possible migration paths to Virginia from Asia or even Europe

The first people to occupy Virginia, known as Paleo-Indians, came here from elsewhere. Where they came from, and how they got here, is still a matter of dispute.
The first humans to occupy North American may have walked here from Siberia, crossing the Bering land bridge as they hunted for game and gathered plant foods. Perhaps 25,000 years ago, Siberians migrated into Beringia. They may have stayed there for 10,000 years during the Last Glacial Maximum, isolated on a 1,000 mile wide grassland of northwestern Siberia and far western Alaska, plus what is now the seafloor beneath the Bering Strait..
On the east, the Cordilleran Ice Sheet covered the mountains along Alaska's coastline and icebergs calved off the edge into the Pacific Ocean. During the Last Glacial Maximum, that ice sheet coalesced with the Laurentide Ice Sheet further inland. The two ice sheets extended from the frozen Arctic Ocean to the Pacific Ocean. A complete barrier of ice is presumed to have blocked humans from moving into the interior of Alaska or the rest of North America.1
The humans isolated in Beringia were not seeking to move in any particular direction in order to escape their climate-based trap in Beringia. Unlike Columbus in 1492, they were not consciously on a journey to discover a new path to the other side of the world. Unlike the crew of the USS Enterprise in modern Star Trek movies, they were not tasked by a government to push the boundary of human knowledge, to "go where no man has gone before."
They were hunters and gatherers, exploring in search of another meal.
People living in Beringia probably adopted a seasonal pattern of moving around, returning each year to sites known to be rich in ripening plants or migrating animals such as caribou. At each campsite, local food resources were soon exhausted. On a regular basis, they packed up their stone and bone tools, furs, and everything else they owned, then set out to find new plants with edible seeds/fruits and more animals such as woolly mammoths that would reduce hunger for the moment.
Old campsites would be re-visited if there were good food sources nearby. Returning to an old site would require less time to gather stones to make a hearth, or small tree trunks to be used as tent poles. Otherwise, everything they owned was carried from place to place, hung from their waists and on their backs/shoulders. One of the first steps in making camp would have been stripping off the sacks made from skins of animals and woven bags made from plant fibers.
There were no permanently-occupied houses, because no location offered a year-round source of food sufficient to feed an entire hunting band. Paleo-Indians were migrants, constantly on the move.

Perhaps 8,000 to 10,000 migrants were isolated in Beringia for 10,000 or so years. They adapted to the cold climate, and survived on the ice-free steppe and tundra that was suitable for hunting and gathering. For centuries, the ice sheets blocked travel to the east.
Humans probably tried to walk across the Cordilleran Ice Sheet and Laurentide Ice Sheet. Adventurous or starving hunters, or those trying to get away from rivals who were threats, might have packed food and traveled a few days deep into the ice sheets. Leaders of hunting bands may have looked for a path through the ice to new territory to avoid conflict with rivals. Spiritual visionaries may have spurred expeditions onto the ice.
The constraints to moving out of Beringia were food and fuel. Where ice covered the soil completely, there were no dwarf birch, willows or other shrubs to provide materials for building any form of shelter. Plants were required as fuel for initial fires that would grow hot enough to ignite the marrow in large mammal bones, the greatest source of energy available for keeping warm.
Bands of earliest Americans could explore east from the shrub tundra onto the ice sheet during the Last Glacial Maximum. They might find shelter from the winds by sleeping in large cracks within the moving ice sheets, but could survive only briefly without plants and animals for resupplying food. Without vegetation for fuel, even melting ice for drinking water would have been a challenge.
For a long time there was nothing to find inland from the ocean's shoreline but ice and more ice. Short explorations on the ice sheet were feasible, but no one returned from a trip into the ice-covered interior of Alaska that lasted longer than the food supply carried by the traveler(s).

