Clovis culture

• 1. Introduction

  ›

  Clovis culture is the name archaeologists give to some of the earliest well-documented people in the Americas, hunter-gatherers who lived roughly 13,050 to 12,750 years before the present. They left behind a distinctive toolkit so recognizable that a single type of stone point bears the name of a town in New Mexico where their remains were first properly excavated.

  In 1929, a nineteen-year-old named Ridgely Whiteman found that site near Blackwater Draw in eastern New Mexico, having followed the nearby Folsom excavations closely in the newspapers. What he and later researchers uncovered there opened a debate that still runs today: who exactly were the Clovis people, where did they come from, and what role did they play in the disappearance of the great beasts they hunted? Those questions will unfold across this documentary. One clue to the answers lies buried in Montana, in the grave of a young boy whose bones carry genetic echoes reaching back to Siberia and forward to Indigenous peoples across the Americas.

• 2. Discovery and Excavation

  ›

  On the 29th of August 1927, the first evidence of Pleistocene humans seen simultaneously by multiple archaeologists in the Americas came to light near Folsom, New Mexico. Researchers found a Folsom point lying in place with the bones of the extinct bison species Bison antiquus. That confirmation set off a search for other ancient human traces across the continent.

  Whiteman's 1929 find near Blackwater Draw, the locality that would become the Clovis type site, drew serious professional attention within a few years. The most rigorous excavation work at Blackwater Draw happened between 1932 and 1937. Edgar Billings Howard led a crew there until 1935, and John L. Cotter of the Academy of Natural Sciences at the University of Pennsylvania continued afterward.

  Howard's crew had actually begun their work at Burnet Cave, the first professionally excavated Clovis site, departing in August 1932 to visit Whiteman's site. By November of that year, Howard was back at Blackwater Draw investigating finds that had turned up during a nearby construction project. The American Journal of Archaeology noted Howard's Burnet Cave work in its January-March 1932 edition, including the discovery of extinct fauna and a point of the Folsom type found four feet below a Basketmaker burial.

  There is a small irony in the naming. The Dent site in Colorado held the first known association of Clovis points with mammoth bones. Researcher Gary Haynes has argued, citing Hannah Marie Wormington's book Ancient Man in North America, that the distinctive fluted point style eventually linked to megafauna at over a dozen North American sites might more accurately have been called the "Dent" point rather than the Clovis point. The town of Clovis simply got there first in the historical record.

• 3. The Points and the Tools

  ›

  A Clovis point is a bifacial projectile point, meaning flakes were removed from both of its faces, and it is typically fluted on both sides. That fluting, an elongate flake removed from the base, runs up roughly a third to a half of the point's length. This distinguishes Clovis points from many later Paleoindian traditions, where the flute runs the full length.

  The largest Clovis points exceed ten centimeters. They were produced from nodules or siliceous cryptocrystalline rocks, shaped first through percussion flaking and finished with pressure flaking. The fluting process was risky: points frequently broke during that stage. Some researchers believe the flute acted as a shock absorber during impact, redistributing stress; others have proposed it was purely stylistic or helped secure the point to a spear handle.

  Wear patterns show that these points did far more than tip a spear. They also functioned as cutting and slicing tools, and some researchers have argued that certain types were used primarily as knives. Clovis people may have carried these tools as thrusting spears, throwing weapons, or possibly ground-mounted pikes, and may have used them with a spear-thrower.

  Beyond the points, Clovis blade technology belongs to the broader global Upper Paleolithic tradition. Blades were twice as long as they were wide, struck from specially prepared conical or wedge-shaped cores, and then modified into endscrapers for working hides, serrated tools, and gravers. Unlike the bifaces, blade cores were apparently not carried over long distances; people transported the blades themselves in their mobile kits.

  Bone tools round out the picture. Rods made from bone, antler, and ivory appear at Clovis sites, some beveled on both ends (interpreted most often as foreshafts for stone points) and some beveled on one end with the other end coming to a point (interpreted as projectile points themselves). Adzes, likely used for woodworking, are also part of the toolkit. At the Clovis-associated La Prele site in Wyoming, bone needles made from jackrabbit, red fox, and feline bone suggest that Clovis people were stitching clothes from the pelts of at least those species, which likely included bobcat, Canada lynx, cougar, or American cheetah.

• 4. How They Lived

  ›

  Archaeologists describe Clovis hunter-gatherers as "high-technology foragers", a phrase that captures how sophisticated their resource strategies were despite relying on stone and bone rather than metal. Stone tools found at many Clovis localities were made from rock sources hundreds of kilometers away; in one case, the source was more than 900 kilometers distant.

  Mobility was central to Clovis life, though the patterns varied by region. In the Southern Plains, camps tended to be large and positioned on the edges of the region near sources of workable stone, and groups appear to have migrated seasonally into the plains to hunt megafauna. In the southeast, large camps may have served as staging areas where multiple bands gathered on a seasonal basis, possibly for social occasions as well as practical ones.

  At Jake Bluff in northern Oklahoma, Clovis points appear alongside the butchered bones of at least 22 individual Bison antiquus. The site, at the time of that kill, was a steep-sided arroyo with a dead end. The geography suggests that hunters drove the herd into the channel and trapped them before killing them.

