In 1959, This Was the Last Picture They Took. What Happened Next Is One of the Most Horrifying Stories

On the night of February 2, 1959, 10 skiers went on a winter adventure to the Ural Mountains, an ancient range in Russia. Nine of them never returned. It’s a story that has come to be known as the Dyatlov Pass Incident, named after the groups leader, Igor Dyatlov.

And it’s one of the world’s most horrific unsolved mysteries.

The incident occurred on the Eastern Side of Kholat Syakhl, whose name literally translates to “Mountain of the Dead.”

Fortunately, for the 10th member of the party, Yuri Yudin, he was forced to back out early into the voyage due to an illness. Considering the fate that his friends suffered, we’d consider him one of the luckiest people on Earth.

A month after the group went missing in the wilderness, investigators went in search of them, hoping they’d successfully find at least a few alive. They were wrong.

The seven men and two women, all of whom were experienced hikers and in great shape, were found dead. It was determined that they had been forced from the safety and warmth of their tent in the middle of the night and fled on foot in the snow. Despite the fact that their corpses showed no signs of struggle, the internal injuries two of the victims suffered stumped Soviet authorities — fractured skulls and two broken ribs. But there weren’t any external wounds, not even slight scratches on their skin.

Some were found fully clothed, while others nearly naked. High than normal levels of radiation were also discovered on their clothing.

What’s even more disturbing are the details of Lyudmilla Bubinina’s body. She was found with her tongue and eyes missing.

Although there have been plenty of theories as to what happened to the nine skiers, everything from paranormal activity to secret weapon tests, authorities claim that an “unknown compelling force” caused their deaths.

So, what really happened that night? Watch the video above and you decide.
