International Union for Conservation of Nature
–
The International Union for Conservation of Nature is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in gathering and analysis, research, field projects, advocacy, lobbying. IUCNs mission is to influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of resources is equitable. Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to equality, poverty alleviation. Unlike other international NGOs, IUCN does not itself aim to mobilize the public in support of nature conservation and it tries to influence the actions of governments, business and other stakeholders by providing information and advice, and through lobbying and partnerships. The organization is best known to the public for compiling and publishing the IUCN Red List. IUCN has a membership of over 1200 governmental and non-governmental organizations, some 11,000 scientists and experts participate in the work of IUCN commissions on a voluntary basis. It employs approximately 1000 full-time staff in more than 60 countries and its headquarters are in Gland, Switzerland. IUCN has observer and consultative status at the United Nations, and plays a role in the implementation of several conventions on nature conservation. It was involved in establishing the World Wide Fund for Nature, in the past, IUCN has been criticized for placing the interests of nature over those of indigenous peoples. In recent years, its relations with the business sector have caused controversy. It was previously called the International Union for Protection of Nature, establishment In 1947, the Swiss League for the Protection of Nature organised an international conference on the protection of nature in Brunnen. It is considered to be the first government-organized non-governmental organization, the initiative to set up the new organisation came from UNESCO and especially from its first Director General, the British biologist Julian Huxley. At the time of its founding IUPN was the international organisation focusing on the entire spectrum of nature conservation Early years. Its secretariat was located in Brussels and its first work program focused on saving species and habitats, increasing and applying knowledge, advancing education, promoting international agreements and promoting conservation. Providing a solid base for conservation action was the heart of all activities. IUPN and UNESCO were closely associated and they jointly organized the 1949 Conference on Protection of Nature. In preparation for this conference a list of endangered species was drawn up for the first time

National park
–
A national park is a park in use for conservation purposes. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns, although individual nations designate their own national parks differently, there is a common idea, the conservation of wild nature for posterity and as a symbol of national pride. An international organization, the International Union for Conservation of Nature, although Yellowstone was not officially termed a national park in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. The first area to use national park in its legislation was the USs Mackinac Island. Australias Royal National Park, established in 1879, was the third official national park. In 1895 ownership of Mackinac Island was transferred to the State of Michigan as a state park, as a result, Australias Royal National Park is by some considerations the second oldest national park now in existence. The largest national park in the meeting the IUCN definition is the Northeast Greenland National Park. According to the IUCN,6,555 national parks worldwide met its criteria in 2006, IUCN is still discussing the parameters of defining a national park. National parks are almost always open to visitors, in 1971, these criteria were further expanded upon leading to more clear and defined benchmarks to evaluate a national park. In 1810, the English poet William Wordsworth described the Lake District as a sort of property, in which every man has a right and interest who has an eye to perceive. It was known as Hot Springs Reservation, but no authority was established. Federal control of the area was not clearly established until 1877, John Muir is today referred to as the Father of the National Parks due to his work in Yosemite. He published two articles in The Century Magazine, which formed the base for the subsequent legislation. President Abraham Lincoln signed an Act of Congress on July 1,1864, ceding the Yosemite Valley, according to this bill, private ownership of the land in this area was no longer possible. The state of California was designated to manage the park for use, resort. Leases were permitted for up to ten years and the proceeds were to be used for conservation, a public discussion followed this first legislation of its kind and there was a heated debate over whether the government had the right to create parks. The perceived mismanagement of Yosemite by the Californian state was the reason why Yellowstone at its establishment six years later was put under national control, in 1872, Yellowstone National Park was established as the United States first national park, being also the worlds first national park. In some European countries, however, national protection and nature reserves already existed, such as Drachenfels, Yellowstone was part of a federally governed territory

S. states constituted as a commonwealth, originally a part of Virginia, in 1792 Kentucky became the 15th state to join the Union. Kentucky is the 37th most extensive and the 26th most populous of the 50 United States, Kentucky is known as the Bluegrass State, a nickname based on the bluegrass found in many of its pastures due to the fertile soil. One of the regions in Kentucky is the Bluegrass Region in central Kentucky. In 1776, the counties of Virginia beyond the Appalachian Mountains became known as Kentucky County, the precise etymology of the name is uncertain, but likely based on an Iroquoian name meaning the meadow or the prairie. Kentucky is situated in the Upland South, a significant portion of eastern Kentucky is part of Appalachia. Kentucky borders seven states, from the Midwest and the Southeast, West Virginia lies to the east, Virginia to the southeast, Tennessee to the south, Missouri to the west, Illinois and Indiana to the northwest, and Ohio to the north and northeast. Only Missouri and Tennessee, both of which border eight states, touch more, Kentuckys northern border is formed by the Ohio River and its western border by the Mississippi River. The official state borders are based on the courses of the rivers as they existed when Kentucky became a state in 1792, for instance, northbound travelers on U. S.41 from Henderson, after crossing the Ohio River, will be in Kentucky for about two miles. Ellis Park, a racetrack, is located in this small piece of Kentucky. Waterworks Road is part of the land border between Indiana and Kentucky. Kentucky has a part known as Kentucky Bend, at the far west corner of the state. It exists as an exclave surrounded completely by Missouri and Tennessee, Road access to this small part of Kentucky on the Mississippi River requires a trip through Tennessee. The epicenter of the powerful 1811–12 New Madrid earthquakes was near this area, much of the outer Bluegrass is in the Eden Shale Hills area, made up of short, steep, and very narrow hills. The Jackson Purchase and western Pennyrile are home to several bald cypress/tupelo swamps, located within the southeastern interior portion of North America, Kentucky has a climate that can best be described as a humid subtropical climate. Temperatures in Kentucky usually range from daytime summer highs of 87 °F to the low of 23 °F.

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

National Park Service
–
It was created on August 25,1916, by Congress through the National Park Service Organic Act and is an agency of the United States Department of the Interior. As of 2014, the NPS employs 21,651 employees who oversee 417 units, the National Park Service celebrated its centennial in 2016. National parks and national monuments in the United States were originally individually managed under the auspices of the Department of the Interior, the movement for an independent agency to oversee these federal lands was spearheaded by business magnate and conservationist Stephen Mather, as well as J. Horace McFarland. With the help of journalist Robert Sterling Yard, Mather ran a publicity campaign for the Department of the Interior and they wrote numerous articles that praised the scenic and historic qualities of the parks and their possibilities for educational, inspirational, and recreational benefits. This campaign resulted in the creation of a National Park Service, Mather became the first director of the newly formed NPS. On March 3,1933, President Herbert Hoover signed the Reorganization Act of 1933, the act would allow the President to reorganize the executive branch of the United States government. It wasnt until later that summer when the new President, Franklin D. Roosevelt, President Roosevelt agreed and issued two Executive orders to make it happen. In 1951, Conrad Wirth became director of the National Park Service, the demand for parks after the end of the World War II had left the parks overburdened with demands that could not be met. In 1952, with the support of President Dwight D. Eisenhower, he began Mission 66, New parks were added to preserve unique resources and existing park facilities were upgraded and expanded. In 1966, as the Park Service turned 50 years old, emphasis began to turn from just saving great and wonderful scenery, Director George Hartzog began the process with the creation of the National Lakeshores and then National Recreation Areas. Since its inception in 1916, the National Park Service has managed each of the United States national parks, Yellowstone National Park was the first national park in the United States. In 1872, there was no government to manage it. Yosemite National Park began as a park, the land for the park was donated by the federal government to the state of California in 1864 for perpetual conservation. Yosemite was later returned to federal ownership, at first, each national park was managed independently, with varying degrees of success. In Yellowstone, the staff was replaced by the U. S. Army in 1886. Due to the irregularities in managing these national treasures, Stephen Mather petitioned the government to improve the situation. In response, Secretary of the Interior Franklin K. Lane challenged him to lobby for creating a new agency, Mather was successful with the ratification of the National Park Service Organic Act in 1916. Later, the agency was given authority over other protected areas, the National Park System includes all properties managed by the National Park Service

