You might notice that
our version of events is slightly different from that stated on
other sites. The explanation is simple, while we did serious
in-depth research on the subject, many other sites (even our beloved
Wikipedia) bases their information on fictitious Russian journal
articles that often twisting the truth, made up scandalous facts and simply lied. The truth,
however, sometimes might be stranger than fiction. Dyatlov Pass
Incident is one of the these instances. In end of the article we
will mention several commonly held beliefs and facts that are wrong.
We gathered an extensive amount of information on the Dyatlov Pass
Incident including the official documents, diaries, oral testimonies
and other information. Currently, we are working on translating the
documents of the official investigation. We don't offer answers, but
we are working on providing you with the full documentation on the
case. If you have any question or want clarification feel free to

Dyatlov Pass Incident is a dramatic
and mysterious true story that unfolded in Sverdlovsk Oblast
of USSR in 1959. It occurred on the eastern slopes of Kholat
Syakhl mountain (literally "Mountain of the Dead" or "Dead
Mountain" in native Mansi language) in the Ural mountains.
The circumstances that surround it are so bizarre and
strange that to this day they escape explanation. It could
be dismissed as a hoax, but real documents, photo, archives,
autopsy and other official documents prove that the story of
Dyatlov Pass Incident is quite real.
Dyatlov Pass Incident and Kholat Syakhl
Mount Kholat Syakhl (Dyatlov Pass is located on the side of the
mountain) gets its name from the local language of the Mansi tribe
of the Siberian Natives. Literally, it means the Mountain of the
Dead so it gained negative notoriety long before the Dyatlov Pass
Incident. According to the legend, nine Mansi hunters stayed here
overnight during their hunting trip. The next morning all nine were
found dead by their friends. None of them showed any signs of
violent death. Hence, the mountain and nearby Dyatlov Pass became
regarded as haunted, but it was never considered sacred. Local
native tribes avoided the peak and never ventured here. Mansi as
well as most other tribes were never actually conquered by the
European settlers. Instead they co- existed for centuries with
little contact on vast stretches of land. Igor Dyatlov was
particularly fascinated by these people and even made up his own
Mansi- Russian dictionary that he took on his last trip.
It
could be regarded as a cute local legend. However increased active
exploration of the region in the second half of the twentieth
century supported the grim name of the mountain. To this day people
are dying here. The cause of death often escapes rational
explanation. Mysterious number nine seems to play a weird role in
the demise of many tourists, geologists and all those who dared to
visit this place.

The story of Dyatlov Pass Incident starts on January 1959 in Sverdlovsk (it is currently known as Yekaterinburg) in Sverdlovsk Oblast (still known as Sverdlovsk Oblast) of Russia. Several students from Ural Polytechnic Institute (Уральский Политехнический Институт, УПИ) currently known as Ural State Technical Institute intended to climb Mount Otorten (Отортен) in the Ural Mountains (a geographic border between Europe and Asia). Several Russian journalists claimed that in Mansi language, the name Otorten can be translated as "Don't go there". However this is a myth. Name Otorten comes from a Mansi word Wot- tar- tan Syakhl and it means "goose mountain" as it was believed that after a great floor only one goose survived on top of the mountain. Mansi didn't regard this peak as haunted, but open slopes of its peak made ascension quite difficult and unpleasant. At the time of the Dyatlov Pass Incident, this path was classified as Category III route and regarded as the hardest of its class.
It should be noted here that neither Otorten, nor Kholat
Syakhl were held as religiously significant. They were
forbidden as they were dangerous to people, not sacred.
Sacred lands were visited by the Mansi people, forbidden
lands were avoided. Several false theories have emerged
about religious significant of this place to the native
Siberians, but these are mostly Russian yellow press trying
to make a buck. They have no credibility. In fact most of
false facts and legends were invented in the 90's by the
journalists from Russia, so this is no exception.
The whole ski track was about 350 km in length and was
carried out to commemorate 21st Congress of the Communist
Party of the Soviet Union. It was a common practice to
dedicate trips in honor of the party, cause most of gear was
provided by the University and they used any opportunity to
boast achievements of the Communist party. However, none of
the members of the Dyatlov group were actually members of
the Communist party.
