In 1959 a group of Russian hikers decided to head out on an expedition of a mountainous region of the western Soviet Union, the group itself consisted of 9 experienced men and women, all of whom were very familiar with the Siberian wilderness yet this adventure would prove to be their last.
Despite a criminal investigation, photographs and journal entries the case to this day remains unsolved after more than half a century. This is the case of Dyatlov Pass.
This is a film by the YouTube channel LEMMiNO, they have also added a correction to one of the points mentioned in the film:
After reexamining some of the medical reports, it appears none of the hikers were intoxicated. The mistake was due to a mistranslation from Russian to English.
