The Serpent's Jaws: How Ancient Hunters Returned to the Sacred Earthwork

The sun is sinking low over the Ohio Valley, casting long shadows across the ridgetop. A line of hunters emerges from the treeline, weary but triumphant. Across their shoulders, a deer is lashed to a carrying pole. In their hands, bundles of wild turkey and rabbit. They have been gone for three days.

Ahead of them, winding across the hilltop like a giant snake frozen in stone, lies the Great Serpent Mound—1,300 feet of earthen coils, jaws gaping wide, facing the dying sun. In the oval just before the serpent’s open mouth, a fire has already been laid. Tonight, the hunt will not end with a meal. It will end with an offering.

This is the scene that once played out on the ridges of southern Ohio, where ancient Native American hunters returned from the forest not just with food, but with a sacred duty. The serpent-shaped earthwork was no mere monument. It was a living spirit, a gateway between worlds, and the final destination of every successful hunt .

Let’s walk with those hunters as they approach the fire.

The Serpent on the Hill: A Monument Older Than You Think

First, let’s get our bearings. The Great Serpent Mound sits in Adams County, Ohio, about 73 miles east of Cincinnati. It’s the largest serpent effigy in the world—and when I say large, I mean it . If you stood at its tail and walked to the unhinged jaws at the other end, you’d cover nearly a quarter of a mile.

But here’s where it gets complicated. Who built it? When? For decades, archaeologists thought the Adena culture (1000 BCE–200 CE) built it. Then the Hopewell culture (100 BCE–500 CE) got the credit . Today, the leading theory points to the Fort Ancient culture (1000–1650 CE), who likely built or refurbished the mound around 1070 CE .

That’s over 900 years ago. For perspective: The Norman Conquest of England happened in 1066 CE. While William the Conqueror was crossing the English Channel, someone on the other side of the Atlantic was sculpting a giant snake out of dirt.

The mound’s dimensions are staggering:

Feature	Measurement
Total length	1,300–1,354 feet
Height	1–3 feet
Width	~20 feet
Head alignment	Faces the summer solstice sunset

But the most striking feature isn’t the serpent’s body—it’s the oval positioned between the serpent’s open jaws . Inside that oval, archaeologists found something remarkable: a stone altar, blackened and cracked from intense heat . And around that altar, evidence of countless fires, offerings, and rituals that spanned generations.

This wasn’t a burial mound. No human remains have ever been found inside the serpent itself . This was something else entirely—a temple made of earth, open to the sky, where the living met the spirits.

The Return: What Happened When Hunters Came Home

So what did that moment of return actually look like?

We don’t have eyewitness accounts from 1070 CE. But we have clues—buried in the earthworks, preserved in the traditions of living Native American tribes, and documented by the first Europeans who witnessed similar ceremonies.

When hunters returned from a successful hunt, they didn’t just walk into the village and start butchering meat. The hunt was dangerous. Taking an animal’s life required spiritual permission. And the first portion of the kill belonged not to the hunter, not to his family, but to the powers that made the hunt possible.

The journey to the serpent mound would have been a procession. The hunters, still in their hunting clothes—perhaps still wearing the blood of the kill—would walk in single file along the ridge. Behind them, younger men might carry the carcasses on poles. Women and children might follow with bundles of firewood, knowing what was coming next.

As they approached the serpent’s head, the mound itself would have seemed to come alive. The setting sun—if the hunt ended at dusk—would have aligned perfectly with the serpent’s open jaws, just as the builders intended . The oval altar would be waiting, empty and cold.

The ritual began with preparation. Fresh wood was laid on the altar stone. The hunters would purify themselves—perhaps with water from a nearby spring, perhaps with smoke from smoldering sage. And then, the offering.

The Altar Fires: Evidence from the Earth

We know these fires were real because the evidence is still in the ground. At the Turner Group of mounds in Ohio—a massive ceremonial complex associated with the Hopewell culture—archaeologists found something remarkable .

Under one large mound, they discovered a stone circle 100 feet in diameter. Inside that circle: a floor of burnt clay, packed hard. And resting on that floor: two altars.

Here’s what made them altars and not just hearths. On these stone platforms, thousands of objects had been deliberately burned. Treasures—copper ornaments, carved stone pipes, sheets of mica, shells from the Gulf Coast—all heaped onto the fire . After the fire died, the ashes weren’t scattered. Layers of clay and sand were laid over the entire mound. The site was sealed. Destroyed. Used once, then forever abandoned.

