Blue Ridge Mountains
The Blue Ridge Mountains are a physiographic province of the larger Appalachian Mountains range. The mountain range is located in the eastern United States, extends 550 miles southwest from southern Pennsylvania through Maryland, West Virginia, North Carolina, South Carolina and Georgia; this province consists of northern and southern physiographic regions, which divide near the Roanoke River gap. To the west of the Blue Ridge, between it and the bulk of the Appalachians, lies the Great Appalachian Valley, bordered on the west by the Ridge and Valley province of the Appalachian range; the Blue Ridge Mountains are noted for having a bluish color. Trees put the "blue" in Blue Ridge, from the isoprene released into the atmosphere, thereby contributing to the characteristic haze on the mountains and their distinctive color. Within the Blue Ridge province are two major national parks – the Shenandoah National Park in the northern section, the Great Smoky Mountains National Park in the southern section – and eight national forests including George Washington and Jefferson National Forests, Cherokee National Forest, Pisgah National Forest, Nantahala National Forest and Chattahoochee National Forest.
The Blue Ridge contains the Blue Ridge Parkway, a 469-mile long scenic highway that connects the two parks and is located along the ridge crest-lines with the Appalachian Trail. Although the term "Blue Ridge" is sometimes applied to the eastern edge or front range of the Appalachian Mountains, the geological definition of the Blue Ridge province extends westward to the Ridge and Valley area, encompassing the Great Smoky Mountains, the Great Balsams, the Roans, the Blacks, the Brushy Mountains and other mountain ranges; the Blue Ridge extends as far north into Pennsylvania as South Mountain. While South Mountain dwindles to mere hills between Gettysburg and Harrisburg, the band of ancient rocks that form the core of the Blue Ridge continues northeast through the New Jersey and Hudson River highlands reaching The Berkshires of Massachusetts and the Green Mountains of Vermont; the Blue Ridge contains the highest mountains in eastern North America south of Baffin Island. About 125 peaks exceed 5,000 feet in elevation.
The highest peak in the Blue Ridge is Mt. Mitchell in North Carolina at 6,684 feet. There are 39 peaks in North Tennessee higher than 6,000 feet. Southern Sixers is a term used by peak baggers for this group of mountains; the Blue Ridge Parkway runs 469 miles along crests of the Southern Appalachians and links two national parks: Shenandoah and Great Smoky Mountains. In many places along the parkway, there are metamorphic rocks with folded bands of light-and dark-colored minerals, which sometimes look like the folds and swirls in a marble cake. Most of the rocks that form the Blue Ridge Mountains are ancient granitic charnockites, metamorphosed volcanic formations, sedimentary limestone. Recent studies completed by Richard Tollo, a professor and geologist at George Washington University, provide greater insight into the petrologic and geochronologic history of the Blue Ridge basement suites. Modern studies have found that the basement geology of the Blue Ridge is made of compositionally unique gneisses and granitoids, including orthopyroxene-bearing charockites.
Analysis of zircon minerals in the granite completed by John Aleinikoff at the U. S. Geological Survey has provided more detailed emplacement ages. Many of the features found in the Blue Ridge and documented by Tollo and others have confirmed that the rocks exhibit many similar features in other North American Grenville-age terranes; the lack of a calc-alkaline affinity and zircon ages less than 1,200 Ma suggest that the Blue Ridge is distinct from the Adirondacks, Green Mountains, the New York-New Jersey Highlands. The petrologic and geochronologic data suggest that the Blue Ridge basement is a composite orogenic crust, emplaced during several episodes from a crustal magma source. Field relationships further illustrate that rocks emplaced prior to 1,078–1,064 Ma preserve deformational features; those emplaced post-1,064 Ma have a massive texture and missed the main episode of Mesoproterozoic compression. The Blue Ridge Mountains began forming during the Silurian Period over 400 million years ago.