Despite the presumed constraints of crossing ice sheets that offered no food or fuel, the assumption that no one succeeded during the last Glacial Maximum may have to be reconsidered. In 2017, scientists published details of the discovery of a site in the northwestern Yukon of Canada where humans had lived 24,000 years ago.
They may have migrated there before the ice sheets spread to their greatest extent 26,000 years ago at the Last Glacial Maximum. At that point, the ice blocked passage further south, but somehow those first North American residents reached the Bluefish Caves in Yukon Territory before the Laurentide Ice Sheet retreated.2

The climate grew warmer at the end of the Ice Age, and land once covered by the ice sheets was exposed. An ice-free corridor opened up first along the edge of the Pacific Ocean. Immigrants originally from Siberia could have reached California by walking along the western edge of the melting Cordilleran Ice Sheet.
17,000 years ago, sea levels were nearly 400 feet lower than today. The shoreline along which the Paleo-Indians walked was 50-75 miles further west than the modern land-water edge. Many of the original campsites of those immigrants are deep underneath the surface of the Pacific Ocean, but parts of the ancient British Columbia shoreline has "bounded back" as glaciers retreated. Discovery and research into sites there could provide evidence of the migration.3

If the first humans to move south from Beringia used the shoreline route, they ate seafood on their journey. Humans reached Triquet Island 14,000 years ago and occupied Monte Verde in Chile 14,500 years ago.4
It is possible that the sites occupied on Triquet Island and Monte Verde were not at the beginning of the immigration. By some route not yet identified, people had already moved inland from the Pacific coast. Evidence at Cactus Hill, along the Nottoway River in Virginia, suggests that site was occupied by Paleo-Indians as long as 18-20,000 years ago. People lived in what is now called the Meadowcroft Rockshelter in western Pennsylvania between 16,000 and 14,000 years ago.5
The eastern edge of the Cordilleran Ice Sheet and the western edge of the Laurentide Ice Sheet finally melted roughly 13,000 years ago (BP, for "Before Present"). A gap between the two ice sheets opened up an inland route south, after enough ice retreated to open land between the ice sheet and meltwater lakes and plants grew on that land.
The gap between the western edge of the Cordilleran Ice Sheet and the eastern edge of the Laurentide Ice Sheet developed after the initial migration into what today is the continental United States. The Clovis culture evolved 2,000 or more years later, after the initial occupation of North America.6
There is an alternative possibility to the Siberians-migrated-via-Beringia hypothesis. In addition to the migrants from Asia, some of the first people in North America could have arrived from Europe by boat, moving along the Atlantic Ocean coastline and hunting marine mammals at the edge of the ice.
The Clovis points found in some of the earliest archeological sites in North America, and perhaps the point dredged up together with mammoth remains from the bottom of the Atlantic Ocean off the Eastern Shore, might be consistent with the theory that North America was settled by people from the Solutré region in France. There is even the possibility that some humans reached California 130,000 years ago, based on one set of mastodon bones with fractures that may have been caused by tools.7
The isolation of Paleo-Indians traveling in separate family groups would have been mitigated somewhat by "man's best friend." Dogs had migrated together with humans across the Beringia land bridge. Most likely, the first dogs in Virginia served as domesticated pets as well as hunting companions.8