The group headed by Igor
Dyatlov initially consisted of 10 people. However one of
them, Yuriy Yudin, got sick so he was forced to cancel his
trip prematurely at Second Severniy (Northern) village.
Yuriy returned home. Thus only nine people started the
ascent to the mountain Kholat Syakhl through a nameless pass
that later will become known as a Dyatlov Pass. No one saw
them alive after this.
Toward the end of the same
February, the group failed to communicate. Officials were
initially hesitant to start a search and rescue operation.
They even lied that there was a contact with a Dyatlov group
and they were simply delayed by the natural elements. A
rescue party made up of local authorities, student
volunteers and Mansi guides repeated the path taken by the
group and found the last base camp of the tourists on
February 26th. The next day, on February 27th they also
discovered 5 out of 9 bodies. Cameras were found at the site
of the tents that they abandoned. Pictures clearly show high
morale, relaxed atmosphere in a group and good preparedness
for the harsh winter of the region.
Dyatlov Group Diary - You can see more pictures from the
last trip to Dyatlov Pass and step by step walkthrough of the
journey to the Dyatlov pass incident.
Original Dyatlov group
diary of the Dyatlov group was discovered in the tent that was left
in Dyatlov Pass. We kept it as it was in the original form. You can
make a psychological portrait of the people who wrote it. It is
short and some of its sentences apparently made short on purpose to
keep to the point. We didn't add anything. The sentences and events
behind them apparently meant more for the people who were describing
them. They did not see much point in writing out the whole
description of an event. There was not enough time to do it in the
settings of harsh Siberian winter. Just a few words to remember.
Dyatlov Group Diary is not the only one that was found in the
tent. There is another short diary that was also discovered.
Official criminal investigation gave an ownership to Zina
Kolmogorova. However, her friends claimed that the hand- writing and
the style of the diary do not match that of Zina. Government
officials did not find this fact to the be worthy of note and simply
claimed it was hers. Whatever might be the case you are welcome to
take a look and make up your own mind about its ownership. After all
Dyatlov group diary was written by several members and their writing
style can be compared.
The third alleged diary on the
Dyatlov Group belonged to Kolevatov. Several people including Yury
Yudin (only surviving member of the Dyatlov Group) claimed that he
took his diary with him on his last hiking trip on the Dyatlov Pass.
Yet it was never discovered or at least its whereabouts are unknown.
Kolevatov diary disappeared from the slopes of the Dyatlov Pass or
was later removed from the police station.
Frames 31 and 32 from the Krivonischenko camera
These are the last proven pictures of the Dyatlov group
made on February 1st, 1959 as they crossed Dyatlov Pass
and began ascent of Kholat Syakhl mountain. Records show
that the sun set behind the horizon at 5:02 pm on this
date. Pictures were made just before the night descended
on the mountain. Judging by photos they are well equipped
and well protected. At least by the standards of that
time.
Low visibility due to wind and snow is an
important aspect since this could significantly impact the
movement of the group during the Dyatlov Pass Incident.
Hypothermia and confusion can set it much quicker in these
conditions. Disorientation on unfamiliar terrain can
happen very quickly and might result in a death of an
unlucky victim. Nevertheless, Igor Dyatlov and his group
set up a tent on a barren slope of the Kholat Syakhl
mountain. Some members of search party testified that
there was no firewood present in the Dyatlov Group tent.
Although other witnesses claim to see a wooden log
abandoned in the tent. Whatever might be the case the
tourists chose to sleep in the cold conditions. Later
finding showed that they started their dinner when
something happened. This "something" still has people
puzzled to this day.
Last frames of the unknown camera shows Dyatlov Group setting up a base for the tent
"In one of the cameras kept a photo frame (made by a
tourist), which depicts the moment of snow excavation
for the installation of the tent. Given that this shot
was taken with an exposure of 1/25 sec. with the
diaphragm 5.6 at 65 units of GOST sensitivity of the
film, as well as taking into account the density of the
frame, it can be assumed that the installation of the
tent started about 5 pm 02.01.1959 year. A similar
picture was taken, by another device.
