Dyatlov Pass Incident
A witness reportedly came forward in March 2026 with details about a potential military incident, including the burning of evidence, suggesting a failed Soviet rocket launch as a possible cause for the 1959 Dyatlov Pass incident in the Ural Mountains. As of April 21, 2026, new evidence and testimony suggest three Dyatlov Pass victims did not die from cold but from severe injuries, with expeditions planned for May 2026 to search for rocket fuel components and nitric acid traces. This comes despite a 2020 federal investigation concluding a slab avalanche was the most likely cause, a theory also supported by Swiss researchers in March 2026. A former detective, Vladimir Kolyagin, suggested in January 2026 that the Dyatlov group might have been testing a shortwave radio invented by Dyatlov, while historical notes from the 1960s reveal a regional committee allegedly told parents "The Guilty Have Been Punished."

Swiss researchers have proposed a new theory for the Dyatlov Pass incident, suggesting a slab avalanche caused the deaths of nine hikers in 1959. Using computer modeling, they argue this type of avalanche could explain the hikers' injuries and the tent being cut from the inside, leading to their panicked flight into the cold.
