The Dyatlov Pass incident, where nine experienced Russian hikers died in 1959, remains a mystery. While a snow avalanche was initially considered, inconsistencies with the evidence led to alternative theories. This study proposes a new mechanism: a slab avalanche triggered by wind-blown snow accumulation on an irregular slope, exacerbated by a tent-installation cut and strong katabatic winds. The model explains the delayed avalanche, unusual injuries, and lack of typical avalanche signs.
