Cumberland Mountains
The Cumberland Mountains are a mountain range in the southeastern section of the Appalachian Mountains. They are located in western Virginia, southwestern West Virginia, the eastern edges of Kentucky, and eastern middle Tennessee, including the Crab Orchard Mountains. Their highest peak, with an elevation of above mean sea level, is High Knob, which is located near Norton, Virginia. According to the USGS, the Cumberland Mountain range is long and wide, bounded by the Russell Fork on the northeast, the Pound River and Powell River on the southeast, Cove Creek on the southwest, and Tackett Creek, the Cumberland River, Poor Fork Cumberland River, and Elkhorn Creek on the northwest. The crest of the range forms the Kentucky and Virginia boundary from the Tennessee border to the Russell Fork River. Variant names of the Cumberland Mountains include Cumberland Mountain, Cumberland Range, Ouasioto Mountains, Ouasiota Mountains, Laurel Mountain, and Pine Mountain. They are named ...

Cross Mountain (Tennessee)
Cross Mountain is a mountain in the Cumberland Mountains in the U.S. state of Tennessee. At an elevation of , it is the highest mountain in Tennessee that is not part of the Blue Ridge Mountains. It contains rich deposits of coal, and in 1911 was the site of one of the deadliest mining disasters in state history. Geography and geology Cross Mountain is located in the southern Cumberland Mountains, part of the larger Appalachian Plateau province of the Appalachian Mountains. It consists of a series of ridges, running roughly northeast-southwest. Its summit, known as The Flag Pole, reaches an elevation of , is located on the border between Anderson and Campbell Counties, and contains multiple transmission antennas. Coal Creek, a tributary of the Clinch River, flows along the southeastern base of the Mountain. Slatestone Creek, flows westward down the slopes of Cross Mountain into Coal Creek.

Pineville, Kentucky
Pineville () is a home rule-class city in Bell County, Kentucky, United States. It is the seat of its county. The population was 1,732 as of the 2010 census. It is located on a small strip of land between the Cumberland River and Pine Mountain. History Pineville is one of the oldest settlements in Kentucky, located at the crossing of the Cumberland River by the Wilderness Road. It was established as Cumberland Ford in 1781 and formed part of Governor Isaac Shelby's land tracts. When Bell County was formed in 1867, Cumberland Ford was formally laid off; local landowner J.J. Gibson's 1869 land grant permitted it to be selected as the county seat, but the courthouse was not completed until 1871.Rennick, Robert. ''Kentucky Place Names''p. 235 University Press of Kentucky (Lexington), 1987. Accessed 1 August 2013. Accessed 25 April 2010. The settlement was renamed "Pineville" in 1870 and formally incorporated in 1873. One of the earliest branches of the Sojourner Truth Woman's C ...

Jellico, Tennessee
Jellico is a city in Campbell County, Tennessee, United States, on the state border with Kentucky, by road north of Knoxville. The population was 2,355 at the 2010 census. History The name "Jellico" is a local alteration of "angelica", the name of an herb that grows in abundance in the surrounding mountains. The name was first applied to the mountains to the west and to the mountains' main drainage, Jellico Creek, which passes west of the city of Jellico and empties into the Cumberland River near Williamsburg, Kentucky. In the early 1880s, a high quality bituminous coal was discovered in the Jellico Mountains, and with the completion of railroad tracks to the area in 1883, coal mines quickly sprang up throughout the area. The city of Jellico was initially founded as "Smithburg" in 1878 but changed its name to "Jellico" in 1883 to capitalize on the growing popularity of Jellico coal. The city was incorporated on March 7, 1883.James Hayden Siler,The History of Jellico" Unpublis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strike And Dip
Strike and dip is a measurement convention used to describe the orientation, or attitude, of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination measured downward from horizontal. They are used together to measure and document a structure's characteristics for study or for use on a geologic map. A feature's orientation can also be represented by dip and dip direction, using the azimuth of the dip rather than the strike value. Linear features are similarly measured with trend and plunge, where "trend" is analogous to dip direction and "plunge" is the dip angle. Strike and dip are measured using a compass and a clinometer. A compass is used to measure the feature's strike by holding the compass horizontally against the feature. A clinometer measures the features dip by recording the inclination perpendicular to the strike. These can be done separately, or together using a tool such ...