320 Mya, North America, Europe collided, pushing up the Blue Ridge. At the time of their emergence, the Blue Ridge were among the highest mountains in the world and reached heights comparable to the much younger Alps. Today, due to weathering and erosion over hundreds of millions of years, the highest peak in the range, Mount Mitchell in North Carolina, is only 6,684 feet high – still the highest peak east of the Rockies; the English who settled colonial Virginia in the early 17th century recorded that the native Powhatan name for the Blue Ridge was Quirank. At the foot of the Blue Ridge, various tribes including the Siouan Manahoacs, the Iroquois, the Shawnee hunted and fished. A German physician-explorer, John Lederer, first reached the crest of the Blue Ridge in 1669 and again the following year. At the Treaty of Albany negotiated by Lieutenant Governor Alexander Spotswood, of Virginia with the Iroquois between 1718 and 1722, the Iroquois ceded lands they had conquered south of the Potomac River and east of the Blue Ridge to the Virginia Colony.
This treaty made the Blue Ridge the new demarcation point between the areas and tribes subject to the Six Nati
In Norse mythology, Valhalla is a majestic, enormous hall located in Asgard, ruled over by the god Odin. Chosen by Odin, half of those who die in combat travel to Valhalla upon death, led by valkyries, while the other half go to the goddess Freyja's field Fólkvangr. In Valhalla, the dead join the masses of those who have died in combat known as Einherjar and various legendary Germanic heroes and kings, as they prepare to aid Odin during the events of Ragnarök. Before the hall stands the golden tree Glasir, the hall's ceiling is thatched with golden shields. Various creatures live around Valhalla, such as the stag Eikþyrnir and the goat Heiðrún, both described as standing atop Valhalla and consuming the foliage of the tree Læraðr. Valhalla is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, the Prose Edda, Heimskringla and in stanzas of an anonymous 10th century poem commemorating the death of Eric Bloodaxe known as Eiríksmál as compiled in Fagrskinna.
Valhalla has inspired various works of art, publication titles, elements of popular culture, has become a term synonymous with a martial hall of the chosen dead. The Modern English noun Valhalla derives from Old Norse Valhöll, a compound noun composed of two elements: the masculine noun valr'the slain' and the feminine noun höll'hall'. Valr has cognates in other Germanic languages such as Old English wæl'the slain, carnage', Old Saxon wal-dād'murder', Old High German'battlefield, blood bath'. All of these forms descend from the Proto-Germanic masculine noun *walaz. Among related Old Norse concepts, valr appears as the first element of the nouns valkyrja'chooser of the slain, valkyrie' and Valfreyja, one of the goddess Freyja's several names; the second element, höll, is a common Old Norse noun. It has the same meaning. Both developed from Proto-Germanic *xallō or *hallō, meaning'covered place, hall', itself from the Proto-Indo-European root *kol-; as philologists such as Calvert Watkins have noted, the same Indo-European root produced Old Norse hel, a proper noun employed for both the name of another afterlife location and a supernatural female entity who oversees it, as well as the modern English noun hell.
In Swedish folklore, some mountains that were traditionally regarded as abodes of the dead were called Valhall. Valhalla is referenced at length in the Poetic Edda poem Grímnismál, Helgakviða Hundingsbana II, while Valhalla receives lesser direct references in stanza 33 of the Völuspá, where the god Baldr's death is referred to as the "woe of Valhalla", in stanzas 1 to 3 of Hyndluljóð, where the goddess Freyja states her intention of riding to Valhalla with Hyndla, in an effort to help Óttar, as well as in stanzas 6 through 7, where Valhalla is mentioned again during a dispute between the two. In stanzas 8 to 10 of Grímnismál, the god Odin states that Valhalla is located in the realm of Glaðsheimr. Odin describes Valhalla as shining and golden, that it "rises peacefully" when seen from afar. From Valhalla, every day Odin chooses from those. Valhalla has spear-shafts for rafters, a roof thatched with shields, coats of mail are strewn over its benches, a wolf hangs in front of its west doors, an eagle hovers above it.