World Heritage Site
–
A World Heritage Site is a landmark which has been officially recognized by the United Nations, specifically by the United Nations Educational, Scientific and Cultural Organization. Sites are selected on the basis of having cultural, historical, scientific or some form of significance. UNESCO regards these sites as being important to the interests of humanity. The programme catalogues, names, and conserves sites of outstanding cultural or natural importance to the common culture, under certain conditions, listed sites can obtain funds from the World Heritage Fund. The program was founded with the Convention Concerning the Protection of the Worlds Cultural and Natural Heritage, since then,192 state parties have ratified the convention, making it one of the most adhered to international instruments. As of July 2016,1052 sites are listed,814 cultural,203 natural, in 1959, the governments of Egypt and Sudan requested UNESCO to assist their countries to protect and rescue the endangered monuments and sites. In 1960, the Director-General of UNESCO launched an appeal to the Member States for an International Campaign to Save the Monuments of Nubia, the campaign, which ended in 1980, was considered a success. The project cost $80 million, about $40 million of which was collected from 50 countries, the projects success led to other safeguarding campaigns, saving Venice and its lagoon in Italy, the ruins of Mohenjo-daro in Pakistan, and the Borobodur Temple Compounds in Indonesia. UNESCO then initiated, with the International Council on Monuments and Sites, the United States initiated the idea of cultural conservation with nature conservation. The International Union for Conservation of Nature developed similar proposals in 1968, the Convention came into force on 17 December 1975. As of June 2016, it has been ratified by 192 states, including 188 UN member states plus the Cook Islands, the Holy See, Niue, a country must first list its significant cultural and natural sites, the result is called the Tentative List. A country may not nominate sites that have not been first included on the Tentative List, next, it can place sites selected from that list into a Nomination File. The Nomination File is evaluated by the International Council on Monuments and Sites and these bodies then make their recommendations to the World Heritage Committee. There are ten selection criteria – a site must meet at least one of them to be included on the list, up to 2004, there were six criteria for cultural heritage and four criteria for natural heritage. In 2005, this was modified so there is now only one set of ten criteria. Nominated sites must be of outstanding value and meet at least one of the ten criteria. Thus, the Geneva Convention treaty promulgates, Article 53, PROTECTION OF CULTURAL OBJECTS AND OF PLACES OF WORSHIP. There are 1,052 World Heritage Sites located in 165 States Party, of these,814 are cultural,203 are natural and 35 are mixed properties

Man and the Biosphere Programme
–
As of March 2016,669 biosphere reserves in 120 countries, including 16 transboundary sites, have been included in the World Network of Biosphere Reserves. Biosphere reserves are areas comprising terrestrial, marine and coastal ecosystems, each reserve promotes solutions reconciling the conservation of biodiversity with its sustainable use. Biosphere reserves are nominated by governments and remain under the sovereign jurisdiction of the states where they are located. Their status is internationally recognized. The buffer zone surrounds or adjoins the core areas, and is used for activities compatible with sound ecological practices that can reinforce scientific research, monitoring, training and education. The transition area is the part of the reserve where the greatest activity is allowed, fostering economic, participating countries establish MAB National Committees that ensure maximum national participation in the international programme, defining and implementing each country’s activities. MAB currently operates through 158 National Committees established among the 195 Members States, the agenda of the MAB Programme is defined by its main governing body, the International Coordinating Council. The MAB Council consists of 34 member states elected by UNESCO’s General Conference, the council elects a chair and five vice-chairpersons from each of UNESCO’s geopolitical regions, one of which functions as a rapporteur. Its staff members draw on expertise in many and varied disciplines, the programme can grant seed funding to assist countries in developing projects and/or to secure appropriate partnership contributions. The latest World Congress of Biosphere Reserves took place in Lima, Peru and this will be the 4th World Congress of Biosphere Reserves and it shall develop a new vision for the decade 2016–2025. The World Network of Biosphere Reserves is supported by different regional, sub-regional or thematic networks and these are as follows, The African Biosphere Reserves Network was created in 1996 and comprises 33 African countries. The ArabMAB Network was officially launched in 1997 and represents 18 Arab countries, the East Asian Biosphere Reserve Network was launched in 1994. Today, it consists of China, the Democratic People’s Republic of Korea, Japan, Kazakhstan, Mongolia, the Republic of Korea, euroMAB is the network of biosphere reserves in Europe and North America.

Green River (Kentucky)
–
The Green River is a 384-mile-long tributary of the Ohio River that rises in Lincoln County in south-central Kentucky. Tributaries of the Green River include the Barren River, the Nolin River, the Pond River, the river was named after Nathanael Greene, a general of the American Revolutionary War. Following the Revolutionary War, many veterans staked claims along the Green River as payment for their military service, the river valley also attracted a number of vagrants, earning it the dubious nickname Rogues Harbor. In 1842, the Green River was canalized, with a series of locks and dams being built to create a channel as far inland as Bowling Green. Four locks and dams were constructed on the Green River, and one lock and dam was built on the Barren River, a tributary that passed through Bowling Green. During the American Civil War, Confederate General John Hunt Morgan conducted daring raids through the Green River country, from which he reached into southern Indiana, in 1901, two additional locks and dams were opened on the Green River, which allowed river traffic to Mammoth Cave. In 1941, Mammoth Cave National Park was established, and the two locks and dams closed in 1950. In 1965, Lock and Dam #4 at Woodbury failed, this was the dam that locked both the Green and Barren rivers, in 1969, the United States Army Corps of Engineers impounded a section of the river, forming 8, 200-acre Green River Lake. The lake is now the primary feature of Green River Lake State Park, there is still one Native American tribe living on the Green River, the Southern Cherokee Nation of Kentucky. In 1893 Governor John Y. Brown recognized the Southern Cherokee Nation as an Indian tribe, the Green River flows through Mammoth Cave National Park, located along river miles 190 to 205. The 384-mile-long Green River, an important transportation artery for the industry, is open to traffic up to the closed Lock. Muhlenberg County, once the largest coal-producing county in the nation, benefits greatly from access to the river, in 2002, more than 10 million short tons were shipped on the river, primarily sub-bituminous coal, petroleum coke, and aluminum ore. The Green River is home to more than 150 fish species and this includes some of Kentuckys largest fish and some of the worlds rarest species of mussels. B. Cunningham wrote a series of 22 detective stories, all but one of which are set in a county through which the Green River flows and which feature Jess Roden, in 1969, Creedence Clearwater Revival released the album Green River.

Tributary
–
A tributary or affluent is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean, tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. A confluence, where two or more bodies of water together, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from, distributaries are most often found in river deltas. Right tributary and left tributary are terms stating the orientation of the relative to the flow of the main stem river. These terms are defined from the perspective of looking downstream, where tributaries have the same name as the river into which they feed, they are called forks. These are typically designated by compass direction, for example, the American River receives flow from its North, Middle, and South forks. The Chicago Rivers North Branch has the East, West, and Middle Fork, the South Branch has its South Fork, forks are sometimes designated as right or left. Here, the handedness is from the point of view of an observer facing upstream, for instance, Steer Creek has a left tributary which is called Right Fork Steer Creek. Tributaries are sometimes listed starting with those nearest to the source of the river, the Strahler Stream Order examines the arrangement of tributaries in a hierarchy of first, second, third, and higher orders, with the first-order tributary being typically the least in size. For example, a second-order tributary would be the result of two or more first-order tributaries combining to form the second-order tributary, another method is to list tributaries from mouth to source, in the form of a tree structure, stored as a tree data structure

Nolin River
–
The Nolin River is a 104-mile-long tributary of the Green River in central Kentucky in the United States. Via the Green and Ohio rivers, it is a part of the watershed of the Mississippi River. According to legend, Nolin River was so named when a group of hunters camped on a knoll near the river, the story continues the rest of the party returned to the knoll where someone said Here is the knoll, but no Lynn. The lost hunter was later found alive and well camped out at nearby Lynn Camp Creek, the United States Board on Geographic Names settled on Nolin River as the streams name in 1933. The Nolin then flows generally southwestwardly through or along the boundaries of Hardin, Grayson, Hart and it joins the Green River in the western part of Mammoth Cave National Park, about 2 miles northeast of Brownsville. In Edmonson County, a U. S. Army Corps of Engineers dam causes the river to form Nolin River Lake

