Good climb up the zipper today. Didn't see the need for roping up or placing any pro in the zipper itself, although we had it. We didn't summit via the standard chute on the south side. Instead we climbed the very steep chute you see directly to west when come out of the zipper, it was sketchy good, no pro placed here either :) All of this was during quite the whiteout.
Climbed the Zipper under deep powder conditions. At several times, I could not move forward because every time I tried to move up, snow just crumbled underneath me, creating a waist high wall. We must have spent 3 hours in the couloir, just struggling to make it up. The total climb took us 7 hours RT.
