The rescue was definitely a sight to see.  Just to clarify, he basically fell down the slope directly above/behind the top of the fixed lines down to the Peters.  There are no rocks on that slope, just snow and ice, upon which he was unable to self arrest.  a cartwheeling situation landed him into a crack where he opened up his jacket, pulled out a sat phone (that was somehow not in his pack, which was ripped off and yard saled), and called 911.  it also happens that he landed next to a tent that had blown down from 17k a couple days before; he wrapped it around himself until the NPS got there.  Super lucky...