Mexico
–
Mexico, officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States, to the south and west by the Pacific Ocean, to the southeast by Guatemala, Belize, and the Caribbean Sea, and to the east by the Gulf of Mexico. Covering almost two million square kilometers, Mexico is the sixth largest country in the Americas by total area, Mexico is a federation comprising 31 states and a federal district that is also its capital and most populous city. Other metropolises include Guadalajara, Monterrey, Puebla, Toluca, Tijuana, pre-Columbian Mexico was home to many advanced Mesoamerican civilizations, such as the Olmec, Toltec, Teotihuacan, Zapotec, Maya and Aztec before first contact with Europeans. In 1521, the Spanish Empire conquered and colonized the territory from its base in Mexico-Tenochtitlan, Three centuries later, this territory became Mexico following recognition in 1821 after the colonys Mexican War of Independence. The tumultuous post-independence period was characterized by instability and many political changes. The Mexican–American War led to the cession of the extensive northern borderlands, one-third of its territory. The Pastry War, the Franco-Mexican War, a civil war, the dictatorship was overthrown in the Mexican Revolution of 1910, which culminated with the promulgation of the 1917 Constitution and the emergence of the countrys current political system. Mexico has the fifteenth largest nominal GDP and the eleventh largest by purchasing power parity, the Mexican economy is strongly linked to those of its North American Free Trade Agreement partners, especially the United States. Mexico was the first Latin American member of the Organisation for Economic Co-operation and Development and it is classified as an upper-middle income country by the World Bank and a newly industrialized country by several analysts. By 2050, Mexico could become the fifth or seventh largest economy. The country is considered both a power and middle power, and is often identified as an emerging global power. Due to its culture and history, Mexico ranks first in the Americas. Mexico is a country, ranking fourth in the world by biodiversity. In 2015 it was the 9th most visited country in the world, Mexico is a member of the United Nations, the World Trade Organization, the G8+5, the G20, the Uniting for Consensus and the Pacific Alliance. Mēxihco is the Nahuatl term for the heartland of the Aztec Empire, namely, the Valley of Mexico, and its people, the Mexica and this became the future State of Mexico as a division of New Spain prior to independence. It is generally considered to be a toponym for the valley became the primary ethnonym for the Aztec Triple Alliance as a result. After New Spain won independence from Spain, representatives decided to name the new country after its capital and this was founded in 1524 on top of the ancient Mexica capital of Mexico-Tenochtitlan

Sistema Sac Actun
–
Sistema Sac Actun is an underwater cave system situated along the Caribbean coast of the Yucatán Peninsula with passages to the north and west of the village of Tulum. Exploration started from Gran Cenote 5 kilometers west of Tulum, the whole of the explored cave system lies within the Municipality of Tulum. In early 2007, the underwater cave Sistema Nohoch Nah Chich was connected into, Sistema Naranjal cave complex is also related. Sac Actun measures 230.8 kilometers and is surpassed by Sistema Ox Bel Ha at 256.7 kilometers. Since early 2007, these two caves frequently exchanged the title of the longest Quintana Roo Speleological Survey underwater cave system in the world, including connected dry caves and Sistema Dos Ojos makes Sistema Sac Actun with 319 kilometers the longest cave in Mexico and the second longest worldwide. At a depth of 57 meters the divers located the remains of a mastodon as well as at 43 meters a human skull that might be the oldest evidence of habitation in this area to date. Additional bones were located and the skeleton was identified as that of a teenaged female now referred to as Naia.

Limestone
–
Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate, about 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes, most cave systems are through limestone bedrock. The first geologist to distinguish limestone from dolomite was Belsazar Hacquet in 1778, like most other sedimentary rocks, most limestone is composed of grains. Most grains in limestone are skeletal fragments of organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts and these organisms secrete shells made of aragonite or calcite, and leave these shells behind when they die. Limestone often contains variable amounts of silica in the form of chert or siliceous skeletal fragment, some limestones do not consist of grains at all, and are formed completely by the chemical precipitation of calcite or aragonite, i. e. travertine. Secondary calcite may be deposited by supersaturated meteoric waters and this produces speleothems, such as stalagmites and stalactites. Another form taken by calcite is oolitic limestone, which can be recognized by its granular appearance, the primary source of the calcite in limestone is most commonly marine organisms. Some of these organisms can construct mounds of rock known as reefs, below about 3,000 meters, water pressure and temperature conditions cause the dissolution of calcite to increase nonlinearly, so limestone typically does not form in deeper waters. Limestones may also form in lacustrine and evaporite depositional environments, calcite can be dissolved or precipitated by groundwater, depending on several factors, including the water temperature, pH, and dissolved ion concentrations. Calcite exhibits a characteristic called retrograde solubility, in which it becomes less soluble in water as the temperature increases. Impurities will cause limestones to exhibit different colors, especially with weathered surfaces, Limestone may be crystalline, clastic, granular, or massive, depending on the method of formation. Crystals of calcite, quartz, dolomite or barite may line small cavities in the rock, when conditions are right for precipitation, calcite forms mineral coatings that cement the existing rock grains together, or it can fill fractures. Travertine is a banded, compact variety of limestone formed along streams, particularly there are waterfalls. Calcium carbonate is deposited where evaporation of the leaves a solution supersaturated with the chemical constituents of calcite. Tufa, a porous or cellular variety of travertine, is found near waterfalls, coquina is a poorly consolidated limestone composed of pieces of coral or shells. During regional metamorphism that occurs during the building process, limestone recrystallizes into marble

Stratum
–
In geology and related fields, a stratum is a layer of sedimentary rock or soil with internally consistent characteristics that distinguish it from other layers. The stratum is the unit in a stratigraphic column and forms the basis of the study of stratigraphy. Each layer is one of a number of parallel layers that lie one upon another. They may extend over hundreds of thousands of kilometers of the Earths surface. Strata are typically seen as bands of different colored or differently structured material exposed in cliffs, road cuts, quarries, individual bands may vary in thickness from a few millimeters to a kilometer or more. Each band represents a mode of deposition, river silt, beach sand, coal swamp, sand dune, lava bed. Geologists study rock strata and categorize them by the material of beds, each distinct layer is typically assigned to the name of sheet, usually based on a town, river, mountain, or region where the formation is exposed and available for study. For example, the Burgess Shale is an exposure of dark, occasionally fossiliferous. Slight distinctions in material in a formation may be described as members, formations are collected into groups while groups may be collected into supergroups.

