Middlesboro Crater
The Middlesboro crater (or astrobleme) is a meteorite crater in Kentucky, United States. It is named after the city of Middlesborough (both spellings are used), which today occupies much of the crater. The crater is approximately 3 miles (about 5 km) wide and its age is estimated to be less than 300 million years (Permian). The impactor is estimated to have been about 100 m in diameter. History The Middlesboro crater is located in the Appalachian Mountains, between the Cumberland Mountains and Pine Mountain. It forms part of the string of geological features that made the Cumberland Gap a critical westward passage during the settlement of Kentucky and the Ohio Valley in the late 18th and early 19th centuries. Settlements The town of Middlesboro, built in the crater, was established in 1886 to exploit iron and coal deposits, although the town's founder, Alexander A. Arthur, apparently did not know of the crater's extraterrestrial origin. K. J. Englund and J. B. Roen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell County, Kentucky
Bell County is a county located in the southeast part of the U.S. state of Kentucky. As of the 2020 census, the population was 24,097. Its county seat is Pineville. The county was formed in 1867, during the Reconstruction era from parts of Knox and Harlan counties and augmented from Knox County in 1872.Census Office. ''Tenth Census of the United States'' (1880) I:62. The county is named for Joshua Fry Bell, a US Representative. It was originally called "Josh Bell", but on January 31, 1873, the Kentucky legislature shortened the name to "Bell", History Bell County is considered a "Moist" county, a classification between dry and wet in terms of alcohol sales. The County changed to moist by a vote in September 2015, that approved alcohol-by-the-drink sales in Middlesboro, Kentucky. On June 23, 2020, Middlesboro voters approved a "wet" status by 1,215 to 653 votes. In a standard dry county, all sales of alcoholic beverages are prohibited. Under ABC terminology, a limited coun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shatter Cone
Shatter cones are rare geological features that are only known to form in the bedrock beneath meteorite impact craters or underground nuclear explosions. They are evidence that the rock has been subjected to a shock with pressures in the range of . Morphology Shatter cones have a distinctively conical shape that radiates from the top (''apex'') of the cones repeating cone-on-cone in large and small scales in the same sample. Sometimes they have more of a spoon shape on the side of a larger cone. In finer-grained rocks such as limestone, they form an easily recognizable "horsetail" pattern with thin grooves (''striae''). However, the word "striae" should not be used to describe shatter cones, as that is considered misleading. Coarser grained rocks tend to yield less well developed shatter cones, which may be difficult to distinguish from other geological formations such as slickensides. Geologists have various theories of what causes shatter cones to form, including compress ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Kentucky
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

Cumberland Gap Tunnel
The Cumberland Gap Tunnel is a dual-bore, four lane vehicular tunnel that carries U.S. Route 25E under Cumberland Gap National Historical Park near the intersection of Kentucky, Tennessee, and Virginia. The tunnel consists of two separate bores which carry four lanes of traffic between Cumberland Gap, Tennessee and Middlesboro, Kentucky. It is one of only two mountain vehicular tunnels in the United States that cross a state line, the other being the East River Mountain Tunnel on Interstate 77 and U.S. Route 52 between Virginia and West Virginia. The tunnel opened to traffic in 1996 and replaced a section of highway through the Cumberland Gap that had earned the nickname "Massacre Mountain" due to its hazardous design and high rate of traffic accidents. Description The tunnels are located in the Cumberland Mountains, a subrange of the Appalachian Plateau, which is, in turn, a subrange of the Appalachian Mountains.

Distinguished Geologic Site
The ruling made by the judge or panel of judges must be based on the evidence at hand and the standard binding precedents covering the subject-matter (they must be ''followed''). Definition In law, to distinguish a case means a court decides the holding or legal reasoning of a precedent case will not apply due to materially different facts between the two cases. Two formal constraints constrain the later court: the expressed relevant factors (also known as considerations, tests, questions or determinants) in the ''ratio'' (legal reasoning) of the earlier case must be recited or their equivalent recited or the earlier case makes an exception for their application in the circumstances otherwise it envisages, and the ruling in the later case must not expressly doubt (criticise) the result reached in the precedent case.Lamond, Grant"Precedent and Analogy in Legal Reasoning: 2.1 Precedents as laying down rules:2.1.2 The practice of distinguishing".

Kentucky ( , ), officially the Commonwealth of Kentucky, is a state in the Southeastern region of the United States and one of the states of the Upper South. It borders Illinois, Indiana, and Ohio to the north; West Virginia and Virginia to the east; Tennessee to the south; and Missouri to the west. Its northern border is defined by the Ohio River. Its capital is Frankfort, and its two largest cities are Louisville and Lexington. Its population was approximately 4.5 million in 2020. Kentucky was admitted into the Union as the 15th state on June 1, 1792, splitting from Virginia in the process. It is known as the "Bluegrass State", a nickname based on Kentucky bluegrass, a species of green grass found in many of its pastures, which has supported the thoroughbred horse industry in the center of the state. Historically, it was known for excellent farming conditions for this reason and the development of large tobacco plantations akin to those in Virginia and North Carolina in ...

Coal Mining
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to th ...

Cumberland Gap Pinnacle Overlook
Cumberland ( ) is a historic county in the far North West England. It covers part of the Lake District as well as the north Pennines and Solway Firth coast. Cumberland had an administrative function from the 12th century until 1974. From 1974 until 2023, Cumberland lay within Cumbria, a larger administrative area which also covered Westmorland and parts of Yorkshire and Lancashire. In April 2023, Cumberland will be revived as an administrative entity when Cumbria County Council is abolished and replaced by two unitary authorities; one of these is to be named Cumberland and will include most of the historic county, with the exception of Penrith and the surrounding area. Cumberland is bordered by the historic counties of Northumberland to the north-east, County Durham to the east, Westmorland to the south-east, Lancashire to the south, and the Scottish counties of Dumfriesshire and Roxburghshire to the north. Early history In the Early Middle Ages, Cumbria was part of the King ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Event
An impact event is a collision between astronomical objects causing measurable effects. Impact events have physical consequences and have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect. When large objects impact terrestrial planets such as the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry. Impact craters and Impact structure, structures are dominant landforms on many of the Solar System's solid objects and present the strongest empirical evidence for their frequency and scale. Impact events appear to have played a significant role in the Formation and evolution of the Solar System, evolution of the Solar System since its formation. Major impact events have significantly shaped History of the Earth, Earth's history, and have been implicated in the giant impact theory, formation of the Earth†...