The first humans to settle in Virginia, the Paleo-Indians who immigrated here roughly 15,000 years ago, were hunters and gatherers. They traveled widely in family-based groups, acquiring food in various places and then moving to new places when local resources were exhausted.
Assuming Paleo-Indians slept in shelters made from fiber mats or skins, they had to haul their roofing materials by hand whenever they moved. The traveling bands may have set up temporary camps with a natural wooden roof, after finding places where windstorms had knocked down enough trees to create dry spots for a few individuals. Natural shelters would have been very limited. Some Virginia caves and rock overhangs were used, but there were few such sites east of the Blue Ridge.9
The lives of each band, and the prestige and marriage potential of each hunter, depended the effectiveness and efficiency of each hunting and gathering expedition. During the initial migration into North America, there may have been a constant process of experimentation. Food gathering and cooking techniques, spiritual beliefs, and a wide range of behaviors must have changed as the new continent was explored for the first time, but speculation is required to understand their lifestyles. Only stone artifacts have survived to reveal the ancient cultural adaptations to different environments.
Hunters crafted points from bone, shell, antler, and wood as well as different types of stone. The Paleo-Indians must have tried making points with different shapes and types of edges as they encountered new plants and animals to convert into food and clothing. The evolution of points demonstrates that people tried to improve upon existing tools to be more successful when hunting different types of animals, and changing forms and materials used for knives/scrapers/awls suggest shifts in population.
Clovis Points, with distinctive "flute" of stone chipped out of the center at the base
Source: National Park Service, Southeastern Prehistory - Paleoindian Period
One of the oldest point designs, the "Clovis" point, is common in Paleo-Indian sites across North America. The namesake discovery site is the town of Clovis in New Mexico, but Clovis points are found in some of the oldest archeological sites in Virginia.
Most archeologists believe Paleo-Indians migrated first into the western side of North America, but the greatest concentration of Clovis points is on the eastern side of North America. There are no precursors to the Clovis point in Siberia or Alaska. That design appears to have been developed in North America, and was in use for 300-400 years. It could have started east of the Mississippi River, and through cultural diffusion spread westward to the Pacific Ocean.10
The Clovis point has a distinctive groove or "flute" in the center. The first people to make a Clovis point might have done so by accident. Logically, removing stone from the middle of the point could weaken it. A weaker point would crack easier, forcing the band to spend time finding a new quarry site and making more replacements. Time spent replacing points would cut into the time available for collecting food. Making a less-reliable point would appear to be counter-productive, yet Paleo-Indians continued making Clovis points for 300-400 years.
Clovis points were also harder to manufacture. Each point required about 30 minutes to make by "knapping" stone using pressure to peel off flakes. Near the end of the process, 10-20% of points were ruined when removing slices of stone to create the groove. The shape had to offer some advantage, to be worth the extra effort required in the manufacturing process.
One obvious advantage of the groove is that it reduced the weight of the point, allowing a hunter to throw a spear farther/faster. The shape also may have reduced aerodynamic drag.
Testing has revealed a third advantage. The groove causes the point to crush near the base unpon a hard impact, but protects the point from cracking in the middle. A Clovis point that hit hard bone in an animal could be reworked easily into a shorter, but still fully serviceable tip for a spear. An archeologist who identified the "shock absorber" advantage of the groove noted:11

Spears tipped with Clovis points were useful in hunting large wild animals throughout North America. The initial developers of the Clovis point held no patent, and Paleo-Indian technology was widely imitated as hunters and gatherers ranged across fields and forests throughout that part of North America not covered by the Laurentide Ice Sheet.
Clovis and other point styles from the Paleo Period

Because we find essentially the same style of point in many different locations, it appears that bands of people traveled widely and interacted with each other regularly. Archeologists recognize differences between types of fluted points crafted in different places over the three-four centuries that the Clovis design was popular.
The rapid adoption of the Clovis point design would not have been possible if Paleo-Indian groups lived in isolation from each other by separate languages or hostile behavior. There must have been physical and cultural barriers, but at least in the Clovis period they were not high enough to cause separate, independent technologies to be restricted to certain locations.
Some caches of unused and unusually large Clovis points appear to be ceremonial stones rather than functional spearpoints. The spread of the design may reflect the rapid spread of a spiritual belief among different groups, rather than adoption of a particular shape because it was more effective in killing mastodons.12
As one author noted:13
Archeologists have identified specific quarry sites from which Paleo-Indians extracted stone to make tools such as Clovis points. For thousands of years, groups regularly visited the jasper outcrop near Flint Run, on the South Fork of the Shenandoah River in Warren County. The quality of that stone for manufacturing replacement points, knives, scrapers, and other stone tools for another season of hunting and gathering was work the trip.
It appears some people even stayed there. The oldest known structure in Virginia - perhaps a house, perhaps a tool-making factory - was found at the Thunderbird site designated as 44WR11. Dr. William Gardner and his wife Dr. Joan Walker excavated the site for 15 years, starting in 1971. The National Park Service designated the Thunderbird Archeological District as a National Historic Landmark in 1977.
Close examination of a point discovered at Thunderbird showed evidence that it had been used on some form of cat, perhaps a saber-toothed tiger. Points found at the nearby Fifty Site showed evidence of rabbit and bear. Paleo-Indians in Virginia hunted far more species than just mastodons.14
Thunderbird is the only identified Paleo-Indian site where public visits have been encouraged. For several years a museum and archeological park located at the site provided public education, but the museum is gone. The archeological site is now subdivided and surrounded by modern houses. After excavations were completed, four lots were purchased by Archeological Society of Virginia and are the only part of the 1,800-acre site now protected by easement.15

