United States Geological Survey
The United States 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, the natural hazards that threaten it; the organization has four major science disciplines, concerning biology, geography and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility; the USGS is a bureau of the United States Department of the Interior. The USGS employs 8,670 people and is headquartered in Reston, Virginia; the USGS has major offices near Lakewood, Colorado, at the Denver Federal Center, 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 hundredth anniversary, was "Earth Science in the Public Service." Since 2012, the USGS science focus is directed at six topical "Mission Areas", namely Climate and Land Use Change, Core Science Systems, Ecosystems and Minerals and Environmental Health, Natural Hazards, Water.
In December 2012, the USGS split the Energy and Minerals and Environmental Health Mission Area resulting in seven topical Mission Areas, with the two new areas being: Energy and Minerals and Environmental Health. Administratively, it is divided into six Regional Units. Other specific programs include: Earthquake Hazards Program monitors earthquake activity worldwide; the National Earthquake Information Center in Golden, Colorado on the campus of the Colorado School of Mines detects the location and magnitude of global earthquakes. The USGS runs or supports several regional monitoring networks in the United States under the umbrella of the Advanced National Seismic System; the USGS informs authorities, emergency responders, the media, the public, both domestic and worldwide, about significant earthquakes. It maintains long-term archives of earthquake data for scientific and engineering research, it conducts and supports research on long-term seismic hazards. USGS has released the UCERF California earthquake forecast.
As of 2005, the agency is working to create a National Volcano Early Warning System by improving the instrumentation monitoring the 169 volcanoes in U. S. territory and by establishing methods for measuring the relative threats posed at each site. The USGS National Geomagnetism Program monitors the magnetic field at magnetic observatories and distributes magnetometer data in real time; the USGS collaborates with Canadian and Mexican government scientists, along with the Commission for Environmental Cooperation, to produce the North American Environmental Atlas, used to depict and track environmental issues for a continental perspective. The USGS operates the streamgaging network for the United States, with over 7400 streamgages. Real-time streamflow data are available online. National Climate Change and Wildlife Science Center implements partner-driven science to improve understanding of past and present land use change, develops relevant climate and land use forecasts, identifies lands and communities that are most vulnerable to adverse impacts of change from the local to global scale.
Since 1962, the Astrogeology Research Program has been involved in global and planetary exploration and mapping. In collaboration with Stanford University, the USGS operates the USGS-Stanford Ion Microprobe Laboratory, a world-class analytical facility for U--Pb geochronology and trace element analyses of minerals and other earth materials. USGS operates a number of water related programs, notably the National Streamflow Information Program and National Water-Quality Assessment Program. USGS Water data is publicly available from their National Water Information System database; the USGS operates the National Wildlife Health Center, whose mission is "to serve the nation and its natural resources by providing sound science and technical support, to disseminate information to promote science-based decisions affecting wildlife and ecosystem health. The NWHC provides information, technical assistance, research and leadership on national and international wildlife health issues." It is the agency responsible for surveillance of H5N1 avian influenza outbreaks in the United States.
The USGS runs 17 biological research centers in the United States, including the Patuxent Wildlife Research Center. The USGS is investigating collaboration with the social networking site Twitter to allow for more rapid construction of ShakeMaps; the USGS produces several national series of topographic maps which vary in scale and extent, with some wide gaps in coverage, notably the complete absence of 1:50,000 scale topographic maps or their equivalent. The largest and best-known topographic series is the 7.5-minute, 1:24,000 scale, quadrangle, a non-metric scale unique to the United States. Each of these maps covers an area bounded by two lines of latitude and two lines of longitude spaced 7.5 minutes apart. Nearly 57,000 individual maps in this series cover the 48 contiguous states, Hawaii, U. S. territories, areas of Alaska near Anchorage and Prudhoe Bay. The area covered by each map varies with the latitude of its represented location due to convergence of the meridians. At lower latitudes, near 30° north, a 7.5-minute quadrangle contains an area of about 64 square miles.
At 49° north latitude, 49 square miles are contained within a quadrangle of that size. As a unique non-metric map scale, the 1:24,000 scale requires a separate and specialized romer scale for pl
In law, an unincorporated area is a region of land, not governed by a local municipal corporation. Municipalities dissolve or disincorporate, which may happen if they become fiscally insolvent, services become the responsibility of a higher administration. Widespread unincorporated communities and areas are a distinguishing feature of the United States and Canada. In most other countries of the world, there are either no unincorporated areas at all, or these are rare. Unlike many other countries, Australia has only one level of local government beneath state and territorial governments. A local government area contains several towns and entire cities. Thus, aside from sparsely populated areas and a few other special cases all of Australia is part of an LGA. Unincorporated areas are in remote locations, cover vast areas or have small populations. Postal addresses in unincorporated areas, as in other parts of Australia use the suburb or locality names gazetted by the relevant state or territorial government.
