New Dyatlov Pass theory......

Sounds feasible...

from the article OP posted above:

"Researcher Vadim Skibinsky believes the fireballs were the exhaust gases of a launched rocket. Not only was Russia carrying out missile launch tests throughout February 1959, but reports also say the snow melted around the camp, but not in other places nearby, leading to the manmade conclusion instead of a weather event.

The research team believes the launching—and a subsequent failure—of an R-12 liquid single-stage medium-range ballistic missile resulted in a nitric acid fog reaching the tent. Since testing happened within range of the mountains, and because nitric acid is a colorless, highly corrosive mineral acid used as an oxidizer in liquid-fueled rockets that can cause confusion and pain, the continued search for the truth about the Dyatlov Pass Incident may have moved well past exposure and avalanche directly into a fog.

But was it a fog of nitric acid?

Was remote viewed by Farsight, was a military exercise they stumbled upon.

They had to go.

interesting case..last theory I heard was sheet avalanche

But, still, one woman's tongue was missing. Would the acid fog cause that?

Yes!
Some had burns resembling radiation burns

It's not feasible, it plausible.
And no not plausible, complete bullshit.
