The death of Dyatlov's tour group is an event that allegedly happened on the night of February 1 to 2, 1959 in the Northern Urals, when a group of tourists led by Igor Dyatlov died under unclear circumstances. The conclusions of professionals - tourists and climbers, with some discrepancies in assessments, generally boil down to the fact that for some reason on the evening of February 1 or at night from February 1 to 2, spending the night in a tent on a treeless mountainside, members of the group They left the tent in a hurry and moved down the slope towards the forest. Some people left without clothes, without shoes, without getting necessary things and equipment from the tent, and not wearing all their outer clothing. It is this fact - the reason for the group leaving the tent - that represents the main question in this tragedy. Many versions of the reasons that prompted the group to leave the tent have been expressed, and each has its own weak points. There are also a certain number of super unusual, unexplained features noticed during the autopsy: for example, the subtle purple hue of clothing, Dubinina's and Zolotarev's missing tongue and eyeballs, the strange skin color of the victims, or the fireballs that witnesses spoke of. I bookmarked it in preparation. to understand the circumstances of the death of Ural tourists. It turns out that there are so many resources and materials that you can drown. But the main difficulty, as I am beginning to understand, is not in the muddiness of the topic or even in the riddle itself, but in a completely different circumstance that makes my task hellishly more difficult. Okay, more on that later. So, on the agenda is the secret of the Dyatlov group. Let's try to solve this charade - of course, using the means available to us.
