Open Book is a technical rock climbing route at Tahquitz Peak, CA.[1] Since the Yosemite Decimal System was developed at Tahquitz it is no coincidence that the first climb to be rated 5.9, Open Book, is also located at Tahquitz. In 1952, when Royal Robbins climbed it free, it was one of the most difficult free ascents in the country.