Sandstone
–
Sandstone is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz or feldspar because these are the most common minerals in the Earths crust, like sand, sandstone may be any color, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, quartz-bearing sandstone is converted into quartzite through heating and pressure, usually related to tectonic compression within orogenic belts. They are formed from cemented grains that may either be fragments of a rock or be mono-minerallic crystals. The cements binding these grains together are typically calcite, clays, grain sizes in sands are defined within the range of 0.0625 mm to 2 mm. The formation of sandstone involves two principal stages, first, a layer or layers of sand accumulates as the result of sedimentation, either from water or from air. Typically, sedimentation occurs by the settling out from suspension. The most common cementing materials are silica and calcium carbonate, which are derived either from dissolution or from alteration of the sand after it was buried. Colours will usually be tan or yellow, a predominant additional colourant in the southwestern United States is iron oxide, which imparts reddish tints ranging from pink to dark red, with additional manganese imparting a purplish hue. Red sandstones are seen in the Southwest and West of Britain, as well as central Europe. The regularity of the latter favours use as a source for masonry, either as a building material or as a facing stone. These physical properties allow the grains to survive multiple recycling events. Quartz grains evolve from rock, which are felsic in origin. Feldspathic framework grains are commonly the second most abundant mineral in sandstones, Feldspar can be divided into two smaller subdivisions, alkali feldspars and plagioclase feldspars. The different types of feldspar can be distinguished under a petrographic microscope, below is a description of the different types of feldspar. Alkali feldspar is a group of minerals in which the composition of the mineral can range from KAlSi3O8 to NaAlSi3O8. Plagioclase feldspar is a group of solid solution minerals that range in composition from NaAlSi3O8 to CaAl2Si2O8. Lithic framework grains are pieces of ancient source rock that have yet to weather away to individual mineral grains, accessory minerals are all other mineral grains in a sandstone, commonly these minerals make up just a small percentage of the grains in a sandstone
21.
Karst
–
Karst topography is a landscape formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves and it has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes, the English word karst was borrowed from German Karst in the late 19th century. The German word came into use before the 19th century, according to the prevalent interpretation, the term is derived from the German name for the Karst region, a limestone plateau above the city of Trieste in the northern Adriatic. Scholars disagree, however, on whether the German word was borrowed from Slovene, the Slovene common noun kras was first attested in the 18th century, and the adjective form kraški in the 16th century. The Slovene words arose through metathesis from the reconstructed form *korsъ, ultimately, the word is of Mediterranean origin, believed to derive from some Romanized Illyrian base. It has been suggested that the word may derive from the Proto-Indo-European root karra- rock, the name may also be connected to the oronym Karsádios oros cited by Ptolemy, and perhaps also to Latin Carusardius. The development of karst occurs whenever acidic water starts to break down the surface of bedrock near its cracks, as the bedrock continues to degrade, its cracks tend to get bigger. As time goes on, these fractures will become wider, if this underground drainage system does form, it will speed up the development of karst formations there because more water will be able to flow through the region, giving it more erosive power. The carbonic acid that causes karstic features is formed as rain passes through the atmosphere picking up carbon dioxide, once the rain reaches the ground, it may pass through soil that can provide much more CO2 to form a weak carbonic acid solution, which dissolves calcium carbonate. The oxidation of sulfides leading to the formation of acid can also be one of the corrosion factors in karst formation. As oxygen -rich surface waters seep into deep anoxic karst systems, they bring oxygen, sulfuric acid then reacts with calcium carbonate, causing increased erosion within the limestone formation. This chain of reactions is, This reaction chain forms gypsum, the karstification of a landscape may result in a variety of large- or small-scale features both on the surface and beneath. On exposed surfaces, small features may include solution flutes, runnels, limestone pavement, medium-sized surface features may include sinkholes or cenotes, vertical shafts, foibe, disappearing streams, and reappearing springs. Large-scale features may include limestone pavements, poljes, and karst valleys, mature karst landscapes, where more bedrock has been removed than remains, may result in karst towers, or haystack/eggbox landscapes. Beneath the surface, complex underground systems and extensive caves. Some of the most dramatic of these formations can be seen in Thailands Phangnga Bay, calcium carbonate dissolved into water may precipitate out where the water discharges some of its dissolved carbon dioxide. Rivers which emerge from springs may produce tufa terraces, consisting of layers of calcite deposited over extended periods of time, in caves, a variety of features collectively called speleothems are formed by deposition of calcium carbonate and other dissolved minerals
22.
Caprock
–
Caprock or cap rock is a harder or more resistant rock type overlying a weaker or less resistant rock type. Common types of caprock are sandstone and mafic rock types, in processes such as scarp retreat, the caprock controls the rate of erosion of the scarp. As the softer rock is cut away, periodically the caprock shears off, Caprock is also found on the top of mesa formations. The Niagara Escarpment, over which Niagara Falls flows, is an example of a scarp or escarpment, at Niagara Falls, the caprock is the riverbed above the falls, and is what prevents the river from eroding the face of the falls very quickly. In the photo, the thin layer in the foreground where water is not yet running, is the caprock. The Niagara caprock is made of dolomitic limestone, an analogy of caprock could be the outer crust on a cake that is a bit harder than the underlying layer. In the petroleum industry, caprock is any nonpermeable formation that may trap oil, gas or water and this caprock or trap can create a reservoir of oil, gas or water beneath it and is a primary target for the petroleum industry. The tops of salt domes such as in the Gulf of Mexico dissolve in a characteristic manner, the halite is removed first, leaving behind gypsum and anhydrite. The anhydrite and gypsum react with material to form calcite. The classic Murray 1966 paper describes the sequence as sediments-calcite-gypsum-anhydrite-salt.

Caving
–
Caving — also traditionally known as spelunking in the United States and Canada and potholing in the United Kingdom and Ireland — is the recreational pastime of exploring wild cave systems. In contrast, speleology is the study of caves and the cave environment. Cave diving is a distinct, and more hazardous, sub-speciality undertaken by a minority of technically proficient cavers. Sometimes categorized as a sport, it is not commonly considered as such by long-time enthusiasts. Many caving skills overlap with those involved in canyoning, mine, Caving is often undertaken for the enjoyment of the outdoor activity or for physical exercise, as well as original exploration, similar to mountaineering or diving. Physical or biological science is also an important goal for some cavers, virgin cave systems comprise some of the last unexplored regions on Earth and much effort is put into trying to locate, enter and survey them. In well-explored regions, the most accessible caves have already been explored, Caving, in certain areas, has also been utilized as a form of eco and adventure tourism. Tour companies have established a leading and guiding tours into. Depending on the type of cave and the type of tour, in many areas, there are tours led through lava tubes by a guiding service. Some however consider the assistance cavers give each other as a team sport activity. Too much emphasis on the labeling of caving as a sport can narrow the goals of caving as a whole, Caving often puts the needs and welfare of a cave before those of the active participants. Clay Perry, an American caver of the 1940s, wrote about a group of men and this group referred to themselves as spelunkers, a term derived from the Latin spēlunca cave, cavern, den, itself from the Greek σπῆλυγξ spēlynks cave. This is regarded as the first use of the word in the Americas, throughout the 1950s, spelunking was the general term used for exploring caves in US English. It was used freely, without any positive or negative connotations, in the 1960s, the terms spelunking and spelunker began to be considered déclassé among experienced enthusiasts. This sentiment is exemplified by bumper stickers and T-shirts displayed by some cavers, Cavers rescue spelunkers, nevertheless, outside the caving community, spelunking and spelunkers predominately remain neutral terms referring to the practice and practitioners, without any respect to skill level. Potholing refers to the act of exploring potholes, a word originating in the north of England for predominantly vertical caves, the base term caving comes from the Latin cavea or caverna, meaning simply, a cave. He developed his own based on ropes and metallic ladders. Martel visited Kentucky and notably Mammoth Cave National Park in October 1912, robert de Joly, Guy de Lavaur and Norbert Casteret were prominent figures of that time, surveying mostly caves in Southwest France

