WAB you are amazing with your depth of knowledge.
This must be my"flaw" about my education at three universities.
In the old days we had a very big competition when entering universities, so everyone who got there had good basic training. We did not have training for money, so we could only enter at the expense of knowledge, which had to be strictly proved directly to the professor who took the entrance exams.
Do not overestimate me, my knowledge is only in the sections that we consider. There are still many others that we do not touch. If you compare it with many participants in Russian forums on this topic, there are many others who know as much as I do.
Many in this forum, especially me, offer theories with no factual evidence. I'm trying to learn from your example.
I believe your infrasound scenario makes the most sense.
I just don't think it was artificial. There's not much man can do compared to the forces of nature. Nature has everything necessary for this: both conditions and powers and a set of phenomena.
In the case of infrasound phenomena (IS), there is a logical and continuous chain that provides explanations almost along the entire chain of events.
For example: Occurrence of this phenomenon (infrasound) at this place (the area of the pass itself above the forest border) - gradual accumulation of negative phenomena - emergence of ASC (altered state of consciousness - ASC) - escaping from the tent after the accumulation of a critical dose of exposure - since the orientation in this state was completely disrupted, the participants were in different places - some participants were injured, for example Tibo and Slobodin - further (when entering the zone of vegetation and disturbance of IS) they are in loss orientation, but begin get from the IS zone to downmount.
Other people try slowly carry Tibo to the forest zone those who are in row - the rest go down different ways, to the forest, where you can light fire and warm up - the fastest cedar (this is almost the only place where there is suitable firewood) are 2 Yura - much later there (not to the cedar itself, and not far from it) come those 4, which were then in the ravine.
Since it was cold, and the heat consumption greatly exceeded the possibility of this replenishment in clothes like theirs, they gradually lost the ability to move (from fatigue in heavy traffic) and stopped. In the high cold it is fatal because the muscles lose the ability to move and the person gradually dies. The period from the beginning of cold to dying is long, but only in the beginning it is possible to have a full state of consciousness for a short time when a person perceives the situation well. Then his consciousness is gradually lost. In those conditions the possibility to survive is measured by a few hours. If all this is laid out on the ground, then we see the full picture, which is described in the criminal case. We have no other real documents for analysis.
Unfortunately, many other theories do not have such a chain. Or there are non-existent or impossible objects attracted to events.
Exiting their tent the way the Dyatlov group did was such an irrational act. They were not in their right minds at least temporarily.
This is the Altered State of Consciousness (ASC), which is a consequence of a disturbance in the functioning of the human brain, because exposure IS occurs at "harmful" frequencies of brain biorhythms (specifically, that is -dominated Alpha and Theta-rhythm alternating and Theta-rhythm is prevail), when exposure IS enters into resonance with these frequencies.
