The lack of eyewitnesses has inspired much speculation. Soviet investigators simply determined that "a compelling natural force" had caused the deaths. Access to the area was barred for skiers and other adventurers for three years after the incident. The chronology of the incident remains unclear because of the lack of survivors.
Alexei Rakitin, author of the book "Dyatlov Pass", introduces the version that Alexander Zolotaryov, Alexander Kolevatov and Yuri Krivonischenko were KGB agents on a mission to uncover a cell of CIA agents. They were to deliver radioactive samples and then take photographs of the Americans, but something went wrong and the CIA agents killed the group. It sound absurd now, but in a state of fear and paranoia this was the only way to spy on Soviet Union. Russians were not stupid either. They repeatedly fooled Western by radioactive-tainted material from places that had nothing to do with it. This brings us to so called theory of Western intelligence involvement. According to this theory two or more members of the Dyatlov group were hired by the KGB to deliver fake proof of radioactive tainted clothes. The rest of the group was probably unaware of the real purpose of their journey. Rakitin version is one which is widely spread now and is quite logical in terms of explanation of the most mysterious issues - radioactive clothes and usage of radiation detectors, gray foam on Doroshenko's face, absence of shoes and upper garments, at least 1 camera missing, etc.
In fact, it was some strange details about the skiers themselves that gave rise to a Cold War spy story scenario. Semyon “Alexander” Zolotaryov*, a 37-year-old bachelor, and instructor at a remote tourist center, joined the group at the last minute. He was a veteran with years of combatant experience who fought for the NKVD, and bore an enigmatic tattoo, “DAERMMUAZUAYA”. Until this day, the word remains un-translated into any known language. Archives of the Ural Polytechnic Institute revealed a remarkable detail about Alexander Kolevatov: before transferring to the Physics-Technical department at the UPI, he worked in Moscow as a laboratory assistant in a top-secret scientific facility, an unnamed “atomic” institute known as “P.O. Box No. 3394”. And Yuri Krivonischenko worked in a most notorious “P.O. Box*” – the plant “Mayak*” in Chelyabinsk-4010, where a massive nuclear disaster, second in severity only to Chernobyl, occurred in 1957. Researcher Aleksei Rakitin is certain that this peculiar fellowship was not gathered by a whim of chance. Behind the biographies of Zolotaryov, Kolevatov, and Krivonischenko, the brooding shadow of the KGB is distinct. The true objective of the ski trek, unbeknownst to the other seven members, was to deliver radioactive samples to a group of agents of the CIA*, and to take pictures of the spies. The latter had been under the guise of ordinary tourists camping at the Mountain of the Dead. The meeting took place on February 1st, but something went wrong, and the Americans realized that the trio was playing a double game. A conflict ensued: a fight, torture and the brutal massacre of the entire group. Thrilling as it is, Rakitin’s story did not altogether impress the friends of the Dyatlovs. Vladislav Karelin regards it as a red herring. “They were tough guys. To scare the daylights out of them you would need something extraordinary, something astonishing”.
One private investigator, who spoke to former servicemen in the area, said the hikers could have been killed after being mistaken for escaped prisoners from local Gulag prison camps. Or alternatively, that they were killed in a ‘clean-up operation’ after a series of military exercises. Siberia at the time of the tragedy was still a land of Gulag. Many political prisoners were released in 1953-56, but criminals were still behind bars. Many small concentration camps were dispersed all over the region. The closest was Ivlag situated just few miles from a site of a tragedy. Although it is true that there were no escapes around the time of the tragedy it doesn't mean that it never happened before. History knows many examples then prisoners would escape and go into hiding for years and even decades at a time. They could have easily missed death of Stalin in 1953 and subsequent amnesty to all political prisoners. Young tourists could be taken for unwanted witnesses and subsequently killed. If you take in consideration that many of the political prisoners came straight from the fronts of the World War II it is plausible that these people knew how to kill and were open to the idea. Furthermore Yuri Yudin discovered a piece of clothing that did not belong to any of the members of the group. This "obmotki" is a wide piece of clothing that are wrapped around feet or legs to keep them warm. They have distinct shape and made from a particular material. They were widely used among the soldiers in the 40's and later among the prisoners of Stalin's concentration camps. Nobody knows how it got here and nobody knows how it disappeared from the evidence room. But it did.
