Buluksée: The Water Beast of the Yellowstone River

In 1986, Apsáalooke elder Grant Bulltail saw something near Pryor Creek, Montana, that he had always believed belonged to the stories of his ancestors.

It was a creature known as Buluksée, a mysterious dinosaur-type water beast whose name had survived in Crow oral traditions for generations. Bulltail had grown up hearing about these animals, including accounts of warriors who encountered them along the Yellowstone River. But hearing a story passed down through generations was one thing. Seeing what he believed to be the same creature with his own eyes was something entirely different.

According to the Native Memory Project, Bulltail and members of his family encountered the animal near a secluded stretch of Pryor Creek. In a conversation that was not recorded, he described seeing a creature resembling a small dinosaur standing in the road beside an area of still water, its back turned toward their vehicle. When he stopped to watch, approximately ten smaller creatures scurried across the road in front of them.

The possibility that the smaller animals were its young made the encounter even more remarkable.

Bulltail believed these creatures inhabited the secluded creek bottoms, where steep banks and thick vegetation offered places to remain hidden. He also suspected they laid their eggs on land, despite spending much of their lives in the water.

He later drew a sketch of the animal he remembered seeing, preserving an image of a creature that had previously existed for him primarily through the stories of his people.

Was it an unfamiliar animal? A case of mistaken identity? Or something that has yet to be explained?

There is no independently verified zoological evidence establishing the existence of Buluksée, but Bulltail’s account raises an interesting question about the relationship between traditional stories and personal experience.

What happens when someone who has inherited a legend believes he has encountered the creature himself?

For Bulltail, the experience connected the present to a much older world, one in which the rivers of Montana were said to conceal beings capable of challenging even the strongest warriors.

And the Yellowstone River was one of the places where those creatures were feared.

What Was Buluksée?

One of the difficulties in researching legendary creatures is separating their original descriptions from the details added by later storytellers. A mysterious animal may begin as something described in a particular cultural tradition, only to acquire the appearance of a familiar monster as its story spreads.

Buluksée presents an especially interesting example because the surviving Apsáalooke accounts distinguish it from other extraordinary water creatures.

The Native Memory Project, which preserves stories shared by Grant Bulltail, describes Buluksée as a relatively small water beast, approximately five to six feet long. Its general appearance is compared to a hadrosaur, a type of plant-eating dinosaur often illustrated with a heavy body, powerful hind legs, and a long tail.

That comparison offers a rough impression of the animal’s reported shape, although it shouldn’t be mistaken for a scientifically established identification. Bulltail sometimes referred to the creatures as dinosaurs, but the accounts do not provide enough anatomical detail to determine what he saw.

What they do suggest is an animal capable of moving between water and land. Buluksée was associated with rivers and creeks, particularly secluded stretches where vegetation concealed the banks. Bulltail believed the creatures could reproduce on land, and his reported encounter with several smaller animals reinforced that impression.

The accounts also portray Buluksée as dangerous. It could seize a horse or human and drag its victim beneath the surface, using the water to overcome someone who might have been difficult to defeat on land.

But Buluksée wasn’t the only mysterious aquatic being remembered in Crow traditions.

Bulltail also described a creature called bimmuummaakoole, a name translated as “lives in the water.” This animal was considerably larger and possessed a long neck, giving it an appearance compared to the famous Loch Ness Monster.

The distinction matters.

Modern cryptid enthusiasts often group reports of unexplained water creatures together, imagining enormous prehistoric animals surviving in remote lakes and rivers. Yet Bulltail’s accounts preserve separate identities for these beings. Buluksée was smaller and apparently capable of moving on land, while bimmuummaakoole was described as a much larger, long-necked aquatic creature.

The names themselves offer another glimpse into the age of these traditions. According to Bulltail, the meaning of Buluksée had been lost over time, even though the creature remained part of Apsáalooke storytelling.

Its name also survived in the names of warriors.

Bulltail explained that a Crow warrior known in English as Alligator Stands Up, who participated in the Battle of the Rosebud in 1876, had a name connected to Buluksée. The English rendering was a mistranslation rather than a reference to the familiar alligator.

I find that detail fascinating. Names can preserve traces of cultural knowledge long after outsiders have lost the context needed to understand them. A creature might seem unfamiliar to someone encountering its story today, yet its name once carried enough significance to become part of a warrior’s identity.

And in one account from the Yellowstone River, the danger associated with that name becomes painfully clear.

The Warrior Taken by the River

During the nineteenth century, an Apsáalooke war party was traveling through Yellowstone River country when one of its young warriors stopped to water his horse.