Paleo-Indians in Virginia developed other quarries besides those at Thunderbird. The chert outcrop at the Williamson site in Dinwiddie County supplied "Cattail Creek Chalcedony" for the bands hunting in what is now southern Virginia.
The jasper outcrop at Brook Run in Culpeper County may have been discovered and utilized by Paleo-Indians as well. We find evidence from just later periods at that site, but the evidence of the first users of that stone may have been destroyed by the continued extensive quarrying in the Archaic Period.16
Paleo-Indians developed "point" designs other than Clovis. Shafts and handles were made from bone and wood, so only the points of weapons used for hunting and for fighting other people have survived for later discovery by archeologists.
Each hunter may have made some sort of fiber/skin basket or backpack to carry their gear from campsite to campsite, before lightening the load and carrying only selected weapons for an actual hunt. Paleo-Indian camping gear would have included specialized stone tools, used for specific purposes. They carried spearpoints to kill animals, knives to cut a carcass into chunks that could be carried back to camp, scrapers to separate flesh from skin to make clothing, and awls to drill holes in skins before sewing pieces together.
The stone/shell/bone/wood tools would have been wrapped in fiber/skin "wallets" or sacks, in part to leave the traveler's hands free but also to prevent damage to the sharp edges of the tools. People packed carefully, though lightly, to avoid damaging their stone tools during transport.
Paleo-Indians could chip off a stone flake for one-time use in just seconds, but it took precious time to create a sharp edge on a specialized tool. The first people in North America spent the majority of their time, perhaps 80%, hunting and gathering their next meal. Points were re-sharpened as needed, and new tools were made constantly as wear and tear blunted edges. By one estimate, a family group used roughly 100 pounds of stone annually.17
"Food security" was low, so ecological sensitivity was high. Paleo-Indians were skilled geologists as well as skilled wildlife biologists, botanists, meteorologists, etc. They were able to distinguish the high-quality lithic materials of cryptocrystalline stone (jasper, chert, chalcedony, and other silica-rich rocks), forms of quartz that chipped easily and held a sharp edge longer.18
Some stone was acquired from specialized quarry sites, including the Thunderbird Quarry on Flint Run near Front Royal. Often, tools were manufactured from whatever was available when it was needed during seasonal travels into different habitats. For simple tasks, perhaps slicing up a carcass for a meal, a rock could be found, shaped, used, and discarded. Only the specialized tools, made from preferred rock types, were worth carrying around from place to place.

Hunting bands may have killed moose, elk, caribou, and deer in the open grasslands, spruce-fir forests, and river valleys filled with deciduous trees at the end of the Ice Age. Wild game may have been more limited on the wind-swept bare mountaintops or on mountain slopes with just a few scattered trees. Virginia's first hunters probably spent much of their time in the lowlands such as the Shenandoah Valley. Constant movement enabled the Paleo-Indians to find new herds of large (and small) mammals, as well as to gather some wild seeds and fruits.
They also hunted or scavenged mastodon that had managed to remain in Virginia as the climate changed. What could be a tool manufactured from the tibia bone of a musk ox has been excavated at Saltville, from a site where a single mastodon may have been butchered and burned 15,000 years ago.19
There is one other mastodon excavation site in Virginia, near Yorktown. Bones there were preserved from decay in the acid Virginia soil because the animal died on a bed of oyster shells where the pH was higher, in a layer of sediments that geologists later named the Yorktown Formation. Radiocarbon dates indicate the animal died over 16,000 years ago.
Killing a mastodon must have provided an immense amount of food, perhaps more than one band of hunters/gatherers could consume before it spoiled. Almost all of the arm and leg bones at the Yorktown site are missing. Marks on remaining bones may be cuts from stone knives as the rest of the meat was removed. Those early Virginians may have butchered the mammoth and carried away the choice parts, leaving much of the meat behind.20
Elsewhere in the Southeast, it is clear that Paleo-Indians hunted large game before the Clovis point was developed. Between 11,000 and 13,000BCE, they butchered a mastodon on the edge of a pond at the Coats-Hines archaeological site south of Nashville, Tennessee. There is also clear archeological evidence that humans killed a mastodon 14,550 years ago at the Page-Ladson site on the Aucilla River in Florida. That was roughly 1,500 years before the Clovis point was developed, and 2,000 years before mastodons went extinct in the area.21

