The Box Canyon of the Clarks Fork of the Yellowstone River is the third deepest canyon in the United States and shapes some of the most dangerous and least accessible whitewater in all of North America. The sheer granite walls surrounding this stretch of river inspires awe—and development. It's the perfect place for a dam. Starring Yvon Chouinard along with other conservationists, Our Local Epic is a documentary feature from Aaron Pruzan and Will Taggart about the river, its history, and its future.
