Wow, what a trip you had....man..
So, both peaks in one day from the trailhead?? ..or once at the Pass?
Looking this over, I think I might have to wait until I have an extra day for Tyndall later in the summer/fall. For next week timing, 27+ miles, with 8000ft gain with the expected snow might be a bit much to do car-car in a day without much time to acclimatize.