The Yellowstone River was an important part of the landscape through which the Crow traveled. Its waters provided resources and shaped the valleys, but the river could also be unpredictable. Deep channels and powerful currents made crossing dangerous, particularly when horses were involved.

According to the account preserved by Grant Bulltail, the young warrior brought his horse to the water’s edge, unaware that something was waiting beneath the surface.

Without warning, a creature rose from the river and seized the horse by its nose.

The animal struggled as the beast pulled it toward deeper water. Before the rider could escape, the creature caught him by the ankle, dragging him into the current as well.

Two of the warrior’s companions rushed to help.

Both possessed extraordinary spiritual powers. One was associated with the energy of a large wasp, while the other carried the power of a dragonfly. Within the Apsáalooke spiritual traditions reflected in these stories, such powers could provide abilities beyond those available through ordinary physical strength.

But neither man could overcome the creature.

Despite their efforts, the young warrior and his horse were drawn into a whirlpool and disappeared beneath the river.

I find the suddenness of that encounter especially disturbing. There was no warning that an ordinary moment beside the water would become a desperate struggle. The young man’s companions had little time to react, and even the spiritual powers they relied upon could not save him.

The river simply swallowed him.

His companions, however, weren’t prepared to abandon all hope.

They sought the help of a medicine man named Fringe, a man whose reputation for extraordinary healing was connected to his own encounters with powerful water beings.

The Powers of Fringe

Fringe was a renowned Apsáalooke medicine man whose story was preserved by Grant Bulltail.

According to the account, Fringe had sought spiritual power from creatures inhabiting the waterways of what is now Wyoming. During the 1850s, he fasted near the meeting of the North and South Forks of the Shoshone River, where a black water beast with a long neck was believed to live.

He hoped to receive some of the creature’s power, but his efforts there were unsuccessful.

Eventually, he traveled to the hot springs near present-day Thermopolis, where another extraordinary aquatic being was said to reside. This creature possessed the ability to live beneath the water and move across its surface, and Fringe sought a spiritual relationship with it.

This time, he succeeded.

Through that encounter, Fringe received powers associated with healing. According to Bulltail’s account, he became capable of curing people by taking them into water and drawing upon the abilities he had acquired.

His reputation explains why the companions of the missing warrior turned to him.

They had already witnessed the failure of two powerful men to rescue their friend. If anyone could reach the young man beneath the river, they hoped it would be Fringe.

But the medicine man understood that even his abilities had limits.

He explained that he had only four days in which to bring the warrior back alive.

The time restriction introduces a troubling uncertainty. The young man’s companions had watched him disappear into a whirlpool, and there was no guarantee that he had survived. Yet Fringe was willing to attempt what ordinary people could not.

He traveled to the junction of the Bighorn and Yellowstone Rivers, where the water beast was believed to live.

There, according to the story, he encountered the creature along with an enormous snapping turtle associated with it.

The presence of the turtle suggests a hidden aquatic world inhabited by more than one extraordinary being. Unfortunately, the surviving account offers little additional physical description of the turtle or its relationship to Buluksée.

Fringe nevertheless accomplished something remarkable.

He recovered the young warrior’s body from the water.

But he could not restore his life.

The ending is striking because the medicine man succeeds in reaching the place where the warrior was lost, yet the one thing everyone desperately wants remains beyond his power.

Bulltail’s family connection to the account makes it even more compelling. He explained that his great-grandfather had been present on the riverbank during the attempt to recover the warrior. Although the man could not see much from his position behind the crowd, the events became part of the family history passed down through later generations.

The story wasn’t simply an anonymous tale of a monster beneath the river. It was connected to people whose names and experiences remained important within Bulltail’s family.

And it wasn’t the only account of a human confronting Buluksée.

The Warrior Who Fought Back

Another Apsáalooke story preserved by Bulltail concerns a man known as Wants to Die, also called Plain Bull.

Plain Bull had been wounded in the hip during fighting in 1876, leaving him with a lasting physical impairment. Yet his injury did not diminish the spiritual power he possessed. According to the account, he encountered a Buluksée near Pryor Creek, not far from the location where Bulltail would report seeing one more than a century later.

The creature seized Plain Bull and attempted to drag him into the water.

But unlike the young warrior taken from the Yellowstone River, Plain Bull possessed the means to resist. Drawing upon powerful buffalo energy, he fought the beast and managed to drag it from the creek onto dry land. He hauled it up the bank and rolled it onto its back, leaving the creature helpless.

The image is remarkable. A man carrying a serious injury overcomes a water beast by forcing it out of the environment where it holds the advantage.

Yet Plain Bull did not kill the creature.

According to the account, he released it receiving an assurance that it would no longer trouble the people.

That ending introduces a different relationship between human beings and the mysterious creatures inhabiting their world.

