What climbs at Tahquitz were the original definitions of YDS class 5 grades?

+0
−0

From what I understand of the history, Yosemite Decimal System (YDS) grades came about when class 5 in the preexisting system was subdivided into 5.0 through 5.9. This was done by Chuck Wilts, Royal Robbins, and Don Wilson, who were members of the Rock Climbing Section of the Angeles Chapter of the Sierra Club, as part of Wilts's 1956 guidebook to the Tahquitz Rock area. A particular climb served as the original definition of each decimal point. Wikipedia states that The Trough was the original definition of 5.0, while Open Book defined 5.9. What was the list of ten climbs that defined these grades, and what grades are they considered to be?

Below is the list that I found by googling on "chuck wilts" 1956 tahquitz yds. After the name of each route is the consensus rating on mountainproject.com. Each climb is hyperlinked to a description on mountainproject.

5.0 - The trough, FA 1936 (.4)

5.1 - Fingertip traverse, FA 1936 (.4)

5.2 - Frightful variation of the trough, FA 1944 (.2)

5.3 - East lark, FA 1950 (.5)

5.4 - Angel's fright, FA 1936 (.6)

5.5 - Ski Tracks (left .6, right .9), FA 1947, 1957

5.6 - Sahara terror (.7), FA 1942

5.7 - Fingertrip (.7), FA 1946

5.8 - Mechanic's route (.8 R), FA 1937

5.9 - Open book (.9), FFA 1952 (aided previously)
