In grizzly country, there are trees that tell stories. They’re not marked with signs, but every bear that passes knows exactly what they mean. These rubbing trees are the bulletin boards of the mountains, where grizzly bears leave messages, scents, information, and sometimes just an itch they need to scratch. Age, size, mood, mating status, dominance, it’s all communicated here without a sound. For years, I’ve walked past these trees knowing bears were using them. But in this episode of Endless Venture, I finally set up cameras and witnessed what actually happens when a big grizzly (or little) finds one. It’s not just scratching on bark. It’s communication. It’s territory. It’s identity. It’s a glimpse into how these animals connect with each other in a world where they rarely meet face to face. Watch this episode now on Endless Venture YouTube.

In this episode of Endless Venture, Riley and I head deep into one of the most densely populated grizzly bear areas in the lower 48—a wild corner of the backcountry where spring beauty corms, tender grasses, roots, and newborn elk calves fuel a thriving population of big, charismatic bruins. Decades ago, I stumbled across an old cattle trough out here — left behind by cowboys long before livestock ever stopped grazing these mountains. Today, the wild has reclaimed it completely. Grizzly bears now use this forgotten tub as their personal high-country cold plunge, a place they slip into year-round to cool off, soak, and sometimes interact with one another in ways few people ever get to see. Surrounding the trough is a network of rub trees, where bears leave their scent, communicate, and map out the social structure of the landscape. With a collection of camera traps placed strategically around this oasis, we capture intimate, candid moments of grizzlies living their lives—bathing, rubbing, playing, and sharing this incredible wilderness. At the end of october, Riley takes over for one final camera-trap check of the season—and that’s when it finally happens. After nearly a year of trying, we capture the shot we’ve been dreaming about since the day we set our first cameras. This one is special. Raw, wild, and deeply personal.

Tools of the Trade. Most of the male ungulates, the hoofed animals that roam North America, carry either antlers or horns. And in this case, we’re looking at one of the true heavyweights of the horned world. This bighorn sheep ram wears his life story on his head. Unlike antlers, which are shed and regrown each year, horns are permanent. They’re made of keratin, like your fingernails, wrapped around bony cores and fused to a reinforced skull built for impact. They grow slowly, year after year, thickening, curling, and recording everything this ram has been through. Look closely and you’ll notice growth rings marking the years. Chips, cracks and worn edges left behind from brutal head-to-head clashes. Deep dents from bone-rattling impacts. And the sweeping curl that reveals age, dominance, and survival. These aren’t just horns, they’re a biography. A record of time, weather, battles, victories, and close calls. Every ridge has a story. Every scar has a cause. The longer you look, the more you can read. So cool.

In this episode of Endless Venture, I team up with my good friend, Coyote Peterson, for an adventure deep into one of Yellowstone’s best-kept secrets—a hidden graveyard in the wild. This mysterious valley is where the old, the weak, and the winter-fallen animals come to rest… and where life begins again for the scavengers that depend on them. As we explore this hauntingly beautiful place, we uncover the massive skulls of bull bison and elk, scattered antlers, and the raw story of life and death written across the landscape. It’s a powerful reminder that even in death, every creature plays a vital role in the circle of life. Join us as we journey into Yellowstone’s secret graveyard—where the wild tells its truest story.

You’re a coyote, you follow your nose to the scent of a rotting elk carcass hoping for an easy meal, but someone’s already claimed it… a grizzly bear. What do you do?

This might be one of the craziest ideas I’ve ever taken had. In the middle of November, during the first big winter storm of the year, Riley and I hiked deep into the Montana wilderness to spend the night inside a real bear den. On the way up, we found fresh bear tracks heading straight toward the cave — and that’s when things got intense. We had to move fast, racing against the storm and hoping the bears didn't beat us to the den. Spending a night where a grizzly sleeps isn’t something you take lightly, but it’s moments like these that remind me why I do what I do — to get closer to the wild and tell stories few people ever get to witness. This episode is raw, real, and unlike anything you've ever seen before.
