In the 1950s, a group of rock climbers began congregating in Yosemite National Park  to attempt some of the steepest climbs there.  They saw themselves as renegades, rebelling against the conservatism of the post-World War II era.  

A new documentary by Boulder filmmakers captures their story, and the story of those climbers who came after them. “Valley Uprising: Yosemite’s Rock Climbing Revolution” has its first screening this week in Boulder. Filmmaker Nick Rosen of Sender Films speaks with Ryan Warner about the early climbing culture in the West.
