In the 1954 first edition of the Sierra Club's first climbing guidebook to the High Sierra, only one chapter was devoted to Yosemite Valley. By 1964 195 new routes had been put in, including the Nose and the Salathe Wall, which today still attract climbers from all over the world.
This edition of this guidebook is probably the most important California rock climbing guidebook, as it spurred the next generation of climbers to more big walls and hard free climbs, and thereby raised the standards of climbing throughout the world.