Thus, there is any ambiguity regarding addresses in unincorporated areas. The Australian Capital Territory is in some sense an unincorporated area; the territorial government is directly responsible for matters carried out by local government. The far west and north of New South Wales constitutes the Unincorporated Far West Region, sparsely populated and warrants an elected council. A civil servant in the state capital manages such matters; the second unincorporated area of this state is Lord Howe Island. In the Northern Territory, 1.45% of the total area and 4.0% of the population are in unincorporated areas, including Unincorporated Top End Region, areas covered by the Darwin Rates Act—Nhulunbuy, Alyangula on Groote Eylandt in the northern region, Yulara in the southern region. In South Australia, 60% of the area is unincorporated and communities located within can receive municipal services provided by a state agency, the Outback Communities Authority. Victoria has 10 small unincorporated areas, which are either small islands directly administered by the state or ski resorts administered by state-appointed management boards.
Western Australia is exceptional in two respects. Firstly, the only remote area, unincorporated is the Abrolhos Islands, uninhabited and controlled by the WA Department of Fisheries. Secondly, the other unincorporated areas are A-class reserves either in, or close to, the Perth metropolitan area, namely Rottnest Island and Kings Park. In Canada, depending on the province, an unincorporated settlement is one that does not have a municipal council that governs over the settlement, it is but not always, part of a larger municipal government. This can range from small hamlets to large urbanized areas that are similar in size to towns and cities. For example, the urban service areas of Fort McMurray and Sherwood Park, of the Regional Municipality of Wood Buffalo and Strathcona County would be the fifth and sixth largest cities in Alberta if they were incorporated. In British Columbia, unincorporated settlements lie outside municipal boundaries and are administered directly by regional/county-level governments similar to the American system.
Unincorporated settlements with a population of between 100 and 1,000 residents may have the status of designated place in Canadian census data. In some provinces, large tracts of undeveloped wilderness or rural country are unorganized areas that fall directly under the provincial jurisdiction; some unincorporated settlements in such unorganized areas may have some types of municipal services provided to them by a quasi-governmental agency such as a local services board in Ontario. In New Brunswick where a significant population live in a Local Service District and services may come directly from the province; the entire area of the Czech Republic is divided into municipalities, with the only exception being 4 military areas. These are parts of the regions and do not form self-governing municipalities, but are rather governed by military offices, which are subordinate to the Ministry of Defense. † Brdy Military Area was abandoned by the Army in 2015 and converted into Landscape park, with its area being incorporated either into existing municipalities or municipalities newly established from the existing settlements.
The other four Military Areas were reduced in size in 2015 too. The decisions on whether the settlements join existing municipalities or form new ones are decided in plebiscites. Since Germany has no administrative level comparable to the townships of other countries, the vast majority of the country, close to 99%, is organized in municipalities consisting of multiple settlements which are not considered to be unincorporated; because these settlements lack a council of their own, there is an Ortsvorsteher / Ortsvorsteherin appointed by the municipal council, except in the smallest villages. In 2000, the number of unincorporated areas in Germany, called gemeindefreie Gebiete or singular gemeindefreies Gebiet, was 295 with a total area of 4,890.33 km² and around 1.4% of its territory.

Byrdstown is a town in Pickett County, United States. The population was 803 at the 2010 census, it is the county seat of Pickett County. Byrdstown was established in 1879 as a county seat for the newly formed Pickett County; the town, where several families lived, was named for Colonel Robert K. Byrd, a state senator whose district included the new county. Byrdstown was incorporated in 1917. Former Secretary of State Cordell Hull — who played a pivotal role in the creation of the United Nations— was born just west of Byrdstown; the Pickett County Courthouse, built in 1935, the Cordell Hull Birthplace are both listed on the National Register of Historic Places. Other historical sites include the Amonett House at the junction of TN-325 and TN-111. Byrdstown is located at 36°34′21″N 85°8′14″W; the town is situated in a hilly area on the Highland Rim, a few miles south of the Kentucky state line. Byrdstown lies south of the Wolf River, north of the Obey River, east of Dale Hollow Lake, where the two rivers converge.