Since there were no prison breakouts from the local Ivdelsky corrective labor colony, the next in line suspects for the culprit were the indigenous Mansi people living in Khanty–Mansia, an autonomous district within Tyumen Region in Russia. At the second week of the investigation the prevalent theory was that the evil Mansi hunters who often camped in Mount Kholat Syakhl committed the crime on the night of the February 1. The information we have on the Dyatlov Case can be mostly attributed to the work of St. Petersburg investigator Evgeny Vladimirovich Buyanov. What made native Mansi people strong candidates to be the perpetrator:
However, this contradiction was not of a considerable bother for the investigators, at least not in the first stage of the investigation. The temptation to "hang" the death of tourists on the local Mansi was too great. Several young Mansi hunters were were arrested in March 1959 and interrogated. It's hard to say what would have been the fate of these people, because the ability of the Soviet "machine of justice" to produce the necessary evidence is confirmed by the entire history of its existence, but the investigation in the second half of March made a surprising turn.
Fly Agaric (Amanita Muscaria) are very toxic, but they become less lethal when dried out. Conveniently, they grow most commonly under pine trees (because their spores travel exclusively on pine seeds), so the shaman would often hang them on lower branches of the pine they were growing under to dry out before taking them back to the village. As an alternative, he would put them in a sock and hang them over his fire to dry. I wonder where the Christmas socks came from.
Another way to remove the fatal toxins from the ‘shrooms was to feed them to reindeer, who would only get high from them — and then pee, with their digestive systems having filtered out most of the toxins, making their urine safe for humans to drink and get a safer high that way. Reindeer happen to love fly agarics and eat them whenever they can, so a good supply of magic pee was usually ready and waiting all winter. In fact, the reindeer like fly agarics so much that they would eat any snow where a human who had drank ‘shroom-laced urine had relieved himself, and thus the circle would continue.
When the shaman went out to gather the mushrooms, he would wear an red outfit with either white trim or white dots, in honor of the mushroom’s colors. And because at that time of year the whole region was usually covered in deep snow, he, like everyone, wore tall boots of reindeer skin that would by then be blackened from exposure. He’d gather the tree-dried fly agarics and some reindeer urine in a large sack, then return home to his yurt (the traditional form of housing for people of this region at that time), where some of the higher-ups of the village would have gathered to join in the solstice ceremony.

Svetlana Oss in her book "Don't Go There" believes that Khanty hunters who had taken Agaric Fly to get themselves in a killing mood killed Rustem Slobodin with a dynamic head kick and inflicted the chest injuries by jumping or bouncing on the chests of Yuri Doroshenko, Lyuda Dubinina and Semyon Zolotoryov. Svetlana claims, they wanted to avoid shooting so as to foil investigators which is why they sanitized the tent area covering their footprints with snow and making the cuts themselves, thereafter forcing the tourists to discard clothing and footwear which is why Dyatlov's jacket and flashlight were found outside the tent. Svetlana interprets frame №17 from Thibeaux Brignolles camera as a hunter who was following the group and was surprised when they held quietly till the stalker briefly emerge and this photo was taken before the figure retreated back into the woods. This would also explain their choice to pitch the tent away from the treeline. Zolotaryov and Thibeaux were almost fully clothed and wearing some kind of footwear. Zolotoryov was found with a camera around his neck. We speculate that the two might have gone outside the tent to relief themselves and Zolotoryov took his camera because something interesting was going on. Read more about Valentin Yakimenko's study of the the damaged negatives found in Zolotoryov's camera. Related to this theory questions are if Khanty hunters stalk them and did the Shaman interpret the unusual lights in the night sky (if there were light) as permission from the spirits to uphold their tradition that to them the mountain was sacred and forbidden to strangers, especially to women, who may not gaze upon it? Indeed had some of the group cut slit holes so as to surveil where their stalkers might be? The case of the Khanty hunters made by Svetlana Oss ends with a possible clue regarding a rifle that somebody bought from a native who implied while drinking that he witnessed the incident.
The possibility is that the group may have ingested the mushrooms, either intentionally or unintentionally, and suffered the delirium and sweating with acute doses. This would account for what appears to be the bizarre behavior of the group on that final night. Here is a reenactment by Sandro Demelas.
