United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

West Virginia
–
West Virginia /ˌwɛst vərˈdʒɪnjə/ is a state located in the Appalachian region of the Southern United States. It is bordered by Virginia to the southeast, Kentucky to the southwest, Ohio to the northwest, Pennsylvania to the north, West Virginia is the 9th smallest by area, is ranked 38th in population, and has the second lowest household income of the 50 United States. The capital and largest city is Charleston, West Virginia was admitted to the Union on June 20,1863, and was a key Civil War border state. The Census Bureau and the Association of American Geographers classify West Virginia as part of the Southern United States, the unique position of West Virginia means that it is often included in several geographical regions, including the Mid-Atlantic, the Upland South, and the Southeastern United States. It is the state that is entirely within the area served by the Appalachian Regional Commission. The state is noted for its mountains and rolling hills, its historically significant logging and coal mining industries and it is one of the most densely karstic areas in the world, making it a choice area for recreational caving and scientific research. The karst lands contribute to much of the states cool trout waters and it is also known for a wide range of outdoor recreational opportunities, including skiing, whitewater rafting, fishing, hiking, backpacking, mountain biking, and hunting. Many ancient man-made earthen mounds from various mound builder cultures survive, especially in the areas of Moundsville, South Charleston. The artifacts uncovered in these give evidence of village societies and they had a tribal trade system culture that crafted cold-worked copper pieces. The Iroquois drove out other American Indian tribes from the region to reserve the upper Ohio Valley as a ground in the 1670s. Siouan language tribes such as the Moneton had also recorded in the area previously. West Virginia was originally part of the British Virginia Colony from 1607 to 1776, residents of the western and northern counties set up a separate government under Francis Pierpont in 1861, which they called the restored government. Most voted to separate from Virginia and the new state was admitted to the Union in 1863, in 1864 a state constitutional convention drafted a constitution, which was ratified by the legislature without putting it to popular vote. West Virginia abolished slavery and temporarily disfranchised men who had held Confederate office or fought for the Confederacy, West Virginias history has been profoundly affected by its mountainous terrain, numerous and vast river valleys, and rich natural resources. These were all factors driving its economy and the lifestyles of its residents, a 2010 analysis of a local stalagmite revealed that Native Americans were burning forests to clear land as early as 100 BC. Some regional late-prehistoric Eastern Woodland tribes were involved in hunting and fishing, practicing the slash. Another group progressed to the more time-consuming, advanced companion crop fields method of gardening, also continuing from ancient indigenous people of the state, field space and time was given to tobacco growing through to early historic. Maize did not make a contribution to the diet until after 1150 BP

New River (Kanawha River)
–
The New River, part of the Ohio River watershed, is about 360 mi long. The river flows through the U. S. states of North Carolina, Virginia, much of the rivers course through West Virginia is designated as the New River Gorge National River, and the New River is one of the nations American Heritage Rivers. In 1975, North Carolina designated a 26. 5-mile segment of the river as New River State Scenic River, by including it in the states Natural, the segment was added to the National Wild and Scenic Rivers System the following year. The origins of the name are unclear, possibilities include being a new river that wasnt on the Fry-Jefferson map of Virginia, an Indian name meaning new waters, or the surname of an early settler. Despite its name, the New River is one of the five oldest rivers in the world geologically, the Kanawha then flows into the Ohio River at Point Pleasant, WV. Much of the course is lined with steep cliffs and rock outcrops. Portions of this corridor are now used by various railroads and highways. The New River Gorge is not only scenic, but also offers numerous opportunities for white-water recreation such as rafting and kayaking. Many open ledges along the rim of the gorge offer popular views, with favorites including Hawks Nest State Park and this structure is the third-longest single-arch bridge in the world, and is also the worlds twelfth-highest vehicular bridge, and the fourth highest in the Americas. The New River Gorge and the U. S.19 bridge crossing it are shown on the West Virginia State Quarter, the New River is formed by the confluence of the South Fork New River and the