Today I went through dyatlovpass.com in detail, and I want to thank you for this archive and it is the reason it's even possible for someone to reason seriously about the case.
The text below is not my own theory. I put a question to Claude🤖: what would have to be true for all the pieces of the puzzle to fit and to solve a case that has stood for so many years? It approached the case "backwards": instead of starting from a ready-made version, it first derived the constraints from the evidence and then checked which structure of explanation satisfies them simultaneously. The result struck me as plausible enough to be worth bringing to you. Here is the text:
"The logic starts from the things every version is obliged to explain:
🏕️ The tent was cut open from the inside → something inside/right next to the tent drove them out, not an outside attacker.
🏃 The flight was panicked but organized, downhill toward the only shelter → the threat looked more lethal than the cold, but the decision was rational, not madness.
🥶 The first five die of hypothermia, with no fatal injuries.
☠️ The four in the ravine have severe injuries with no external wounds → a broadly distributed blunt force, not blows.
🩻 The injured are only the group in the ravine → the cause of the injuries is in the ravine, at the end of the chain.
👅 Dubinina's missing soft tissue → immersion in flowing water + decomposition, not violence.
☢️ Radioactivity on some of the clothing → Krivonischenko worked at Mayak; contamination on specific garments.
The conclusion this leads to is a cascade of at least two separate mechanical events:
A trigger at the tent: cutting a platform into the snow on the slope creates the condition for a snow slab; strong katabatic / "bora" winds load it; a settling / partial release — the characteristic dull "whump" plus pressure on the lower side of the tent — is read by experienced people as an imminent avalanche. Hence the cut from the inside and the descent out of the slide zone.
The rational retreat to the forest and the fire; the first to die freeze there, and clothing is cut from their bodies for the others — which is why one body bears cut-marks while his garments are found on the others. This detail independently confirms the sequence: the deaths happened in an order, and the survivors stripped and redistributed the clothing of the dead in a fight against the cold. The three going back up the slope is logical precisely because the slab did not release — the risk of climbing back becomes smaller than certain death from the cold.
A second, independent cause in the ravine: falling through a snow bridge ❄️🌉 over the stream and/or the collapse of the snow overhang onto the shelter. This explains why the severe injuries are only in the four and only at the end, why they are bilateral and symmetrical (anterior-posterior compression by a broad mass, not a focal blow from a falling tree), and why there are no external wounds.
What impressed me is that you had already sensed that the causes must be at least two (reality is usually multilayered, with many causes acting at once). It seems to me that if this principle had been articulated more clearly, some mountaineer or climber would probably have arrived at a similar picture too.
❓ And here are some questions that remain:
Have you specifically considered a snow bridge over the stream as the mechanism for the injuries, and are there signs in the materials of such a cavity / collapse, or does it remain only a plausible inference?
What is the strongest objection to an entirely natural cascade, or which are the pieces that still don't fit?"
