Griffin Post is a big-mountain skier, filmmaker, and expedition leader known for blending high-consequence skiing with storytelling, science, and exploration. Born in Austria and raised in Idaho, he transitioned from ski racing to big mountain skiing, building a career defined by precision and composure in serious terrain. A longtime athlete with Teton Gravity Research, Griffin has appeared in over a decade of iconic ski films while also leading groundbreaking projects like the discovery of Bradford Washburn’s long-lost camera cache in the Yukon. Based in Jackson Hole, Wyoming, his work increasingly focuses on public lands, access, and using skiing as a lens to explore environmental and cultural questions.
Big-mountain skier, filmmaker, and expedition leader Griffin Post and professional snowboarder and adventurer Robin Van Gyn join VIMFF to introduce The Lost Cache, the story of their extraordinary quest to solve an 85-year-old mountain mystery.
In 1937, legendary mountaineer and photographer Bradford Washburn was forced to abandon a cache of camera and climbing equipment deep on the Walsh Glacier in the Yukon after making the first ascent of Mount Lucania. More than eight decades later, the question remained: could it still be out there?
What followed was a multi-year search bringing together skiers, scientists and explorers to track the movement of a glacier and hunt for a piece of mountaineering history. Part expedition, part treasure hunt, and part exploration of obsession and curiosity, The Lost Cache asks why some unanswered questions refuse to let us go.
Following the film, Griffin and Robin will join us for a Q&A about the expedition, the discovery, and the remarkable story behind the film.
