[ Much snow would have accumulated during the many weeks before the bodies were found. Any tracks would have been covered over. ]
I may not have explained myself well. The point I'm trying to make is how the trail came to be discovered, this I feel is important as it can help us to narrow down the variables .
It is not a trail of footsteps or how the snow lies that indicates the trail found by the Mansi , it is the cut young trees , ripped clothing and then the broken foliage that have come off during the transportation of the cut trees that gives the the trail down and directly to the den.
It is the layers of material in that snow level, that at least imply ,that this was the one of the last and only activities at that location and what was found around the ceder.
When an archaeologist digs down through layers he will find many things , a layer of volcano dust for example, the bones of our ancestors and then dinosaurs for example but the layers give us a time line.
The areas around the ceder, ravine and towards the tent all have snow , I suggest that it would be nearly impossible for anyone or anything to be able not to leave a visible trail , especially in the forest.
The experienced Mansi , especially from their hunting skills would have been able to locate other trails but it would seem that the didn't. When the thaw was good enough all that was left at that level in the snow was what was found. It implies that there were no others moving things or digging trenches or making fires.
Archaeology is one of my hobbies. Snow is an important part of the mystery. But we can't excavate snow the way we can excavate the ground that the snow covers. The Dyatlov group where found some time after the incident, so all sorts of things could have been going on weather-wise in that area. We don't know.
Sarapuk, could you please edit your reply so it shows who said what.
If archaeology is one of your hobbies you would understand what I am putting forward. I will try to explain to you again. The layer in the snow of broken bits of tree and ripped clothes showed exactly where activity took place at the den and the Cedar. There are no reports of activity in the snow elsewhere after the thaw.
The layers of snow are like an accelerated form of what happens in time to the earth layers. Hope that helps.
