Do you have any evidence at all that this was someone from the lower 48?

Depends on how much you trust Wikipedia

I think the parent commenter was referring to this incident, not the kid from Into the Wild. Based on the demographics of the two villages he was traversing, it's very likely that this man is Alaska native.

Thanks for clearing that up. I must have misread the article based on my prior knowledge of Into The Wild and some of the comments previously made.

That guy was definitely out of his depth.
