About Dyatlov Pass Incident Project

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 leave your comment below.


Dyatlov Group Incident Background

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.

Dyatlov Group

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.

Diary of the Dyatlov Group discovered on Dyatlov Pass

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. "

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?


Discovery of the Victims of the Dyatlov Pass Incident

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.

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.
