Sounds like you gave it a good try. When Jim, Bob and I downclimbed it, we were a day late coming off the N.E. Rib, tired, hungry and thirsty. It sucked, and was as mentally tedious as it was physically exhausting to face in for so long. The snow was very hard, but not yet reduced to alpine ice. Our aluminum crampons and light-duty axes were sufficient, but did not inspire tremendous confidence, especially at the top. I'm sure it's much more entertaining to climb up than down.
Has no one else done this one?
