Here I left the trail and climbed UN 10,220. From there, I could finally see my main objective clearly. I dropped to the saddle between the two peaks and angled northwest, climbing along the south edge of the large open scree area on the northeast face of UN 11,048 ("Runs-Down-Fast Mtn.").
A short bit of postholing through the trees brought me to the north ridge, not far from the summit. A little rock hopping brought me to the true summit, just under four hours after my start. I placed a new register (because the existing one from frozen in its jar!) and descended by going all the way down the north ridge to the saddle (to avoid a re-match with the snow in the trees!), where I encountered strong wind from the west. I may not have been "running" very fast, but it was faster than the ascent. I soon found my own tracks in the snow, and the return was uneventful.
