Jarbidge, West Fork

There is definitely a run on the WF Jarbidge between the town of Jarbidge

and the EF Jarbidge. It's really no more than class 3-4 though. Not certain

of what lies above which is what you seem to be asking about. There is also

some decent potential on the EF Jarbidge (have done a backpack scouting trip

in there) but access would be very difficult at best due to snow i.e. once

hiking in without snowshoes becomes feasible, the water is gone
