Hello pjhire89 and welcome to the forum.
What a wonderful sounding trip, especially the part about backpacking to secluded areas.
I'm sure if someone has experience of the Rockies in the US they will be along to give you a few pointers, but you may obtain more extensive information by posting your question on the US sister site (this one is UK based):
The North American Fly Fishing Forum. Fly fishing news and views across the USA and Canada

Good luck!