Danger of avalanche in the region is quiet common. The Kholat Syakhl mountain is not very tall and it is certainly not very steep. Furthermore the opponents of this theory suggest that tourist diaries report a fairly thin snow cover. However these facts doesn't exclude the possibility of a small avalanche. A portion of the upper layer of snow could simply shift and role over the tourists as a slab of snow. This could damage the tent and create havoc among tourists who were suddenly trapped underneath several feet of snow. It would certainly explain why the tent was cut from inside. Further retreat would be necessary if the tourists were worried a second avalanche can strike again. According to the supporters of this theory Dyatlov Group tried to make their way back to the Auspiya river and instead made a fatal mistake by descending into a valley of the Lozva river. After 4 weeks the snow that was rushed down the slope of the mountain was simply blown off by the strong winds that are common in the region. This would erase all signs of a natural disaster. However this theory has its gaps. From what we can tell from the naked footprints left by the group everyone seemed to descent with relative ease. It is highly unlikely that three people with broken ribs and flail chest would be transportable at all. And here we see several badly damaged men and a woman walk without problems or even help from any of the members of the group. Secondly these men and women were experienced and well trained. They knew that chances of freezing to death is more likely than getting killed by an avalanche. Although the removal of the damaged tent from an exposed mountain side was out of the question, they had to retrieve all their warm clothes. And finally if you see on the pictures on February 1st on the left and February 26th (according to Vadim Brusnicin who is sitting on a slope of the mountain with his back toward the camera man) on the right you can see part of the tourist gear that kept its vertical position on the slope weeks after the tragedy stroke. Furthermore the entrance of the tent is clearly elevated. Only the middle portion collapse probably due to hasty escape or weigh of snow simply collecting here.
Occasionally some of the conspiracy theorists claim that UFO scared the group away. Although seemingly incredible this claim might have some base to it. About the same time Soviet armed forces did launch several rockets from Baykanur base. Although military claimed the rockets landed in the north Ural mountains, several geologists 70 km from the mountains saw some glowing and pulsating orbits flying in the direction of the Kholat Syakhl on a day of tragedy (evening of Febrauary 1st).
Lev Ivanov, a man who was in charge of the investigation at the Dyatlov Pass, lived a long life. In the early 1990's in an interview to a local journalist he made a statement that during his investigation he and E.P. Maslenikov both noticed that the pines in the forest were burned at the top. He also claims that A.P. Kirilenko, member of the Soviet Congress, along with his advisor A.F. Ashtokin forced Ivanov to take out any reference to the unknown flying objects or other strange phenomena. This included pictures of flying spheres drawn by the Mansi hunters and other testimonies. It is true that Soviet Union experienced a boom of interest on everything unknown. Skeptic might also add that Ivanov gave this interview to make some money. However we have to mention that Kirilenko became obsessed with UFO theme. Starting in the early 60's he filed several requests to gain access to the KGB archives. We don't know what was found in the documents, but it is undeniably strange that a political figure in USSR paid such interest in this subject. UFO was not investigated by the official science so it deemed as a pseudo- religious phenomena. Atheist Soviet Union obviously prohibited any interest in the subject, especially among members of the highest legislative body in the country.
Surprisingly, one of the most extraordinary and astonishing versions came from none other than Lev Ivanov himself. In 1990, the retired Prosecutor published an article, “The Enigma of the Fireballs”, where he admitted that in spring of 1959, under the pressure of A. P. Kirilenko, and of his deputy, A. F. Yeshtokin, he withdrew various key materials from the case that indicated the true cause of the accident: “fireballs” or a UFO*.
“When E. P. Maslennikov and I examined the scene in May, we found that some young pine trees at the edge of the forest had burn marks, but those marks did not have a concentric form or some other pattern. There was no epicenter. This once again confirmed that heated beams of a strong, but completely unknown, at least to us, energy, were directing their firepower toward specific objects (in this case, people), acting selectively.”
It is worth noting that later on, Kirilenko professed a lively interest in the UFO’s, and received memos about sightings of unidentified objects from the Chairman of the KGB, Andropov.