After this time, no recording, and no photograph has not
been detected. "
- Decision to dismiss criminal case. Official Criminal
Investigation
Frame 33 from the Krivonischenko camera and unknown shot
This picture puzzles many people who are interested in the Dyatlov Pass Incident. One of these pictures (named frame 33) was labeled in the official investigation as belonging to Krivonischenko. Another frame has no labeling so we don't know who it belongs to. Search party discovered several cameras around the site of the Dyatlov Pass Incident. However, only Krivonischenko camera had its lens open and ready to shoot. So it logical to assume that both pictures were made by Krivonischenko.
Many people suggested that these photos were simply damaged by the elements. But it is also possible that Krivonischenko and several members of the team, those heads are visible on the right photo actually tried to make a sense of some strange event that was unfolding before them. Apparently the quality of their camera did not allow a good image. Faint borders and unclear focus makes it hard to determine what was really pictured. Some see a man with his hands raised and something flashing or burning in the background. While others see the entrance of the tent from the inside. The picture on the right seem to portray a glowing object with the heads of tourists below. Many explanations have surfaced. There is no agreement on its nature, though. Several reports of the glowing orbs were made at the time of the Dyatlov Incident. These are addressed in- depth in the Newspapers and Theories section
An interesting detail was found on the body of Zolotarev. He left the tent dressed lightly, but he had a camera on him. It was damaged by the stream, but the question remains. Who or what did he try to capture on the barren slope?
The strange event that forced Dyatlov group to abandon
the tent is still unknown and it is largely disputed.
However, it is plausible that at the time Nikolai
Nicolai Thibeaux-Brignolle and Alexander "Semen"
Zolotarev stood outside of the tent as they were better
dressed than the rest of the group. Tourists of the
Dyatlov Pass group had little or no footwear even though
they always carried two sets of shoes for hiking
("valenki"- traditional Russian winter foot- wear) and
another set of boots for sleeping inside the tent.
A search party discovered the Dyatlov Group tent on
February 26th. It was cut from the inside with a knife.
Tourist itself was filled with food, warm clothes and
anything that could have saved lives of young men and
women.
Map is based on notes left by Maslenikov
who participated in a search of the Dyatlov Pass
Incident
Dyatlov Group tourists descended straight down the mountain slope and reached a large cedar at
the boundary where the forest ended. Two men (Doroshenko and
Krionischenko) stayed under a cedar and even started a
fire. They stayed behind and tried to keep the
fire going. The rest of the group descended even further and
constructed a den in the branch of the Lozva river. Once Dyatlov
Group returned to the cedar they discovered
that the two men dead of possible hypothermia. Bodies of both men were
covered in strange bruises and injuries. Survivors took off clothes
of their dead friends, including those that were stained with
radiation. They used knives to cut these clothes since rigor mortis
probably set it. We can't blame them as they tried to
save themselves by all means possible. However presence
of the semi naked bodies under the cedar gave rise to a
popular legend about "paradoxical undressing".
Unfortunately even Wikipedia mentions it as a possible
explanation for the Dyatlov Pass Incident.
Three
tourists of the Dyatlov Group, Dyatlov, Slobodin and
Kolmogorova, decided to return to the tent. Whatever
caused them to flee their base camp on a first place
either passed or the tourists assumed that it did. They
tried to walk up the mountain, but fell from exhaustion
and coldness. All five bodies including the two under
the cedar and the three on the slopes were discovered on
February 27th. Since all the corpses were barely dressed
and found in the line, first searchers assumed that they
were blown out of the tent.
Additionally, the
search party found two flashlights on a site of a
Dyatlov Pass Incident. Once Chinese flashlight was found
on top the ripped tent. It was covered by 5- 10 cm of
snow. Boris Slobtsov turned it on and it was in a
working condition. Another flashlight was discovered by
the third ridge around 400 meters down a slope.
Batteries were drained so there was no point of carrying
it. This flashlight was probably dropped by one of the
members of the Dyatlov Group on the way down the slope
of the Dyatlov Pass.
The other four members, Zolotarev, Kolevatov, Thibeaux- Brignolle and Dubinina, returned to the tent where they have met their gruesome end. Their ribs were broken, the skull of Thibeaux- Brignolle was broken, eyes were removed in some of the bodies. Additionally, Dubinina had her tongue missing. Bodies of the last four members of the Dyatlov members was discovered in late spring by Mansi hunters. Their deaths were classified as unnatural and violent.
