I am fascinated by that historical event.
Acute radiation poisoning? That’s the theory I find most plausible, if there even IS a theory that’s plausible.
I’m fascinated with the Dyatlov Pass incident too. That, and the mystery of the people missing in national parks and forests as investigated by David Paulides (CanAm Missing 411)
I suspect the Russian governmnent in the Dyatlov Pass incident. Probably some kind of weapons testing and that group of students was in the wrong place at the wrong time.
