Ok, perhaps I am missing something, although I did watch the first part twice. If that is real video footage (assuming that Michelle was shooting and not belaying Stephen, who has snowboarded the north side of Everest), it sure looked to me like her leader did not put in a single piece of pro on that traverse, and some of that ice looked like it could have taken a few screws. So, I am wondering if he should have tried harder to protect his second, which may have shortened the length of her pendulum fall? In any case, the Valhalla traverse sure looks a lot harder now than when we traversed it to make an early ascent of the Enclosure couloir in 1972, which at the time was the classic warm up climb for the Black Ice couloir in the Tetons.
