Is it possible to narrow down what happened to the Dyatlov group by considering the absence of injuries which you'd anticipate would be present in a given theory?
If they were attacked there were no defence injuries. A surprise attack, a blow to the head, might render one or two unconscious in the dark, but the rest? Only Yuri K reliably had any knuckle injury, to one hand, and Zina a gash to her hand.
If they fell while conscious they should have injuries to their hands/wrists, and broken collar bones from trying to break their fall, the weakest part where stress travels up the arms. (This, to me, has always been one of the most puzzling facts about the mystery.)
If they were caught in an avalanche, and less so a slab-slip, some of them should have broken limbs or dislocations. These are the most common injuries in crush events caused by a mass of travelling snow.
If they were exposed to explosion then unless on the periphery of this event and concussed by it and thrown to the sides they should have external traumatic injuries including perforated ear drums and at least one or two should have bled to death.
If run over by a snowmobile or herd of deer there should have been some internal rupture to vital organs from the pressure points found at autopsy. Ditto had a tree fallen on them (which would be remarkable too if no limbs were broken).
If hit by ball lightning there should be rather more burns than Yuri K's leg.
If attacked by a yeti some of them should have reacted like Teddy probably did to a bear in the forest.
