Minute‑by‑Minute Reconstruction of the Ravine Four (Plausible Sequence Based on Avalanche Medicine & Autopsy Evidence)
Below is a medically realistic timeline of what likely happened to the ravine four after a snow‑den or cornice collapse.
It’s not speculation about “mystery forces” — it’s simply what the injuries and physiology point to.
---
0–1 minutes: The collapse
- A section of the snow roof or cornice gives way.
- Heavy blocks of snow/ice fall into the den or ravine.
- One block or edge strikes Thibeaux‑Brignolle’s head → single massive skull fracture.
- Others land on the upper bodies of Dubinina, Zolotaryov, and Kolevatov → initial inward‑bending rib fractures.
- They are not fully buried; air pockets remain.
---
1–5 minutes: Pinned but alive
- They are conscious, shocked, and trying to orient themselves.
- Breathing is already restricted because the chest wall is compressed.
- The heart is still pumping strongly → bleeding begins immediately around the fractures.
- No external abrasions because the load is snow, not a hard impact surface.
---
5–15 minutes: Hypoxia and hypothermia accelerate
- Snow settles and compacts, increasing chest pressure.
- Breathing becomes shallow and laboured.
- Oxygen levels fall → hypoxia.
- They were already cold; now immobilised in snow, heat loss accelerates.
- Core temperature drops into the low 30s°C.
- Clotting begins to fail → cold‑induced coagulopathy starts.
---
15–30 minutes: The “lethal triad” sets in
- Breathing is severely restricted; chest expansion is minimal.
- Consciousness fades in and out.
- Physiology deteriorates into the trauma “lethal triad”:
- hypothermia
- acidosis (from low oxygen)
- coagulopathy (clotting failure)
- Internal bleeding becomes massive because the body can no longer clot.
- This is when the autopsy‑level haemorrhage is being created.
---
30–60 minutes: Irreversible decline
- Breathing becomes agonal or stops entirely.
- They are unconscious or unresponsive.
- The heart continues beating weakly for part of this window →
enough to keep pumping blood into damaged tissues, explaining the extensive haemorrhage.
- Death occurs from a combination of:
- asphyxia (chest cannot expand)
- hypothermia
- internal bleeding
This is not instant suffocation — it is a slow, multi‑factor decline.
---
1–3 hours after death: Post‑mortem settling
- Bodies remain pinned in the same compressed positions.
- Snow continues to settle and compact around them.
- Over the following weeks, more snow falls, compresses, and gradually lowers them into the stream channel.
---
February → May: Freeze–thaw and meltwater
- Meltwater eventually begins to flow around and under the bodies.
- Soft tissue (eyes, mouth, etc.) is lost post‑mortem due to water action and small scavengers.
- By the time searchers arrive in May, the ravine has opened up and the bodies appear to be “in the stream bed” —
but this is the result of months of settling and melt, not their original position on 1 February.

Why this timeline fits the evidence
- Inward rib fractures → slow compression, not blast or fall.
- Massive internal bleeding → they were alive long enough to bleed.
- No external trauma → snow load, not impact or shrapnel.
- Skull fracture → single blunt impact from a falling block, not a pressure wave.
- Final position in the stream bed → natural settling + meltwater, not an impact onto bare rock.
- Cold‑induced coagulopathy → explains why the injuries look “severe” without requiring extreme force.