Stratigraphy
–
Stratigraphy is a branch of geology which studies rock layers and layering. It is primarily used in the study of sedimentary and layered volcanic rocks, stratigraphy has two related subfields, lithologic stratigraphy or lithostratigraphy, and biologic stratigraphy or biostratigraphy. The first practical application of stratigraphy was by William Smith in the 1790s. Another influential application of stratigraphy in the early 19th century was a study by Georges Cuvier, variation in rock units, most obviously displayed as visible layering, is due to physical contrasts in rock type. This variation can occur vertically as layering, or laterally, and these variations provide a lithostratigraphy or lithologic stratigraphy of the rock unit. Key concepts in stratigraphy involve understanding how certain geometric relationships between rock layers arise and what these geometries imply about their original depositional environment. The basic concept in stratigraphy, called the law of superposition, states, in a stratigraphic sequence. Chemostratigraphy studies the changes in the proportions of trace elements and isotopes within. Carbon and oxygen isotope ratios vary with time, and researchers can use those to map subtle changes that occurred in the paleoenvironment and this has led to the specialized field of isotopic stratigraphy. Biostratigraphy or paleontologic stratigraphy is based on evidence in the rock layers. Strata from widespread locations containing the fossil fauna and flora are said to be correlatable in time. Biologic stratigraphy was based on William Smiths principle of succession, which predated. It provides strong evidence for the formation and extinction of species, the geologic time scale was developed during the 19th century, based on the evidence of biologic stratigraphy and faunal succession. One important development is the Vail curve, which attempts to define a global historical sea-level curve according to inferences from worldwide stratigraphic patterns, stratigraphy is also commonly used to delineate the nature and extent of hydrocarbon-bearing reservoir rocks, seals, and traps of petroleum geology. Chronostratigraphy is the branch of stratigraphy that places an absolute age, a gap or missing strata in the geological record of an area is called a stratigraphic hiatus. This may be the result of a halt in the deposition of sediment, alternatively, the gap may be due to removal by erosion, in which case it may be called a stratigraphic vacuity. It is called a hiatus because deposition was on hold for a period of time, a physical gap may represent both a period of non-deposition and a period of erosion. A geologic fault may cause the appearance of a hiatus, magnetostratigraphy is a chronostratigraphic technique used to date sedimentary and volcanic sequences
25.
Stalactite
–
A stalactite is a type of formation that hangs from the ceiling of caves, hot springs, or manmade structures such as bridges and mines. Any material which is soluble, can be deposited as a colloid, or is in suspension, or is capable of being melted, Stalactites may be composed of amberat, lava, minerals, mud, peat, pitch, sand, and sinter. A stalactite is not necessarily a speleothem, though speleothems are the most common form of stalactite because of the abundance of limestone caves, the corresponding formation on the floor of the cave is known as a stalagmite. The most common stalactites are speleothems, which occur in limestone caves and they form through deposition of calcium carbonate and other minerals, which is precipitated from mineralized water solutions. Limestone is the form of calcium carbonate rock which is dissolved by water that contains carbon dioxide. When the solution comes into contact with air the chemical reaction that created it is reversed, the reversed reaction is, Ca 2 → CaCO3 + H 2O + CO2 An average growth rate is 0.13 mm a year. The quickest growing stalactites are formed by a constant supply of slow dripping water rich in calcium carbonate and carbon dioxide. The drip rate must be enough to allow the CO2 to degas from the solution into the cave atmosphere. Too fast a drip rate and the solution, still carrying most of the CaCO3, falls to the floor where degassing occurs. All limestone stalactites begin with a single drop of water. When the drop falls, it deposits the thinnest ring of calcite, each subsequent drop that forms and falls deposits another calcite ring. Eventually, these form a very narrow, hollow tube commonly known as a soda straw stalactite. Soda straws can grow long, but are very fragile. If they become plugged by debris, water flowing over the outside, depositing more calcite. The same water drops that fall from the tip of a stalactite deposit more calcite on the floor below, unlike stalactites, stalagmites never start out as hollow soda straws. Given enough time, these formations can meet and fuse to create pillars of calcium carbonate known as a column, another type of stalactite is formed in lava tubes while lava is still active inside. The mechanism of formation is similar to that of limestone stalactites, a key difference with lava stalactites is that once the lava has ceased flowing, so too will the stalactites cease to grow. This means that if the stalactite were to be broken it would never grow back, the generic term lavacicle has been applied to lava stalactites and stalagmites indiscriminately and evolved from the word icicle
26.
Stalagmite
–
A stalagmite is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites may be composed of amberat, lava, minerals, mud, peat, pitch, sand, the corresponding formation hanging down from the ceiling of a cave is a stalactite. Mnemonics have been developed for which word refers to type of formation, one is that stalactite has a C for ceiling. The most common stalagmites are speleothems, which form in limestone caves. This stalagmite formation occurs only under certain pH conditions within the underground cavern and they form through deposition of calcium carbonate and other minerals, which is precipitated from mineralized water solutions. Limestone is the form of calcium carbonate rock, which is dissolved by water that contains carbon dioxide. If stalactites – the ceiling formations – grow long enough to connect with stalagmites on the floor, oils and dirt from human contact can also stain the formation and change its color permanently. Another type of stalagmite is formed in lava tubes while lava is still active inside, the mechanism of formation is similar to that of limestone stalagmites. A key difference with lava stalagmites is that once the lava has ceased flowing and this means if the stalagmite were to be broken it would never grow back. Stalagmites in lava tubes are rarer than their stalactite counterparts because during formation the dripping material falls onto still-moving lava floors that absorb or carry the material away, the generic term lavacicle has been applied to lava stalactites and stalagmites indiscriminately, and evolved from the word icicle. A common stalagmite found seasonally or year round in many caves is the ice stalagmite, commonly referred to as icicles, water seepage from the surface will penetrate into a cave and if temperatures are below freezing temperature, the water will collect on the floor into stalagmites. Deposition may also directly from the freezing of water vapor. Similar to lava stalagmites, ice stalagmites form very quickly within hours or days, unlike lava stalagmites however, they may grow back as long as water and temperatures are suitable. Ice stalagmites are more common than their stalactite counterparts because warmer air rises to the ceilings of caves, ice stalactites may also form corresponding stalagmites below them, and given time, may grow together to form an ice column. Stalactites and stalagmites can also form on concrete ceilings and floors, calcium carbonate deposition as a stalagmite occurs when the solution carries the calcium laden leachate solution to the ground under the concrete structure. Carbon dioxide is absorbed into the alkaline solution, which facilitates the chemical reactions to deposit calcium carbonate as a stalagmite. These stalagmites rarely grow taller than a few centimetres, secondary deposits, which create stalagmites, stalactites, flowstone etc, outside the natural cave environment, are referred to as “calthemites”. These concrete derived secondary deposits can’t be referred to as “speleothems” due to the definition of the word, the largest known stalagmite in the world exceeds 70 metres in height and is located in Sơn Đoòng Cave, Vietnam
27.
Sinkhole
–
A sinkhole, also known as a cenote, sink, sink-hole, shakehole, swallet, swallow hole, or doline, is a depression or hole in the ground caused by some form of collapse of the surface layer. Most are caused by karst processes—for example, the dissolution of carbonate rocks or suffosion processes. Sinkholes vary in size from 1 to 600 m both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms, sinkholes may form gradually or suddenly, and are found worldwide. Sinkholes may capture surface drainage from running or standing water, but may form in high. Sinkholes that capture drainage can hold it in limestone caves. These caves may drain into tributaries of larger rivers, the formation of sinkholes involves natural processes of erosion or gradual removal of slightly soluble bedrock by percolating water, the collapse of a cave roof, or a lowering of the water table. Sinkholes often form through the process of suffosion, for example, groundwater may dissolve the carbonate cement holding the sandstone particles together and then carry away the lax particles, gradually forming a void. Occasionally a sinkhole may exhibit a visible opening into a cave below, sinkholes also occur in sandstone and quartzite terrains. As the rock dissolves, spaces and caverns develop underground and these sinkholes can be dramatic, because the surface land usually stays intact until there is not enough support. Then, a collapse of the land surface can occur. Sinkholes also form from human activity, such as the collapse of abandoned mines and salt cavern storage in salt domes in places like Louisiana, Mississippi, more commonly, sinkholes occur in urban areas due to water main breaks or sewer collapses when old pipes give way. They can also occur from the overpumping and extraction of groundwater, sinkholes can also form when natural water-drainage patterns are changed and new water-diversion systems are developed. Sinkholes tend to occur in karst landscapes, karst landscapes can have up to thousands of sinkholes within a small area, giving the landscape a pock-marked appearance. These sinkholes drain all the water, so there are only subterranean rivers in these areas, examples of karst landscapes with a plethora of massive sinkholes include Khammouan Mountains and Mamo Plateau. The largest known sinkholes formed in sandstone are Sima Humboldt and Sima Martel in Venezuela, some sinkholes form in thick layers of homogenous limestone. On the contact of limestone and insoluble rock below it, powerful underground rivers may form, in such conditions, the largest known sinkholes of the world have formed, like the 662-metre deep Xiaozhai Tiankeng, giant sótanos in Querétaro and San Luis Potosí states in Mexico and others. The state of Florida in the United States is known for having frequent sinkhole collapses, the Murge area in southern Italy also has numerous sinkholes. Sinkholes can be formed in retention ponds from large amounts of rain, an analysis of a case of sinkhole formation under a retention pond due to a large amount of rain can be seen in a sinkhole collapse study

Endangered species
–
An endangered species is a species which has been categorized as likely to become extinct. In 2012, the IUCN Red List featured 3079 animal and 2655 plant species as endangered worldwide, the figures for 1998 were, respectively,1102 and 1197. Many nations have laws that protect conservation-reliant species, for example, population numbers, trends and species conservation status can be found in the lists of organisms by population. The conservation status of a species indicates the likelihood that it will become extinct, the IUCN Red List of Threatened Species is the best-known worldwide conservation status listing and ranking system. Over 40% of the species are estimated to be at risk of extinction. Internationally,199 countries have signed an accord to create Biodiversity Action Plans that will protect endangered, in the United States, such plans are usually called Species Recovery Plans. Those species of Near Threatened and Least Concern status have been assessed and found to have relatively robust and healthy populations, though these may be in decline. The IUCN categories, with examples of animals classified by them, include, Extinct Extinct in the wild Captive individuals survive, critically endangered Faces an extremely high risk of extinction in the immediate future. Endangered Faces a high risk of extinction in the near future, vulnerable Faces a high risk of endangerment in the medium term. Near-threatened May be considered threatened in the near future, Least concern No immediate threat to species survival.

