Ascent to North Dome had steep and deep snowdrifts and icy grade 1 scrambles. Many of the more direct passes up were too steep and icy and required technical climbing, walked around a bit and picked a non technical path up. No herd path was visible until after North Dome summit. Descent to col and ascent to Sherill was less complicated, but also steep with deep snowdrifts and scrambles. No views on either peak.
