Open Book is a technical rock climbing route at Tahquitz, CA[1]. Since the Yosemite Decimal System was developed at Tahquitz it's 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.
