Superb route concept, Dave! You passed through just about the finest the southern Sierra has to offer. It doesn't get much better, IME. Thanks for sharing.
" Climb Triple Divide Pass, and traverse to ridge, climbing atop it. Not able to initially find the way off the end that Bill Finch discusses, and find ourselves dropping to be stymied on narrow granite cliffs. Turn around and to back up, only to find relatively easy way down."
Are you referring here to the ridge that Secor advises crossing at 12,000', just south of the Colby Pass Trail and overlooking it? If so, I can second your confusion. I had trouble finding the route down, too. It is much easier to figure out going up, enroute to Triple Divide Pass.
