Logical analysis of tent cuts

(1/6) > >>

Osi:
The character of the cuts in the tent; It provides logical evidence as to whether the tent was cut while it was intact or in ruins. You need to leave the tent urgently due to danger and you will cut the tent. Let's assume the side wall of the tent is 1.80 cm.
Imagine yourself in a tent.
1- You should make a wide vertical incision from top to bottom.
Or..
2-As a bad choice (90 cm upper part / 90 cm lower part of the tent) you make a horizontal cut from the bottom.
And
If you are in a collapsed tent; You will probably be in a lying position. In this case, you cannot make vertical cuts and the cut you will make will definitely be in the upper 90 cm section of the tent.
Now consider the tent.
The cuts are usually horizontal and at the top of the tent. This situation; They do not appear to be suitable for comfortable evacuation from a sturdy tent. But they are just right for a collapsed tent.

GlennM:
Agreed

GlennM:
Lets take the idea a bit further. We assume they cut themselves out of the tent which was collapsed in the middle. Once outside, a decision was made to leave the tent for the shelter of the forest a long distance away. They could have cut up the tent for individual shawls, but did not. They must have expected to return to the tent and either repair it or head for home. Since they took no provisions, we may assume they intended to return when conditions improved. That could mean waiting until sunrise or waiting out a gale.Either way, it seems clear that going to the woods was a short term solution driven by necessity. At the time, there was no need for skis since that would require dismantling the tent. They couldn't do that anyway. It is a process.

If, as some think, someone climbed the cedar as a lookout, they may have looked for the tent as well as evidence of any additional bulk movement of snow. Personally, I would just retrace my steps to get back to the tent.

Osi:
After the calm and cautious meeting; After the plate hit the tent and flowed down, would they be able to regain it by cleaning and lifting the tent?
Yes.
 However, what psychologically convinces tourists to go to the forest is like the trauma experienced after a traffic accident. While some people continue driving the day after the accident, many people are afraid to get into the vehicle for a long time. Some may have insisted on leaving the tent immediately. I must say that the visibility was very low on the day the tent was set up, they were not sure of the distance to the summit and the forest, and this uncertainty was effective in the decision to abandon the tent. Taking the parts of the tent and taking them to the forest would be like giving the contents of the tent as a gift to nature. It made more sense to buy boots and a coat instead of buying parts from the tent.I have a very strong feeling that there was a heavy snowfall in mild weather starting from the morning hours of

February 1st and continuing all day. This precipitation would add another 60.70 cm of snow cover to the landscape that day. However, I think it turned into a storm and then into a dark cold with no precipitation, starting from the night hours.

Due to the expansion of forests towards the north, the trees on the edges are very young and do not produce good fuel. If you observe old cedar trees in parks, you will see branches with huge leaves on them, as well as many dried leafless branches. These contain plenty of resin and burn well. The aim is to break more branches and throw them down. It is possible to get to the top. In the meantime, you may have the opportunity to look towards the tent. However, you have no chance of seeing it in the dark and fog. I think surveillance is not the primary purpose.

Arjan:
Analysing the last two days of the Dyatlov Group is like trying to solve many fully interconnected Sudoko's.
Assuming one number in one Sudoko as fixed, has consequences for all other Sudoko's.
After setting a few numbers as fixed in one Sudoko, the other Sudoko's may well start to showe inconsistencies.
And then it will be tempting to 'bend the rules' to try re-establish consistency in the other Sudoko's.

Reply on cuts of the tent
The first search party has found the tent with two kind of cuts, many vertical and a few horizontal

The horizontal cut near the (broken?) bamboo ski pole may well have been made to serve as:
- ventilation hole for fresh air in the emergency bivac for a few group members and
- peep hole or signal hole for the flash light on top of the tent in the direction to the cedar/ravine area

The vertical cuts make sense because these provide better temporal repair options for keeping the tent 'waterproof'

As many of us, I consider the snow plate engulfing the tent as highly unlikely, because:
- no traces are visible on the photos made by the first search party and
- the hillside of the tent is not avalanche prone.

In case a pressure wave had hit the tent and compressed the tent on top of group members inside, it may well have given the impression on group members inside that an avalanche had hit the tent.
Even after one cut had made, the 'white out' - caused by underpressure during a second or so after the overpressure had passed during several milliseconds - may have enhanced this impression: in panic the group members have cut themselves free.

Remark:
Details hinting on a blast wave with a pressure wave (kind of soliton) lasting a few milliseconds followed by an underpressure during a second or so:
- Fireballs reported
- Lyudmila's fatally broken ribcage without any signs visible on the photo in the mortuary: until now, I have read no other valid explanation than caused by a blast wave. This photo is fully out of line with the 'falling tree theory', because the ribcage should show the indent of deformation made by the tree hitting her ribcage.
- Foam on the mouth of Yuri Dor. as sign of a developing blast lung
- Damaged veins visible on the arm of Yuri Dor. in the mortuary and on the legs of Zinaida as in the Post Mortem report
- Six group members walking on socks for better grip on an icy surface after refreezing of melted snow caused by the overpressure
- Damaged eyes of Semyon and Lyudmila standing in the ravine near the water due to grid and small particles near the stream accelerated to hypersonic speed by the pressure wave. Remark: in a workshop small particles accelerated by a pressure hose will cause serious damage to eyes, while it will not accelerate objects with a considerable mass. Supervisors in the workshop of Delft University of Technology got very angry when we misused the pressure hose in their opinion.
- if I am not mistaken, one broken bamboo ski pole - snapped by the overpressure of the blast wave - visible on the photo of the tent site. Hint: the word firecracker is derived from bamboo sticks thrown in fire. 

Reply on the assumption of the whole group descending together to the cedar/ravine area
The assumption of the whole group descending together to the cedar/ravine area - at the beginning of the evening has at least three consequences:
1. unconscious/dead group members had been placed in postures within a tight timeframe of 36 - 48 hours by outsiders, because on February 2nd around 5 am all group members had been unconscious
2. a few group members had survived the fatal night for other under a far better condition. The re-erected tent had been one - and maybe only - place available for surviving the cold night.
3. this assumption assumption violates the laws of thermodynamics, see the analysis in the post: Hypothermia - a timeline

A sound logic conclusion is:
Group members may have choosen the re-erected tent to serve as emergency bivac for two or three group members.

If so, these two our three group members may have placed the other group members in postures as found by the search parties.
By far the best candidates for these two or three group members - who had survived the fatal night for the other - are: Zinaida and Rustem.
