The fundamental problem with the Dyatlov pass deaths, is that no proper investigation was ever made. When the Dyatlov group's camp was found, nobody thought about securing evidence. In addition, it is certain that during the long period from the fateful night of February 1-2 and February 26 important evidence must have disappeared. Ski trails, and in particular ski trails left by mountain skis, would almost certainly have completely disappeared.
On top of the already serious difficulties mentioned above, there came orders from governmental authorities which dictated that the case be closed with the conclusion that the nine died as a result of a combination of accident by "a compelling natural force" and hypothermia. Then we need to try to find out whether accidents, natural forces and hypothermia provide an explanation for the death of nine people during one single night. Evidently, the investigators in 1959 refrained from doing that - and they were pressurized to do so. For this reason, the official documents fail to delve sufficiently deep into the forensic evidence that was and to some degree still is available to us.
After the tragedy, the government decreed that common people were forbidden to enter the area for a period for three years. There is no rational reason why such a ban should be enforced if the official conclusions were correct. The natural terrain in that area is not particularly dangerous in any way either, so there could be no need to prevent people from entering for reasons of safety.
Today, in my opinion the best we can do is to focus on the starting point: Nine people died. Their bodies were found. Dead people tell their own tale. We must simply re-analyze the available evidence as best we can, and start with the bodies. That is the best we can do.