The celestial phenomena that accompanied the Incident almost convinced everybody that the skiers’ lives had been sacrificed to the new Soviet idol – the rocket. In the criminal case, there is a radnote of particular interest, sent to the headquarters of the search party:
RADIOGRAM TO SULMAN
3/2-59 yr. — 18:30
[…] the main mystery of the tragedy remains the exit of the entire group out of the tent […]
The reason could be any extraordinary natural phenomenon, such as the flight of a meteorological rocket, OBSERVED ON THE 1st OF FEBRUARY IN IVDEL and by Karelin’s group [stop]
Tomorrow we will continue the search [end]
A vague evidence of the “rocket version” once managed to reach Vladimir Korotayev:
“Many years later, I talked to some scientists from Korolyov’s circle, the office of academician Rauschenbach, to be exact. It was hinted to me that, so they say, there were some tests being done.” All the requests sent to various launch sites by researchers, however, yielded no results: there had been no rocket launches in the Soviet Union from the 1st to the 2nd of February. Perhaps, the relics and stigmas of the rocket cult can be found in the Sverdlovsk taiga? Since the time of the search party operation, there were rumors of a secret training ground located somewhere near the site of the accident. Locals still relate legends of meetings with military patrols in the middle of the taiga, holes in the hillsides sealed with concrete, and the sound of a train that comes from under the ground in the woods.
A 2008 conference at the Ural State Technical University, together with the Dyatlov Group Memorial Foundation, decided military testing was to blame. The Federal Security Service responded that all those involved in the case had long since died.
As part of technological theory there have been suggestions that an infrasound might have been responsible for sudden unpleasant feelings among the tourists. New research into rare weather phenomena has suggested that a 'perfect storm' could have struck the campers in the night, panicking them so much that they would have fled the tent, and fallen victim to the brutal cold before they came to their senses. Donnie Eichar, who spent five years researching the incident, and undertook the dangerous trek himself, believes that a wind phenomenon called a Karman vortex street could have produced a terrifying, powerful sound which is proven to induce irrational fear in humans. Due to the unique topography Dead Mountain (all mentions of Dead Mountain instead of Mountain of the Dead refer to Donnie Eichar's book), which is a perfect dome shape, the fierce winds that blow through the pass could have been warped as they struck the blunt surface. The wind, which was blowing in a straight line, would be twisted into a series of small but powerful tornadoes which would tear down either side of the pass. The tornadoes, spinning fast enough to tear the roofs off buildings, would have created a deafening noise, even if they missed the tents, as Eichar's theory suggests. But under certain circumstances they could also produce a more subtle and terrifying phenomenon known as infra-sound. The opposite of ultrasound, infra-sound is a type of vibration in the air which has a frequency so low it cannot be picked up by the human ear. But a succession of studies has shown that it can have marked effects on the human body, including loss of sleep, shortness of breath, and extreme dread. Eichar, backed by scientists at the National Oceanic and Atmospheric Administration in the U.S., believes that the combination of the effects on infra-sound, the deafening noise of tornadoes, and the claustrophobic, pitch black tent could unseat even the most steady-minded adventurer.
Though the science sounds incredible, Eichar believes it is the only logical explanation for the situation in which the bodies were found. Although Dead Mountain is so remote and inaccessible that the weather phenomenon cannot be directly observed there in the winter, it has been observed in similarly-shaped locations, including the rock of Gibraltar and an array of other peaks.
In the right conditions, a flow of wind can be directed in such a way that it creates a vortex. These vortices are created in sequences by the moving air, and travel away in a fan shape. With sufficiently high winds and the correct angles, these vortices of wind could form powerful tornadoes, with the potential to emit large amounts of infra-sound, as well as cause damage by themselves. Eichar's theory supposes that the Dyatlov hikers' tent was directly down wind from the peak of the mountain, and far enough away that the whirling winds themselves did not strike the tent. But they would have been close enough for the effects to be felt – and heard.
Infrasound, vibrations in the air which are too low for humans to hear, was first observed in the 1960s. The waves, defined as anything below human hearing range of 20 hertz (the upper range is around 20,000), can be made by man-made objects as well by natural phenomena. Vladimir Gavreau, a French scientists, first noticed the effect of infra-sound on his body thanks to a badly-designed fan. When his lab assistants began suffering nausea for no obvious reason, he discovered that the discomfort was cause by the motor of a large fan, which was emitting the sound waves. A 2003 study in the UK found that a fifth of people exposed to infrasound reported feeling anxious, scared or unable to breathe properly. Another theory holds that the waves are linked to ghost sightings. Eichar's hypothesis for the Dyatlov pass holds that the whirling tornadoes would have been able to produce infra-sound in sufficiently high levels to induce panic in the slumbering hikers, after which the Siberian weather did the rest.
