Although I never even saw an actual AA print until I was exhibiting my own color prints almost in his back yard there in Carmel, I did subsequently have the opportunity to see quite a number of his prints up close. Most people see only a few classic images over and over again in published fashion, and mostly the more dramatically contrasty or theatrical ones, for lack of a better term. But he had a tremendous capacity for sensitive poetic expression that is overlooked by those who, as you imply, have come to think of this as just an easily cloned genre or zone system cult or whatever. Even in his own heyday, quite a few commercially-minded photographers despised him as "that rocks and trees guy", even though he was a highly competent and successful commercial photographer himself.
Eliot Porter is another person who people now tend to devalue just because so much of his subject matter has been nominally copied, though seldom equalled for nuance. Now it's all about some knot-head "its the subject which counts" mentality, whatever that means. I deliberately try to keep my own prints nuanced and layered rather than in your face like a pie or advertising photo. The objective is to keep rewarding the viewer over and over again, year after year. Any "subject" too accessible is likely to be shallow. But that's the whole point of the advertising "gotcha" mentality - grab you attention instantly; after that, who cares.
I've never personally been to Precipice Lake because it's actually on a popular major trail. I've always tended to be an off-trail type, and one of the last holy grail sanctuaries I've gotten into in recent years, while I still can, was several off-trail divides behind that area, without any evidence of human presence at all, though climbers do sometimes get in there. My 70's are getting to be quite a challenge in terms of both including LF gear in my pack and still hoping to do a certain amount of off-trail travel. More secluded trails in combination with somewhat less rugged off-trail terrain might be my only way forward. That's what I found in the northern Wind River range for a couple weeks last year; and some of those trails were pretty darn rough and unmaintained themselves. More moose than people.
