Mt Whitney Zone Forums General Discussion Mount Russell to trail camp

If I am planning on doing mount Russell next summer and then the plan would be to meet my group at trail camp which is where we would spend the night, to then go do Whitney the next day hopefully along with muir. Is there any way to get from upper boy scout lake to trail camp without doing climbing mount whitney or going all the way back down? I looked at pinnacle ridge but the northern side looks pretty steep. Also if those are really the only two options which would you recommend.