These are only few of the theories. Many are more bizarre, strange and quiet frankly dumb ideas that circulate out there. Some blame the spirits others blame the paradoxical undressing that lead to hypothermia. All these theories ignore the fact that only two bodies showed signs of undressing after they left the tent. And it was the first two bodies found under the cedar. Their clothes were removed after they died. We can assume the bodies were beginning to show first signs of rigor mortis or stiffness after death. The clothes of dead victims were cut off and later found near the bodies in the den. This proves that people were aware of the danger of hypothermia and tried everything they could to save themselves. Why did they leave the tent with all the clothes and boots inside is still a mystery. Many theories surfaced in the past decades. Few of these, however, explain a wide range of physical injuries that the group experienced.
Unfortunately these were not the last victims of the Kholat Syakhl. From 1960-61 several airplane crashes took away lives of nine pilots and geologists who were sent here. For a time flights were totally canceled in the region. Among more recent victims of the mountain was a crash of Mi-8 in 2009. Pilots ignored long standing unofficial no- fly zone. Fortunately they survived the cash, but they couldn't explain why their helicopter went down so quickly and without any warning. Tourists today repeat the track of the Dyatlov group, but none of groups ever contain 9 people. In the early 2000's a group of 9 tourists under supervision of rescue crew repeated the same descent down the slope of Kholat Syakhl. Despite snow cover and night time none of the participants got any significant bruises or cuts. Those who observed the students did not report any difficulty in locating members on the mountain side. None of the group members were lost and vocal/ eye contact was constant between group members at all times. This only adds to the mystery of what really happened on Kholat Syakhl that day. The case of Dyatlov Pass deaths remains open.
Discovery Channel “documentary,” Russian Yeti: The Killer Lives makes a sensationalist hash out of a genuine historical mystery—the tragic deaths of nine hikers in the Ural mountains in February of 1959. Known as the “Dyatlov Pass incident,” this unsolved cold case has unusual aspects that give it something of an air of the inexplicable, leading to the rise of conspiracy theories and paranormal speculations. Notably, though the bodies of the hikers were eventually recovered by a search party, they were found scattered over a large area in states of partial undress, as though they had fled their tents in the night in a panic. Perhaps, some speculate, they were running from someone—or something? Cue X-Files theme.
I shouldn’t snark. It’s ghoulish to make hay from the untimely deaths of other people—in this case, people who have surviving loved ones today. But mystery-mongering television programs have rarely found a tragedy they weren’t willing to exploit—and distort.
Russian Yeti: The Killer Lives caps a marathon of Discovery monster hoaxes (both of their infamous and profitable mermaids hoaxes and last year’s Megalodon hoax are playing again earlier today). In this program, hosts Mike Libecki and Maria Klenokova set out to solve the Dyatlov Pass incident—or rather, to pretend on air that it had something to do with the Yeti.
For a detailed critique of the program’s claims, see this useful analysis over at Doubtful News. Short version: we don’t know what happened to those poor people, but it’s easy to posit completely plausible explanations which fit the facts. The party may well, for example, have fled from what they believed was an imminent avalanche.
Tragic, plausible scenarios are in ready supply. They’re just not good television.
You know what is good TV? Monsters. Huge, terrifying, tongue-eating monsters. (Much is made of the assertion that one hiker was missing part or all of her tongue — plausibly bitten during a fall, skeptics suggest, though her body was also found with other presumably post-mortem soft-tissue damage — almost inevitable after weeks of exposure in the forest.) Never mind that we have no particular reason to suppose that the Dyatlov Pass case involves Yetis in any respect (nor, for that matter, aliens, vampires, or griffins). Never mind that Yetis are probably best thought of as a modern myth, as Don Prothero and I discuss in our book Abominable Science! When it comes to the paranormal, media producers are delighted to untether themselves from all responsibility. For all the investigative posturing of programs like Russian Yeti: The Killer Lives, the producers will sacrifice anything — facts, plausibility, dignity, a respected television brand — in the pursuit of a ratings monster.
How can you construct a two-hour special about Yetis around a case that has nothing to do with monsters at all? How can such vivid tapestries be woven from such insubstantial stuff? Tabloid television’s traditional filler techniques are the pregnant question, the bald declaration, and the provocative non sequitur. Russian Yeti: The Killer Lives makes generous use of all three.