The stereotype of the first Virginians being big-game hunters, traveling great distances in small hunting parties and spearing mammoths/mastodons for a meal every week, may be completely inappropriate for Virginia and even elsewhere in North America. Because the Clovis points were large, there was assumption that it was used to hunt large mammals. The Big Game Hunting hypothesis has now been supplanted by an assumption that:22
Killing a mastodon may have required separate family groups to unite in the effort, and there were easier sources of food that exposed hunter-gatherers to lower risks. A megafauna kill could have been a rare ceremonial event with great social and symbolic significance rather than just a routine hunting exercise. If mastodons in Virginia were not hunted primarily for food, one possibility is:23
The Paleo-Indians interacted with other family groups, traveling great distances to obtain food. It is unlikely that different groups had well-defined hunting/gathering territories. Similar to modern humans, Paleo-Indians were social animals seeking the company of others for trade, marriage partners, and entertainment.

Population levels were low, based on the small number of artifacts recovered from the Paleo-Indian Period compared to the later Archaic Period. During the Paleo-Indian Period within Virginia, different small family units with shared family connections may have gathered occasionally in three to eight large macrobands for hunting large game.
In their travels, the bands returned regularly to quarries at Flint Run and Williamson to extract their preferred cryptocrystalline stone to restock their tool kit. The quarries were rare sources of chalcedony, chert, and jasper, forms of silica like quartz, that made sharp edges when shaped skillfully through percussion (hammering to crack off large pieces) and pressure (to remove smaller, specific flakes). There is evidence that 20 different groups used separate spots at Flint Run for collecting and processing the rock into tools.24
Each Paleo-Indian band included roughly 25 members. Groups who lived together were based on close family connections; only later would different families share the same space and develop into tribal groups.
The initial interactions between bands of strangers armed with spears and razor-sharp stone knives must have been stressful, but the need to find mates outside the family would have spurred regular social interaction. When groups met, it is reasonable to assume they traded information and also special objects, such as shiny shells and stones preferred for making tools. The "first date" between adolescents in other hunting bands would have been followed by a quick decision to select a mate, before the bands traveled in different directions for perhaps another year.
The roaming family units may have used gaps through the Blue Ridge as the geographic locators of where to meet, with repeated visits to the eastern edge of the mountains.
Archeologist Mike Johnson has suggested that macro-bands (groups larger than single families, but not organized into tribes independent of family kinship) may have used the passes through the Blue Ridge to identify "meet-up" sites. Two candidates for gathering to trade, socialize, and find new partners are Smith Mountain Gap (Pittsylvania County) and Thoroughfare Gap (Prince William County).
Some of the oldest human-created artifacts in Virginia have been revealed at excavations at the eastern edge of Smith Mountain Gap, on the eroding shoreline of the pumped storage hydropower reservoir between Smith Mountain Dam and Leesville Dam. That location provided an easy-to-identify slot in the Blue Ridge, recognizable from as far as 30 miles away on the eastern side. Before the Roanoke River was dammed, anadromous fish such as Atlantic salmon would have swum far upstream, providing an extra food source for a rendezvous there in May/June.

Travelers from the east could have brought brightly-colored shells from the Atlantic Ocean, located 40 miles further east from the current shoreline. During the Ice Age, sealskins were readily available at the latitude of modern Virginia. Ocean-based items would have been especially valued by Paleo-Indians living west of the Blue Ridge.
Travelers from the west could have brought trade items from the Mississippi River valley, via the Kanawha River connection to the Ohio River. Perhaps the item of greatest interest would have been different forms of stone valued for utility (after being worked into tools) or for other cultural reasons. Paoli chert from the Big Sandy River drainage in Kentucky has been identified at Leesville Lake; Paleo-Indians transported it there for a reason.25

The predictive model allows archeologists to target specific sites for research, rather than rely upon chance discovery. Specific criteria entered into a Geographic Information System (GIS) can suggest where, 10-15,000 years ago, traveling bands of hunters would have said "let's meet there, to trade and party" at a particular time of year.
Even without GIS technology or archeological expertise, it is possible to recognize distinctive locations. For example, a sandstone outcrop offering a spectacular view from the west side of the Blue Ridge near the Loudoun/Clarke county line known as Bears Den may have been a gathering point.

