First, condolences to all who knew her, sounds like she knew what she was doing, and what she was getting into.
In reply to:
The coroner's office said Gray died of blunt force trauma to the head from colliding with the rock face.
Any word about a helmet or not? From what Vegastradguy said, it sounds like it might not have made a difference, but still makes me wonder. I could see a 50 footer causing severe blunt force trauma even if she was wearing a helmet.
