Thanks for sharing that article, as well as your siblings' thoughts on the case. They definitely support the reality that these areas are dangerous even for experienced hikers! I feel like she dropped her camera lens and while looking for it, she fell through a hidden hole or crevice in the ground, or behind some thick bushes. She was knocked out or even killed on impact, and the area obscured her body. That's why she didn't call for help or respond to anyone looking for her, and why no one saw her. I think she's relatively close by to where she was last seen, but sadly was just overlooked.