Tennessee State Route 325 traverses Byrdstown from west to east following West Main Street and East Main Street. This highway connects Byrdstown with the Dale Hollow Lake and Cordell Hull Birthplace State Park areas to the west, the rural parts of central Pickett County to the east. Tennessee State Route 111, which intersects SR 325 in western Byrdstown, connects the town with Livingston to the southwest, Static at the state line to the north. At Static, the highway terminates at an intersection with U. S. Route 127, with the latter continuing northward to Kentucky. According to the United States Census Bureau, the town has a total area of 1.5 square miles, all of it land. As of the census of 2000, there were 903 people, 395 households, 233 families residing in the town; the population density was 587.5 people per square mile.

Pickett County, Tennessee
Pickett County is a county located in the U. S. state of Tennessee. As of the 2010 census, the population was 5,077, its county seat is Byrdstown. The city of Byrdstown and the Kentucky town of Albany, 11 miles to the northeast, are positioned between two Army Corps of Engineers lakes: Dale Hollow Lake in Tennessee, Lake Cumberland, in Kentucky; the area is known as "Twin Lakes" and Byrdstown is noted as "The Gateway To Dale Hollow Lake". Every year thousands of people vacation at the many resorts situated along the lakes. Pickett County was created in 1879 from sections of Fentress counties, it was named for Howard L. Pickett, a member of the state legislature, instrumental in the county's formation. Nobel Peace Prize winner Cordell Hull had been born in one of the parcels of land set aside to create the new county. Hull would be honored for his role in organizing the World War II diplomatic alliance that became the United Nations. According to the U. S. Census Bureau, the county has a total area of 174 square miles, of which 163 square miles is land and 12 square miles is water.
It is the fourth-smallest county in Tennessee by land third-smallest by total area. The eastern part of the county, much of, part of Pickett State Forest, lies atop the Cumberland Plateau, while the western, more populated half is located on the Highland Rim; the Wolf River and the Obey River, the lower parts of which are part of Dale Hollow Lake, pass through the county. The rivers converge just west of the county's border with Clay County. Streams in the far eastern section of the county are part of the watershed of the Big South Fork of the Cumberland River.

Tennessee is a state located in the southeastern region of the United States. Tennessee is the 16th most populous of the 50 United States. Tennessee is bordered by Kentucky to the north, Virginia to the northeast, North Carolina to the east, Georgia and Mississippi to the south, Arkansas to the west, Missouri to the northwest; the Appalachian Mountains dominate the eastern part of the state, the Mississippi River forms the state's western border. Nashville is the state's capital and largest city, with a 2017 population of 667,560. Tennessee's second largest city is Memphis, which had a population of 652,236 in 2017; the state of Tennessee is rooted in the Watauga Association, a 1772 frontier pact regarded as the first constitutional government west of the Appalachians. What is now Tennessee was part of North Carolina, part of the Southwest Territory. Tennessee was admitted to the Union as the 16th state on June 1, 1796. Tennessee was the last state to leave the Union and join the Confederacy at the outbreak of the American Civil War in 1861.
Occupied by Union forces from 1862, it was the first state to be readmitted to the Union at the end of the war. Tennessee furnished more soldiers for the Confederate Army than any other state besides Virginia, more soldiers for the Union Army than the rest of the Confederacy combined. Beginning during Reconstruction, it had competitive party politics, but a Democratic takeover in the late 1880s resulted in passage of disenfranchisement laws that excluded most blacks and many poor whites from voting; this reduced competition in politics in the state until after passage of civil rights legislation in the mid-20th century. In the 20th century, Tennessee transitioned from an agrarian economy to a more diversified economy, aided by massive federal investment in the Tennessee Valley Authority and, in the early 1940s, the city of Oak Ridge; this city was established to house the Manhattan Project's uranium enrichment facilities, helping to build the world's first atomic bombs, two of which were dropped on Imperial Japan near the end of World War II.
Tennessee's major industries include agriculture and tourism. Poultry and cattle are the state's primary agricultural products, major manufacturing exports include chemicals, transportation equipment, electrical equipment; the Great Smoky Mountains National Park, the nation's most visited national park, is headquartered in the eastern part of the state, a section of the Appalachian Trail follows the Tennessee-North Carolina border. Other major tourist attractions include the Tennessee Aquarium in Chattanooga; the earliest variant of the name that became Tennessee was recorded by Captain Juan Pardo, the Spanish explorer, when he and his men passed through an American Indian village named "Tanasqui" in 1567 while traveling inland from South Carolina. In the early 18th century, British traders encountered a Cherokee town named Tanasi in present-day Monroe County, Tennessee; the town was located on a river of the same name, appears on maps as early as 1725. It is not known whether this was the same town as the one encountered by Juan Pardo, although recent research suggests that Pardo's "Tanasqui" was located at the confluence of the Pigeon River and the French Broad River, near modern Newport.
