The darkest and most terrible mystery of Central Ural history. For almost fifty years, people have been vainly struggling with its clue. On the night of February 1 to February 2, 1959, in the far north of the Middle Urals on the Mansi Mountain of the Dead, an unknown and monstrous force completely destroyed a tourist group of students of the Ural Polytechnic Institute.
