Ed Webster informed me that John Turner was 83, when he passed away a few days ago.
Having done most of Turner's routes both in NH, and at Poko, in the Daks, I would say, Turner was establishing the hardest free climbs in this country, in the late 50's. He put in Repentance in 1958, and the pin he or Art Gran stepped on, was well below the off-width crux. There were no bongs to protect the crux at that time.
When I did the route with John Bouchard in 1972, we were fresh from 2 months climbing in Yosemite and elsewhere and I would definitely rate it 5.10. John Turner was an amazing climber, and deserves much respect.
