Johan Gaume for Dyatlovpass.com. In our new article in Communications Earth & Environment, we report five main findings relevant to the Dyatlov Pass incident:
Dyatlovpass.com follow-up questions. Invisible avalanche? How do you answer these questions then:
Gaume: The avalanche is visible, audible and can break your ribs if it hits you when you are lying down. The release area of a small slab avalanche is quickly covered by the new snow and becomes difficult to detect. This is what Oleg and Dmitriy observed two months ago.

b. Picture taken by Dmitriy Borisov on the 29th of March 2021 from the Dyatlov Pass. The zone highlighted in red is located ~3 km away from the tent.
c. Picture extracted from a video taken by Matteo Born (RSI movie director), the day later, i.e., 30th March 2021.
d. Picture of a crown tensile fracture on the left side of this slope taken by Dmitriy Borisov on 29th January 2022.

The Swiss "avalanche" team Alexander Puzrin and Johan Gaume have a second paper in Nature.com Post-publication careers: follow-up expeditions reveal avalanches at Dyatlov Pass publishing data from expeditions to the Dyatlov Pass documenting avalanches on the other side of the pass, not on the side where the tent was, and 3D model showing plenitude of red spots where the terrain is close to 30° and they are high fiving since they used in their calculations 28° if I am correct, fact check me on this. Basically the scientific paper proves that a freak avalanche can happen on the Dyatlov Pass. There still need to be certain parameters present: combination of irregular topography, a cut made in the slope to install the tent and the subsequent deposition of snow induced by strong katabatic winds.
We are now not arguing if an avalanche can happen, Puzrin and Gaume convinced us that it could with their first publication Mechanisms of slab avalanche release and impact in the Dyatlov Pass incident in 1959 and this one only confirms it.
But the avalanche theory doesn't answer any of the questions that arise from the case files. It was the first theory that the investigation in 1959 looked into, and it was discarded not because there couldn't have been an avalanche, but because there was none.
The evidence in the case files shows no avalanche, and this new publication can't change that:
What we should take from this paper is that if there was an avalanche in 1959, it should have been readily apparent to the first responders. Now you see what a slab avalanche looks like and know that there wasn't one on the photos taken in 1959.

I've attached the 3 most pertinent photos from the search, colourised and restored.
While some claim 3 week's worth of windblown snow would fill the void left by a slab slip breaking off, I'm not convinced it would do so completely or create such a firm surface that men could stand on it and not realize what had happened there.
And the only visible evidence of any potential avalanche was immediately below the tent site, where some 2 tones of snow (possible to calculate the volumetric weight online for snow crust) had been thrown when a tent trench was dug out, the large clumps which would survive the wind. (And some on the tent, along with a torch.)