That’s not cooking. That’s sacrifice.

At another Turner mound, the builders positioned the structure to face east, aligned with the rising sun . This wasn’t accidental. Across the ancient world—from Egypt to Mesoamerica to the Ohio Valley—the sun’s path was the ultimate calendar, the heartbeat of agricultural and hunting seasons.

At the Great Serpent Mound itself, the oval altar points toward the rising sun . And the serpent’s jaws? They’re open to the summer solstice sunset . The longest day of the year. The peak of the growing season. The time when the world was most alive.

These were not primitive people guessing at the cosmos. These were master astronomers who encoded their knowledge in dirt and stone.

What Was Offered? The First Fruits of the Hunt

So what, exactly, went into that ritual fire?

Let’s start with what we know. The Hopewell and Fort Ancient peoples who built these earthworks were not struggling to survive. They were sophisticated farmers who grew corn, beans, and squash . They lived in permanent villages, often surrounded by wooden palisades . They hunted white-tailed deer, elk, black bear, wild turkey, and rabbit . They fished the Ohio River and its tributaries. They had plenty to eat.

So when they made an offering, they weren’t burning their last scrap of food. They were giving their best.

The first kill of a hunt would have been special. The largest deer, the fattest turkey, the most impressive bear—these were not ordinary meals. They were gifts to the spirits who had allowed the hunt to succeed.

Among the Shawnee, whose ancestral lands included Ohio, the Great Serpent was a powerful spirit that could grant success in hunting . Hunters would call upon the Serpent’s power before setting out. After a successful hunt, they would return thanks—often by offering a portion of the kill.

But the offerings weren’t limited to meat. Archaeologists have found:

Copper ornaments – traded from the Great Lakes region
Marine shell – brought up from the Gulf of Mexico
Mica – mined in the Appalachian mountains
Obsidian – from as far away as Yellowstone
Stone pipes – carved into animal shapes
Freshwater pearls – harvested from local mussels

These objects traveled hundreds, sometimes thousands, of miles to end up on those altars. They were the most valuable things these people owned. And they burned them.

That’s how important the ritual was.

The Serpent’s Meaning: Not a Monster, But a Relative

We need to talk about the serpent itself. In Western tradition, snakes are often villains—the tempter in Eden, the enemy of heroes. That’s not how Native Americans saw them.

To the tribes of the Ohio Valley—the Shawnee, the Miami, the Wyandotte—the Great Serpent was a powerful, ambivalent spirit . The Shawnee called it Msi Kinepikwa (“Great Snake”). The Miami called it Lenipinsia—a reference to the Underwater Panther, one of the serpent’s many forms . The Delaware called it Maxaxkuk, the “Huge Snake” .

This spirit could be dangerous. It could cause storms, floods, illness. But it could also grant power—the power to heal the sick, the power to hunt successfully, the power to find copper and shells (which were thought to be the serpent’s scales) .

So when hunters approached the serpent mound, they weren’t approaching a monument to a defeated enemy. They were approaching a living relative, a powerful older brother, who had the power to give or withhold.

The offering in the fire was not a bribe. It was a gift between kin.

The Mississippian Connection: A Serpent Shared

Here’s a fascinating thread that connects Ohio to the rest of North America.

The Fort Ancient culture, which likely built or refurbished the Great Serpent Mound around 1070 CE, was heavily influenced by the Mississippian culture centered at Cahokia, near modern-day St. Louis . Cahokia was the largest pre-Columbian city north of Mexico, with a population of perhaps 20,000 people at its peak.

And what symbol did the Mississippians use extensively? The rattlesnake .

Mississippian artists carved serpent motifs onto shell gorgets (chest ornaments), engraved them onto copper plates, and painted them onto pottery. The serpent was a common theme in their religious art—often depicted with a rattlesnake’s tail, curled into spirals, mouths open wide.

The Fort Ancient people, living hundreds of miles to the east, adopted this symbol and transformed it into something uniquely their own. The Great Serpent Mound doesn’t have a rattle—so it’s not specifically a rattlesnake—but the influence is clear .

This wasn’t cultural isolation. This was a network of shared beliefs, stretching from the Gulf of Mexico to the Great Lakes, all connected by rivers and trade routes and a shared understanding of the serpent’s power.

