Sender Films is currently working on a feature documentary about the counterculture climbing scene in Yosemite over the last 50 years. Provisionally titled “Valley Uprising,” the film brings all the legends to life: from Royal Robbins’ epic battle with Warren Harding to the fabled drug plane crash of 1977 and the escalating tensions between climbers and national park rangers. This year’s REEL ROCK Film Tour will include a teaser clip from the film that focuses on the sex-drugs-n-rock era of Jim Bridwell and the Stonemasters
