I have so many problems with every theory I have read about, even the simplest ones.
Dear sparrow !
Strange as it may seem, these questions already have answers if you just include the logic and knowledge of a particular area, as well as the conditions that are there all the time.
We will disassemble everything separately.
If the rav4 were walking along slowly, which seems logical, then when they came to the ravine, would not they have fallen over and slid a ways?
It is necessary to consider everything here in more detail, but you asked the question too abstractly. Please formulate the question in more specific way.
From what is already clear, I can say this:
1. They were walking slowly and came much later than the two Yura were at the cedar because they had carry Nikolai Tibo from the place where he was wounded.
2. On a slope they have fallen because they have not seen an edge of snowy top of a ravine against a white bottom. The white background is not visible in the darkness at all. But they saw the reflections of the cedar fire from above and went there because the fire meant warmth (as they thought it burned well) and they had already frozen in the cold.
If that were the case then why are there no scratches or any bruises except for the one on Lyuda?
First you have to understand why they have to be?
Further it is necessary to take into account, that in the big cold and fast (relatively) death they may not form. In addition, it should be taken into account that they were wearing clothes that to some extent protect it. And the most important thing is that on partially decomposed bodies it is either impossible to detect or Dr. Revived did not describe it, because it is very difficult to distinguish it from postmortem changes associated with additional efforts during transportation.
There is a very "slippery" question, which cannot be answered with a completely accurate answer. There are it is so many options.
If the snow cushioned their fall then how did they get broken bones?
Everything works only within the limits of the possibility commit such events. Snow can soften a fall, but only within very small limits. You have to understand the relationship between the energy of a fall and the ability of snow to absorb that energy. According to Vladislav Karelin (he is one of the few people who could assess this situation well and correctly - he was well qualified for it), there was very little snow, so do not focus on the properties of snow to absorb movement. How much do you think can absorb 30 or 50 cm (0.5...0.7 ft) of snow (especially if it is not dense) if mans rolls down a slope 8m high (25 ft) and stops abruptly?
If they were in the den and it collapsed on them then why didn't at least one of them die from asphyxiation?
This is a typical misconception of those who do not know this place and conditions at all, but are trying to say something of their own. It's very fantastic. It's more fantastic than a UFO.
There's no way something's gonna collapse, especially if there's a lot of snow.
In March, there is more than an order of magnitude (~10 times) more snow there. In addition, it should be said that the snow is loose there until the intensive melting begins. It happens only in the second half of April or the very beginning of May.
In the stories of our March expedition 2019 (a week before the prosecutors arrived there) we tried to dig a cave in the snowiest place. That's what it looked like:
For reference: the full height of the measured river is 130 cm (4.3 ft). If you understand correctly, the diameter of the entrance (and in general the cave) is about 1 m (3.3 ft), so even for two people there will be tight, low and it will be difficult to get the right length along the slope.
In order to build this, we had all the necessary tools (avalanche shovel, skis, snow knives, good visibility and a complete understanding of what we are doing and why we are doing it), which they did not even have partially.
Even if the whole top part (~ 40 cm or 1.3 ft) collapses (this is very easy - the snow there is very loose even in March), nothing special will happen, this snow can be easily thrown off by hand. There will be no excesses, no one can suffocate or get hurt.
Let me remind you that there was much more snow this time than there was in March 1959. According to the available landmarks in the 1959 photos, the 2019 level was 0.5 ... 1, 2 m (1.5 ... 4 ft) more. This was measured in different places. We measured 8 points, which we were able to identify from the photo.
So nothing fell anywhere, and nobody died from suffocation because there were no such conditions.
If they died where they fell then how did Lyuda end up at a right angle and further away ( from the top edge of the ravine) than the three guys?
First, it is necessary to understand that the place where people were injured and the place where people died may be different, although it is not far from one another.
If you believe they were washed to where they were found then how could it look like Alexander was holding Simon?
Regarding the term " hollow out", I would prefer not to think in fantastic categories. It's not physically possible. In addition, the protocol states that the bodies (except for Luda) were placed with their feet in a layer of snow. So they could have shifted (bent) very slightly where the water was flowing and they didn't touch the old snow, but they couldn't have moved on if they weren't completely broken. According to my calculations on the ground this distance was about 40 m (20 ft).
If Simon was too cold to write a message (or whatever) then why is he still able to hold a pencil and notebook? And on and on the questions go.
It was just a vague memory of Vladimir Askinazi. I tried to clarify it several times in his e-mails, but he gives different answers each time and said that he remembers it very vaguely and does not want to confirm it exactly.
Additionally, you can take close look at the photo of the bodies in the stream taken before they were extracted:https://dyatlovpass.com/resources/340/gallery/Kolevatov-Zolotaryov-Thibeaux-Brignolle.jpg
these photos show no notebooks or pencils. Even if you assume that it is not visible there, try to imagine in what hand he could hold it, if the fate that Semen was behind Alexander's back (it can be considered that he carried Semen)?
As you can see, when you look at the whole picture in detail and throw away what is physically impossible to do, everything is quite simple.
