He isn’t a myth. If you spend enough time around the Bow Valley in Alberta, you’ll hear the name whispered like a local legend. They call him The Boss. Formally known to Parks Canada researchers as Bear 122, this nearly 700-pound behemoth has become the undisputed grizzly bear king of Banff National Park. He’s huge. Honestly, seeing him in person—from a safe distance, obviously—is a reminder that nature doesn't care about our schedules or our fences.
The Boss isn't just a big bear. He is a survivor of things that would have killed a lesser animal years ago. He’s been hit by a train. He survived. He reportedly ate a black bear. He’s fathered a significant portion of the cubs in the park. When people search for the grizzly bear king, they aren't looking for a fairytale; they're looking for the reality of 122. He represents the raw, unfiltered struggle of the Canadian Rockies.
What Makes Bear 122 the True Grizzly Bear King?
Size is the first thing people notice. Most interior grizzly bears in the Rockies don't get this big. While coastal grizzlies gorge on salmon and can tip the scales at 1,000 pounds, their mountain cousins usually have a harder time finding high-calorie meals. Not 122. He has mastered the art of the "buffet." He frequents the Canadian Pacific Railway tracks, scavenging grain that leaks from rail cars and, more importantly, finding the carcasses of elk or deer that weren't fast enough to get out of the way of a locomotive.
It’s a dangerous game. The tracks are a literal death trap for many animals. In fact, 122 himself was struck by a train and somehow walked it off. Most bears don't get a second chance with a freight train. He did. That’s why he’s the grizzly bear king. It’s about more than just brute strength; it’s about a specific kind of rugged intelligence and a high tolerance for risk.
Biologists like Seth Cherry have tracked 122 for years. They’ve seen him navigate through townsites and busy highway corridors with a level of "urban awareness" that is frankly terrifying. He knows where the people are, and he knows how to avoid them while still getting what he wants. He isn't aggressive toward humans by nature—he’s just busy. He’s got territory to defend, which spans over 2,500 square kilometers. That is a massive amount of real estate for one bear to hold down.

The Black Bear Incident
You might have heard the story about him eating another bear. It sounds like sensationalist clickbait, but it’s actually documented. Back in 2013, wildlife officials found the remains of a black bear that 122 had hunted and consumed. This isn't common, but it isn't unheard of for a dominant male grizzly. It sent a clear message to every other predator in the valley: this is his house.
When we talk about the grizzly bear king, we’re talking about an apex predator that sits so far at the top of the food chain that his only real threats are human-made. He’s the patriarch. Genetic testing on cubs in the park has shown that Bear 122 is the father of multiple litters. His DNA is literally the future of the Banff grizzly population. If you see a cub in the Sawback Range, there’s a statistically significant chance it carries the genes of The Boss.
Why the Grizzly Bear King Matters for Conservation
Banff is a crowded place. Millions of tourists visit every year, and most of them want a selfie with a bear. This creates a massive problem for Park Rangers. The Boss is actually a success story in a weird way. He has lived to an old age (he’s well into his 20s now) despite living in one of the most heavily trafficked national parks in the world.
The survival of the grizzly bear king is a litmus test for our ability to coexist with nature. If a bear as large and active as 122 can navigate the maze of highways, trains, and hiking trails, there’s hope for the species. But it’s a fragile peace. One mistake by a tourist leaving out a cooler or one bad encounter on a trail could end his reign.

- Habitat Fragmentation: The Trans-Canada Highway and the railway cut right through the heart of his territory.
- Climate Change: Shifting berry seasons mean bears have to travel further for food, increasing the chance of human conflict.
- Human Pressure: More people on trails means more chances for a surprise encounter.
The Boss uses the wildlife overpasses and underpasses. He’s been caught on camera using the infrastructure we built specifically to keep him off the road. He’s adapted. He’s a "culture-bearing" animal, meaning he’s learned how to survive in a human-modified landscape and might even be passing those behaviors down to his offspring.
The Reality of Tracking the King
There’s a lot of misinformation out there about how these bears are managed. Some people think they’re "tame." They aren't. Parks Canada uses a mix of GPS collars and remote cameras to keep tabs on the grizzly bear king. It’s not about "spying" on him; it’s about public safety. If 122 is hanging out too close to a popular campsite, the rangers might close that area.
You’ve probably seen the "Bear Closed" signs if you've hiked in the Rockies. Those aren't suggestions. They are usually there because a high-ranking male like 122 is in the area, likely guarding a carcass. A bear on a "kill" is the most dangerous version of that animal. They will defend that food source with everything they have.
Actually, if you’re ever in the park and you see a massive, dark-furred bear with a distinctive hump and a bit of a swagger, it might be him. But honestly, you should hope it’s not. Seeing a grizzly of that size in the wild is a life-changing experience, but it’s one that requires an immediate, calm retreat.

Common Misconceptions About Bear 122
People often think he’s a "problem bear." He’s actually the opposite. A problem bear is one that seeks out human food, hangs around parking lots for handouts, or loses its fear of people. The Boss is "habituated" but not "food-conditioned." He knows humans are there, but he doesn't see us as a source of snacks. He just sees us as a minor annoyance to be bypassed on his way to his next real meal.
Another myth is that he’s the only one. While he’s the grizzly bear king of the Bow Valley, there are other big males, like Bear 136 (Split Lip), who is known for eating other grizzly cubs. It’s a brutal, violent world out there. The Boss has to defend his crown every single season from younger, hungrier males looking to take over his prime real estate.
How to Exist in the Realm of the Grizzly Bear King
If you're heading to the Rockies, you are entering his territory. Period. You don't need to be terrified, but you do need to be smart. Being "bear aware" isn't just a catchy phrase for a brochure; it’s the price of admission for the mountains.
- Carry Bear Spray—And Know How to Use It. Don't keep it in your backpack. Keep it on your belt or chest. If a grizzly is charging you at 35 miles per hour, you won't have time to fumble with a zipper.
- Make Noise. The Boss doesn't want to meet you. If he hears you coming, he’ll likely move off. It’s the surprise encounters that turn deadly.
- Look for Sign. Fresh scat (which looks like a pile of digested berries or hair), overturned logs, or claw marks on trees are all signs that the grizzly bear king or one of his subordinates is nearby.
- Respect Closures. These are often based on real-time GPS data. If a trail is closed, it’s because a bear is literally right there.
The Boss is getting older. Grizzlies in the wild rarely live past 30. We are currently witnessing the final years of a legendary reign. When he eventually passes, it will be the end of an era for Banff. He has been the face of wildlife resilience for over a decade.
Basically, the story of the grizzly bear king is a story about the wild heart of the mountains refusing to be tamed by the 21st century. He’s a reminder that even in a world of high-speed rail and 5G, a 700-pound beast still calls the shots in the high country.
Next Steps for Your Mountain Adventure
- Check the Parks Canada "Bulletins" page before you go. This gives you the most up-to-date info on where Bear 122 and other grizzlies are currently active.
- Invest in a high-quality inert bear spray canister. Practice the drawing motion until it's muscle memory. You don't want your first time "firing" to be during a real encounter.
- Download an offline map app like AllTrails or Gaia GPS, but pay attention to the user comments. Hikers often report recent bear sightings there faster than official channels can update.
- Keep your distance. If you see a bear from your car, stay in the car. If you see one on the trail, give it at least 100 meters. The grizzly bear king earned his title—don't make him defend it against you.
