Thank you, Ziljoe and Osi, for these remarkably detailed and well-founded observations.
Ziljoe, your analysis of the wind, which made the descent from the northeast the path of least resistance—and your observation about the thin layer of snow under the dense canopy of cedars, which provided an immediate surface for making a fire—fits very well into the mechanics of survival, although I insist that it would have been better for them to have gone in the direction they knew. I maintain that they descended the slope in the northeast direction because they were forced to descend the slope in the worst condition. I know this because walking in the cold and against the wind is much worse. I maintain that those who were most exposed to the wind were the first to die, and the choice of the northeast direction was purely out of lack of options.
Your interpretation of Question 4 (that Kolevatov simply escaped the direct structural impact/weight that crushed the other three in the ravine) also offers a very clear and pragmatic explanation, without the need for external anomalies, although I might question: at what point were they hit? If Kolevatov was clinging to Zolotarev, and we know that Zolotarev died of hemorrhage, we can organize these facts and conclude that they knew some of their companions were injured.
Regarding SURI's point in Response #14:
SURI, if Dyatlov, Zina, and Slobodin fainted during the descent, how do you reconcile this with the forensic position of their bodies? The three were found oriented with their heads pointing upwards, towards the tent, with their arms positioned in a classic crawling/climbing posture. If they had died descending from the tent, their posture and orientation would reflect a downward movement or fall-absorbing mechanisms, not an upward movement. Also, there were borrowed clothes on their bodies (I remember there was a vest), but how to explain the distance between the bodies, if they possibly climbed up together? (And also the fractures in Slobodin)
The chronology seems to be focusing on a twofold survival effort: immediate fire in the cedar to gain dexterity/survival, followed by the construction of the shelter in the ravine and, finally, a desperate attempt by the healthier members to retrieve the tent equipment, although I consider that they all descended to the bottom of the slope healthy, while building the den, when the collapse occurred injuring the three. Then the 6 unharmed split up, with three remaining to support the wounded (which explains the fire under the cedar for signaling and guiding the 3 who climbed up to the tent to get supplies).