Dyatlov Pass Incident became mysterious and puzzling right from the start. Many theories have surfaced as soon as the bodies were found. Natural factors were blamed, special forces, Mansi attack. Some even considered Yeti, UFO or other supernatural attacks. But to this day we don't have a single concrete answer that explained all the evidences and founding discovered on a Dyatlov Pass. Nameless pass to the mountain was named Dyatlov Pass and the whole tragedy became known as Dyatlov Pass Incident (or Dyatlov Pass Accident depending on a view). To this day it remains one of the most famous unsolved mysteries. We have included photos, diary, the official autopsy of the Russian tourists as well as major theories for the explanation of this event. You can add your own theory of the Dyatlov Pass Incident if you'd like.
Today you can get to Dyatlov Pass by foot, helicopter and even by car.
Dyatlov Pass Incident was never classified, but
numerous testimonies (particularly the Mansi people) was
simply tossed out and ignored. Description of the missing
tongue is intentionally vague. In fact the autopsy of the
last four victims (found in the den) that show violent
deaths were surprisingly short. It is hard to say whether
the prosecutor tried to make his life easier or whether he
had orders from Moscow. We will never know why, but there
was tampering with the evidence.
We should also mention
that the confusion comes from inability to distinguish
between the MVD (the Police) investigation and a KGB
investigation. We already talked about MVD investigation,
but KGB investigation that probably was initiated was
certainly classified. We say "probably initiated" for two
reasons. Dyatlov Pass Incident involved radiation and it
was a state affair by default. Secondly after the
investigation clearly showed the presence of radioactivity
that was well beyond natural amount Dyatlov Pass Incident
investigation suddenly stops. Lets look at the dates.
Radioactivity is established on May 27th, on May 28th the
investigation is over and on 29th Levashov (who was in
charge of the radioactivity report) is asked repeatedly on
the nature of his findings and confirms that this level of
radiation couldn't possibly be due to a natural exposure.
The timing between closure of the case and a discovery (or
confirmation) that radiation was present is curious to say
the least. You would think that any prosecutor would love
to solve such a mystery. It would honor the dead and it
would preserve lives from subsequent radiation exposure if
it is still found on the Dyatlov Pass. But Ivanov doesn't.
He simply closes the case of the Dyatlov Pass Incident.
Yury Yudin, an original member of the group in his last
interview in 2012 claimed that KGB agents did question
him. As we said earlier presence of radiation had to
trigger the involvement of the KGB. But major question
remain unanswered: did the KGB merely respond to the
Dyatlov Pass Incident or did they try to hide their guilt
in the death of the students?
Tent of the Dyatlov Group
was ripped from the inside. Initially, this fact was
overlooked, but a woman who worked for the police
department laundry services clearly identified that the
damage came from the inside. Her explanation was simple
and ingenious. She looked on the inside of the Dyatlov
Group tent and saw several cuts made to the inside
surface. Not all of these cuts made it all the way through
the canvas, but it gave an idea the location of a person
or persons who did it.
Further expertise proved her hypothesis to be correct (scans from the criminal investigation analysis of the tents is available here Additional Documentation). However, no one was able to identify who and why made these cuts. Lack of eye witnesses to the Dyatlov Pass Incident left many people to speculate that where was someone else on the slopes of the Dyatlov Pass. Additionally, search and rescue party admitted that they increased existing holes by ripping the pre- existing cuts. We can't even tell for sure if the Dyatlov Group members used this alternative way to leave the tent. Some theories about the Dyatlov Pass Incident claim that these cuts were made by whoever forced the group out of the tent and used these holes to keep an eye on the slope of Kholat Syakhl mountain.
Nine tourists left the tent with little clothes while outside temperature dipped to -30°C (-22°F). Most of them lacked proper footwear. Warm clothes, boots were left inside the abandoned tent. Survivors go to extreme lengths to preserve themselves in their harsh conditions. They even cut the clothes of their dead friends to protect themselves. They even dig a den that does not save them. Thus the theory of "paradox undressing" has no support in the available facts.
One of the ski poles show signs of damage made by the knife. Many theories and explanations have surfaced, but no one could give a proper answer on why would tourists damage such an important part of their equipment.
