Can you spot the helicopter?

I noted this helicopter while climbing on Clyde Minaret, a few miles away. It gave me that slightly sick, anxious feeling one gets when realizing that something bad has happened (I presume it was on a rescue or recovery mission). On another note, it really gives one a notion of how massive mountains (Banner Peak, in this case) really are! If you know the circumstances leading to the dispatch of the helicopter, I'm curious to know what happened. 15 August, '9