From stanzas 22 to 24, more details are given by Odin about Valhalla: the holy doors of the ancient gate Valgrind stand before Valhalla, Valhalla has five hundred and forty doors that eight hundred men can exit from at once. Within Valhalla exists Thor's hall Bilskirnir, within it exist five hundred and forty rooms, of all the halls within Valhalla, Odin states that he thinks his son's may be greatest. In stanzas 25 through 26, Odin states that the goat Heiðrún and the hart Eikþyrnir stand on top of Valhalla and graze on the branches of the tree Læraðr. Heiðrún produces vats of mead that liquor cannot be compared to, from Eikþyrnir's antlers drip liquid into the spring Hvergelmir from which flows forth all waters. In stanza 38 of the poem Helgakviða Hundingsbana II, the hero Helgi Hundingsbane dies and goes to Valhalla. In stanza 38, Helgi's glory there is described: So was Helgi beside the chieftains like the bright-growing ash beside the thorn-bush and the young stag, drenched in dew, who surpasses all other animals and whose horns glow against the sky itself.
Prose follows after this stanza, stating that a burial-mound was made for Helgi, that when Helgi arrived in Valhalla, he was asked by Odin to manage things with him. In stanza 39, now in Valhalla, has his former enemy Hunding—also in Valhalla—do menial tasks. In stanzas 40 to 42, Helgi has returned to Midgard from Valhalla with a host of men. An unnamed maid of Sigrún, Helgi's valkyrie wife, sees Helgi and his large host of men riding into the mound; the maid asks if she is experiencing a delusion, if Ragnarök has begun, or if Helgi and his men have been allowed to return. In the stanzas that follow, Helgi responds that none of these things have occurred, so Sigrún's maid goes home to Sigrún; the maid tells Sigrún that the burial mound has opened up, that Sigrún should go to Helgi there, as Helgi has asked her to come and tend his wounds, which have opened up and are bleeding. Sigrún goes into the mound, finds that Helgi is drenched in g
The Keil Farm is a property listed on the National Register of Historic Places, located near South Carolina Highway 11 in the vicinity of Walhalla, South Carolina, in Oconee County. The property includes six contributing outbuildings; the farm, built by John Henry Keil, Sr. is seen as an important symbol of the role German immigrant families played in the development of the area. Structures contributing to the historic nature of the property include a barn, a corn crib, a smoke house, tenant house, a chicken house and an outhouse. Most of the outbuildings were constructed before 1860; the 1 1⁄2-story L-shaped frame farmhouse had two rooms. Through a number of additions since it was first constructed c. 1850, the house has seven rooms, two halls, a kitchen, two porches, an inset porch, three stoops and three baths. The house sits on a fieldstone foundation, constructed without the use of mortar; the exterior walls are made of heart pine overlapping boards. The gabled tin roof is a c. 1900 replacement for the original wooden-shingle roof.
Of the 6 exterior doors, 5 are original. The dining room features heart pine tongue-and-groove boards on the wall and ceiling with wide floor boards; the living room has beaded boards on the walls and ceiling and a fireplace with a mantel. The kitchen has the original wide floor and ceiling boards. Electricity and plumbing were not added to the home until 1948; the finished loft features walls and ceilings made from unpainted heart pine tongue-and-groove boards and extensive storage space. The house remained in the family until 1994. After a period of neglect, the house was re-purchased by members of the family in 1996, who undertook a partial restoration of the house
National Register of Historic Places
The National Register of Historic Places is the United States federal government's official list of districts, buildings and objects deemed worthy of preservation for their historical significance. A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred preserving the property; the passage of the National Historic Preservation Act in 1966 established the National Register and the process for adding properties to it. Of the more than one million properties on the National Register, 80,000 are listed individually; the remainder are contributing resources within historic districts. For most of its history the National Register has been administered by the National Park Service, an agency within the United States Department of the Interior, its goals are to help property owners and interest groups, such as the National Trust for Historic Preservation, coordinate and protect historic sites in the United States.
