My buddy and I have dreamed up this wild idea: We want to try to combine a multi-day winter river trip with some riverside backcountry skiing. So, we are trying to find a river somewhere in the west that is at an elevation with significant winter time snowfall, has access points that will be accessible during the winter months, has flows that will be runnable in the winter, and has potentially skiable mountains rising up from the river at some point along the run. Our experience with rivers is exclusively in Oregon (Rogue, Deschutes etc.) which do not get significant winter snowfall and so I am reaching out to all of you and your wealth of knowledge to see if anyone has any ideas for sections of river that might be able to facilitate our crazy idea. Thanks in advance!
