Welcome to Mystery Date. In Season 1, we’re venturing deep into the forest—real ones, haunted ones, and in this case, frozen Russian ones—with stories that start out like fairy tales and end like forensic files.
This episode takes us into the heart of one of the most enduring mysteries of the 20th century: The Dyatlov Pass Incident.
Part 1: Setting the Stage
In this episode, we walk us through the timeline—what we know, what we think we know, and what doesn't make any damn sense. Kate reacts in real time, offering questions, commentary, and a healthy dose of skepticism. We explore the hikers’ last known movements, the discovery of the site, and the first wave of confusion that would turn this tragedy into a 60+ year mystery.
You’ll leave this episode with more questions than answers—but that’s half the fun, right?
A Journey Begins
In January 1959, ten experienced hikers—students and recent graduates of the Ural Polytechnical Institute—set off on a skiing expedition into the Ural Mountains. Their goal? Reach Mount Otorten, a remote peak in the Sverdlovsk Oblast. Led by 23-year-old Igor Dyatlov, the group was aiming to complete a route difficult enough to earn them the highest level of hiking certification available in the Soviet Union.
Meet the Dyatlov Group
Before everything went sideways on the slopes of Dead Mountain, they were just nine friends and classmates chasing adventure and a hard-earned hiking certification. Each had their own story, quirks, and reasons for joining the expedition. Here’s a quick introduction to the Dyatlov Nine—the people behind the mystery.
Igor Dyatlov – The Leader (Age 23)
A fifth-year radio engineering student and the expedition’s organizer. Smart, methodical, and known for his leadership, Igor was respected by everyone on the trip. He designed much of the group’s gear himself and had a reputation for keeping cool under pressure. If something went wrong, Igor was the guy you'd want in charge.
Zinaida Kolmogorova – The Spark (Age 22)
Energetic and kind, Zina was one of only two women on the trip. She had completed similar treks before and was known for her resilience and sense of humor. According to diary entries, she kept spirits high even when the weather turned grim.
Lyudmila Dubinina – The Tough One (Age 20)
A civil engineering student with a no-nonsense attitude and a strong will. On a previous expedition, she’d taken a stray bullet from a hunter—and kept hiking. Fiercely intelligent, Lyuda also kept detailed records of the group's activities in her journal.
Rustem Slobodin – The Marathon Man (Age 23)
An athletic and slightly introverted fellow who ran long distances for fun. A mechanical engineer and a calm presence, Rustem was often found deep in thought. His injuries were among the most mysterious, showing signs of blunt force trauma without external wounds.
Yuri Doroshenko – The Fireball (Age 21)
Brash, bold, and fiercely loyal. Yuri once chased a bear off a previous expedition—barehanded. He was known for his high energy and sometimes reckless bravery. He died wearing only a vest and underwear, found beside a makeshift fire under a cedar tree.
Alexander Kolevatov – The Analyst (Age 24)
A quiet, sharp-minded student studying nuclear physics. He had previously worked at a top-secret lab in Moscow, which later fueled conspiracy theories. Alexander’s academic focus and cool demeanor balanced out the group's more expressive personalities.
Nikolai Thibeaux-Brignolles – The Gentle Giant (Age 23)
Charismatic and charming, "Kolya" came from a French-Russian background. Known for his good looks and easygoing attitude, he was also the strongest physically—a trait that makes his fatal skull fracture all the more puzzling.
Semyon Zolotaryov – The Mystery Man (Age 38)
The outlier. Older than the others and a war veteran, Semyon joined the group at the last minute. He was aiming for the same certification but didn’t know the others beforehand. His body was found with severe chest trauma and strange tattoos, and he’s been the source of endless speculation ever since.
Yuri Krivonischenko – The Joker (Age 24)
A joker and a goofball with a background in engineering and experience working at a nuclear facility involved in the Kyshtym disaster. His light-hearted nature often diffused tension, and he was close friends with Doroshenko. His body was found with burned hands, possibly from trying to keep the fire going.
Yuri Yudin – The Survivor (Age 21)
The only member of the group who lived to tell the tale—but only because he didn’t finish the journey.
Yuri Yudin was a geology student and close friend of several hikers on the trip. He suffered from chronic joint pain and turned back early on January 28 due to sciatica and illness. It was a heartbreaking decision at the time—he reportedly begged Dyatlov to let him continue. But that reluctant goodbye saved his life.
Years later, Yuri would say that surviving the Dyatlov expedition haunted him. He spent much of his life trying to make sense of what happened to his friends. He even worked with researchers and investigators, providing insight into the group dynamics and gear, and visiting the site again later in life. He died in 2013, still searching for answers.
Yudin’s presence reminds us that this was never just a mystery—it was a loss, deeply personal and enduring.
The Journey into the Mountains
The expedition began with high spirits and cold air.
On January 23, 1959, the Dyatlov group departed from Sverdlovsk (now Yekaterinburg) by train, carrying everything they’d need for a 2-week trek into the frigid Northern Urals. Their destination: Mount Otorten, a remote peak in the Komi Republic, reachable only by ski and sheer determination. The trip was designed to earn them a Grade III hiking certification—the most challenging available at the time in the Soviet Union.
They traveled by train, truck, and finally by foot, passing through the small village of Vizhai—the last settlement before the wilderness swallowed them whole. Along the way, they joked, took photos, played mandolin, and wrote in group diaries. Their notes are filled with sarcastic entries, teasing each other about snoring, bad cooking, and the cold.
On January 28, one member, Yuri Yudin, fell ill and was forced to turn back. The remaining nine pressed on, strapping on skis and heading north toward the uninhabited backcountry. According to diaries and undeveloped film recovered later, morale remained high even as weather conditions worsened.
They were supposed to reach Mount Otorten by February 12. When no telegram arrived, families weren’t immediately alarmed—delays on remote treks were common. But by February 20, with no word and mounting anxiety, a search party was mobilized.
The Final Camp
The hikers’ last known camp was discovered on February 26, halfway up the eastern slope of Kholat Syakhl—a name that translates from the local Mansi language to “Mountain of the Dead.” Oddly, instead of continuing further into the forest where they would’ve had shelter, the group had set up their tent in the open, on a windswept ridge.
No one knows exactly why. Some speculate they lost daylight or visibility. Others believe they intentionally camped there to train for harsh conditions. But the decision would prove fateful.

A Discovery in the Snow
Weeks later, search parties found their abandoned tent on the eastern slope of Kholat Syakhl, a name that translates from the indigenous Mansi language to “Dead Mountain.” The tent had been cut open—from the inside. The hikers’ belongings and shoes were still there. Tracks led downhill into the forest, some barefoot, others in socks.
Then they found the bodies.
Two were found near a small campfire under a cedar tree, stripped to their underwear.
Three more were discovered between the tree and the tent, seemingly trying to crawl back.
The last four were found months later in a ravine, buried under snow, with traumatic injuries—including fractured skulls, broken ribs, and in one case, a missing tongue and eyes.
Despite the severity of the trauma, there were no external wounds. One of the hikers had injuries comparable to being hit by a car—but without bruising or lacerations.
Some of their clothes had traces of radiation.
And no one had any answers.
Who Were the Dyatlov Nine?
These weren’t reckless thrill-seekers. They were disciplined, detail-oriented students—engineers, athletes, and outdoorspeople. Through diary entries and photos recovered from the hike, we get a glimpse of their personalities, their jokes, and their excitement. Their last days were marked by camaraderie, not fear.
It makes what happened next all the more haunting.
