The Urals were a large situs for uranium mine retchlags, i.e. extermination camps, in the 1950s. It’s well known that radioactivity has been found on clothes of some of the victims.

In my opinion what happened is that, they went into exploration as the camps were closed because of the snow. The camps were closed but still there down under the snow. The plutogenization process in the early camps was primitive, simple pots dig in the soil where radioactive corpses were piled for plutogenization. There was an accident known as the Golden Hill blast… at that time. There is a picture of a blob of skeletons in a pit with meltdown tracks, peculiar burns, a majority of legs remaining, in particular. It’s that pit, related to harvesting of uranium on victims of the extermination.

What happened in the Dyatlov Pass case was identical. Pressure is enough to trigger a nuclear blast. They walked on a plutogenization pit that had been abandoned with the first snows and it triggered the blast. It was certainly snowless and one decided to jump on it out of curiosity.

The official investigations solely noted that an “irresistible force” led to the death of the expedition. It’s the nuclear blast triggered by their walking on a plutonium pit, that caused this.

From Wikipedia we learn that the bodies were scattered in a circle of 1,5 km width. This is explained by the nuclear blast.

In Soviet planes serious measures were taken to distract the attention of the passengers from looking to closely at the ground, perhaps especially in some known areas…
