Mount Russell, The Mithral Dihedral. This excellent route ascends the large left-facing dihedral just right of the Direct Southwest Buttress; the routes probably share the first one or two pitches. Alan Roberts and I climbed it in July via five pitches of sustained, spectacular jamming.
Only one pitch was under F8, and superb rock accepted chocks readily. NCCS III, F9.