North Fork New River in Ashe County, North Carolina. It then flows north into southwestern Virginia, passing near Galax, Virginia, continuing north, the river enters Pulaski County, Virginia, where it is impounded by Claytor Dam, creating Claytor Lake. North of the dam the New River accepts the Little River and passes the city of Radford, after flowing north through Giles County, Virginia and the town of Narrows, the river crosses into West Virginia. The New River is impounded by Bluestone Dam, creating Bluestone Lake in Summers County, the Bluestone River tributary joins the New River in Bluestone Lake. Just below the dam the Greenbrier River joins the New River, near the end of the gorge the river flows by the town of Fayetteville, West Virginia. A few miles northwest of Fayetteville, much of the New Rivers flow is diverted through the 3-mile Hawks Nest Tunnel for use in power generation, the water re-enters the river just upstream of Gauley Bridge, where the New merges with the Gauley River to form the Kanawha River. The Kanawha is a tributary of the Ohio River, which in turn is a tributary of the Mississippi River, despite its name, the New River is considered by some geologists to be one of the oldest rivers in the world. The New River is home to species of freshwater game fish including bass, trout, walleye, muskellunge, crappie, bluegill, carp, flathead. The New River basin also has seven species of fish, which are the, Appalachia darter, Bigmouth chub, Bluestone sculpin, Candy darter, Kanawha darter, Kanawha minnow

North Carolina is a state in the southeastern region of the United States. The state borders South Carolina and Georgia to the south, Tennessee to the west, Virginia to the north, North Carolina is the 28th most extensive and the 9th most populous of the U. S. states. The state is divided into 100 counties, the most populous municipality is Charlotte, which is the second largest banking center in the United States after New York City. The state has a range of elevations, from sea level on the coast to 6,684 feet at Mount Mitchell. The climate of the plains is strongly influenced by the Atlantic Ocean. Most of the falls in the humid subtropical climate zone. More than 300 miles from the coast, the western, mountainous part of the state has a highland climate. North Carolina is bordered by South Carolina on the south, Georgia on the southwest, Tennessee on the west, Virginia on the north, the United States Census Bureau places North Carolina in the South Atlantic division of the southern region. So many ships have been lost off Cape Hatteras that the area is known as the Graveyard of the Atlantic, the most famous of these is the Queen Annes Revenge, which went aground in Beaufort Inlet in 1718. The coastal plain transitions to the Piedmont region along the Atlantic Seaboard fall line, the Piedmont region of central North Carolina is the states most populous region, containing the six largest cities in the state by population. It consists of rolling countryside frequently broken by hills or low mountain ridges. The Piedmont ranges from about 300 feet in elevation in the east to about 1,500 feet in the west, the western section of the state is part of the Appalachian Mountain range. Among the subranges of the Appalachians located in the state are the Great Smoky Mountains, Blue Ridge Mountains, the Black Mountains are the highest in the eastern United States, and culminate in Mount Mitchell at 6,684 feet, the highest point east of the Mississippi River. North Carolina has 17 major river basins, the five basins west of the Blue Ridge Mountains flow to the Gulf of Mexico, while the remainder flow to the Atlantic Ocean. Of the 17 basins,11 originate within the state of North Carolina, but only four are contained entirely within the states border – the Cape Fear, the Neuse, the White Oak, and the Tar-Pamlico basin. Elevation above sea level is most responsible for temperature change across the state, the climate is also influenced by the Atlantic Ocean and the Gulf Stream, especially in the coastal plain. These influences tend to cause warmer winter temperatures along the coast, the coastal plain averages around 1 inch of snow or ice annually, and in many years, there may be no snow or ice at all. North Carolina experiences severe weather in summer and winter, with summer bringing threat of hurricanes, tropical storms, heavy rain

Ohio River
–
