This map shows the approximate location of the ice-free corridor and specific Paleoindian sites (Clovis theory).

It is not definitively known how or when the Native Americans first settled the Americas and the present-day United States. The prevailing theory proposes that people migrated from Eurasia across Beringia, a land bridge that connected Siberia to present-day Alaska during the Ice Age, and then spread southward throughout the Americas and possibly going as far south as the Antarctic peninsula. This migration may have begun as early as 30,000 years ago^[14] and continued through to about 10,000+ years ago, when the land bridge became submerged by the rising sea level caused by the ending of the last glacial period.^[15] These early inhabitants, called Paleoamericans, soon diversified into many hundreds of culturally distinct nations and tribes.
The pre-Columbian era incorporates all period subdivisions in the history and prehistory of the Americas before the appearance of significant European influences on the American continents, spanning the time of the original settlement in the Upper Paleolithic period to European colonization during the Early Modern period. While technically referring to the era before Christopher Columbus' voyages of 1492 to 1504, in practice the term usually includes the history of American indigenous cultures until they were conquered or significantly influenced by Europeans, even if this happened decades or even centuries after Columbus' initial landing.

Native development prior to European contact

The Cultural areas of pre-Columbian North America, according to Alfred Kroeber.

Native American cultures are not normally included in characterizations of advanced stone age cultures as "Neolithic," which is a category that more often includes only the cultures in Eurasia, Africa, and other regions. The archaeological periods used are the classifications of archaeological periods and cultures established in Gordon Willey and Philip Phillips' 1958 book Method and Theory in American Archaeology. They divided the archaeological record in the Americas into five phases;^[16] see Archaeology of the Americas.
The Clovis culture, a megafauna hunting culture, is primarily identified by use of fluted spear points. Artifacts from this culture were first excavated in 1932 near Clovis, New Mexico. 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, by which it was inserted into a shaft. 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. (roughly 9100 to 8850 BCE).
Numerous Paleoindian cultures occupied North America, with some arrayed around the Great Plains and Great Lakes of the modern United States and Canada, as well as adjacent areas to the West and Southwest. According to the oral histories of many of the indigenous peoples of the Americas, they have been living on this continent since their genesis, described by a wide range of traditional creation stories. Other tribes have stories that recount migrations across long tracts of land and a great river, believed to be the Mississippi River.^[17] Genetic and linguistic data connect the indigenous people of this continent with ancient northeast Asians. Archeological and linguistic data has enabled scholars to discover some of the migrations within the Americas.

A Folsom point for a spear.

The Folsom Tradition was characterized by use of Folsom points as projectile tips, and activities known from kill sites, where slaughter and butchering of bison took place. Folsom tools were left behind between 9000 BCE and 8000 BCE.^[18]
Na-Dené-speaking peoples entered North America starting around 8000 BCE, reaching the Pacific Northwest by 5000 BCE,^[19] and from there migrating along the Pacific Coast and into the interior. Linguists, anthropologists and archeologists believe their ancestors comprised a separate migration into North America, later than the first Paleo-Indians. They migrated into Alaska and northern Canada, south along the Pacific Coast, into the interior of Canada, and south to the Great Plains and the American Southwest.
They were the earliest ancestors of the Athabascan- speaking peoples, including the present-day and historical Navajo and Apache. They constructed large multi-family dwellings in their villages, which were used seasonally. People did not live there year-round, but for the summer to hunt and fish, and to gather food supplies for the winter.^[20] The Oshara Tradition people lived from 5500 BCE to 600 CE. They were part of the Southwestern Archaic Tradition centered in north-central New Mexico, the San Juan Basin, the Rio Grande Valley, southern Colorado, and southeastern Utah.
Since the 1990s, archeologists have explored and dated eleven Middle Archaic sites in present-day Louisiana and Florida at which early cultures built complexes with multiple earthwork mounds; they were societies of hunter-gatherers rather than the settled agriculturalists believed necessary according to the theory of Neolithic Revolution to sustain such large villages over long periods. The prime example is Watson Brake in northern Louisiana, whose 11-mound complex is dated to 3500 BCE, making it the oldest, dated site in the Americas for such complex construction. It is nearly 2,000 years older than the Poverty Point site. Construction of the mounds went on for 500 years until was abandoned about 2800 BCE, probably due to changing environmental conditions.^[21]
Poverty Point culture is a Late Archaic archaeological culture that inhabited the area of the lower Mississippi Valley and surrounding Gulf Coast. The culture thrived from 2200 BCE to 700 BCE, during the Late Archaic period.^[22] Evidence of this culture has been found at more than 100 sites, from the major complex at Poverty Point, Louisiana (a UNESCO World Heritage Site) across a 100-mile (160 km) range to the Jaketown Site near Belzoni, Mississippi.

Poverty Point is a 1 square mile (2.6 km²) complex of six major earthwork concentric rings, with additional platform mounds at the site. Artifacts show the people traded with other Native Americans located from Georgia to the Great Lakes region. This is one among numerous mound sites of complex indigenous cultures throughout the Mississippi and Ohio valleys. They were one of several succeeding cultures often referred to as mound builders.
The Woodland period of North American pre-Columbian cultures refers to the time period from roughly 1000 BCE to 1,000 CE in the eastern part of North America. The term "Woodland" was coined in the 1930s and refers to prehistoric sites dated between the Archaic period and the Mississippian cultures. The Hopewell tradition is the term for the common aspects of the Native American culture that flourished along rivers in the northeastern and midwestern United States from 200 BCE to 500 CE.^[23]
The indigenous peoples of the Pacific Northwest Coast were of many nations and tribal affiliations, each with distinctive cultural and political identities, but they shared certain beliefs, traditions and practices, such as the centrality of salmon as a resource and spiritual symbol. Their gift-giving feast, potlatch, is a highly complex event where people gather in order to commemorate a special events. These events, such as, the raising of a Totem pole or the appointment or election of a new chief. The most famous artistic feature of the culture is the Totem pole, with carvings of animals and other characters to commemorate cultural beliefs, legends, and notable events.
The Hopewell tradition was not a single culture or society, but a widely dispersed set of related populations, who were connected by a common network of trade routes,^[24] known as the Hopewell Exchange System. At its greatest extent, the Hopewell exchange system ran from the Southeastern United States into the southeastern Canadian shores of Lake Ontario. Within this area, societies participated in a high degree of exchange; most activity was conducted along the waterways that served as their major transportation routes. The Hopewell exchange system traded materials from all over the United States.
