13. About a mile or so from completion of the hike, I began to notice helicopter sounds. I was high enough that I could see the helicopter flying into Tyndall Gorge. He was carrying something at the end of a long cable. My first thought was Oh No, a rescue. It soon became apparent that he was making not one, but several passes up into Tyndall Gorge. Then I thought; fire? I don't see any smoke.
