International Commission on Stratigraphy, a part of the International Union of Geological Sciences. Most, but not all, GSSPs are based on paleontological changes. Hence GSSPs are usually described in terms of transitions between different faunal stages, though far more faunal stages have been described than GSSPs. The GSSP definition effort commenced in 1977. As of 2022, 77 of the 101 stages that need a GSSP have a ratified GSSP. Rules A geologic section has to fulfill a set of criteria to be adapted as a GSSP by the ICS. The following list summarizes the criteria: * A GSSP has to define the lower boundary of a geologic stage. * The lower boundary has to be defined using a primary marker (usually first appearance datum of a fo ...

Ordovician
The Ordovician ( ) is a geologic period and System (geology), system, the second of six periods of the Paleozoic Era (geology), Era. The Ordovician spans 41.6 million years from the end of the Cambrian Period million years ago (Mya) to the start of the Silurian Period Mya. The Ordovician, named after the Celtic Britons, Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same Rock (geology), rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed Stratum, strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official period of the Paleozoic Era by the International Union of Geological Sciences, Intern ...

Katian
The Katian is the second stage of the Upper Ordovician. It is preceded by the Sandbian and succeeded by the Hirnantian Stage. The Katian began million years ago and lasted for about 7.8 million years until the beginning of the Hirnantian million years ago. During the Katian the climate cooled which started the Late Ordovician glaciation. Naming The name Katian is derived from Katy Lake (Atoka County, Oklahoma, United States). GSSP The GSSP of the Katian Stage is the Black Knob Ridge Section in southeastern Oklahoma (United States). It is an outcrop of the Womble Shale and the Bigfork Chert, the latter containing the lower boundary of the Katian. The lower boundary is defined as the first appearance datum of the graptolite Graptolites are a group of colonial animals, members of the subclass Graptolithina within the class Pterobranchia.

Boggy Depot State Park
A bog or bogland is a wetland that accumulates peat as a deposit of dead plant materials often mosses, typically sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens. A baygall is another type of bog found in the forest of the Gulf Coast states in the United States.Watson, Geraldine Ellis (2000) ''Big Thicket Plant Ecology: An Introduction'', Third Edition (Temple Big Thicket Series #5). University of North Texas Press. Denton, Texas. 152 pp. Texas Parks and Wildlife. Ecological Mapping systems of Texas: West Gulf Coastal Plain Seepage Swamp and Baygall'. Retrieved 7 July 2020 They are often covered in heath or heather shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink. Bogs occur where the water at the ground surface is acidic and low in nutrients. In contrast to fens, they derive most o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ouachita Mountains
The Ouachita Mountains (), simply referred to as the Ouachitas, are a mountain range in western Arkansas and southeastern Oklahoma. They are formed by a thick succession of highly deformed Paleozoic strata constituting the Ouachita Fold and Thrust Belt, one of the important orogenic belts of North America. The Ouachitas continue in the subsurface to the northeast, where they make a poorly understood connection with the Appalachians and to the southwest, where they join with the Marathon uplift area of West Texas. Together with the Ozark Plateaus, the Ouachitas form the U.S. Interior Highlands. The highest natural point is Mount Magazine at . The Ouachita Mountains is a Level III ecoregion designated by the Environmental Protection Agency (EPA). The region has been subdivided into six Level IV ecoregions. Etymology Louis R. Harlan claimed that "Ouachita" is composed of the Choctaw words ''ouac'' for "buffalo" and ''chito'' for "large", together meaning "country of large buffa ...
