A Snapshot From The Ice Age

Tucked into the windswept plains of eastern Wyoming lies one of North America’s most revealing archaeological sites: the La Prele Mammoth Site. First discovered in the 1980s, this Pleistocene-era site has delivered a steady stream of discoveries, from Clovis stone tools to delicate bone needles and the oldest known bead in the Americas.
Discovery And Rediscovery

Initially found in 1986 by avocational collectors, the site was partially excavated in the late 80s but then largely dismissed. Excavations resumed in 2014, eventually revealing just how large and significant the site truly was. More than 4,500 square meters have now been explored.
Dating Debates

Initial dating attempts were flawed due to contamination. Newer radiocarbon techniques corrected those errors. The site is now firmly dated to just under 13,000 years ago.
Red Ochre Everywhere

One of the excavation areas was saturated in red ochre, which is a natural clay used symbolically by Clovis and other ancient cultures. This reddish hue marked the center of what researchers believe was an ancient house.
The Oldest Bead In The Americas

The groundbreaking discovery of a seven-millimeter-long bone bead stunned archaeologists. Made from the bone of a prehistoric hare, it dates to about 12,940 years ago. It's the oldest confirmed bead ever found in North or South America.
An Unexpected Material

Historians were a bit surprised that the bead was made from a hare’s limb bone, instead of from large game like mammoths or bison. This is the first secure evidence that Clovis foragers hunted and utilized hares.
Microscopic Confirmation

Researchers used micro-CT scans and mass spectrometry to determine the bead's origin. The analysis confirmed that it had been deliberately shaped, with smoothed ends and fine grooves. The tests also eliminated the possibility that it had passed through a predator's digestive system.
A Site Deep Underground

Artifacts at La Prele are buried 10 to 12 feet below the surface, requiring intense excavation. These depths help preserve the site but also make it labor-intensive to study. Each season, new discoveries emerge from beneath ancient sediment layers.
A Delicate Discovery

The bead was discovered during the careful sifting of red-stained dirt through a mesh screen. Its polish and hollow shape gave it away as something extraordinary. Once cleaned, it became clear that it was not just a bone fragment, but a crafted object.
Bone Needles Galore

Excavations also uncovered 32 fragments of bone needles, a rare find from this era. They were likely used to stitch clothing from animal pelts. Their existence speaks to the complexity of Ice Age life, where survival meant making warm, fitted garments.
Unusual Bone Sources

The needles were crafted from the bones of small carnivores, including red foxes, bobcats, lynxes, and the extinct American cheetah. Using these fine bones made the needles easier to carve and more durable. It also suggests that Clovis people actively trapped animals for more than just meat.
The Mammoth Timeline

Radiocarbon dating has placed the mammoth remains at around 12,941 years ago. Earlier samples were contaminated, but newer dating confirms this critical period in North American prehistory. This date puts La Prele squarely in the terminal Pleistocene epoch.
Human Touch, Not Predator

One debate was whether the mammoth was killed or scavenged. Evidence of butchering and proximity of tools now strongly support human involvement. The site is now accepted as a Clovis-era kill and camp site.
Hundreds Of Artifacts

To date, more than 1,700 stone tools and flakes have been uncovered at La Prele. These include knives, scrapers, and projectile point fragments. Some tools show microscopic wear from butchering, hide scraping, and other daily tasks.
Clovis Point Fragment

Among the most exciting finds was the distal end of a Clovis point, which is a spear tip used for hunting. While a complete Clovis point remains elusive, even fragments are incredibly rare and valuable.
A Cultural Landmark

The site offers a rare snapshot of a month in the life of a Clovis hunting group. From kill site to campsite, La Prele has it all: meat processing, clothing repair, and ornament crafting. Such comprehensive sites are exceptionally rare in North American archaeology.
A Difficult Dig

Excavating La Prele is challenging due to the site's depth and soil density. Each layer must be meticulously removed and screened. But the rewards, like the oldest bead in the Americas, are more than worth it.
Ochre From Afar

Geochemical analysis shows the red ochre at La Prele came from the Powars II quarry, 100 kilometers (62 miles) away. This indicates long-distance transport of symbolic materials. Clovis groups were highly mobile and maintained widespread trade networks.
Temporary But Complex Homes

Structures at the site weren’t permanent houses but temporary shelters. Still, the presence of house floors, hearths, and clustered artifacts points to domestic life.
Tailored Clothing Evidence

The bone needles found suggest the production of warm, tailored clothing. This included fur trim and specific cuts, important in cold climates. And clothing was not just practical but possibly decorative.
Bones From Small Carnivores

Needles made from small carnivores may have been preferred for their shape and density. Fine limb bones allowed for precise shaping. This was a deliberate choice, rather than just using whatever was nearby.
Household Chores

Different areas of the site served different purposes: butchering, sleeping, crafting. Such spatial organization hints at planning and social structure. It also suggests Clovis people at La Prele weren’t warriors passing through, they were families surviving and creating. That domestic picture changes how we see ancient hunter-gatherers.
Long-Term Study

Excavations at La Prele have spanned decades, with more to come. One final field season is planned to explore a promising new cluster. Archaeologists hope for a complete Clovis point, or even more ornaments.
More Than Mammoths

La Prele reminds us that Clovis people didn’t just hunt megafauna. They used hares, foxes, cats, and more. Their diets and technologies were broader than previously assumed.
Beads As Status Symbols

Beads likely served as personal ornaments, maybe indicating status or group identity. Finding one shows that Clovis people had symbolic culture. It wasn’t just about survival, they valued beauty and meaning.
Tiny But Mighty

Before La Prele, bead-making was assumed but never proven in Clovis sites. This one artifact changes that narrative, and fills a major gap in North American archaeological records. It also provides a concrete link between Old and New World bead-making traditions.
Future Work

Ongoing studies will examine site layout, family life, and seasonal movements. Researchers want to know how these people lived day to day.
A Site Like Pompeii

La Prele is unique because it’s not just where a mammoth died. It’s where people lived, worked, and expressed themselves. One archaeologist compared La Prele to Pompeii, calling it a pristine record of Clovis life. That’s extremely rare in open-air North American sites. It’s a frozen moment from 13,000 years ago.
Global Significance

La Prele isn’t just important for American archaeology, it matters globally. It contributes to our understanding of human migration, culture, and technology. The Clovis bead, in particular, connects continents and time periods.
Rare Among Rarities

Sites like La Prele are one in a million. Beads like the one discovered are even rarer. Together, they make La Prele a crown jewel in American prehistory.
