WARNING: Images of the group's corpses are included in this blog post. Images may be disturbing to some viewers.


The group consisted of students and alumni from the Ural Polytechnic Institute. The group was led by 23 year old Igor Dyatlov (Игорь Алексеевич Дятлов). Other members of the group were 38 year old Semyon Zolotaryov (Семён (Александр) Алексеевич Золотарёв), 24 year old Alexander Kolevatov (Александр Сергеевич Колеватов), 23 year old Rustem Slobodin (Рустем Владимирович Слободин), 23 year old Nikolai Thibeaux-Brignolles (Николай Владимирович Тибо-Бриньоль), 23 year old Yuri Krivonischenko (Георгий (Юрий) Алексеевич Кривонищенко), 22 year old Zinaida Kolmogorova (Зинаида Алексеевна Колмогорова), 21 year old Yuri Doroshenko (Юрий Николаевич Дорошенко), 21 year old Yuri Yudin (Юрий Ефимович Юдин), and 20 year old Lyudamila Dubinina (Людмила Александровна Дубинина). They were all very experienced hikers, with all but Semyon Zolotaryov participating in the hike to achieve Grade 3 certification. With this certification the members would be able to teach hiking as Masters of the Sport. Zolotaryov already had his Grade 3 certification and was the only newcomer to the group. The plan for the group was to complete a hike through the Ural mountains to Otortan (Отортен). The entire trip would total to 300 kilometers, the requirement for Grade 3 certification.

Official statement for closing the case given by Junior Counselor of Justice and Criminal Prosecutor of Sverdlovsk region, Lev Ivanov:

The deaths of the expedition members were due to a series of mistakes by Dyatlov. On 1 February he began the ascent to the summit at 3 PM, even though he knew about the difficulty of the terrain. Furthermore – and this was Dyatlov’s next mistake – he chose a line 500 m to the left of the planned pass that lies between Peak 1079 and Peak 880. So the group found themselves on the eastern slope of Peak 1079. They used what was left of the daylight to ascend to the summit in strong winds (which are typical for this area) and low temperatures of minus 25 degrees centigrade. Dyatlov found himself in bad conditions for the night, so he decided to pitch his tent on the slope of 1079 so as to start in the morning without adding the distance from the forest (~1 km) to the remaining trek of about 10 km to the summit.

Considering the absence of external injuries to the bodies or signs of a fight, the presence of all the valuables of the group, and also taking into account the conclusion of the medical examinations for the causes of the deaths of the hikers, it is concluded that the cause of their demise was an overwhelming force, which the hikers were not able to overcome.

Theories

There are multiple theories associated with the Dyatlov Group. These theories range from the more probable, a romantic rivalry within the group, to the outlandish, such as an alien invasion. Other common theories involve Soviet military weapon testing, an attack from the native mansi tribe, and even a Yeti attack.

For sake of this podcast, we focused on two theories: The Frozen Theory and the Russian-Swedish Theory. The Frozen Theory was named after the animation programs used to test the theory were the same programs used for creating Disney's Frozen. Below is a diagram associated with the "slab avalanche" theory that Gaume and Puzrin were putting out.

My personal issues with this theory as well as the positives and negatives associated with this theory can be heard in our podcast episode.


The next theory is the Swedish-Russian Theory put out by Richard Holmgren and Andreas Liljegren. Below are infographics made by Kalee that illustrate the theory.



To hear more discussion on the theory please listen to our episode or visit Holmgren's blog.


The major reason for this discussion, other than to bring attention to two credible theories, is to remember the group from Dyatlov Pass.

  • Igor Dyatlov was the group's leader. He was described as highly intelligent and meticulous. He was very well-trusted throughout all of Ural Polytech.

  • Yuri Doroshenko was 180 cm tall. He was considered impulsive and brave.

  • Yuri Krivonishchenko was considered a joker, musician, and master storyteller. He studied construction and hydraulics at Ural Polytech.

  • Zinaida "Zina" Kolmogorova was described as lively and bright. She was outgoing and attractive. Many of the male hikers admitted in their journals to having a crush on her.

  • Rusem Slobodin was also a musician, always carrying a mandolin with him. He received his degree from Ural Polytech in mechanical engineering.

  • Alexander Kolevatov was a nuclear physics student at Ural Polytech. He had an internship where he worked in labs on campus. Alexander was known for his imposing physique but was described as methodical and private. He enjoyed smoking a pipe.

  • Nikolai Thibeaux-Brignolles was considered the most humorous of the group and helped keep spirits high. He was serious and well-read.

  • Lyudmila Dubinina was the youngest of the group. She was a fervent communist and very outspoken. She was described as being highly principled and serious. To counteract her serious nature, she was also described as extremely witty and helped with keeping the group's moral high.

  • Semyon Zolotaryov was the oldest member of the group. He fought in World War II. Already having his Grade 3 cert, the group trusted his expertise and went to him often for advise.