The meaning and origin of the word are uncertain. Some accounts suggest, it has been said to mean "meeting place", "winding river", or "river of the great bend". According to ethnographer James Mooney, the name "can not be analyzed" and its meaning is lost; the modern spelling, Tennessee, is attributed to James Glen, the governor of South Carolina, who used this spelling in his official correspondence during the 1750s. The spelling was popularized by the publication of Henry Timberlake's "Draught of the Cherokee Country" in 1765. In 1788, North Carolina created "Tennessee County", the third county to be established in what is now Middle Tennessee; when a constitutional convention met in 1796 to organize a new state out of the Southwest Territory, it adopted "Tennessee" as the name of the state. Tennessee is known as The Volunteer State, a nickname some claimed was earned during the War of 1812 because of the prominent role played by volunteer soldiers from Tennessee during the Battle of New Orleans.
Other sources differ on the origin of the state nickname. This explanation is more because President Polk's call for 2,600 nationwide volunteers at the beginning of the Mexican–American War resulted in 30,000 volunteers from Tennessee alone in response to the death of Davy Crockett and appeals by former Tennessee Governor and Texas politician, Sam Houston. Tennessee borders eight other states: Virginia to the north. Tennessee is tied with Missouri as the state bordering the most other states; the state is trisected by the Tennessee River. The highest point in the state is Clingmans Dome at 6,643 feet (
A county seat is an administrative center, seat of government, or capital city of a county or civil parish. The term is used in Canada, Romania and the United States. County towns have a similar function in the United Kingdom and Republic of Ireland, in Jamaica. In most of the United States, counties are the political subdivisions of a state; the city, town, or populated place that houses county government is known as the seat of its respective county. The county legislature, county courthouse, sheriff's department headquarters, hall of records and correctional facility are located in the county seat though some functions may be located or conducted in other parts of the county if it is geographically large. A county seat is but not always, an incorporated municipality; the exceptions include the county seats of counties that have no incorporated municipalities within their borders, such as Arlington County, Virginia. Ellicott City, the county seat of Howard County, is the largest unincorporated county seat in the United States, followed by Towson, the county seat of Baltimore County, Maryland.
Some county seats may not be incorporated in their own right, but are located within incorporated municipalities. For example, Cape May Court House, New Jersey, though unincorporated, is a section of Middle Township, an incorporated municipality. In some of the colonial states, county seats include or included "Court House" as part of their name. In the Canadian provinces of Prince Edward Island, New Brunswick, Nova Scotia, the term "shire town" is used in place of county seat. County seats in Taiwan are the administrative centers of the counties. There are 13 county seats in Taiwan, which are in the forms of county-administered city, urban township or rural township. Most counties have only one county seat. However, some counties in Alabama, Georgia, Kentucky, Mississippi, New Hampshire, New York, Vermont have two or more county seats located on opposite sides of the county. An example is Harrison County, which lists both Biloxi and Gulfport as county seats; the practice of multiple county seat towns dates from the days.
There have been few efforts to eliminate the two-seat arrangement, since a county seat is a source of pride for the towns involved. There are 36 counties with multiple county seats in 11 states: Coffee County, Alabama St. Clair County, Alabama Arkansas County, Arkansas Carroll County, Arkansas Clay County, Arkansas Craighead County, Arkansas Franklin County, Arkansas Logan County, Arkansas Mississippi County, Arkansas Prairie County, Arkansas Sebastian County, Arkansas Yell County, Arkansas Columbia County, Georgia Lee County, Iowa Campbell County, Kentucky Kenton County, Kentucky Essex County, Massachusetts Middlesex County, Massachusetts Plymouth County, Massachusetts Bolivar County, Mississippi Carroll County, Mississippi Chickasaw County, Mississippi Harrison County, Mississippi Hinds County, Mississippi Jasper County, Mississippi Jones County, Mississippi Panola County, Mississippi Tallahatchie County, Mississippi Yalobusha County, Mississippi Jackson County, Missouri Hillsborough County, New Hampshire Seneca County, New York Bennington County, Vermont In New England, the town, not the county, is the primary division of local government.
Counties in this region have served as dividing lines for the states' judicial systems. Connecticut and Rhode Island have no county level of thus no county seats. In Vermont and Maine the county seats are designated shire towns. County government consists only of a Superior Court and Sheriff, both located in the respective shire town. Bennington County has two shire towns. In Massachusetts, most government functions which would otherwise be performed by county governments in other states are performed by town or city governments; as such, Massachusetts has dissolved many of its county governments, the state government now operates the registries of deeds and sheriff's offices in those counties. In Virginia, a county seat may be an independent city surrounded by, but not part of, the county of which it is the administrative center. Two counties in South Dakota have their county seat and government services centered in a neighboring county, their county-level services are provided by Fall River Tripp County, respectively.
