On the Trail of the Dyatlov Group

The death of Igor Dyatlov’s hikers group is an event that presumably occurred on the night of February 1–2, 1959, in the Northern Urals—when, under unclear circumstances, a group of tourists led by Igor Dyatlov died. The conclusions of professionals—tourists and climbers—despite some differences in their assessments, generally come down to this: for some reason, in the evening of February 1 or during the night of February 1–2, while sleeping in a tent on a treeless slope of a mountain, the group members hurriedly left the tent and moved downhill toward the forest. People went out partly without dressing, without shoes, not taking the necessary items and gear from the tent, and not putting on all their outer clothing. This fact—why the group left the tent—is the main question in this tragedy.
Many versions have been proposed for why the group left the tent, and each has its weak points. There are also certain unusually strange, unexplained features noted during the autopsy—for example, a barely noticeable violet tint of clothing, the absence of Dubinina’s tongue and her eyeballs together with Zolotaryov’s, the strange color of the skin of the dead, or “fiery balls” reported by witnesses.
I’m making notes, preparing to understand the circumstances of the death of the Urals tourists. As it turns out, there are plenty of resources and materials—one can drown in them. But the main difficulty, as I begin to understand, is not the cluttering of the topic, and not even the mystery itself, but something else entirely—an additional circumstance that makes my task devilishly harder. All right, we’ll talk about that later.
So, on the agenda is the mystery of Dyatlov’s group. Let’s try to solve this puzzle—with the means available to us, of course.
