Happy New Year Starman: I agree. The condition of many of the hikers had to be at the lethal level by the time they got to the cedar due to not wearing enough clothes. If they fell on the rocks according to Borzenkov, with their ribs in a straight line, how could they have even made it to the den or ravine? Borzenkov thinks Kolevatov carried or pulled the other 3 hikers to the den after they fell off a ledge on the way to the cedar. How could he do this with all of his ribs broken?
Every theory here still demands an answer as to why they left the tent for certain death. Even if they were all healthy and no broken bones, they would obviously freeze to death. Then you add the climbing up the cedar, perhaps in a delusional frenzy thinking they may be safer there? It makes no sense.
The only thing that makes sense is that the first five died near the cedar due to trauma, elements? The other 4 managed to get down to the ravine which they crossed and were not badly injured, to build the den and then ended up dying in the ravine?