The Wider Context: Serpents Across the Woodlands

Ohio wasn’t the only place where serpent effigies rose from the earth. Similar earthworks have been found across the Midwest :

Adams County, Illinois – A serpent effigy about 1,500 feet long, conformed to the shape of a natural bluff
Wisconsin – Serpent effigies at Mayville, Green Lake, Madison, and Potosi
Dakota Territory – A serpent formed from standing stones, described by 19th-century explorers
Stubbs Earthworks, Ohio – A Hopewell site once thought to contain another serpent effigy, though this interpretation is now debated

The Stubbs Earthworks (also known as the Bigfoot Earthworks or Warren County Serpent Mound) was a massive Hopewell ceremonial center dating to 100 BCE–500 CE . It covered a large area with circular and rectangular enclosures, timber circles, and a W-shaped earthwork that some early archaeologists interpreted as a snake.

But none compare to the Adams County serpent. It is, and likely always will be, the largest serpent effigy on the planet.

The Ritual Fire: More Than Just Burning Meat

Let’s circle back to that fire. Why burn food? Why destroy valuable objects? Why go to all that trouble?

To understand, you have to shift your thinking about what an offering is.

In the Native American worldview of the Eastern Woodlands, the world was filled with spiritual powers—in the animals, in the plants, in the rivers, in the sky. These powers were not distant abstractions. They were present, active, and involved in human life.

When a hunter killed a deer, he had taken something that belonged to the Deer People. The deer’s spirit had to be honored. The first meat had to be given back. If you didn’t, next time the deer would hide. Your arrows would miss. Your children would go hungry.

The fire was a messenger. Smoke rises. Spirits dwell in the sky. By placing the offering in the fire, the hunters were sending it upward, transforming it from physical food into spiritual food.

This is why the mounds faced the sun . The sun was the most visible spirit of all—rising and setting in an endless cycle that marked the seasons, governed the crops, and lit the path of every hunt. An offering made at sunset, with the serpent’s jaws open to the dying light, was an offering made at the threshold between day and night, between the world of the living and the world of the spirits.

A professor who studied the Turner mounds in the 19th century described them as having been used for “religious rites” . After a great festival, the mounds were sealed with layers of clay and sand, “and its use forever destroyed” . This wasn’t a recycling program. This was a final act—a ceremonial burial of the sacred space itself.

Putting It All Together: A Night at the Serpent

Let’s return to that dusk scene with everything we’ve learned.

The hunters have walked miles to reach the serpent. They are tired, but they are also transformed. They have succeeded where others might have failed. They have taken life, and now they must give something back.

The earthwork coils before them, 1,300 feet of earthen muscle, jaws open to the setting sun. The builders who shaped this mound knew exactly what they were doing. Every curve, every angle, every alignment with the sun and stars was intentional. This was not a random pile of dirt. This was scripture written in soil.

The oval altar sits between the serpent’s jaws. The fire is lit. The first portion of the kill—perhaps the deer’s heart, perhaps the choicest cut of meat—is placed on the flames. Maybe a copper pendant follows. Maybe a carved pipe. Maybe a handful of shell beads from the distant Gulf.

The smoke rises. The hunters watch it climb. Some might sing. Some might pray in silence. Some might simply breathe, knowing that the offering has been received.

And then? The hunt is complete. Not when the animal fell, but when the fire died. The hunters can return to their village. They can eat. They can share the remaining meat with their families. The spirits are satisfied. The world is balanced again.

For another season, at least.

Conclusion: The Serpent Still Waits

The Great Serpent Mound still exists. You can visit it today. Walk along its coils. Stand at its jaws. Face the sunset on the summer solstice and see exactly what those ancient hunters saw nearly a thousand years ago.

The altar is still there, though the fires have long gone cold. The serpent’s body still winds across the ridge, though the hunters who once processed along its length have turned to dust.

But the offering—the act of giving back, of honoring the kill, of recognizing that hunting is not just taking but also receiving—that tradition hasn’t disappeared. It survives in the ceremonies of living Native American tribes, in the quiet prayers of modern hunters who still thank the animal before field-dressing it, in the knowledge that we are not the only beings in this world with souls.

The serpent’s jaws are still open. The sun still sets. And somewhere, if you listen closely, you can almost hear the footsteps of hunters approaching the fire.