The Ohio River, which streams westward from Pittsburgh, Pennsylvania, to Cairo, Illinois, is the largest tributary, by volume, of the Mississippi River in the United States. The 981-mile river flows through or along the border of six states, through its largest tributary, the Tennessee River, the basin includes many of the states of the southeastern U. S. It is the source of drinking water for three million people and it is named in Iroquoian or Seneca, Ohi, yó, lit. Good River or Shawnee, Pelewathiipi and Spelewathiipi, the river had great significance in the history of the Native Americans, as numerous civilizations formed along its valley. For thousands of years, Native Americans used the river as a major transportation, in 1669, René-Robert Cavelier, Sieur de La Salle led a French expedition to the Ohio River, becoming the first Europeans to see it. After European-American settlement, the served as a border between present-day Kentucky and Indian Territories. It was a transportation route for pioneers during the westward expansion of the early U. S. In his Notes on the State of Virginia published in 1781–82, Thomas Jefferson stated and its current gentle, waters clear, and bosom smooth and unbroken by rocks and rapids, a single instance only excepted. During the 19th century, the river was the boundary of the Northwest Territory. Where the river was narrow, it was the way to freedom for thousands of slaves escaping to the North, many helped by free blacks and whites of the Underground Railroad resistance movement. The Ohio River is a transition area, as its water runs along the periphery of the humid subtropical. It is inhabited by fauna and flora of both climates, in winter, it regularly freezes over at Pittsburgh but rarely further south toward Cincinnati and Louisville. At Paducah, Kentucky, in the south, near the Ohios confluence with the Mississippi, Paducah was founded there because it is the northernmost ice-free reach of the Ohio. The Ohio River is formed by the confluence of the Allegheny and Monongahela rivers at Point State Park in Pittsburgh, from there, it flows northwest through Allegheny and Beaver counties, before making an abrupt turn to the south-southwest at the West Virginia–Ohio–Pennsylvania triple-state line. From there, it forms the border between West Virginia and Ohio, upstream of Wheeling, West Virginia, the river then follows a roughly southwest and then west-northwest course until Cincinnati, before bending to a west-southwest course for most of its length. The course forms the borders of West Virginia and Kentucky. The Ohio drains parts of 15 states in four regions, northeast New York, a small area of the southern border along the headwaters of the Allegheny. Pennsylvania, a corridor from the corner to north central border

Charleston, West Virginia
–
Charleston is the capital and largest city of the U. S. state of West Virginia. It is located at the confluence of the Elk and Kanawha Rivers in Kanawha County, as of the 2013 Census Estimate, it had a population of 50,821, while its metropolitan area had 224,743. It is a center of government, commerce, and industry, early industries important to Charleston included salt and the first natural gas well. Later, coal became central to economic prosperity in the city, today, trade, utilities, government, medicine, and education play central roles in the citys economy. The first permanent settlement, Ft. Lee, was built in 1788, in 1791, Daniel Boone was a member of the Kanawha County Assembly. Charleston is the home of the West Virginia Power minor league team, the West Virginia Wild minor league basketball team. Yeager Airport and the University of Charleston are also located in the city, West Virginia University and the WVU Institute of Technology, Marshall University, and West Virginia State University also have higher education campuses in the area. Charleston is also home to McLaughlin Air National Guard Base of the West Virginia Air National Guard, after the American Revolutionary War, pioneers began making their way out from the early settlements. Many slowly migrated into the part of Virginia. Capitalizing on its resources made Charleston an important part of Virginia. Today, Charleston is the largest city in the state and the state capital, Charlestons history goes back to the 18th century. Thomas Bullitt was deeded 1,250 acres of land near the mouth of the Elk River in 1773 and it was inherited by his brother, Cuthbert Bullitt, upon his death in 1778, and sold to Col. George Clendenin in 1786. The first permanent settlement, Fort Lee, was built in 1787 by Col. Savannah Clendenin and this structure occupied the area that is now the intersection of Brooks Street and Kanawha Boulevard. Historical conjecture indicates that Charleston is named after Col. Clendenins father, Charles Town was later shortened to Charleston to avoid confusion with another Charles Town in eastern West Virginia, which was named after George Washingtons brother Charles. Six years later, the Virginia General Assembly officially established Charleston, on the 40 acres that made up the town in 1794,35 people inhabited seven houses. Charleston is part of Kanawha County, the origin of the word Kanawha, Kanawha, derives from the regions Iroquois dialects meaning water way or Canoe Way implying the metaphor, transport way, in the local language. It was and is the name of the river flows through Charleston. The grammar of the hard H sound soon dropped out as new arrivals of various European languages developed West Virginia, the phrase has been a matter of Register