  Proboscideans, primarily Columbian mammoths, are the most commonly recorded large animals in Clovis sites, followed by bison. But the diet was broader. Jackrabbits appear at around 31% of all Clovis sites, and the range of species possibly targeted includes caribou, peccaries, ground sloths, glyptodonts, tapirs, camels, and llamas. Plant remains, found almost exclusively at eastern North American sites, consist mainly of easily gathered fruit with little evidence of processing tools.

  Isotope analysis of the young boy Anzick-1, the only known Clovis burial, suggests that mammoths made up approximately 35-40% of the diet for his group. Elk and probably bison also contributed substantially, while small animals accounted for only around 4%.

  Over twenty artifact caches have been identified across North America. These deliberate deposits, typically of stone tools including points and bifaces, were presumably left for later retrieval. Some researchers have interpreted certain caches as ritual rather than purely practical deposits. The Clovis culture is also among the few Paleoindian cultures known to have used red ochre for artistic and ritual purposes, including covering objects in caches and use in burials. Limestone nodules with incised geometric patterns, some imitating leaf shapes, found at the Gault site in Texas, are the best-known examples of what may be creative expression in the Clovis record.

• 5. The Overkill Question

  ›

  Beginning in the 1950s, Paul S. Martin developed what he called the "overkill hypothesis": that human hunters, including Clovis people, drove the Late Pleistocene megafauna extinctions in North America. The logic extended beyond direct hunting. The loss of large herbivores, Martin argued, would have cascaded through the ecosystem to bring down large carnivores as well.

  The question has never been settled cleanly. The timing of megafauna extinctions in North America overlaps with major climatic shifts at the end of the Pleistocene, making it genuinely hard to separate human impact from environmental change. A 2012 survey published in The SAA Archaeological Record found that 63% of responding archaeologists believed the extinctions were most likely the result of a combination of factors.

  The end of the Clovis culture itself, around 12,750-12,600 years before the present, may be connected to the same megafaunal decline. As the large animals became scarcer, the argument goes, Clovis groups became less mobile and more regionally rooted, which in turn encouraged local differentiation in toolmaking and culture. There is no evidence that this transition involved a population collapse; the shift is generally read as normal cultural change rather than catastrophe.

  The Folsom tradition in central North America followed Clovis, along with the Cumberland point in mid and southern North America, the Suwannee and Simpson points in the southeast, and Gainey points in the Northeast-Great Lakes region. The Clovis and Folsom traditions may have coexisted for somewhere between 80 and 400 years.

• 6. The Boy from Montana

  ›

  Near Wilsall, Montana, in 1968, a young boy's remains were found in a burial site. He is known as Anzick-1 and is the only human burial directly associated with Clovis culture tools. More than 100 stone and bone artifacts accompanied him, all stained with red ocher. His remains date to approximately 12,990-12,840 years before the present.

  Sequencing his genome placed him within a population ancestral to many contemporary Indigenous peoples of the Americas, with particularly close ties to groups from Central and South America. His relationship to contemporary North American Indigenous populations is less direct, though there is considerable variation. Older ancient South American remains tend to be genetically closer to Anzick-1, which suggests that distinct Native American populations had already diverged from one another by the time of the Clovis culture, before subsequent migrations reshaped the distribution of those groups during the Holocene.

  Anzick-1 also shares DNA with the Mal'ta boy from central Siberia, whose remains are approximately 24,000 years old. That connection confirms the Asian origin of the population that produced the Clovis culture. He belongs to Y chromosome Haplogroup Q-L54, which is common among contemporary Native Americans. His mitochondrial haplogroup, D4h3a, is rare among contemporary Native Americans, occurring in only 1.4% of the population, predominantly along the Pacific coast, but appears more frequently among the very earliest Indigenous Americans.

• 7. Before Clovis, After Clovis

  ›

  For much of the twentieth century, many researchers held to what they called the "Clovis First" model: the idea that Clovis represented not just the earliest recognizable archaeological culture in North America but the first human presence in the Americas south of the Laurentide ice sheet. That view has since been largely set aside.

  Several well-accepted sites predate the oldest Clovis evidence by at least a thousand years. Cooper's Ferry in Idaho is dated to approximately 15,800 years before the present. Paisley Caves in Oregon has dates of approximately 14,200 years BP. Monte Verde II in Chile reaches back to approximately 14,500 years BP. The White Sands footprints in New Mexico may push human presence in the Americas back even further, to around 23,000 years ago during the Last Glacial Maximum.

  The traditional explanation for how people arrived in the Americas south of the ice pointed to an "ice-free corridor" between the Laurentide and Cordilleran ice sheets. A 2022 study proposed that this corridor was impassable until around 13,800 years ago, well after the earliest confirmed human presence south of the ice. A Pacific coastal migration route is now considered more likely by many researchers.

  In western North America, the Clovis culture was contemporaneous with the Western Stemmed Tradition, which produced unfluted projectile points and continued in the region for several thousand years after the Clovis period ended. The origins of the Clovis fluted-point style appear to lie in temperate North America south of the Laurentide ice sheet rather than in Beringia, though the broader cultural tradition may have roots in the Dyuktai lithic style known from Beringia. Some researchers have also suggested that Clovis influenced tool traditions in South America, where the Fishtail or Fell point style was widespread at the same time that Clovis points were in use in North America, with the Fishtail style possibly derived from Clovis.
