Another option is to fly to Denver, CO, which is less than 7 hours drive from Ten Sleep. Cheapest flights might be with Iceland Air, which flies non-stop from Iceland to Denver.
From Denver, you can also check out all the climbing (several lifetimes' worth) around Boulder and the Front Range.
Also, Colorado is the microbrew capital of the US.
Tons of detailed route information and an on-line guidebook at mountainproject dot com.
Have fun!