Indigenous peoples
–
Groups are usually described as indigenous when they maintain traditions or other aspects of an early culture that is associated with a given region. Not all indigenous peoples share such characteristics, Indigenous societies are found in every inhabited climate zone and continent of the world. Estimates put the population of indigenous peoples from 220 million to 350 million. The adjective indigenous is derived from the Latin word indigena, which is based on the root gen- to be born with a form of the prefix in in. Any given people, ethnic group or community may be described as indigenous in reference to some particular region or location that they see as their tribal land claim. Other terms used to refer to indigenous populations are aboriginal, native, original, james Anaya, former Special Rapporteur on the Rights of Indigenous Peoples, has defined indigenous peoples as living descendants of pre-invasion inhabitants of lands now dominated by others. They are culturally distinct groups that find themselves engulfed by other settler societies born of forces of empire, throughout history, different states designate the groups within their boundaries that are recognized as indigenous peoples according to international or national legislation by different terms. Their ability to influence and participate in the policies that may exercise jurisdiction over their traditional lands. The presence of external laws, claims and cultural mores either potentially or actually act to constrain the practices and observances of an indigenous society. These constraints can be observed even when the society is regulated largely by its own tradition. They may be imposed, or arise as unintended consequence of trans-cultural interaction. They may have an effect, even where countered by other external influences. This definition has some limitations, because the definition applies mainly to pre-colonial populations, the primary impetus in considering indigenous identity comes from the post-colonial movements and considering the historical impacts on populations by the European imperialism. Greek sources of the Classical period acknowledge the existence of indigenous people. These peoples inhabited lands surrounding the Aegean Sea before the subsequent migrations of the Hellenic ancestors claimed by these authors, the disposition and precise identity of this former group is elusive, and sources such as Homer, Hesiod and Herodotus give varying, partially mythological accounts. However, it is clear that cultures existed whose indigenous characteristics were distinguished by the subsequent Hellenic cultures, greco-Roman society flourished between 250 BC and 480 AD and commanded successive waves of conquests that gripped more than half of the globe. The rapid and extensive spread of the various European powers from the early 15th century onwards had an impact upon many of the indigenous cultures with whom they came into contact. The Canary Islands had an indigenous population called the Guanches whose origin is still the subject of discussion among historians, the United Nations estimates that there are over 370 million indigenous people living in over 70 countries worldwide

Archaeology
–
Archaeology, or archeology, is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, Archaeology can be considered both a social science and a branch of the humanities. In North America, archaeology is considered a sub-field of anthropology, archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology as a field is distinct from the discipline of palaeontology, Archaeology is particularly important for learning about prehistoric societies, for whom there may be no written records to study. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of literacy in societies across the world, Archaeology has various goals, which range from understanding culture history to reconstructing past lifeways to documenting and explaining changes in human societies through time. The discipline involves surveying, excavation and eventually analysis of data collected to learn more about the past, in broad scope, archaeology relies on cross-disciplinary research. Archaeology developed out of antiquarianism in Europe during the 19th century, Archaeology has been used by nation-states to create particular visions of the past. Nonetheless, today, archaeologists face many problems, such as dealing with pseudoarchaeology, the looting of artifacts, a lack of public interest, the science of archaeology grew out of the older multi-disciplinary study known as antiquarianism. Antiquarians studied history with attention to ancient artifacts and manuscripts. Tentative steps towards the systematization of archaeology as a science took place during the Enlightenment era in Europe in the 17th and 18th centuries, in Europe, philosophical interest in the remains of Greco-Roman civilization and the rediscovery of classical culture began in the late