Some pass on the way.
I ended up sleeping at a place called Ice Lake. About 5 miles of backpacking from 9,500 feet to a sleeping elevation of a little over 12,000 feet.
Hiking up, a lower lake, and the view from my tent.
It was breathtaking. Unfortunately, it also turns out that when you live at sea level for 3 months and then attempt to sleep at 12,000 feet that you get headaches and nausea and stuff associated with altitude sickness. Its not cool. Don't do it.
