On March 5, one of the participants of the deceased group, Rustem Slobodin, was found under snow, thick not less than 350 mm. He lay with his belly down, arms outstretched, on one of which - the right one, the joint of the thumb was bruised. The same hand had a watch. On the head a hat, on the basis of which I believe that at the time of death, there was not a particularly strong wind, since it would inevitably blow off the cap from his head if not while alive, then when Slobodin was already dead.

This passage from DyatlovPass.com serves as evidence regarding the positions of Igor, Rustem and Zina. There has been some comment that perhaps IRZ were in fact not returning to the tent from the woods, but were doing the opposite. This arguement supposes that for uncertain reasons, IRZ left the tent either before of after the others ostensibly to find and support their stricken friends.
It is clear to me that the reason IRZ was found as they were is because they did in fact descend with all the others, but after a period of freezing weather there was some improvement. This slacking of the stormy conditions made an approach to the tent a posssibility. Instead of the effort to climb the mile back to the tent giving them body heat, it drained the reserves of strength used the previous night just surviving the bad weather.
I do not believe the conditions were near pristine, but I think they were good enough for IRZ to attempt a heroic reclamation of the tent for necessities and perhaps supplies to carry back to their friends. Biology is remarkable in what people can do when they put their mind to a task. Nature has no feelings, nor sympathy for heroisms. The rule is the strong survive. Strength is not necessarily physical strength, it could be fortitude. It is no guarantee. Bad things happen to good people.
In summary, IRZ were in fact returning to the tent in arguably better weather than when they left.