E) Quantitative analysis showing the probability of extinction in the wild is at least 20% within 20 years or five generations, there is data from the United States that shows a correlation between human populations and threatened and endangered species. Under the Endangered Species Act in the United States, species may be listed as endangered or threatened, the Salt Creek tiger beetle is an example of an endangered subspecies protected under the ESA. Some endangered species laws are controversial, also lobbying from hunters and various industries like the petroleum industry, construction industry, and logging, has been an obstacle in establishing endangered species laws. The Bush administration lifted a policy that required federal officials to consult an expert before taking actions that could damage endangered species. Under the Obama administration, this policy has been reinstated, being listed as an endangered species can have negative effect since it could make a species more desirable for collectors and poachers. This effect is potentially reducible, such as in China where commercially farmed turtles may be reducing some of the pressure to poach endangered species. Another problem with the species is its effect of inciting the use of the shoot, shovel

Shrimp
–
The term shrimp is used to refer to some decapod crustaceans, although the exact animals covered can vary. Used broadly, it may cover any of the groups with elongated bodies, in some fields, however, the term is used more narrowly, and may be restricted to Caridea, to smaller species of either group, or to only the marine species. Under the broader definition, shrimp may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long narrow muscular tails, long whiskers, any small crustacean which resembles a shrimp tends to be called one. They swim forward by paddling with swimmerets on the underside of their abdomens, crabs and lobsters have strong walking legs, whereas shrimp have thin fragile legs which they use primarily for perching. There are thousands of species adapted to a range of habitats. They can be found feeding near the seafloor on most coasts and estuaries, as well as in rivers, to escape predators, some species flip off the seafloor and dive into the sediment. They usually live from one to seven years, Shrimp are often solitary, though they can form large schools during the spawning season. They play important roles in the chain and are an important food source for larger animals ranging from fish to whales. The muscular tails of many shrimp are edible to humans, and they are widely caught, commercial shrimp species support an industry worth 50 billion dollars a year, and in 2010 the total commercial production of shrimp was nearly 7 million tonnes. Shrimp farming became prevalent during the 1980s, particularly in China. There are significant issues with excessive bycatch when shrimp are captured in the wild, many shrimp species are small as the term shrimp suggests, about 2 cm long, but some shrimp exceed 25 cm. Larger shrimp are likely to be targeted commercially, and are often referred to as prawns. Shrimp are swimming crustaceans with long narrow muscular abdomens and long antennae, unlike crabs and lobsters, shrimp have well developed pleopods and slender walking legs, they are more adapted for swimming than walking. Historically, it was the distinction between walking and swimming that formed the primary taxonomic division into the former suborders Natantia and Reptantia, members of the Natantia were adapted for swimming while the Reptantia were adapted for crawling or walking. Some other groups also have names that include the word shrimp. The following description refers mainly to the anatomy of the common European shrimp, Crangon crangon. The body of the shrimp is divided into two parts, the head and thorax which are fused together to form the cephalothorax. The shell which protects the cephlathorax is harder and thicker than the shell elsewhere on the shrimp, the carapace typically surrounds the gills, through which water is pumped by the action of the mouthparts

Kentucky Route 70
–
Kentucky Route 70 is a long east-east state highway that originates at a junction with U. S. Route 60 in Smithland in Livingston County, just east of the Ohio River. Kentucky Route 70 begins in the Livingston County seat of Smithland, Kentucky and it travels eastward to a junction with KY866, and reaches a dead end at Tiline, along the Cumberland River. KY70 does not connect from there to Dycusburg, not since the service at that point was discontinued in 1951. KY70 returns to life at Dycusburg, on the Crittenden County side of the river, KY295 ends at that same point. KY70 moves on to join US Route 641 and Kentucky Route 91 in southern Crittenden County, KY70 and 91 departs from US641, and then the two state routes split not too long after. Highway 91 goes southeast for Princeton, while KY70 continues due east to go through mainly rural sections of northern Caldwell County, KY70 crosses the Tradewater River into Hopkins County. It intersects }KY109 at Beulah, and then reaches Madisonville and it gets co-signed with U. S. Route 41 in downtown Madisonville before breaking off and then traverses the Exit 114 interchange of Interstate 69 on the east side. It intersects KY85 just east of town before KY70 enters Muhlenberg County, in Central City, US431 and KY70 both meet US Route 62, and then traverse the exit 58 interchange of the Wendell H. Ford Western Kentucky Parkway. That interchange was a toll booth site until the 1987 discontinuation of the WK Parkways toll plazas. The concurrently running US431 and KY70 continues southeastward from Central City through the intersection of KY176 in Drakesboro, much of US 431s concurrency with KY70 is designated as part of a Kentucky Scenic Byway. KY70 breaks off from US431 at that point south of Drakesboro, steam from the Tennessee Valley Authoritys Paradise Coal-firing plant can be seen from the highway between Drakesboro and Rochester. In Butler County, Kentucky Route 70 intersects KY369 while going through Rochester and it then intersects Kentucky Route 106 not too far southeast of there, and would then go on to the communities of South Hill and Dunbar. Not too far east of Dunbar, KY70 intersects KY1468, the route intersects the Exit 29 interchange of the Natcher Parkway. That intersection opened during the 1999-2000 fiscal year, between the Natcher Parkway and US 231/KY79, KY70 is known as Veterans Way and runs concurrently with US231 Truck and KY79 Truck. KY70 runs concurrently with U. S. Route 231 and Kentucky Route 79 from Morgantown, in Aberdeen, KY70 actually departs US231 a little bit after KY79 does. KY70 then intersects KY79 for a time, continuing east from Aberdeen through Jetson, and then Roundhill. After the intersection with KY185, KY70 immediately enters Edmonson County, KY70 then rolls onward towards the communities of Huff and Windyville. It then meets KY259, and then KY70 and 259 run concurrently to cross the Green River at Brownsville and this is KY 70s second crossing of the Green River

Kentucky Route 255
–
Kentucky Route 255 is a south-north highway located in south central Kentucky. It provides access to Interstate 65 and Mammoth Cave National park to residents of southern Barren County, KY255 begins at a junction with KY252 in Barren County, near the Rocky Hill community. The route is narrow and considerably curvy until coming to a junction with KY12973.3 miles later. After this junction, the route straightens somewhat, proceeding north for another 3.1 miles before coming to an intersection with the cojoined US 68/KY80 in the Bon Ayr community. KY255 widens somewhat past this point, continuing on for another mile before bridging the Cumberland Parkway via way of an overpass, the route then proceeds north for 0.8 miles before coming to an intersection with KY1339. KY255 then continues north for 2.5 miles before being carried onto a bridge over a CSX railroad track, KY 255s concurrent run with US 31W lasts 0.16 miles, where KY255 turns left onto Mammoth Cave Parkway. Its original concurrency with US 31W lasted for 0.2 miles, KY255 branches north, going 0.4 miles before intersecting with Interstate 65 at its Exit 48 interchange. After this intersection, KY255 continues in a path and enters Mammoth Cave National Park. At that point KY255 joins KY70 by making a right turn and this concurrency lasts for 1.666 miles before reaching an intersection where KY255 turns left, while KY70 turns right to head for Cave City. This was KY 255s original northern terminus from the 1930s until sometime in the mid 1970s, KY 255s current northern terminus is located near the Sand Cave Trail at another entry into the Mammoth Cave National Park. That point marks the end of state maintenance, the road itself, however continues into the park, and ends at another intersection with the Mammoth Cave Parkway just south of the parks visitor center. This road was part of the original KY70 alignment within the park until it was rerouted to its current in-park alignment in the 1970s, the state route was established during the 1930s. It originally ran from Park City, following the Barren-Edmonson County line, ky 255 was also extended onto the old KY70 alignment from the current KY255/70 split in Barren County to the southeast boundary of the Mammoth Cave park. The ruins of Bells Tavern are located alongside the original KY255 alignment near the railroad tracks, built in 1830, it was a favorite stop of wealthy patrons before it burned in 1860. A roadside marker marks the location of the tavern and details some of its history, diamond Caverns, the second oldest cave tour operation in the United States, is located just off of KY255, just north of its intersection with I-65. A roadside marker gives a history of the site

