Agree with Fox
We had 3 weeks to do grand canyon lake Powel arches Bryce zion LV and Yosemite. We did the tetons Yellowstone and glacier in our last trip of 3 weeks. Glacier is 1350 from LV that would be 4 days just getting there and back. Try a less ambitious route we did this in the last 3 weeks.
Do glacier on another trip it is worth doing at the same time as Yellowstone.
