You asked earlier about the ridge just north of the Sentinel Creek Trail. I can't seem to find any photos, but from what I vaguely remember, it shouldn't hold any unreasonable difficulties on the south side. North side should be straightforward (probably easy).

The photos I have from the top of Imp suggest no impassable sections, but the was a fair amount of snow (mid-June this year). PM me if you want to look at them.