Middle Age. Antiquarians, including John Leland and William Camden, conducted surveys of the English countryside, one of the first sites to undergo archaeological excavation was Stonehenge and other megalithic monuments in England. John Aubrey was a pioneer archaeologist who recorded numerous megalithic and other monuments in southern England. He was also ahead of his time in the analysis of his findings and he attempted to chart the chronological stylistic evolution of handwriting, medieval architecture, costume, and shield-shapes. Excavations were also carried out in the ancient towns of Pompeii and Herculaneum and these excavations began in 1748 in Pompeii, while in Herculaneum they began in 1738. The discovery of entire towns, complete with utensils and even human shapes, however, prior to the development of modern techniques, excavations tended to be haphazard, the importance of concepts such as stratification and context were overlooked. The father of archaeological excavation was William Cunnington and he undertook excavations in Wiltshire from around 1798, funded by Sir Richard Colt Hoare. Cunnington made meticulous recordings of neolithic and Bronze Age barrows, one of the major achievements of 19th century archaeology was the development of stratigraphy. The idea of overlapping strata tracing back to successive periods was borrowed from the new geological and paleontological work of scholars like William Smith, James Hutton, the application of stratigraphy to archaeology first took place with the excavations of prehistorical and Bronze Age sites

Adena culture
–
The Adena culture was a Pre-Columbian Native American culture that existed from 1000 to 200 BC, in a time known as the Early Woodland period. The Adena culture refers to what were probably a number of related Native American societies sharing a burial complex, the Adena lived in an area including parts of present-day Ohio, Indiana, Wisconsin, West Virginia, Kentucky, New York, Pennsylvania and Maryland. The importance of the Adena complex comes from its influence on other contemporary. The Adena culture is seen as the precursor to the traditions of the Hopewell culture, the Adena culture was named for the large mound on Thomas Worthingtons early 19th-century estate called Adena, in Chillicothe, Ohio. Lasting traces of Adena culture are seen in their substantial earthworks. At one point, Adena mounds numbered in the hundreds, and these mounds generally ranged in size from 20 feet to 300 feet in diameter and served as burial structures, ceremonial sites, historical markers and possibly gathering places. These mounds were built using hundreds of thousands of full of specially selected and graded earth. According to archaeological investigations, Adena mounds were built as part of burial ritual. These mortuary buildings were intended to keep and maintain the dead until their burial was performed. Before the construction of the mounds, some utilitarian and grave goods would be placed on the floor of the structure, the mound would then be constructed, and often a new mortuary structure would be placed atop the new mound. After a series of repetitions, mound/mortuary/mound/mortuary, a quite prominent earthwork would remain, in the later Adena period, circular ridges of unknown function were sometimes constructed around the burial mounds. Adena mounds stood in isolation from domestic living areas, although the mounds are beautiful artistic achievements themselves, Adena artists created smaller, more personal pieces of art. Art motifs that became important to many later Native Americans began with the Adena, motifs such as the weeping eye and cross and circle design became mainstays in many succeeding cultures. Many pieces of art seemed to revolve around shamanic practices, and this may indicate a belief that the practice imparted the animals qualities to the wearer or holder of the objects. Deer antlers, both real and constructed of copper, wolf, deer and mountain lion jawbones, and many objects were fashioned into costumes, necklaces. Distinctive tubular smoking pipes, with flattened or blocked-end mouthpieces. The objective of pipe smoking may have been altered states of consciousness, all told, Adena was a manifestation of a broad regional increase in the number and kind of artifacts devoted to spiritual needs. The Adena also carved stone tablets, usually 4 or 5 inches by 3 or 4 inches by.5 inches thick

Earthworks (archaeology)
–
