Rappelling from the troll's head

There's a well-placed bolt driven into the troll's skull. Well, there was perhaps a better spot. Where this bolt is located and where we rappelled meant a little bit of an awkward step off at the top. If the bolt had been placed about three feet closer to the camera, there would have been a nice ledge to step down onto to begin the rappel, not the same ledge with a slight pendulum. Who set this bolt, anyway? July 2011.
