Thanks for the intel. I definitely would like to explore that area more.
My understanding is that Hell For Sure and North Fork are impassible from below although supposedly one can ascend the North Fork if one can detour to the west around the falls at the lower end of the North Fork. From the photos I've seen, it would be no easy task.
The route up the ridge from Middle Fork to Bighorn Mountain is supposedly doable, but that would be a rough go.