Native Americans in the United States
–
In the United States, Native Americans are people descended from the Pre-Columbian indigenous population of the land within the countrys modern boundaries. These peoples were composed of distinct tribes, bands, and ethnic groups. Most Native American groups had historically preserved their histories by oral traditions and artwork, at the time of first contact, the indigenous cultures were quite different from those of the proto-industrial and mostly Christian immigrants. Some of the Northeastern and Southwestern cultures in particular were matrilineal, the majority of Indigenous American tribes maintained their hunting grounds and agricultural lands for use of the entire tribe. Europeans at that time had patriarchal cultures and had developed concepts of property rights with respect to land that were extremely different. Assimilation became a consistent policy through American administrations, during the 19th century, the ideology of manifest destiny became integral to the American nationalist movement. Expansion of European-American populations to the west after the American Revolution resulted in increasing pressure on Native American lands and this resulted in the ethnic cleansing of many tribes, with the brutal, forced marches coming to be known as The Trail of Tears. As American expansion reached into the West, settler and miner migrants came into increasing conflict with the Great Basin, Great Plains and these were complex nomadic cultures based on horse culture and seasonal bison hunting. Over time, the United States forced a series of treaties and land cessions by the tribes, in 1924, Native Americans who were not already U. S. citizens were granted citizenship by Congress. Contemporary Native Americans have a relationship with the United States because they may be members of nations, tribes. The terms used to refer to Native Americans have at times been controversial, by comparison, the indigenous peoples of Canada are generally known as First Nations. It is not definitively known how or when the Native Americans first settled the Americas and these early inhabitants, called Paleoamericans, soon diversified into many hundreds of culturally distinct nations and tribes. The archaeological periods used are the classifications of archaeological periods and cultures established in Gordon Willey and Philip Phillips 1958 book Method and they divided the archaeological record in the Americas into five phases, see Archaeology of the Americas. The Clovis culture, a hunting culture, is primarily identified by use of fluted spear points. Artifacts from this culture were first excavated in 1932 near Clovis, the Clovis culture ranged over much of North America and also appeared in South America. The culture is identified by the distinctive Clovis point, a flaked flint spear-point with a notched flute, dating of Clovis materials has been by association with animal bones and by the use of carbon dating methods. Recent reexaminations of Clovis materials using improved carbon-dating methods produced results of 11,050 and 10,800 radiocarbon years B. P, other tribes have stories that recount migrations across long tracts of land and a great river, believed to be the Mississippi River. Genetic and linguistic data connect the people of this continent with ancient northeast Asians

Mummy
–
Some authorities restrict the use of the term to bodies deliberately embalmed with chemicals, but the use of the word to cover accidentally desiccated bodies goes back to at least 1615 CE. Mummies of humans and other animals have found on every continent. Over one million animal mummies have been found in Egypt, many of which are cats, in addition to the well-known mummies of ancient Egypt, deliberate mummification was a feature of several ancient cultures in areas of America and Asia with very dry climates. The Spirit Cave mummies of Fallon, Nevada in North America were accurately dated at more than 9,400 years old. Before this discovery, the oldest known deliberate mummy was a child, one of the Chinchorro mummies found in the Camarones Valley, Chile, which dates around 5050 BCE. The oldest known naturally mummified corpse is a severed head dated as 6,000 years old. These substances were defined as mummia, the OED defines a mummy as the body of a human being or animal embalmed as a preparation for burial, citing sources from 1615 CE onward. However, Chambers Cyclopædia and the Victorian zoologist Francis Trevelyan Buckland define a mummy as follows, also applied to the frozen carcase of an animal imbedded in prehistoric snow. Wasps of the genus Aleiodes are known as mummy wasps because they wrap their prey as mummies. While interest in the study of mummies dates as far back as Ptolemaic Greece, prior to this, many rediscovered mummies were sold as curiosities or for use in pseudoscientific novelties such as mummia. The first modern scientific examinations of mummies began in 1901, conducted by professors at the English-language Government School of Medicine in Cairo, Egypt. The first X-ray of a mummy came in 1903, when professors Grafton Elliot Smith, British chemist Alfred Lucas applied chemical analyses to Egyptian mummies during this same period, which returned many results about the types of substances used in embalming. Lucas also made significant contributions to the analysis of Tutankhamun in 1922, pathological study of mummies saw varying levels of popularity throughout the 20th century. In 1992, the First World Congress on Mummy Studies was held in Puerto de la Cruz on Tenerife in the Canary Islands, more than 300 scientists attended the Congress to share nearly 100 years of collected data on mummies. This was not possible prior to the Congress due to the unique, in more recent years, CT scanning has become an invaluable tool in the study of mummification by allowing researchers to digitally unwrap mummies without risking damage to the body. The level of detail in such scans is so intricate that small linens used in areas such as the nostrils can be digitally reconstructed in 3-D. Such modelling has been utilized to perform autopsies on mummies to determine cause of death and lifestyle. Mummies are typically divided into one of two categories, anthropogenic or spontaneous

Pre-Columbian era
–
For this reason the alternative terms of Precontact Americas, Pre-Colonial Americas or Prehistoric Americas are also in use. In areas of Latin America the term used is Pre-Hispanic. Other civilizations were contemporary with the period and were described in European historical accounts of the time. A few, such as the Maya civilization, had their own written records, because many Christian Europeans of the time viewed such texts as heretical, men like Diego de Landa destroyed many texts in pyres, even while seeking to preserve native histories. Only a few documents have survived in their original languages, while others were transcribed or dictated into Spanish, giving modern historians glimpses of ancient culture. Indigenous American cultures continue to evolve after the pre-Columbian era, many of these peoples and their descendants continue traditional practices, while evolving and adapting new cultural practices and technologies into their lives. Now, the study of pre-Columbian cultures is most often based on scientific. Asian nomads are thought to have entered the Americas via the Bering Land Bridge, now the Bering Strait, genetic evidence found in Amerindians maternally inherited mitochondrial DNA supports the theory of multiple genetic populations migrating from Asia. Over the course of millennia, Paleo-Indians spread throughout North and South America, exactly when the first group of people migrated into the Americas is the subject of much debate. One of the earliest identifiable cultures was the Clovis culture, with sites dating from some 13,000 years ago, however, older sites dating back to 20,000 years ago have been claimed. Some genetic studies estimate the colonization of the Americas dates from between 40,000 and 13,000 years ago, the chronology of migration models is currently divided into two general approaches. The first is the short chronology theory with the first movement beyond Alaska into the New World occurring no earlier than 14, 000–17,000 years ago, followed by successive waves of immigrants. The second belief is the long chronology theory, which proposes that the first group of people entered the hemisphere at an earlier date, possibly 50. In that case, the Eskimo peoples would have arrived separately and at a later date, probably no more than 2,000 years ago. The North American climate was unstable as the ice age receded and it finally stabilized by about 10,000 years ago, climatic conditions were then very similar to todays. Within this timeframe, roughly pertaining to the Archaic Period, numerous archaeological cultures have been identified, the unstable climate led to widespread migration, with early Paleo-Indians soon spreading throughout the Americas, diversifying into many hundreds of culturally distinct tribes. The paleo-indians were hunter-gatherers, likely characterized by small, mobile bands consisting of approximately 20 to 50 members of an extended family and these groups moved from place to place as preferred resources were depleted and new supplies were sought. During much of the Paleo-Indian period, bands are thought to have subsisted primarily through hunting now-extinct giant land animals such as mastodon, Paleo-Indian groups carried a variety of tools