The first Virginians moved often through the course of a year. Groups living near a source of stone for their tools (Paleo-Indian quarries) may have traveled less than groups living on the Coastal Plain, where there were fewer rocks that were easy to fracture into tools that held their sharp edges. Paleo-Indians in Virginia probably:26
On Spout Run near the Shenandoah River in Clark County, an archeologist has claimed that a series of concentric stone circles (designated site 44CK151) could be a 12,000-year old observatory. Jack Hranicky hypothesized that Paleo-Indians, after quarrying jasper for tools at Thunderbird, walked down the Shenandoah River and held some sort of cultural ceremonies at the Spout Run site.
Petroglyphs in the shape of foot prints could be intended to mark where to stand in order to observe an equinox - or the arrangement of the rocks could also be natural, with alignments created by just gravity and erosion over time. If it was built in the Paleo-Indian period to mark the summer/winter solstices and fall/spring equinoxes, the Spout Run site is unique.
Modern scholars have identified only one other possible solar observatory in Virginia. Hand glyphs in a rock shelter at Little Mountain in Nottoway County are illuminated by sunlight only around the winter solstice. The relationship between sunlight and that rock art, painted much later in the Woodland Period, may be just coincidental.
Accepting that humans arranged the rocks at Spout Run over 10,000 years ago to create a solar observatory, but constructed zero or just one other calendar sites, will always be a challenge. Perhaps there were more calendar sites, but they were disrupted by farmers who occupied the lands in the 1600's and 1700's. Pehaps modern archeologists have just failed to see the evidence. Or perhaps the change in culture at the end of the Paleo-Indian period included the loss of astronomical understanding.27
The end of the Paleo-Indian period, and the start of the Archaic period, is marked by new designs of points. The distinctive fluted point, with the flake removed from the center, is replaced by notches on the side. That may reflect a different technique for attaching the point to a wooden shaft.
At the end of the Ice Age, human travel and settlement patterns were affected by the emergence of new habitats and new food sources. In Virginia, large mammals such as the mastodon were replaced with deer and other smaller game animals. Deciduous forests replaced open grasslands, offering nutritious hickory nuts and even acorns. Estuaries on the Coastal Plain stabilized, followed by an increase on accessible oysters, clams, and crabs. Anadromous fish swam up river valleys to the Fall Line, offering yet another source of protein and fat.
Changing habitats may have encouraged foraging in more areas, expanding the number of ridgetops and valleys visited by hunting and gathering parties. as people moved into areas formerly unoccupied, family groups may have become more isolated. Interaction between groups may have been blocked by evolving religious or political barriers, and the emergence of separate languages.
Finding different designs in different locations that were occupied at the same time period suggests that the occupants of those two places were isolated by physical or cultural barriers, allowing time for flintknappers in different groups to evolve separate styles. For example, access to the Thunderbird quarry may have been limited by new boundaries between foraging groups that emerged about 10,000 years ago. That constraint could have spurred a hunting band to use chert from Back Creek, north of modern-day Winchester.
A workshop location where chert was reduced to cores and some finished points, later labeled the Fout Site, was destroyed when the Virginia Department of Transportation expanded US 522. The site was excavated by archeologists before the highway bridge over the creek was built, though the information from the 1969 dig was not finally published until 1996.28

The presence of a significantly new stone tool or pottery design in a location could also suggest human migration. New designs may appear quickly, without gradual changes in the preceding design, when a place is occupied by a new group. Immigrants bring new cultural patterns.
By tracing the locations of archeological sites with a specific design, it is possible to show the migration paths of the past. In the Paleo-Indian Period, groups interacted often enough to have a standard way of making Clovis, Dalton, and Cumberland points across all of Virginia.
In the Archaic Period, the Native American population expanded. Greater diversity in point styles suggests that boundaries between different groups of people became more firm, limiting long-distance travel of individual hunting/gathering bands. New points were smaller and had many with notches on the corner, where sinew and plant fibers were wrapped to attach the point to a smaller spear or an atl-atl projectile.