Dip Slope
A dip slope is a topographic (geomorphic) surface which slopes in the same direction, and often by the same amount, as the true dip or apparent dip of the underlying strata.Jackson, JA, J Mehl and K Neuendorf (2005) ''Glossary of Geology.'' American Geological Institute, Alexandria, Virginia. 800 pp. Allaby, M (2008) ''A Dictionary of Earth Science.'' Oxford University Press, New York, New York. 654 pp. A dip slope consists of the upper surface of a resistant layer of rock, often called ''caprock'', that is commonly only slightly lowered and reduced in steepness by erosion. Dip slopes form the backslopes of cuestas, homoclinal ridges, hogbacks, and flatirons. The frontslopes of such ridges consist of either an escarpment, a steep slope, or perhaps even a line of cliffs. Generally, cuestas and homoclinal ridges are asymmetrical in that their dip slopes are less steep than their escarpments. In the case of hogbacks and flatirons, the dip of the rocks is so steep that their dip s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thrust Fault
A thrust fault is a break in the Earth's crust, across which older rocks are pushed above younger rocks. Thrust geometry and nomenclature Reverse faults A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. If the angle of the fault plane is lower (often less than 15 degrees from the horizontal) and the displacement of the overlying block is large (often in the kilometer range) the fault is called an ''overthrust'' or ''overthrust fault''. Erosion can remove part of the overlying block, creating a ''fenster'' (or '' window'') – when the underlying block is exposed only in a relatively small area. When erosion removes most of the overlying block, leaving island-like remnants resting on the lower block, the remnants are called ''klippen'' (singular '' klippe''). Blind thrust faults If the fault plane terminates before it reaches the Earth's surface, it is referred to as a ''blind thrust'' fault. Because of the lack of surface evidence, blind ...

Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the ICS geologic timescale, the younger of two subperiods (or upper of two subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronologic units, the rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. The division between Pennsylvanian and Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian. In parts of Europe, the Mississippian and Pennsylvanian are one more-or-less continuous sequence of lowland continental deposits and are grouped t ...

Breaks Interstate Park
Breaks Interstate Park is a bi-state state park located partly in southeastern Kentucky and mostly in southwestern Virginia, in the Jefferson National Forest, at the northeastern terminus of Pine Mountain. Rather than their respective state park systems, it is instead administered by an interstate compact between the states of Virginia and Kentucky. It is one of several interstate parks in the United States, but only one of two operated jointly under a compact rather than as two separate state park units. The Virginia Department of Conservation and Recreation and the Kentucky Department of Parks are still major partner organizations, however. The Breaks is also referred as the "Grand Canyon of the South", through which the Russell Fork river and Clinchfield Railroad (now the CSX Transportation Kingsport Subdivision) run. It is accessed via highway 80 ( Virginia 80 and Kentucky 80), between Haysi, Virginia, and Elkhorn City, Kentucky, and passes through the community of B ...

Appalachian Plateau
The Appalachian Plateau is a series of rugged dissected plateaus located on the western side of the Appalachian Mountains. The Appalachian Mountains are a mountain range that run down the Eastern United States. The Appalachian Plateau is the northwestern part of the Appalachian Mountains, stretching from New York to Alabama. The plateau is a second level United States physiographic region, covering parts of the states of New York, Pennsylvania, Ohio, Maryland, West Virginia, Virginia, Kentucky, Tennessee, Alabama, and Georgia. Geography and physical features The formation of the plateau began during the Paleozoic Era. Regional uplift during this time caused the area to rise altogether without changing the topography of the land. The eastern side of the plateau appears as a mountain range. This false appearance is due to a very steep slope on the eastern side known as the Allegheny Front. The eastern edge is the highest part of the Appalachian Plateau. In Pennsylvania, the ...

Physiographic Regions Of The World
Physiographic regions of the world are a means of defining Earth's landforms into distinct regions, based upon the classic three-tiered approach by Nevin M. Fenneman in 1916, that separates landforms into physiographic divisions, physiographic provinces, and physiographic sections. Originally used in North America, the model became the basis for similar classifications of other continents, and was still considered valid . Physiography During the early 1900s, the study of regional-scale geomorphology was termed "physiography". Physiography later was considered to be a contraction of "''physi''cal" and "ge''ography''", and therefore synonymous with physical geography, and the concept became embroiled in controversy surrounding the appropriate concerns of that discipline. Some geomorphologists held to a geological basis for physiography and emphasized a concept of physiographic regions while a conflicting trend among geographers was to equate physiography with "pure morphology," se ...