Washington University in St. Louis
–
Washington University in St. Louis is a private research university located in St. Louis, Missouri, United States. Founded in 1853, and named after George Washington, the university has students and faculty from all 50 U. S. states, twenty-five Nobel laureates have been affiliated with Washington University, nine having done the major part of their pioneering research at the university. Washington Universitys undergraduate program is ranked 19th by U. S. News & World Report, the university is ranked 23rd in the world in 2016 by the Academic Ranking of World Universities. Washington University is made up of seven graduate and undergraduate schools that encompass a range of academic fields. To prevent confusion over its location, the Board of Trustees added the phrase in St. Louis in 1976, Washington University was conceived by 17 St. Louis business, political, and religious leaders concerned by the lack of institutions of higher learning in the Midwest. Missouri State Senator Wayman Crow and Unitarian minister William Greenleaf Eliot, grandfather of the poet T. S. Eliot, the universitys first chancellor was Joseph Gibson Hoyt. Crow secured the university charter from the Missouri General Assembly in 1853, early on, Eliot solicited support from members of the local business community, including John OFallon, but Eliot failed to secure a permanent endowment. Washington University is unusual among major American universities in not having had a financial endowment. The institution had no backing of an organization, single wealthy patron. During the three following its inception, the university bore three different names. In 1854, the Board of Trustees changed the name to Washington Institute in honor of George Washington, naming the University after the nations first president, only seven years before the American Civil War and during a time of bitter national division, was no coincidence. During this time of conflict, Americans universally admired George Washington as the father of the United States, the Board of Trustees believed that the university should be a force of unity in a strongly divided Missouri. In 1856, the University amended its name to Washington University, although chartered as a university, for many years Washington University functioned primarily as a night school located on 17th Street and Washington Avenue in the heart of downtown St. Louis. Owing to limited resources, Washington University initially used public buildings. Classes began on October 22,1854, at the Benton School building, at first the university paid for the evening classes, but as their popularity grew, their funding was transferred to the St. Louis Public Schools. Eventually the board secured funds for the construction of Academic Hall, later the university divided into three departments, the Manual Training School, Smith Academy, and the Mary Institute. In 1867, the university opened the first private law school west of the Mississippi River. By 1882, Washington University had expanded to numerous departments, which were housed in buildings across St. Louis

St. Louis
–
St. Louis is an independent city and major U. S. port in the state of Missouri, built along the western bank of the Mississippi River, on the border with Illinois. Prior to European settlement, the area was a regional center of Native American Mississippian culture. The city of St. Louis was founded in 1764 by French fur traders Pierre Laclède and Auguste Chouteau, in 1764, following Frances defeat in the Seven Years War, the area was ceded to Spain and retroceded back to France in 1800. In 1803, the United States acquired the territory as part of the Louisiana Purchase, during the 19th century, St. Louis developed as a major port on the Mississippi River. In the 1870 Census, St. Louis was ranked as the 4th-largest city in the United States and it separated from St. Louis County in 1877, becoming an independent city and limiting its own political boundaries. In 1904, it hosted the Louisiana Purchase Exposition and the Summer Olympics, the economy of metro St. Louis relies on service, manufacturing, trade, transportation of goods, and tourism. This city has become known for its growing medical, pharmaceutical. St. Louis has 2 professional sports teams, the St. Louis Cardinals of Major League Baseball, the city is commonly identified with the 630-foot tall Gateway Arch in Downtown St. Louis. The area that would become St. Louis was a center of the Native American Mississippian culture and their major regional center was at Cahokia Mounds, active from 900 AD to 1500 AD. Due to numerous major earthworks within St. Louis boundaries, the city was nicknamed as the Mound City and these mounds were mostly demolished during the citys development. Historic Native American tribes in the area included the Siouan-speaking Osage people, whose territory extended west, European exploration of the area was first recorded in 1673, when French explorers Louis Jolliet and Jacques Marquette traveled through the Mississippi River valley. Five years later, La Salle claimed the region for France as part of La Louisiane. The earliest European settlements in the area were built in Illinois Country on the east side of the Mississippi River during the 1690s and early 1700s at Cahokia, Kaskaskia, migrants from the French villages on the opposite side of the Mississippi River founded Ste. In early 1764, after France lost the 7 Years War, Pierre Laclède, the early French families built the citys economy on the fur trade with the Osage, as well as with more distant tribes along the Missouri River. The Chouteau brothers gained a monopoly from Spain on the fur trade with Santa Fe, French colonists used African slaves as domestic servants and workers in the city. In 1780 during the American Revolutionary War, St. Louis was attacked by British forces, mostly Native American allies, the founding of St. Louis began in 1763. Pierre Laclede led an expedition to set up a fur-trading post farther up the Mississippi River, before then, Laclede had been a very successful merchant. For this reason, he and his trading partner Gilbert Antoine de St. Maxent were offered monopolies for six years of the fur trading in that area

Archaic period (North America)
–
The Archaic stage is characterized by subsistence economies supported through the exploitation of nuts, seeds, and shellfish. As its ending is defined by the adoption of sedentary farming and this classification system was first proposed by Gordon Willey and Philip Phillips in the widely accepted 1958 book Method and Theory in American Archaeology. In the organization of the system, the Archaic period followed the Lithic stage and is superseded by the Formative stage, the Lithic stage The Archaic stage The Formative stage The Classic stage The Post-Classic stage Numerous local variations have been identified within the cultural rankings. The period has been subdivided by region and then time, for instance, the Archaic Southwest tradition is subdivided into the Dieguito-Pinto, Oshara, Cochise and Chihuahua cultures. Such early mound sites as Frenchmans Bend and Hedgepeth were of time period. Watson Brake is now considered the oldest mound complex in the Americas, more than 100 sites have been identified as associated with the regional Poverty Point culture of the Late Archaic period, and it was part of a regional trading network across the Southeast. Across what is now the Southeastern United States, starting around 4000 BCE, people exploited wetland resources, middens developed along rivers, but there is limited evidence of Archaic peoples along coastlines prior to 3000 BCE. Archaic sites on the coast may have been inundated by rising sea levels, starting around 3000 BCE evidence of large-scale exploitation of oysters appears. During the period 3000 BCE to 1000 BCE shell rings, large shell middens more or less surrounding open centers, developed along the coast of the Southeastern United States. These shell rings are numerous in South Carolina and Georgia, but are found scattered around the Florida Peninsula. In some places, such as Horrs Island in Southwest Florida, four shell or sand mounds on Horrs Island have been dated to between 4,870 and 4,270 Before Present. The site which is considered to be one of the most significant centres of habitation and ceremonial burial in Canada, is located on the north side Rainy River in Northwestern Ontario. It became part of a trading network because of its strategic location at the centre of major North American waterways.

Woodland period
–
The term Woodland Period was introduced in the 1930s as a generic term for prehistoric sites falling between the Archaic hunter-gatherers and the agriculturalist Mississippian cultures. The Eastern Woodlands cultural region covers what is now eastern Canada south of the Subarctic region and this period is variously considered a developmental stage, a time period, a suite of technological adaptations or traits, and a family tree of cultures related to earlier Archaic cultures. Many Woodland peoples used spears and atlatls until the end of the period, the most cited technological distinction of this period was the widespread use of pottery, and the diversification of pottery forms, decorations, and manufacturing practices. Intensive agriculture characterizes the Mississippian period from ca, 1000-1400 CE and may have continued up to European contact, around 500 years ago. Eastern Woodlands lived in wigwams and longhouses, clay for pottery was typically tempered with grit or limestone. Pots were usually made in a conoidal or conical jars with rounded shoulders, slightly constricted necks, pots were coiled and paddled entirely by hand without the use of fast rotation such as a pottery wheel. Some were slipped or brushed with red ochre, pottery, agriculture, and permanent settlements have often been thought of the three defining characteristics of the Woodland period. Nevertheless, these sites were typical Archaic settlements, differing only in the use of basic ceramic technology. Most of these are evident in the Southeastern United States by 1000 BCE, in some areas, like South Carolina and coastal Georgia, Deptford culture pottery manufacture ceased after ca.700 CE. In coastal regions, many settlements were near the coast, often near salt marshes, people tended to settle along rivers and lakes in both coastal and interior regions for maximum access to food resources. Most groups relied heavily on white-tailed deer, but a variety of small and large mammals were hunted also, including beaver, raccoon. Shellfish formed an important part of the diet, attested to by numerous shell middens along the coast, seasonal foraging also characterized the strategies of many interior populations, with groups moving strategically among dense resource areas. Recently evidence has accumulated of a reliance of woodland peoples on cultivation in this period, at least in some localities. This is especially true for the middle period and perhaps beyond. C. Margaret Scarry states in the Woodland periods, people diversified their use of plant foods, increased their consumption of starchy foods. They did so, however, by cultivating starchy seeds rather than by gathering more acorns, smith and Yarnell refer to an indigenous crop complex as early as 3800 B. P. in parts of the region. The beginning of the Middle Woodland saw a shift of settlement to the Interior, as the Woodland period progressed, local and inter-regional trade of exotic materials greatly increased to the point where a trade network covered most of the Eastern United States. Throughout the Southeast and north of the Ohio River, burial mounds of important people were very elaborate and contained a variety of mortuary gifts, the most archaeologically certifiable sites of burial during this time were in Illinois and Ohio
