...for the description. I didn't know about the "ramp" at the op of the classic chute. I soloed the peak in 1993, first attempting the classic chute all the way to the top. It was steep as hell with a vertical pitch at the top (cornice remnant). I tried following the ridge from there, but I was over my head. I down-climbed all the way to the glacier and then ascended the right-hand chute (MUCH easier). The photos are really helpful.
It appears to me that the first ten vertical feet of the classic chute is not class 3 but class 4.
