Natural Tunnel State Park
Natural Tunnel State Park is a Virginia state park, centered on the Natural Tunnel, a massive naturally formed cave that is so large it is used as a railroad tunnel. It is located in the Appalachian Mountains near Duffield in Scott County, Virginia. The Natural Tunnel, which is up to wide and high, began to form more than a million years ago when groundwater bearing carbonic acid percolated through crevices and slowly dissolved limestone and dolomite bedrock. A small river, which is now called Stock Creek, was diverted underground and it continued to erode the tunnel over many millennia. The walls of the tunnel show evidence of prehistoric life. Many fossils have been found in the creek bed and in the tunnel walls. Geology The tunnel passes through Purchase Ridge, which is made of the Ordovician Chepultepec Limestone and is near the axis of the Purchase Ridge syncline. It lies between the Clinchport Thrust Fault and the Hunter Valley Thrust Fault, on the Hunter Valley Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scott County, Virginia
Scott County is a county located in the southwestern part of the U.S. state of Virginia. As of the 2020 census, the population was 21,576. Its county seat is Gate City. Scott County was formed by an act of the General Assembly on November 24, 1814, from parts of Washington, Lee, and Russell Counties and was named for Virginia born General Winfield Scott.

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Daniel Boone
Daniel Boone (September 26, 1820) was an American pioneer and frontiersman whose exploits made him one of the first folk heroes of the United States. He became famous for his exploration and settlement of Kentucky, which was then beyond the western borders of the Thirteen Colonies. In 1775, Boone blazed the Wilderness Road through the Cumberland Gap and into Kentucky, in the face of resistance from American Indians, for whom Kentucky was a traditional hunting ground. He founded Boonesborough, one of the first English-speaking settlements west of the Appalachian Mountains. By the end of the 18th century, more than 200,000 people had entered Kentucky by following the route marked by Boone. Boone served as a militia officer during the Revolutionary War (1775–1783), which was fought in Kentucky primarily between American settlers and British-allied Indians. Boone was taken in by Shawnees in 1778 and adopted into the tribe, but he resigned and continued to help protect the Ken ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shawnee
The Shawnee are an Algonquian-speaking indigenous people of the Northeastern Woodlands. In the 17th century they lived in Pennsylvania, and in the 18th century they were in Pennsylvania, Ohio, Indiana and Illinois, with some bands in Kentucky and Alabama. By the 19th century, they were forcibly removed to Missouri, Kansas, Texas, and ultimately Indian Territory, which became Oklahoma under the 1830 Indian Removal Act. Today, Shawnee people are enrolled in three federally recognized tribes, all headquartered in Oklahoma: the Absentee-Shawnee Tribe of Indians, Eastern Shawnee Tribe of Oklahoma, and Shawnee Tribe. Etymology Shawnee has also been written as Shaawanwaki, Ša·wano·ki, Shaawanowi lenaweeki, and Shawano. Algonquian languages have words similar to the archaic ''shawano'' (now: ''shaawanwa'') meaning "south". However, the stem ''šawa-'' does not mean "south" in Shawnee, but "moderate, warm (of weather)": See Charles F. Voegelin, "šawa (plus -ni, -te) MODERATE, WARM ...

Cherokee
The Cherokee (; chr, ᎠᏂᏴᏫᏯᎢ, translit=Aniyvwiyaʔi or Anigiduwagi, or chr, ᏣᎳᎩ, links=no, translit=Tsalagi) are one of the indigenous peoples of the Southeastern Woodlands of the United States. Prior to the 18th century, they were concentrated in their homelands, in towns along river valleys of what is now southwestern North Carolina, southeastern Tennessee, edges of western South Carolina, northern Georgia, and northeastern Alabama. The Cherokee language is part of the Iroquoian language group. In the 19th century, James Mooney, an early American ethnographer, recorded one oral tradition that told of the tribe having migrated south in ancient times from the Great Lakes region, where other Iroquoian peoples have been based. However, anthropologist Thomas R. Whyte, writing in 2007, dated the split among the peoples as occurring earlier. He believes that the origin of the proto-Iroquoian language was likely the Appalachian region, and the split betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...
