She was just a number to the researchers. 399. That’s it. But to anyone who ever stood on the shoulder of a dusty road in Grand Teton National Park, she was something else entirely. She was the Queen of the Tetons.
It’s hard to explain the magnetism she had. Most grizzly bears are ghosts. They live in the shadows of the high country, avoiding the smell of gasoline and the clicking of shutters. Not her. Grizzly 399 chose to raise her cubs in the "front country," often right alongside the roads. She wasn't being friendly; she was being smart. By staying near people, she kept the aggressive male bears (boars) at bay, as they tend to avoid humans. It worked. She lived to the ripe old age of 28, an almost unheard-of feat for a wild grizzly in the Greater Yellowstone Ecosystem.
Then, in October 2024, it ended. A car hit her on a highway in Snake River Canyon. Just like that, the most famous bear in the world was gone. But her story isn't just about a sad ending; it's about how one animal fundamentally changed how we think about conservation, photography, and the precarious line between the wild and the suburban.
The Life and Times of a Matriarch
Grizzly 399 wasn't just a local celebrity; she was a biological anomaly. Most grizzlies in the wild live maybe 15 to 20 years if they’re lucky. She pushed past 25 and, remarkably, gave birth to a litter of four cubs at the age of 24. That’s like a human woman having quadruplets in her 70s. It shouldn't happen.
Nature is brutal. You see it in the way she moved—heavy, purposeful, but always scanning. She raised at least 28 descendants. Some biologists, like Frank van Manen of the Interagency Grizzly Bear Study Team, watched her for decades. They saw her navigate the changing landscape of Wyoming, from thinning whitebark pine seeds to the increasing presence of elk hunters.
Why the world obsessed over her
It’s easy to dismiss "bear jams" as tourist nonsense. You know the scene: fifty Subaru Outbacks pulled over haphazardly, people brandishing lenses the size of bazookas. But 399 offered something rare. She offered a window into the private life of a predator. You could watch her teach a cub how to pin a ground squirrel or see her pause, sniff the wind, and decide whether a group of hikers was a threat or just a nuisance.

- She was tall—standing nearly 7 feet on her hind legs.
- She weighed roughly 400 pounds, though that fluctuated wildly with the seasons.
- Her coat was a distinct, grizzled blonde around the face and shoulders.
She had this uncanny ability to remain "wild" while being "visible." She never became a "problem bear" in the traditional sense. She didn't break into cars. She didn't raid coolers. She taught her cubs to hunt and forage, even if that foraging happened within sight of a visitor center.
The "399 Effect" on Jackson Hole
Honestly, the Queen of the Tetons was an economic engine. People didn't just go to Jackson for the skiing or the overpriced avocado toast. They went for her.
Wildlife photographers like Thomas Mangelsen spent years documenting her every move. His book, Grizzly: The Remarkable Life of a Mountain Icon, basically turned her into a global brand. But with that fame came a massive burden for the National Park Service.
Managing the 399 crowds was a full-time job for the "Brigade"—a group of volunteers and rangers tasked with keeping people at least 100 yards away. It was a losing battle. People are predictably reckless. They’d get too close for a selfie, forgetting that underneath that fuzzy exterior was a half-ton of apex predator capable of outrunning an Olympic sprinter.
The complicated reality of bear management
We like to think of national parks as pristine wilderness, but 399 lived in a hybrid world. She crossed fences. She walked through residential backyards in the town of Jackson. In 2021, she and her four cubs became a logistical nightmare for Wyoming Game and Fish when they started wandering through populated areas, snacking on bee hives and livestock feed.

There was a real fear she’d be euthanized. That’s the rule, usually. "A fed bear is a dead bear." But 399 was "too big to fail." The public outcry if she had been "removed" would have been astronomical. So, the authorities hazarded her instead—using cracker shells and rubber bullets to push her back into the woods. It was a messy, human solution to a wild problem.
What Her Death Reveals About Our Roads
The fact that the Queen of the Tetons died under the tires of a vehicle is a bitter irony. She had survived everything else: drought, rival bears, the threat of being delisted from the Endangered Species Act, and decades of human proximity.
Wildlife vehicle collisions (WVCs) are a silent epidemic in the West. In Wyoming alone, thousands of big game animals are killed on roads every year. The stretch of highway where she died, south of Jackson, is a known corridor for wildlife.
- Fragmentation: Roads slice through migration paths.
- Speed: Even a 5-mph difference can be the gap between a reaction and a collision.
- Infrastructure: We need more wildlife overpasses and underpasses.
Her death sparked an immediate conversation about the Highway 191/189 corridor. If the most famous bear on earth isn't safe, what hope does a random mule deer have? There’s a push now for more permanent mitigation measures, something that’s been in the works for years but always seems to lack the necessary "political will" until a tragedy happens.
The Legend Lives On (Literally)
399 is gone, but her DNA is everywhere. Her daughter, Grizzly 610, is a formidable matriarch in her own right. You can still see the lineage in the Teton valley.

But will there ever be another one like her? Probably not. The conditions that created her fame—a combination of her specific temperament, the rise of social media, and the unique geography of Grand Teton National Park—are hard to replicate. She was a bridge. She bridged the gap between the "scary monster" myths of the 19th century and the modern understanding of grizzlies as complex, social, and highly intelligent animals.
Common misconceptions about the Queen
A lot of people think she was "tame." She wasn't. If you surprised her in the brush, she would have defended those cubs with a ferocity that would haunt your nightmares. She simply had a high threshold for human presence. She tolerated us.
Another myth is that she was "too old" and her death was inevitable. While 28 is old, she was in remarkably good health. She was still hunting. She was still active. She could have easily lived another two or three years, perhaps even seeing her last cub reach independence.
How to Honor the Legacy of Grizzly 399
If you’re heading to the Tetons or any bear country, don't just buy a 399 sticker and call it a day. The best way to respect the Queen of the Tetons is to change how we behave in her kingdom.
Practical Steps for Your Next Trip:
- Slow down at night. 399 was hit in the evening. Visibility drops, and reflexes slow. In wildlife corridors, the speed limit isn't a suggestion; it’s a survival guide for the locals.
- Carry bear spray (and know how to use it). This isn't just for your safety. If you have to use a gun on a bear, the bear dies. If you use spray, everyone likely walks away with a bad story and some stinging eyes.
- Secure your attractants. This means bear-resistant trash cans, locking your car, and not leaving bird feeders out in the spring. 399’s brush with "management" in 2021 was entirely caused by human carelessness with food.
- Give them space. Use a telephoto lens or binoculars. If the bear changes its behavior because of you—stops eating, looks up, moves away—you are too close. Period.
The Queen is dead, but the Tetons are still very much alive. The mountains she climbed are still there, and her descendants are currently tucked into dens, waiting for the spring thaw. She taught us that we can coexist, but only if we’re willing to give a little ground.
Support organizations like the Greater Yellowstone Coalition or Wyoming Wildlife Advocates. They’re the ones doing the unglamorous work of lobbying for wildlife crossings and bear-safe containers. That’s the real work. That’s how you keep the spirit of 399 from being just a memory on a postcard.