The young warrior’s companions had been unable to prevent a tragedy, while Plain Bull succeeded through spiritual power associated with the buffalo. But his victory did not require destroying the animal. Once the immediate danger had passed, the creature was allowed to return to the water.

It’s tempting to interpret these stories simply as examples of courage overcoming fear, but I think that misses something important. The Apsáalooke accounts describe a world in which people could receive power through relationships with other beings, and where the outcome of an encounter depended upon more than physical strength.

The creatures themselves were dangerous, but the stories didn’t always portray them as enemies that had to be destroyed.

Sometimes survival depended upon understanding how to confront them.

A Mystery Along Pryor Creek

That brings us back to Grant Bulltail’s reported encounter in 1986.

Pryor Creek winds through south-central Montana, eventually joining the Yellowstone River near Huntley. In some areas, the creek passes between steep banks thick with vegetation, creating secluded stretches where the water is difficult to observe from above.

Bulltail believed these conditions provided an ideal habitat for Buluksée.

He also reported that cattle had disappeared in the area, although such losses cannot independently establish that an unknown animal was responsible. The combination of inaccessible banks and murky water nevertheless contributed to his belief that the creatures could remain concealed.

His own reported sighting was particularly significant because he believed he had seen not just one animal but evidence of a breeding population.

The Native Memory Project preserves Bulltail’s account and a drawing he made of the creature. The project also notes that the detailed description of the animal standing in the road, with several smaller creatures crossing in front of his vehicle, came from an unrecorded conversation.

That distinction matters. The drawing and recorded material provide evidence of what Bulltail reported, but they do not independently verify the animal’s existence or establish its identity.

Still, I find myself wondering what it must have felt like for him to see something he associated with stories passed down through generations.

Bulltail had spent much of his life preserving Apsáalooke oral traditions, many of which he learned from his grandfather, Comes Up Red. His work eventually earned him a National Heritage Fellowship from the National Endowment for the Arts in 2019.

He understood that these stories were part of his people’s cultural inheritance, not simply entertainment about frightening creatures.

And when he believed he encountered Buluksée near Pryor Creek, that inheritance became something he could connect to a personal experience.

Whether his sighting can ever be explained is another question.

What we can say is that the story did not disappear with the nineteenth-century warriors who encountered the creature in earlier accounts. It continued into the modern world through someone who knew those traditions intimately.

What Lies Beneath the Current

The Yellowstone River remains one of the great waterways of the American West, flowing from Yellowstone National Park through Montana and into North Dakota before joining the Missouri River.

Unlike many major rivers, the Yellowstone has no main-stem dams interrupting its course. Its waters continue to move through a landscape shaped by mountains and open plains, connecting places whose histories extend far beyond the establishment of the national park.

During our recent travels through Yellowstone country, I was struck by how much of the landscape seemed to extend beyond anything a photograph could capture. Yellowstone Lake left the strongest impression on me, but learning about the creatures associated with the river has added another dimension to my memories of the region.

I hadn’t heard of Buluksée when we made that trip. I certainly didn’t know about Grant Bulltail’s reported encounter near Pryor Creek or the older accounts of warriors struggling against creatures beneath the Yellowstone River.

What interests me now is how differently those stories approach the same mysterious being.

In one, Buluksée is an overwhelming force that takes a young man’s life despite the efforts of his companions. In another, a wounded warrior draws upon spiritual power to defeat the creature and then allows it to live. And in the modern account, a respected storyteller encounters what he believes to be the same animal, connecting the stories of his ancestors to something he experienced himself.

The accounts don’t offer a single explanation for the creature or its place in the world.

Perhaps that’s part of what makes them so fascinating.

There is no verified scientific evidence that Buluksée exists as an undiscovered species, and the comparison to prehistoric animals remains an interpretation rather than an identification. But the stories preserve something beyond the question of whether a mysterious animal might still inhabit Montana’s waterways.

They preserve the memories of people who confronted danger, the spiritual relationships they believed could help them survive, and the extraordinary beings associated with places they knew.

I keep returning to Bulltail’s experience near Pryor Creek. He had spent years listening to and preserving stories about creatures he believed belonged to the past, only to report an encounter that challenged that assumption.

Whether the animal he saw was something familiar viewed under unusual circumstances or a mystery that remains unresolved, his account became another chapter in a tradition that had already survived for generations.

And perhaps that is the most intriguing part of Buluksée’s story.

The creature may never be identified to the satisfaction of modern science. Its appearance may remain uncertain, and the accounts of its encounters may continue to invite different interpretations.

But the stories themselves have endured, carried from one generation to another along the waterways of Crow country.

Some mysteries survive because no one has found an answer.

Others survive because people continue to remember.