While National Register listings are symbolic, their recognition of significance provides some financial incentive to owners of listed properties. Protection of the property is not guaranteed. During the nomination process, the property is evaluated in terms of the four criteria for inclusion on the National Register of Historic Places; the application of those criteria has been the subject of criticism by academics of history and preservation, as well as the public and politicians. Historic sites outside the country proper, but associated with the United States are listed. Properties can be nominated in a variety of forms, including individual properties, historic districts, multiple property submissions; the Register categorizes general listings into one of five types of properties: district, structure, building, or object. National Register Historic Districts are defined geographical areas consisting of contributing and non-contributing properties; some properties are added automatically to the National Register when they become administered by the National Park Service.
These include National Historic Landmarks, National Historic Sites, National Historical Parks, National Military Parks, National Memorials, some National Monuments. On October 15, 1966, the Historic Preservation Act created the National Register of Historic Places and the corresponding State Historic Preservation Offices; the National Register consisted of the National Historic Landmarks designated before the Register's creation, as well as any other historic sites in the National Park system. Approval of the act, amended in 1980 and 1992, represented the first time the United States had a broad-based historic preservation policy; the 1966 act required those agencies to work in conjunction with the SHPO and an independent federal agency, the Advisory Council on Historic Preservation, to confront adverse effects of federal activities on historic preservation. To administer the newly created National Register of Historic Places, the National Park Service of the U. S. Department of the Interior, with director George B.
Hartzog Jr. established an administrative division named the Office of Archeology and Historic Preservation. Hartzog charged OAHP with creating the National Register program mandated by the 1966 law. Ernest Connally was the Office's first director. Within OAHP new divisions were created to deal with the National Register; the division administered several existing programs, including the Historic Sites Survey and the Historic American Buildings Survey, as well as the new National Register and Historic Preservation Fund. The first official Keeper of the Register was an architectural historian. During the Register's earliest years in the late 1960s and early 1970s, organization was lax and SHPOs were small and underfunded. However, funds were still being supplied for the Historic Preservation Fund to provide matching grants-in-aid to listed property owners, first for house museums and institutional buildings, but for commercial structures as well. A few years in 1979, the NPS history programs affiliated with both the U.
S. National Parks system and the National Register were categorized formally into two "Assistant Directorates." Established were the Assistant Directorate for Archeology and Historic Preservation and the Assistant Directorate for Park Historic Preservation. From 1978 until 1981, the main agency for the National Register was the Heritage Conservation and Recreation Service of the United States Department of the Interior. In February 1983, the two assistant directorates were merged to promote efficiency and recognize the interdependency of their programs. Jerry L. Rogers was selected to direct this newly merged associate directorate, he was described as a skilled administrator, sensitive to the need for the NPS to work with SHPOs, local governments. Although not described in detail in the 1966 act, SHPOs became integral to the process of listing properties on the National Register; the 1980 amendments of the 1966 law further defined the responsibilities of SHPOs concerning the National Register.
Several 1992 amendments of the NHPA added a category to the National Register, known as Traditional Cultural Properties: those properties associated with Native American or Hawaiian groups
1940 United States Census
The Sixteenth United States Census, conducted by the Census Bureau, determined the resident population of the United States to be 132,164,569, an increase of 7.3 percent over the 1930 population of 123,202,624 people. The census date of record was April 1, 1940. A number of new questions were asked including where people were 5 years before, highest educational grade achieved, information about wages; this census introduced sampling techniques. Other innovations included a field test of the census in 1939; this was the first census in which every state had a population greater than 100,000. The 1940 census collected the following information: In addition, a sample of individuals were asked additional questions covering age at first marriage and other topics. Full documentation on the 1940 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series. Following completion of the census, the original enumeration sheets were microfilmed; as required by Title 13 of the U.
S. Code, access to identifiable information from census records was restricted for 72 years. Non-personally identifiable information Microdata from the 1940 census is available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System. On April 2, 2012—72 years after the census was taken—microfilmed images of the 1940 census enumeration sheets were released to the public by the National Archives and Records Administration; the records are indexed only by enumeration district upon initial release.

