Dyatlov Pass Incident

I'm going with secret nuclear testing. I don't think this was an avalanche. Internal injuries with no exterior wounds. Crushed skull and no damage to exterior skin. Doesn't sound like snow to me, even if it was alot. If they had time to dig themselves out, they had time to get dressed. This happened quick and with no warning. I don't think these people stood a chance. Too many missing pieces and too much military secrecy. I think all the top officials involved are now dead. Unless a pile of papers is found in a safe or something, we may never know the real story.
