Hypothermia - a timeline

[Arjan]

The next five images show a timeline for hypothermia within the group members who had left the tent area around 16:30 pm and who had tried to survive in the cedar/ravine area.

With 99,999 % certainty, this timeline proves:
1. None of these group members (who had tried to survive in the cedar/ravine area during their fatal night) had been able to replace the body of another group member while rigor mortis and post mortem lividity had developed in this replaced body.
2. Outsiders òr group members who had stayed in the tent during that night had repositioned the unconsciousness body, while rigor mortis and post mortem lividity had developed in this replaced body.

Remark: for group members who may/might have stayed in the tent, this timeline starts around 9:30 am the next day, of course with an extended timescale, because during daytime the temperature has been higher.

You see, the thing is that some half a century ago a scientific text with graphs inspired respect, well, as a sign that the author of the text understands the subject better than you.
But now graphs and diagrams are often used to create a "smart atmosphere".

What do we have? On the night of February 1-2, 1959, we have a temperature range between -5*C and -16*C (according to the weather station 100 km away). This night (February 1-2) was the warmest, among other days. Why did they froze?

On all other days it was supposedly colder, for example, on February 5 the temperature was -35*C (I don't remember exactly).
It would be logical if Dyatlov's group died that night, and on the morning of February 6 their bodies were found and a criminal case was opened

Sogrin tells how they got off the Moscow-Vorkuta train at a station at the beginning of the route (in 195x-196x), and the air temperature was -56*C. And they began the hike.

Do you understand the difference between -6, -16 and +56 Celsium?

Of course, I understand that there are only three countries on the globe with cold winters (Russia, Canada and Mongolia), as well as Greenland and Antarctica. For some countries such a temperature is rare, and one can imagine the terrible freezing at -20*C, like in Jules Verne's novel "In the Furs' Country".

But lie to me, I once returned from holidays to Moscow on January 9-10 and waited for a train (Mourmansk-Moscow) for 2 hours at such a temperature (-17*C). And as you can see, I'm alive, nothing happened to me in 2 hours.

In Moscow, the temperature -15*C ccurs often in autumn, but crowds of people walk around in single jacket.

The modelling of the timeline is based on the temperature overview below, as available at Dyatlovpass.com.
 


According to this image, the temperature around the cedar/ravine area had been between 'minus 20 degrees C' and 'minus 30 degrees C' from 19 pm to 7 am the next morning.

This is a cold night taking into account the gear and clothing of the group members and a fatal night for those group members who had been in the open air near the cedar/ravine area. 
According to the timeline, the heart of those group members in the cedar/ravine area had stopped beating at 6 am, because their body-core temperature had dropped below 25 degrees Celsius.

My alleged behaviour of the Dyatlov group is described in six posts: "the last two days of the Dyatlov group - a timeline".

Nicely done. It will stimulate discussion.

/// The numbers given in Fahrenheit mean nothing to me. I don't understand them. They are just abstract numbers.  ///

If you live in warm countries, then stop telling fairy tales that you can die at such temperatures
It should be not minus 25, but minus 50.
In the regions of Yakutia, the average January temperature is minus 30. The average is between -20 and -40.
And also, the only indication that it was -30 there is the fact that they died.
There are no other indications that such a temperature could have been there.

Of course, any temperature could have been there, even up to -70.
If we can assume -30, then we can assume -70. The picture will be even more beautiful.

I think that some of the timeline of the loss of body heat works Arjan.

It is evident from the hikers bodies that they suffered frost bite and they were never re- warmed , there is little to argue against the fact that hypothermia played its role in their deaths . How quickly the freezing took place is anyone's guess.

With regards to the ice beds below the bodies , at the time of the first 4 bodies being found , I don't think anyone was documenting things thoroughly, everything was found on the first couple of days of what was a Search and Rescue. I believe Zina was reported to have an ice beard or frost around here mouth area. At least one of the two Yuri's were reported to by lying on fir branches , we can see some of these fir twigs/branches in the autopsy photos that obviously stuck to them.

I wouldn't rule out terminal burying by Zina and Rustem or paradoxical undressing by the two Yuri's. Zina and Rustems bodies look like a natural position to me without movement by others. Rustems hat looks like it's been slightly pushed off from perhaps pushing his own face into a snow drift .

I don't think there would be anywhere enough heat from the fire that was made to cause rewarming shock . However, you have got me thinking and have pointed me in a direction that I've never thought of before.