“When I found out one of the students was missing a tongue immediately I knew this was not caused by an avalanche. Something ripped out the tongue of this woman,” Libecki flatly declares near the beginning of the program. Turning to a Soviet-era Yeti expedition, the narrator asks ominously, “why do so many files related to the expedition remain classified?” I don’t know, because the show neither explains it nor demonstrates that any such files are classified at all. Citing one man’s decades-old recollection of having seen a military-style boot cover (a gaiter) in the vicinity of the disaster, the show leaps to the claim that “Somehow the military reached the crime scene before the search party. Yet there is no official record of any military presence in the area when the hikers died — begging the question, was the yeti expedition actually ended?” Begging the question indeed.
This show about Russian history declines to interview any Russian historians. Instead we’re treated to interviews with cryptid proponents Jeff Meldrum and Igor Burtsev. But this sort of cable mystery-mongering does cryptozoology few favors. Burtsev complains that the production came to him with a preconceived agenda:
I was interviewed by [Russian Yeti: The Killer Lives director] Neil Rawles too. I understood that he was making a program to fit the solution of the puzzle under the ready answer. And he tried to get from me the same answer about fault of the yeti in group’s death. For this he was shooting me for many times asking only one question: could be yeti a reason of the death? But I couldn’t agree and rejected that…
The central showpiece of the program is a black and white still photograph showing a dark, unidentified figure standing in the trees. It is introduced with stark onscreen text: “The following image is one of the last photos taken by the hikers. It is being shown on television for the first time.” This picture is presented as evidence that a Yeti was stalking the doomed party through the woods — their inhuman killer caught on film. What are we to make of this “extraordinary photographic evidence”?
To begin with, it doesn’t look much like a Yeti. With its short, rather thin arms, it looks a lot like a person in a coat. Its very lameness as Yeti evidence may be the best sign of its possible authenticity — authenticity as a photograph taken during the expedition, that is. (Probably a photograph of a member of the party.)
But the faked footage and invented on-air “scientists” of previous Discovery / Animal Planet hoax “documentaries” leave us little choice but to consider other, more cynical possibilities when viewing programs of this type on Discovery’s networks. Could the photo have been created for the production? How much of this “documentary” was simply made up from whole cloth? Libecki appears to be an actual person, at least — unlike “Dr. Paul Robertson” of Mermaids: The Body Found and Mermaids: The New Evidence, who was a fictional character played by Canadian game designer Dave Evans. (For more, see my 2013 Junior Skeptic story on mermaids inside Skeptic Vol. 18, No. 3.)
“No doubt it’s one hundred percent real,” Libecki says of the haunting photograph, explaining that it was included within the original, uncut negatives. Yet such is Discovery’s tattered credibility on such topics that we can’t take even the simplest facts for granted.
The rough cut I saw ends with the disclaimer, “This program contains elements of dramatization.” Yes — but how many? Reading this and thinking of Mermaids: The Body Found’s vague, blink-and-you’ll-miss-it disclaimer that “certain events in this film are fictional,” I can only reflect on the damage Discovery’s phenomenally successful hoaxes have done to their once trusted nonfiction brand — at least for me.

Discovery’s Mountain of Mystery Mongering: The Mass Murdering Yeti - Benjamin Radford, Skeptical Inquirer
"Now we know snowmen exist" - a hoax that this theory was based on
An apocryphal 2013 horror film, Devil's Pass, ran roughshod over the facts and suggested a ghoulish teleportation experiment – and its elite guards – had put an end to the Dyatlov hikers.
This theory is presented by Nigel Evans himself in the discussion section of this site.
