Back to the Trail Camp incident in the first post above:

On FB, the same report exists, and there are several dozen comments calling the guy names, proposing he pay, calling him a moron, etc.

...then this: "Ran into this guy at trail camp yesterday. He was very very delirious and my buddy and I couldn't make out what he was talking about. He kept asking if a car could pick him up at trail camp. Not entirely sure what was going on."

This sounds like a possible HACE (High Altitude Cerebral Edema) symptoms. People with that can die out there -- or walk out on their own. Dicey situation at least.
