Glad the OP had a chance to go explore and discover the area for himself. Mt. Morrison looks crazy good from afar but the rock is junk unfortunately. You have years of fun exploring ahead of you. Enjoy. As for:

Your response if misleading since some of the crags you mention top out on top on longer cliff bands with no easy descent, if they top out at all, making fixed anchors necessary. Also, what you don't appear to realize is that the norm you're referring to, at least at some of the crags, is a newer development than you might suppose. One of the most active developers in the area, Marty Lewis, pretty much bolts everything, even cracks. He hangs chains on some routes so folks don't need draws, etc. However, given the amount of rock and routes he's opened, most folks are clearly cool with that and it's probably safe to say that his methods have been adopted as an acceptable practice by most (though not all). As such, it's hard to characterize some of these places as trad. With the exception of a few older routes like Pratt's Crack, Pine Creek is a newer crag developed with more of a sport ethic than a trad one. Had you visited the Eastside 20 yrs. ago, you would not have seen anchors lining every route, nor the type of convenience bolting at place like Patricia Bowl. Compare the number of bolts in nearby places like Tuolumne, the Valley and Tahoe for a more representative picture of trad bolting standards.
As for the notion that 'we care about our impact on fauna, so we bolt'. Puuleeeze. It's for convenience. Let's not misrepresent our true intentions because of an incidental benefit.