North Carolina is a state in the southeastern region of the United States. It borders South Carolina and Georgia to the south, Tennessee to the west, Virginia to the north, the Atlantic Ocean to the east. North Carolina is the 28th-most extensive and the 9th-most populous of the U. S. states. The state is divided into 100 counties; the capital is Raleigh, which along with Durham and Chapel Hill is home to the largest research park in the United States. The most populous municipality is Charlotte, the second-largest banking center in the United States after New York City; the state has a wide range of elevations, from sea level on the coast to 6,684 feet at Mount Mitchell, the highest point in North America east of the Mississippi River. The climate of the coastal plains is influenced by the Atlantic Ocean. Most of the state falls in the humid subtropical climate zone. More than 300 miles from the coast, the western, mountainous part of the state has a subtropical highland climate. Woodland-culture Native Americans were in the area around 1000 BCE.
During this time, important buildings were constructed as flat-topped buildings. By 1550, many groups of American Indians lived in present-day North Carolina, including Chowanoke, Pamlico, Coree, Cape Fear Indians, Waxhaw and Catawba. Juan Pardo explored the area in 1566–1567, establishing Fort San Juan in 1567 at the site of the Native American community of Joara, a Mississippian culture regional chiefdom in the western interior, near the present-day city of Morganton; the fort lasted only 18 months. A expedition by Philip Amadas and Arthur Barlowe followed in 1584, at the direction of Sir Walter Raleigh. In June 1718, the pirate Blackbeard ran his flagship, the Queen Anne's Revenge, aground at Beaufort Inlet, North Carolina, in present-day Carteret County. After the grounding her crew and supplies were transferred to smaller ships. In November, after appealing to the governor of North Carolina, who promised safe-haven and a pardon, Blackbeard was killed in an ambush by troops from Virginia.
In 1996 Intersal, Inc. a private firm, discovered the remains of a vessel to be the Queen Anne's Revenge, added to the US National Register of Historic Places. North Carolina became one of the English Thirteen Colonies and with the territory of South Carolina was known as the Province of North-Carolina; the northern and southern parts of the original province separated in 1729. Settled by small farmers, sometimes having a few slaves, who were oriented toward subsistence agriculture, the colony lacked cities or towns. Pirates menaced the coastal settlements. Growth was strong in the middle of the 18th century, as the economy attracted Scots-Irish, Quaker and German immigrants. A majority of the colonists supported the American Revolution, a smaller number of Loyalists than in some other colonies such as Georgia, South Carolina, New York. During colonial times, Edenton served as the state capital beginning in 1722, New Bern was selected as the capital in 1766. Construction of Tryon Palace, which served as the residence and offices of the provincial governor William Tryon, began in 1767 and was completed in 1771.
In 1788 Raleigh was chosen as the site of the new capital, as its central location protected it from coastal attacks. Established in 1792 as both county seat and state capital, the city was named after Sir Walter Raleigh, sponsor of Roanoke, the "lost colony" on Roanoke Island; the population of the colony more than quadrupled from 52,000 in 1740 to 270,000 in 1780 from high immigration from Virginia and Pennsylvania plus immigrants from abroad. North Carolina made the smallest per-capita contribution to the war of any state, as only 7,800 men joined the Continental Army under General George Washington. There was some military action in 1780–81. Many Carolinian frontiersmen had moved west over the mountains, into the Washington District, but in 1789, following the Revolution, the state was persuaded to relinquish its claim to the western lands, it ceded them to the national government so that the Northwest Territory could be organized and managed nationally. After 1800, cotton and tobacco became important export crops.
The eastern half of the state the Tidewater region, developed a slave society based on a plantation system and slave labor. Many free people of color migrated to the frontier along with their European-American neighbors, where the social system was looser. By 1810, nearly 3 percent of the free population consisted of free people of color, who numbered more than 10,000; the western areas were dominated by white families Scots-Irish, who operated small subsistence farms. In the early national period, the state became a center of Jeffersonian and Jacksonian democracy, with a strong Whig presence in the West. After Nat Turner's slave uprising in 1831, North Carolina and other southern states reduced the rights of free blacks. In 1835 the legislature withdrew their right to vote. On May 20, 1861, North Carolina was the last of the Confederate states to declare secession from the Union, 13 days after the Tennessee legislature voted for secession; some 125,000 North Carolinians served in the military.
