Yosemite, 1970’s – it was the heart of the climbing revolution. You’ve heard a lot of voices and names in the Dope Lake series – John Long, Jim Bridwell, John Bachar, Dale Bard, Vern Clevenger, John Yablonski. Big names with big personalities that helped write the history of Yosemite Valley across all the disciplines – big wall, free climbing and bouldering. When the decade started, the hardest route in Yosemite checked in at 5.10. By the end of the decade, that standard would climb to 5.13. Lis
