Teddy, your diagram helps me make my point. The diagram shows the tent at 880. There are identifiable prints leading away, not toward. Therefore, I find it impossible for conspirators to bring the tent up to 880 from the forest below and not leave trace evidence of their ascent. Even as I say this, you could counter me with, " Where are the tracks over Dyatlov Pass, if the hikers came that way?" But surely, the conspirators would use a sledge drawn by a pack animal to relocate both the tent and the Labaz. I doubt the geologists had this equipment, so there would be local involvement. If some local could profit by exposing the negligence of geologists, it surely would have happened. The government would have their fall guy, and the case resolved.
I find it improbable that to cover up a logging accident, the conspirators would relocate the tent to 880 and then relocate the cache that was supposedly at 880 over the ridge and down into the next valley. They do all of that and yet leave corpses around. They do all that and do not confiscate writing materials or film.
I do admire and respect you giving a measure of your young life to obtaining closure to this mystery. That said, perhaps the solution is in the written Soviet archives and a medical lab somewhere else. I am reminded that Spanish treasure ships are more readily discovered by searching the archives in Seville than by exploring swathes of open ocean.