In archaeology, earthworks are artificial changes in land level, typically made from piles of artificially placed or sculpted rocks and soil. Earthworks are often known as barrows in England, and mounds in North America, Earthworks can themselves be archaeological features, or they can show features beneath the surface. They are believed to have used as monuments for spiritual ritual ceremonies. Long barrows are oblong-shaped mounds that are used for burials, tumuli are mounds of earth created over a tomb, it has the same meaning as barrow. A cross dyke or cross-ridge dyke is a bank and ditch, found in Europe and often belonging to the later Bronze Age or Iron Age. Often marked on Ordnance Survey maps in the UK. Ridge and furrows are sets of parallel depressions, mottes are mound structures made of earth and stone that once held castles. A round barrow is a mound that is in a shape that was used during Neolithic times as a burial mound. Geoglyph, a design or motif Earthworks can vary in height from a few centimetres to the size of Silbury Hill at 40 metres. They can date from the Neolithic to the present, the structures can also stretch for many tens of kilometres. In area, they can cover many hectares, for example, Maiden Castle, shallow earthworks are often more visible as cropmarks or in aerial photographs if taken when the sun is low in the sky and shadows are more pronounced. Similarly, earthworks may be visible after a frost or a light dusting of snow. Earthworks can be detected and plotted using Light Detection and Ranging and this technique is particularly useful for mapping small variations in land height that would be difficult to detect by eye. It can be used to map features beneath forest canopy and for features hidden by other vegetation, LIDAR results can be input into a geographic information system to produce three-dimensional representations of the earthworks. An accurate survey of the earthworks can enable them to be interpreted without the need for excavation, for example, earthworks from deserted medieval villages can be used to determine the location, size, and layout of lost settlements. Often these earthworks can point to the purpose of such a settlement, Earthworks in North America include mounds built by Native Americans known as the Mound Builders. Ancient people who lived in the American Midwest commonly built effigy mounds, possibly the most famous of these effigy mounds is Serpent Mound. Located in the Ohio, this 411-meterlong earthen work is thought to memorialize alignments of the planets, cone-shaped or conical mounds are also numerous, with thousands of them scattered across the American Midwest, some over 80 feet tall. These conical mounds appear to be marking the graves of one person or even dozens of people

Fort Ancient
–
They were a maize-based agricultural society who lived in sedentary villages and built ceremonial platform mounds. The Fort Ancient culture was thought to have been an expansion of the Mississippian cultures. It is now accepted as a developed culture that descended from the Hopewell culture. The Fort Ancient Cultures most famous mound is called the serpent mound, the name of the culture originates from the Fort Ancient, Ohio archeological site. However, the Fort Ancient Site is now thought to have built by Ohio Hopewellian people. It was likely occupied later by the succeeding Fort Ancient culture, the site is located on a hill above the Little Miami River, close to Lebanon, Ohio. Starting in about 1000 CE, terminal Late Woodland groups in the Middle Ohio Valley adopted maize agriculture and they began settling in small, year-round nuclear family households and settlements of no more than 40 to 50 individuals. These small scattered settlements, located along terraces that overlooked rivers and sometimes on flood plains, by 1200 the small villages began to coalesce into larger settlements of up to 300 people. They were occupied for longer periods, possibly up to 25 years, during the Early and Middle Fort Ancient period, the houses were designed as single-family dwellings. Later Fort Ancient buildings are larger multi-family dwellings, settlements were rarely permanent, as the people commonly moved to a new location after one or two generations, when the natural resources surrounding the old village were exhausted. The people laid out the villages around an oval central plaza. The arrangement of buildings in Fort Ancient settlements is thought to have served as a sort of calendar, marking the positions of the solstices. The people began to build low platform mounds for ceremonial purposes, the plaza was the center of village life, the place where ceremonies, games and other social events were held. The Late Fort Ancient period from 1400 to 1750 is the era in the Middle Ohio Valley. During this era, the formerly dispersed populations began to coalesce, the Gist-phase villages became much larger than during the preceding period, with populations as high as 500. This era also showed increased contact with Mississippian peoples, some of whom may have migrated to and these sites were abandoned during this time period. During the Montour phase, the people inhabited their villages year-round and this may indicate that during the winter, family groups and hunting parties may have returned to the regions previously occupied by their ancestors. Such a pattern was observed during historic times, for example, such artifacts appeared and were used in the area before the arrival of European explorers or settlers
