The Dyatlov Pass Incident

Record summary

Nine Soviet hikers died during a winter expedition in the northern Urals, producing a durable mystery narrative involving damaged tents, unusual clothing choices and incomplete early records. The case is relevant to missing-time and altered-state comparisons because cold exposure, disorientation, panic, terrain, wind and group behavior can generate apparently inexplicable sequences. Later forensic and modeling studies have proposed slab avalanche or snow-slab mechanisms, while other hypotheses remain popular. The original investigative file, translations and later reinterpretations should be compared carefully.
