The Dyatlov Pass Incident: 10 Theories About What Really Happened
- Why did nine experienced hikers cut their way out of their tent from the inside?
- What caused them to run barefoot into -30°C snow to their deaths?
- How did some bodies sustain injuries similar to a car crash without external bruises?
In February 1959, nine hikers disappeared in the Ural Mountains of the Soviet Union. When searchers found their camp weeks later, the scene made no sense. The tent was slashed open from the inside. The hikers were scattered in the snow, half-naked. Some had crushed skulls; one was missing a tongue.
For over 60 years, the Dyatlov Pass Incident has baffled investigators. Was it a natural disaster, a military cover-up, or something supernatural? Here are the 10 leading theories explaining the tragedy on “Dead Mountain.”
1. The Slab Avalanche (The Scientific Theory)
In 2021, a study published in Nature Communications used Disney’s Frozen animation technology to simulate snow movement. It suggested a “slab avalanche”—a small, delayed block of snow—fell on the tent while they slept, crushing ribs and causing panic. This explains the internal injuries and why they cut the tent to escape instantly.
2. Infrasound (The Madness Theory)
The shape of the Kholat Syakhl mountain creates a “Kármán vortex street” when high winds hit it. This can generate infrasound—a low-frequency hum (see our article on “The Hum”) that causes nausea, panic, and hallucinations in humans. The theory suggests the hikers were driven into a state of irrational terror by the sound of the wind itself.
3. Paradoxical Undressing
Why were they naked in the freezing cold? Severe hypothermia can cause a phenomenon called “paradoxical undressing.” As the body shuts down, the nerves controlling blood vessel constriction fail, causing a sudden flush of hot blood to the skin. The victim feels incredibly hot and strips off their clothes just before freezing to death.
4. Military Parachute Mine Tests
Another group of hikers 50km away reported seeing glowing orange spheres in the sky that night. Investigators found traces of radiation on some of the hikers’ clothes. This led to the theory that the Soviet military was testing parachute mines or rockets overhead, which either exploded nearby (causing the blast injuries) or frightened the group into fleeing.
5. The Yeti (The Menk)
The local Mansi people have legends about “Menk” (forest giants). One of the hikers’ cameras contained a blurry photo of a dark figure near the trees. While likely a distortion, cryptozoologists argue that the crushed chests—with no external bruising—are consistent with being squeezed by a large creature.
6. Mansi Warriors Attack
Early investigators suspected the indigenous Mansi people attacked the group for trespassing on holy land. However, the tent showed no signs of an external struggle (it was cut from the inside), and the footprints in the snow belonged only to the hikers wearing socks or bare feet.
7. KGB Controlled Delivery Gone Wrong
A spy novel theory suggests that one of the hikers was a KGB agent meeting a US spy to deliver fake radioactive samples (explaining the radiation on the clothes). When the meeting went wrong, the foreign agents killed the group to cover their tracks. While exciting, there is zero evidence of foreign presence in the Urals at that time.
8. The Stove Fire
A simple explanation: the makeshift stove in the tent malfunctioned, filling the small space with smoke or fire. Choking and blinded, the hikers slashed the tent to get air and ran into the snow. In the chaos and darkness, they became separated from the tent and couldn’t find their way back before the cold took them.
9. Gravity Winds (Katabatic Wind)
The region is known for sudden, violent hurricane-force winds that descend down the mountain slopes. A sudden gust could have blown the tent down or carried people away. However, footprints suggested they walked calmly (mostly) down the slope, not that they were blown.
10. Mass Hysteria / Mushroom Intoxication
Some theorize the group may have consumed local psychedelic mushrooms or suffered a collective panic attack. This would explain the disorganized behavior and the split into different groups. However, autopsies found no trace of drugs or alcohol in their systems.

Frequently Asked Questions (FAQ)
Was radiation really found on the bodies?
Yes, beta-radiation was detected on the clothes of two hikers. However, they worked in nuclear facilities, which might explain the contamination unrelated to the incident.
Why was one hiker missing her tongue?
Dubinina was found in a ravine with running water. Forensics concluded that scavengers or decomposition in the wet environment removed the soft tissue (tongue and eyes) post-mortem, rather than it being cut out.
Is the case officially closed?
Russian authorities reopened the case in 2019. In 2020, they officially concluded that a combination of an avalanche and poor visibility caused the deaths, closing the file again.
