Replying to 1-2 night backcountry trips around CO/UT?

A couple of friends and I are looking for a cool 1 or 2 night trip somewhere in CO, maybe UT. Mostly just to gain some experience and use it as a way to practice backcountry/avy skills. dont even need to ski really, just get out in some low consequence stuff. we've got backcountry nordic skis and touring skis.
We wanted to do conundrum hot springs just because it'd be an awesome trip, but from what ive read the area is super avalanche prone. any other suggestions for something on the safe side yet cool. What we dont want is some easy 5 mile trip in and out, we want some challenge.
any advice?
