Welcome to HST!
Have not done this section as a whole trip, but your planning to do a part of what is
called the Redline Ski Traverse.
After Pika Pass which is quite steep (class 2) continue on to Franklin Lake where you'll
have to make decision on whether to go over Franklin Col, which is crazy steep, Pants
Pass steep, and then go on to the Bard Pass-Carter Col combo to get to Cecil Lake
from where you climb up to Gemini Pass (class 2), and summit from there.
Your alternate route would be to go over Pretty Pass instead of Franklin Pass, and
believe me, there is nothing pretty about this pass, though not as steep as Franklin, the
talus & boulders are very tedious.
From the east side of the pass you would go to Constance Lake where there is couloir
which leads up toward the summit, but this is not an option because it is a
very steep, think 45 degrees, mountaineer route / skiing route with snow and ice. http://adventuresportsjournal.com/tag/r ... e-mountain
But instead from Lake Wit-so-nah-pah go south over the talus and snowfields to the first
saddle which is Gemini Pass a class 2 pass west of Red Slate Mountain, and summit from there. http://www-rohan.sdsu.edu/~rlilly/High_ ... ass_N.html
The Pretty Pass variation would be my pick of the two routes because you not only have
to climb only 3 class 2 passes, get to visit the pretty upper part of the Convict
Creek drainage, and you do not have to climb nasty Franklin Col!