"The tent slits, hot spot near the tent and a camera on a makeshift tripod suggest that they were observing something in the sky. Given that the local Mansi people blamed the golden orbs for the tragedy and the repeated sightings of lights in the sky from reliable witnesses in the same period together with photos from the group's cameras possibly of aerial lights, it is plausible that the group fled from the tent due to an occurrence of ball lightning  getting very close to the tent and hovering there melting the snow beneath to create the hot spot. The group then hurried to the treeline 1500 meters away and lit a fire whilst they waited for the object to disappear. The theory then describes how the two deaths at the cedar were due a single electrocution event (due to normal lightning strike or ball lightning) creating burnt hair, bleeding head orifices, large burns, burnt clothing, pulmonary edema and tree damage and the subsequent four deaths in the ravine due to an explosion event near to the den (again due to a more powerful lightning strike or ball lightning). Although cold weather lightning is rare it is possible see . The theory suggests that the ravine lightning strike hit close to the den and vaporized a substantial quantity of stream water, snow and ice (positive polarity strikes -  can produce 300,000 amps and temperatures several times hotter than the surface of the sun, e.g. 30,000C) creating an explosion amplified by the confines of the ravine that threw the den and it's occupants 6 to 10 meters resulting in blunt force injuries similar to a car accident or barotrauma. The theory suggests that the three surviving members died in two groups, Rustem Slobodin was injured and urgently had to be returned to the tent assisted by Zinaida Kolmogorova. Due to snow drifts and high winds he collapsed on the journey and Zinaida Kolmogorova also further on due to the same plus exhaustion from the effort of assisting him. Igor Dyatlov remained with the ravine four as Lyudmila Dubinina and Semyon Zolotaryov although badly injured stayed alive for some time afterwards and Nikolai Thibeaux-Brignolles was unconscious. Igor Dyatlov may have stripped the two bodies at the cedar (turning the bodies) to provide more insulation for those still alive and possibly contributed some of his own. Some time later he decided to abandon his vigil and return to the tent but died being the only member of the group to have clear signs of hypothermia. Police officer Lev Ivanov, who led the official inquest in 1959, apparently favored the fireball theory."

"Why would they leave the tent? I would argue that the only thing that could make them leave would have to be an immediate thread inside the tent. if something was outside, such as an animal or a UFO, then there would be no reason to cut the tent open. There were no signs of an avalanche, however, they could have excaped believing an avalanche was tumbling towards them. The problem with that theory is that the footprints showed them walking in a calm and orderly manner down the slope as opposed to running away in panic. So something caused them to panic inside the tent but once outside they calmed down and made a conscious decision to walk down the slope. Their external stove was a completely unique and homemade design as the leader of the group had built the stove himself. We know they had used the stove on the night of the incident before the incident took place as partially eaten pieces of fried ham and bacon were found inside the tent. I think that after dissassembling the stove and removing the exhaust pipe, the embers inside the stove were accidentally reignated. As the exhaust pipe had been removed, the smoke would have filled the tent in seconds. As they attempted to get control of the flame they cut a few holes at the top of the tent to vent the smoke. When that didn't work and it became increasingly difficult to breathe, the side of the tent was slashed open and they all escaped in a state of panic. The burn marks on their bodies and clothing could have been from the scolding hot metal stove. Several member sof the group were found with blood around their mouth and coughing up blood could be a symptom of a smoke inhalation. Some of them were intoxicated which could've effected their judgement as well as their sensibility to the cold."
There are no facts to support that there was cooked food or that anybody was intoxicated. The goup carried vodka but no empty bottles were found.
Russian scientists believe that tourists came to the area where under certain circumstances the force of gravity can fluctuate. Petersburg physicist, Ph.D., Associate Professor of Institute of Engineering and holder of more than one hundred patents German Erchenko believes that the significantly decreased external pressure threw the hikers out from the tent.
Scientists have long studied thermodynamics, hydrodynamics, various aspects of the nature of gravity and weightlessness of bodies. He believes that Dyatlov tourists came to the area, which at the confluence of circumstances can have significantly decreased force of gravity. "It formed a corridor of a kind, in which Earth's gravity decreased. The tourists in the tent - sleeping or just getting ready, had time to undress. And then "unknown force" began to lift them up off the floor and drag them into the direction of the corridor", said the scientist. As the outside air pressure was significantly lower than inside the tent, "people began to push outwards", the scientist said. "The emerging tourists instantly pushed the tent from the inside, and since the pressure in their bodies still remained high, they received "unexplained" internal injuries - including broken bones.
"Some of the tourist died instantly, others remained alive for some time, but the bodies once outside the tent remain hovering in the air as though lying on a horizontal surface. In this position same force pulled them to the side", said the physicist. According to Erchenko's calculations, the phenomenon lasted only a few minutes. This period of time was enough to throw people in 1-1.5 kilometers distance. "They flew one by one or in groups from the tent, to be scatter on the slope and in the woods. When they were falling in the snow from a height, not being able to protect themselves, they received the injuries on their faces, which were disfigured", adds Erchenko.