An earthquake is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities; the seismicity, or seismic activity, of an area is the frequency and size of earthquakes experienced over a period of time. The word tremor is used for non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground; when the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can trigger landslides, volcanic activity. In its most general sense, the word earthquake is used to describe any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused by rupture of geological faults, but by other events such as volcanic activity, mine blasts, nuclear tests.
An earthquake's point of initial rupture is called its hypocenter. The epicenter is the point at ground level directly above the hypocenter. Tectonic earthquakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane; the sides of a fault move past each other smoothly and aseismically only if there are no irregularities or asperities along the fault surface that increase the frictional resistance. Most fault surfaces do have such asperities and this leads to a form of stick-slip behavior. Once the fault has locked, continued relative motion between the plates leads to increasing stress and therefore, stored strain energy in the volume around the fault surface; this continues until the stress has risen sufficiently to break through the asperity allowing sliding over the locked portion of the fault, releasing the stored energy. This energy is released as a combination of radiated elastic strain seismic waves, frictional heating of the fault surface, cracking of the rock, thus causing an earthquake.
This process of gradual build-up of strain and stress punctuated by occasional sudden earthquake failure is referred to as the elastic-rebound theory. It is estimated that only 10 percent or less of an earthquake's total energy is radiated as seismic energy. Most of the earthquake's energy is used to power the earthquake fracture growth or is converted into heat generated by friction. Therefore, earthquakes lower the Earth's available elastic potential energy and raise its temperature, though these changes are negligible compared to the conductive and convective flow of heat out from the Earth's deep interior. There are three main types of fault, all of which may cause an interplate earthquake: normal and strike-slip. Normal and reverse faulting are examples of dip-slip, where the displacement along the fault is in the direction of dip and movement on them involves a vertical component. Normal faults occur in areas where the crust is being extended such as a divergent boundary. Reverse faults occur in areas.
Strike-slip faults are steep structures where the two sides of the fault slip horizontally past each other. Many earthquakes are caused by movement on faults that have components of both dip-slip and strike-slip. Reverse faults those along convergent plate boundaries are associated with the most powerful earthquakes, megathrust earthquakes, including all of those of magnitude 8 or more. Strike-slip faults continental transforms, can produce major earthquakes up to about magnitude 8. Earthquakes associated with normal faults are less than magnitude 7. For every unit increase in magnitude, there is a thirtyfold increase in the energy released. For instance, an earthquake of magnitude 6.0 releases 30 times more energy than a 5.0 magnitude earthquake and a 7.0 magnitude earthquake releases 900 times more energy than a 5.0 magnitude of earthquake. An 8.6 magnitude earthquake releases the same amount of energy as 10,000 atomic bombs like those used in World War II. This is so because the energy released in an earthquake, thus its magnitude, is proportional to the area of the fault that ruptures and the stress drop.
Therefore, the longer the length and the wider the width of the faulted area, the larger the resulting magnitude. The topmost, brittle part of the Earth's crust, the cool slabs of the tectonic plates that are descending down into the hot mantle, are the only parts of our planet which can store elastic energy and release it in fault ruptures. Rocks hotter than about 300 °C flow in response to stress; the maximum observed lengths of ruptures and mapped faults are 1,000 km. Examples are the earthquakes in Chile, 1960; the longest earthquake ruptures on strike-slip faults, like the San Andreas Fault, the North Anatolian Fault in Turkey and the Denali Fault in Alaska, are about half to one third as long as the lengths along subducting plate margins, those along normal faults are shorter. The most important parameter controlling the maximum earthquake magnitude on a fault is however not the maximum available length, but the available width because the latter varies by a factor of 20. Along converging plate margins, the dip angle of the rupture plane is shallow about 10 de
