Really interesting video. After seeing Dead Mountain, it did seem like natural causes for the deaths weren't as ridiculous as I'd originally thought. But how can we know for sure there was a blizzard on 1079 on Feb. 1 through 2nd? Reading through Igor's diary that he wrote the same day, he says they are following the trail of a hunter who went ahead of them, who didn't follow the beaten trail but took his own route. So, we know for a fact that there were other people on that mountain fighting the same elements and I highly doubt only 1 other hunter was in the vicinity of the 9 that day. Igor's diary entry is confusing at times. In one place he says that when they emerged from the tree line, the wind is warm and westerly, not strong but then in his last sentence he talks about a piercing wind. Like all other theories, while it's possible a blizzard blew in that night, I still think they were experienced enough hikers who would know how to handle a basic situation like that. These kids were Siberian. What we consider cold (in NYC) was probably bikini weather for them. They're not going to run naked and screaming into the night because of snow.