In Louisiana, divided into parishes rather than counties, county seats are referred to as parish seats. Alaska is divided into boroughs rather than counties; the Unorganized Borough, which covers 49 % of Alaska's area, has equivalent. The state with the most counties is Texas, with 254, the state with the fewest counties is Delaware, with 3.

A ghost town is an abandoned village, town, or city one that contains substantial visible remains. A town becomes a ghost town because the economic activity that supported it has failed, or due to natural or human-caused disasters such as floods, prolonged droughts, government actions, uncontrolled lawlessness, pollution, or nuclear disasters; the term can sometimes refer to cities and neighbourhoods that are still populated, but less so than in past years. Some ghost towns those that preserve period-specific architecture, have become tourist attractions; some examples are Bannack, Centralia and South Pass City in the United States, Barkerville in Canada, Craco in Italy, Elizabeth Bay and Kolmanskop in Namibia, Pripyat in Ukraine, Danushkodi in India. The town of Plymouth on the Caribbean island of Montserrat is a ghost town, the de jure capital of Montserrat, it was rendered uninhabitable by volcanic ash from an eruption. The definition of a ghost town varies between individuals, between cultures.
Some writers discount settlements that were abandoned as a result of a natural or human-made disaster or other causes using the term only to describe settlements that were deserted because they were no longer economically viable. Some believe. Whether or not the settlement must be deserted, or may contain a small population, is a matter for debate. Though, the term is used in a looser sense, encompassing any and all of these definitions; the American author Lambert Florin's preferred definition of a ghost town was "a shadowy semblance of a former self". Factors leading to abandonment of towns include depleted natural resources, economic activity shifting elsewhere and roads bypassing or no longer accessing the town, human intervention, massacres and the shifting of politics or fall of empires. A town can be abandoned when it is part of an exclusion zone due to natural or man-made causes. Ghost towns may result when the single activity or resource that created a boomtown is depleted or the resource economy undergoes a "bust".
Boomtowns can decrease in size as fast as they grew. Sometimes, all or nearly the entire population can desert the town; the dismantling of a boomtown can occur on a planned basis. Mining companies nowadays will create a temporary community to service a mine site, building all the accommodation and services required, remove them once the resource has been extracted. Modular buildings can be used to facilitate the process. A gold rush would bring intensive but short-lived economic activity to a remote village, only to leave a ghost town once the resource was depleted. In some cases, multiple factors may remove the economic basis for a community. S. Route 66 suffered both mine closures when the resources were depleted and loss of highway traffic as US 66 was diverted away from places like Oatman, Arizona onto a more direct path. Mine and pulp mill closures have led to many ghost towns in British Columbia, Canada including several recent ones: Ocean Falls which closed in 1973 after the pulp mill was decommissioned, Kitsault B.
C. whose molybdenum mine shut after only 18 months in 1982 and Cassiar whose asbestos mine operated from 1952 to 1992. In other cases, the reason for abandonment can arise from a town's intended economic function shifting to another, nearby place; this happened to Collingwood, Queensland in Outback Australia when nearby Winton outperformed Collingwood as a regional centre for the livestock-raising industry. The railway reached Winton in 1899, linking it with the rest of Queensland, Collingwood was a ghost town by the following year; the Middle East has many ghost towns that were created when the shifting of politics or the fall of empires caused capital cities to be or economically unviable, such as Ctesiphon. The rise of condominium investment caused for real estate bubbles leads to a ghost town, as real estate prices rise and affordable housing becomes less available; such examples include China and Canada, where housing is used as an investment rather than for habitation. Railroads and roads bypassing or no longer reaching a town can create a ghost town.
This was the case in many of the ghost towns along Ontario's historic Opeongo Line, along U. S. Route 66 after motorists bypassed the latter on the faster moving highways I-44 and I-40; some ghost towns were founded along railways where steam trains would stop at periodic intervals to take on water. Amboy, California was part of one such series of villages along the Atlantic and Pacific Railroad across the Mojave Desert. River re-routing is one example being the towns along the Aral Sea. Ghost towns may be created when land is expropriated by a government, residents are required to relocate. One example is the village of Tyneham in Dorset, acquired during World War II to build an artillery range. A similar situation occurred in the U. S. when NASA acquired land to construct the John C. Stennis Space Center, a rocket testing facility in Hancock County, Mississippi; this required NASA to acquire a large (approximately 34-square-mile (88
