Carter County, Oklahoma
Carter County is a county in the U.S. state of Oklahoma. As of the 2010 census, the population was 47,557. Its county seat is Ardmore. The county was named for Captain Ben W. Carter, a Cherokee who lived among the Chickasaw.O'Dell, Larry"Carter County,"''Encyclopedia of Oklahoma History and Culture'', 2009. Accessed March 28, 2015. Carter County is part of the Ardmore Micropolitan Statistical Area. It is also a part of the Texoma region. History Prior to statehood, the present Carter County, Oklahoma, was part of Pickens County in the Chickasaw Nation of the Indian Territory. After the Civil War, the government of the United States forced the Chickasaw government to allow railroads built across its territory. The Gulf, Colorado and Santa Fe Railway (controlled by the Atchison, Topeka and Santa Fe Railway, AT&SF) built a line north from Texas to Purcell. In 1901-1903 the Arkansas and Choctaw Railway (acquired by the St. Louis and San Francisco Railway in 1907) built a lin ... [...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] |
Cross Timbers
The term Cross Timbers, also known as Ecoregion 29, Central Oklahoma/Texas Plains, is used to describe a strip of land in the United States that runs from southeastern Kansas across Central Oklahoma to Central Texas. Made up of a mix of prairie, savanna, and woodland, it forms part of the boundary between the more heavily forested eastern country and the almost treeless Great Plains, and also marks the western habitat limit of many mammals and insects. No major metropolitan areas lie wholly within the Cross Timbers, although roughly the western half of the Dallas-Fort Worth Metroplex does, including the cities of Fort Worth, Texas, Fort Worth, Denton, Texas, Denton, Arlington, Texas, Arlington, and Weatherford, Texas, Weatherford. The western suburbs of the Tulsa metropolitan area and the northeastern suburbs of the Oklahoma City metropolitan area also lie within this area. The main highways that cross the region are Interstate 35, I-35 and Interstate 35W (Texas), I-35W going ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
US 77
U.S. Route 77 (US 77) is a major north–south United States Numbered Highway which extends for in the central United States. As of 2005, Its southern terminus is in Brownsville, Texas, at Veteran's International Bridge on the Mexican border, where it connects with both Mexican Federal Highway 101 and Mexican Federal Highway 180, and the highway's northern terminus is in Sioux City, Iowa, at an interchange with Interstate 29 (I-29). It is unsigned in and around Dallas, Texas. Its historic segment through South Dakota and Minnesota was decommissioned with the advent of I-29 but otherwise the route has been spared the decommissioning that has shortened other US Highways. The route has major freeway sections in Oklahoma City including the Broadway Extension connecting suburban Edmond to downtown Oklahoma City. Route description Texas The section between the Oklahoma–Texas state line and Waco is mostly co-located with I-35 and the I-35E branch through Dallas, and where it is co ...

US 70
U.S. Route 70 or U.S. Highway 70 (US 70) is an east–west United States highway that runs for from eastern North Carolina to east-central Arizona. It is a major east–west highway of the Southeastern, Southern and Southwestern United States. Established as one of the original highways of 1926, it originally ran only to Holbrook, Arizona, then was extended in 1934 as a coast to coast route, with the current Eastern terminus near the Atlantic Ocean in Atlantic, North Carolina, and the former Western terminus near the Pacific Ocean in Los Angeles, California. The current Western terminus was then truncated to US 60 / SR 77 in Globe, Arizona. Before the completion of the Interstate system, U.S. Highway 70 was sometimes referred to as the "Broadway of America", due to its status as one of the main east–west thoroughfares in the nation. It was also promoted as the "Treasure Trail" by the U.S. Highway 70 Association as of 1951. In the early years, US 70 had a different route ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wichita Orogeny
The Wichita Mountains are located in the southwestern portion of the U.S. state of Oklahoma. It is the principal relief system in the Southern Oklahoma Aulacogen, being the result of a failed continental rift. The mountains are a northwest-southeast trending series of rocky promontories, many capped by 500 million-year old granite. These were exposed and rounded by weathering during the Pennsylvanian & Permian Periods. The eastern end of the mountains offers of topographic relief in a region otherwise dominated by gently rolling grasslands. The mountains are home to numerous working ranches and quarry operations, the state reformatory, recreational homes and campsites, and scenic parklands. Fort Sill, home of the U.S. Army Field Artillery School, occupies a large portion of the southeastern end of the mountains. Recreation The Wichita Mountains National Wildlife Refuge, a favorite for hikers and rock climbers in the region, is located adjacent to Cache, Medicine Park, Indiah ...

Anticline
In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core, whereas a syncline is the inverse of an anticline. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge. Anticlines can be recognized and differentiated from antiforms by a sequence of rock layers that become progressively older toward the center of the fold. Therefore, if age relationships between various rock strata are unknown, the term antiform should be used. The progressing age of the rock strata towards the core and uplifted center, are the trademark indications for evidence of anticlines on a geologic map. These formations occur because anticlinal ridges typically develop above thrust faults during crustal deformations. The uplifted core of the fold causes compression of strata that preferentially erodes to a deeper st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
