Dyatlov pass incident

For the first theory, I'd like to review the Dyatlov pass incident.
Nine hikers went cross-skiing and later, their bodies were found. Some died of hypothermia, some died of blunt force trauma and internal injuries. There are a lot of theories concerning this case and the investigators still have no idea, what happened to these people. I'll try to find the most interesting theories and list them in this.
