Yeah, WAB said, that closing the area is one of the many myths around. As he argued, it is not reasonable to think, you can just "close" an area with the size of Belgium just like that. If I am not mistaken, the so called closing meant, that hikers could not obtain the degree in sports in the area under the usual rules, and not that people were not allowed to go there.
Size of Belgium ! ? I think not. And I think you will find that NO HIKERS went to The Dyatlov Pass for many years after the Event.
The comparison to Belgium is only illustrative, and is relative, of course.
Can`t recall seeing a case file or official register, where every trip in the area after the incident is documented by date, but it could be my bad. May be I will find, that hikers skipped it, maybe I won`t, but that is not the point anyway. The point is why. Because they were reluctant to go to a place, where a terrible tragedy happened, or because the place was “closed”.
I can hardly see, it is because someone said: "hikers are forbidden to go there for unknown period of time, because the State says so". How do you even imagine this? The Red Army put a fence and was guarding it like a border line? The KGB was observing the hiker`s routes and was preventing all enthusiasts to go there? Or between all the Soviet Tourist clubs, an official order of the day was sent from "high above", that the region where the Dyatlov group was hiking is "closed"? This is not area 51, it`s the Northern Urals. That sounds so overstretched. But I have to admit - it really fits the conspiracy narrative very conveniently.
As Loose Cannon pointed, there seems to be a way more down to earth explanation.
I think we are derailing this topic though, since it is about another incident.
