What the rescue mission saw was hard to believe: the tracks of barefoot prints were heading away from the cut open tent. During the period of several months the bodies had been located in 4 kilometers radius, some frozen to death wearing nothing but underwear or just one sock, others had their head or chest broken, eyes popped out or the tongue torn out. The mystery of Dyatlov group death remains unsolved for over 60 years.

One of them is mountaineer and traveler Teodora Hadjiyska.
