0:00 The hikers’ tent was found on the slope of Kholat Syakhl, sliced open from the INSIDE.0:07 Last week, examining the Black Dahlia, we confronted the horror one person can inflict on another; this week, the horror is that we don't know if the killer was a person, a place, or something else entirely.0:24 The case file is sixty-three years old.0:27 I’ve never stopped thinking about it.0:30 February 1959.0:32 The northern Ural Mountains.0:34 Nine experienced Russian hikers, led by Igor Dyatlov, set up camp for the night on a mountain slope.0:42 They were young, strong, and they knew what they were doing.0:47 They never came back.0:49 When the search party found their tent, it was abandoned.0:54 Their belongings—their money, their gear, their food—were all there.1:00 But the tent was empty.1:01 The hikers were gone.1:03 Footprints led away from the tent, downhill, into the treeline.1:09 Some were barefoot.1:10 Some wore only socks.1:12 In weather that was thirty degrees below zero.1:16 The first bodies were found near the remains of a small fire, under a large cedar tree, almost a mile from the camp.1:25 They had died of hypothermia.1:28 Simple.1:28 Tragic.1:29 But then, searchers followed the tracks further.1:33 Three more bodies were found between the cedar and the tent, in poses that suggested they were trying to return to camp.1:43 And for two months… that was it.1:46 Five bodies accounted for.1:48 Four still missing.1:50 Then, in May, after the snows began to melt, they found them.1:55 The last four hikers were discovered in a ravine, buried under more than ten feet of snow.2:02 And this is where the case file breaks.2:05 This is where it stops making sense.2:08 These last four hikers did not die of hypothermia.2:13 Nikolai Thibeaux-Brignolle had a fractured skull.2:17 Alexander Zolotaryov and Ludmila Dubinina had catastrophic chest fractures.2:23 A doctor at the scene compared the force required for these injuries to that of a high-speed car crash.2:32 And yet, there were no corresponding external wounds.2:36 It was as if they had been crushed by an immense, invisible pressure.2:42 And Ludmila Dubinina… was found without her tongue.2:46 So what does it all add up to?2:49 The Soviet investigation was swift and opaque.2:53 They closed the case, ruling the cause of death was a “compelling natural force.” They sealed the files and barred entry to the area for three years.3:05 That explanation has never been enough.3:08 For decades, the most common theory was an avalanche.3:13 But the slope was too shallow.3:15 Rescuers saw no signs of one.3:18 But then, in 2021, a new scientific study proposed a specific, rare kind of avalanche.3:25 A delayed slab avalanche.3:27 The theory goes like this: The hikers cut into the snowpack to pitch their tent, destabilizing it.3:35 Hours later, in the middle of the night, a slab of heavy snow gives way and slides down onto the tent, causing the crushing injuries and inducing a state of panic.3:49 It explains the flight.3:51 It explains the internal trauma.3:53 It’s the cleanest theory we have.3:56 But it doesn't explain everything.3:59 WHY were some of the bodies so far from the tent?4:03 Why would they run downhill, away from their shelter?4:08 And an avalanche does not remove a person’s tongue.4:12 Other theories try to fill the gaps.4:15 Secret military weapons tests, fueled by witness reports of strange orange orbs in the sky that night.4:23 Infrasound—wind creating a low-frequency noise that drives people mad.4:29 Even a Yeti.4:30 But there is no evidence.4:32 Nothing solid.4:34 Just speculation trying to paper over the cracks in the story.4:39 Every theory you apply to the Dyatlov Pass incident eventually breaks against one of the facts.4:47 An avalanche doesn't explain the missing tongue.4:51 A military cover-up doesn't explain why the bodies were left to be found at all.4:57 The evidence points in a dozen different directions at once.5:02 It's a puzzle where the pieces come from different boxes.5:07 The only certainty is what happened on that slope was a heroic struggle.5:13 A struggle against something that remains, to this day, locked in the cold.
