Join Heyday author Dillon Osleger for a book signing at the Telluride Mountainfilm Festival. Held every Memorial Day weekend, the Mountainfilm festival brings together a community of filmmakers and change makers, showcasing documentary films that celebrate adventure, activism, social justice, environment and indomitable spirit.

Dillon Osleger is a scientist, writer, and environmental advocate whose work is anchored in society’s relationship with wild and rapidly changing environments. With an academic background in geology, ecology, and climate science, he has spent over a decade working on trail restoration, land management, and public lands policy across the American West. His writing has appeared in Outside, the Los Angeles Times, Patagonia’s The Cleanest Line, and Earth and Planetary Science Letters, focusing on the confluence of land use, climate, environmental justice, and historical memory. Whether in Washington, D.C., or the backcountry of the Sierra, Osleger brings a grounded perspective to how people move through and care for place. Trail Work is his first book and he lives in Truckee, Lake Tahoe.
