Over 40 grizzly bears… in a single day. I’ve spent my life in bear country, from Alaska to Yellowstone, and I had never seen anything like this. My previous record for grizzlies seen in one day in the Yellowstone ecosystem was 24. This trip shattered it. High in the alpine backcountry of the Greater Yellowstone, bears covered the mountainsides in every direction, flipping boulders for army cutworm moths and tolerating each other in ways you almost never see. But walking through a landscape with that many grizzlies comes with consequences. Every move matters. Wind. Terrain. Noise. One wrong decision and things can escalate fast. One of the wildest bear experiences of my life. New Endless Venture episode is live now on our channel!

There are days in the field you know you’ll never forget—and this was one of them. In this episode of Endless Venture, Riley and I head deep into the backcountry, climbing to over 13,000 feet in elevation to witness one of the greatest wildlife spectacles in North America… and one that very few people have ever seen. Years ago, my personal record on this mountain was 24 grizzly bears in a single day. I thought that was unbeatable. In this episode, we shatter that record. Every late summer, millions of army cutworm moths migrate from the plains to these alpine peaks, feeding on wildflower nectar before hiding deep in the rocky slopes above treeline during the heat of the day. Grizzly bears from all across the Greater Yellowstone Ecosystem know exactly where to find them—and they travel incredible distances to feast on these tiny insects, packing on critical fat before winter. What unfolds is the wildest day we have ever experienced in the United States… and maybe one of the craziest days of our lives. Dozens of grizzlies. Multiple close encounters. Endless adventure. This is one you do not want to miss.

In the Yellowstone ecosystem, the rivers are often what deliver springtime first. As the ice begins to break apart and the water rises with snowmelt, the currents start carrying more than just runoff downstream. Every spring, bison, elk, deer, and other animals that fell through the ice during winter, or were caught in dangerous high-water crossings, end up washing downriver and collecting along banks, eddies, and shallow gravel bars. It may seem harsh, but these places become critical food sources for the ecosystem. Wolves patrol the river corridors. Grizzly bears emerging from their dens key in on these carcasses. Ravens, eagles, coyotes, foxes, and countless smaller scavengers all converge on the not-so-fortunate. In a landscape like Yellowstone, very little goes to waste. It’s one of those reminders that spring in the wild isn’t just about new life. It’s also about the long winter finally giving back what it took.

When you spend enough time moving through the mountains of Montana, you never know what you might find. They don’t call it the Treasure State for nothing. This time of year, a lot of folks are out looking for shed antlers, or what people around here call horn hunting. Every spring, elk, mule deer, white-tailed deer, and moose drop their antlers and begin growing a brand new set all over again. Out on public lands, not in national parks, people hike ridges, timber, burns, and creek bottoms searching for these little natural treasures hidden across the landscape. I used to be obsessed with horn hunting when I was younger. These days, it doesn’t excite me quite like it used to… except for what I found today. A matched pair of Shiras moose paddles, the biggest set I’ve ever found in my life. Most of the time, unless they’re exceptional, I leave antlers right where I found them. But these ones? These are coming home with me.

Well, it’s that time of year again. Bears are out of the dens, and unfortunately we were reminded of that after reports that two brothers were mauled by a grizzly bear in Yellowstone just a couple days ago. If you spend time hiking, camping, fishing, hunting, running trails, or exploring the outdoors in the West, you need to assume you could encounter a bear at any time. The single biggest thing you can do to protect yourself in bear country is arm yourself with knowledge. Learn how to react during an encounter. Learn proper bear behavior. Learn how to keep a clean camp. Learn how to recognize warning signs before a situation escalates. Your actions matter. Check out my YouTube channel, Endless Venture, if you want to learn more about living and traveling safely in bear country. But most importantly, get out and read, study, and prepare yourself before you step foot into grizzly country. Because out there, knowledge really can save your life.

Out here, possession is everything. This grizzly has the position on a bison carcass in the Yellowstone River, and because of that, the wolves give ground. But sometimes the roles are reversed. Sometimes the wolves have the numbers, the confidence, the leverage, and even a giant grizzly steps aside. It changes constantly. A game of inches. A shifting balance of pressure, body language, bluff, and timing. Watch closely and you’ll see the wolves already have blood on their faces. They’ve been feeding too. Maybe moments before this they were shoulder to shoulder with the bear, all of them testing invisible boundaries and tolerance levels. How close is too close? How much pressure can you apply before somebody reacts? One wolf pushes just a little too far and the bear makes its point instantly. But what’s fascinating is that almost none of these interactions are about actually hurting one another. An injury for a wolf or a bear can mean starvation, suffering, or death. So instead, they posture. Bluff. Probe. Push. Retreat. Like poker players reading tells. Like chess pieces maneuvering for advantage. Like a runner stealing a base a few inches at a time. And as more wolves arrive, the entire equation can change again. This is happening constantly across Yellowstone and wild places everywhere, whether we see it or not. Ravens waiting for scraps. Wolves testing boundaries. Bears defending position. Every carcass becomes a living negotiation. And no two games are ever the same.