During the criminal investigation into the Dyatlov Pass Incident, someone came up with an idea to test the clothes of the dead skiers for radiation. Clothes of George (Yuri) Krivonischenko were positive for the presence of the beta radiation. However, bodies themselves did not show a trace of radiation. The question remains. Who came up with this strange procedure and why was it even carried out in a first place?
The reaction of the officials was also surprising. The tests were carried out between May 18 and May 25 of 1959. And on May 28th just three days after the presence of radioactivity was confirmed the case was officially closed. This is more than just peculiar given the circumstances. It is possible that the investigation into the Dyatlov Pass Incident did continue but under the supervision of detectives from the KGB, not police.
Kolevatov kept a personal diary. Yuriy Yudin, the only survivor of the group, testified that it was with him on the last trip. The diary went missing.
Judging by the pictures of the Dyatlov group at least one of the cameras went missing.
Strange unidentified cloth "obmotki" or puttee was found near the bodies. This is an old version of protection for feet worn by soldiers in the Red Army. It is a long narrow band that was wrapped around shoes to protect the feet of servicemen from natural elements. They were faded out in the 1940's during World War II, but many veterans kept it after their service. According to Yury Yudin no one in the group carried them.
Missing tongue and eyes. The cause is unknown. What makes the fact more mysterious is a lack of coherent explanation or description of the damage. The autopsy doesn't mention the state or nature of the surrounding tissues.
The bodies of the dead tourists show signs of
unexplained damages including broken ribs, scrapes and
etc. It might indicative that the Dyatlov Pass Incident
was more complicated that a mere case of hypothermia
Semen Zolotarev introduces himself as "Alexander" to the
group. In fact, even a common memorial to the group lists
his name incorrectly.
Semen Zolotarev and George (Yuri)
Krivonischenko are buried separately from the rest of the
group on a cemetery that is officially closed for several
years.
Money, food, valuables like watches, alcohol,
and blankets remained in place. Nothing valuable was
taken.
Zolotarev left the tent exposed to the natural
elements, yet he had the time to take his camera along.
The water have damaged the film and we can't use it, but
still the question remains. All the actions of the Dyatlov
Group appear logical. They build a fire, they dig a den to
keep themselves warm, they try to make it back to the tent
once they feel it is safe to do so. But why would you take
the camera with you?
Now that we stated facts that are true let's dispel numerous "facts" that circulating around the internet concerning the Dyatlov Pass Incident. These statements were probably taken from the Russian articles that were published in the past 30 years. In the English speaking area of the internet they keep reposted in various versions. So without much edo, lets start.
No. Dyatlov never said that Yeti actually exists. There was some reported activity in the area of the Dyatlov Pass Incident of a creature that we Westerners know as Yeti, but these were rumors and only Mansi hunters reported attacks on their reindeer, not humans. For more information on the subject you can check out Theories section or Dyatlov Pass Newspaper.
Dyatlov Group members did not show premature aging.
There was no expression of fear or horror on their
faces.
Skin color was different, but the tone was
consistent with normal decomposition.
Last four
victims were buried in zinc coffins. It is a cheap
available material for coffins. There is nothing amazing
or peculiar about this fact. In fact Russian expressions
like "zinc suit" or "zinc dress" is an euphemism for
death.
Dyatlov Group had no rifle on them. The
confusion comes from an old photo of one of the Dyatlov
group members. He went on another journey where one of
men held a rifle. This picture is from a different trip
and a different group.
Ultrasound theory is cute, but
the retreat from a tent wasn't so chaotic. As far as we
know no one was running as members stayed together.
Group was organized. A flashlight was taken (presumably)
by the group and abandoned 400 meters since its
batteries were dead. These are actions of organized
people who were thinking straight. Whatever caused them
to flee was destructive enough to loose their minds.
Metal pieces from planes are from later crashed in the
area of the Dyatlov Pass Incident. They were not present
at the time of the Dyatlov Pass Incident. At least
search party didn't record any findings.
This section
is destined to get longer as we will come up with new
myths and legends that surround the Dyatlov Pass
Incident.
The Mystery of Dyatlov Pass Тайна перевала Дятлова: 2000, TAU (Ural Television Agency) (ТАУ - Телевизионное Агентство Урала, 2000г.)
