Some people meet the Klamath Mountains only once or twice in their lives. Others feel the call so strongly that it becomes a kind of compass. Dr. Brad Marston — physicist, professor at Brown University, and our 2025 Volunteer of the Year — is one of those people whose life keeps bending back toward this rugged, rain-washed country.
In this episode of Bigfoot Trail Tales, we sit down with Brad to explore the winding path that brought him from the world of theoretical physics to the deep canyons, marble caverns, and trail corridors of the Klamath Range. Brad talks about his early spark: a geology book that nudged him west in 1985, turning curiosity into a lifelong connection. From that first backpack in the Salmon Mountains to long days of trail work in the Yolla Bollys, he’s carried a scientist’s eye and a trail worker’s heart.
Over the years, Brad has blended both worlds with clarity and wonder. He speaks about the therapy of swinging tools, the joy of wandering off-trail to discover rare plants on Marble Mountain, and the strange beauty of places like the Yellow Bullies where fire, time, and limestone shape whole stories in stone. He’s even woven the mountains into his academic life, sharing how limestone dissolution in the Marbles pulls carbon from the atmosphere — a quiet process of healing hidden inside the range.
Brad also reminds us why long-distance trails matter. They knit ecosystems together. They help wildlife move. They help people understand change, especially in a time when fire is rewriting the map. As he points out, more than half of the Bigfoot Trail has burned since 2015, a living lesson in resilience and transformation.
And behind all of it is a simple truth: trail work is a form of care. It’s physical, grounding, mindful, and joyful — a way of tending the land that has given him so much.
As Brad looks toward retirement, he and his wife hope to move to Northwest California to be closer to the mountains that have shaped him. We could not imagine a more fitting homecoming.
Join us for this conversation — a blend of science, story, stewardship, and the steady pull of a landscape powerful enough to reroute a life’s trajectory.
