Title: Dyatlov vs. Chivruay

Dyatlov Pass incident vs. Chivruay tragedy (https://dyatlovpass.com/chivruay-incident-5)

Why compare incidents that have nothing in common? The Dyatlov Pass incident opens the door for a lot of speculation. If I could discover so much while not believing they are related in any way, then imagine what a blast the media would have. Nor is Chivruay Pass the only one, Hamar-Daban follows on its heels. The renaissance of interest garnered by the Dyatlov Pass incident is now expanding to cover multiple deaths in the mountains under mysterious - or not so mysterious - circumstances. The mystery for many begins by wondering why would anyone venture there in first place. Personally, I enjoyed this research immensely. The Chivruay Pass incident is interesting on its own, and doesn't need the overshadowing mystery of the Dyatlov case.

It would be nice if the negative for this photo of the Chivruay group was found :-

I wish to see more photos in general. This is the only photo we know of, not a single other photo. If they could develop this one there must be a film somewhere. Mark my words - this case is just starting. Malakhov called Borzenkov an secret agent just because this was his first appearance on TV about this case and he was trying to cool down the paranoia. Russians are insane about this case because they have to fill in bigger gaps. We have so many photos and diaries from Dyatlov group, and Chivruay case has only this photo. I don't think a negative of just one photo makes any difference. We need the whole film.

P.S. Just to be clear, all the rest of the photos you see are from other treks, not even the same people.

No photos, no autopsies. Presumably the case is still closed, not public domain.

You should read my article. I am talking about the case files here https://dyatlovpass.com/chivruay-incident-5?lid=1&flp=1#classified (https://dyatlovpass.com/chivruay-incident-5?lid=1&flp=1#classified)
After 25 years documents are destroyed by law unless an investigator takes up on the case. This case was clear and shut. There was no investigation or even if there was, which was usual practice back then - read more of my articles in this order:
https://dyatlovpass.com/dropped-on-orders-from-above
https://dyatlovpass.com/the-route-not-traveled and

This media noise around the case is created now by Russian Channel 1, started by Voctor Voroshilov who unfortunately was brutally killed and this fueled the "mystery". This is why I wrote Dyatloov vs Chivruay (https://dyatlovpass.com/chivruay-incident-5).

For everyone close to the deceased this case was clear - snowstorm, underestimating the rookies, splitting the group in 3.
The investigation, even if there was one is long destroyed. It is very easy to say - conspiracy, they are hiding the truth etc. BS That's not the case here. The only mystery for me is why are they comparing Dyatlov with Chivruay. Dyatlov is the real real McCoy.

no autopsies

There were autopsies because one of the hikers in the tent is said to have oxygen deprivation - they were rapped in this tarpaulin, so there was an autopsy, or at least coroner's external examination. Since there is no case file then it must be classified of 75 years only because 47 years are passed so it can be closed for just 25. Nobody cared till now. Even the twin brother of Anatoliy Pirigov - Vladimir Pirogov is convinced that it was freak incident related to the weather. Victor Voroshilov, the cousin of that same Anatoliy Pirigov wanted some excitement in his life, wanted to be on TV, so he started digging with the help of psychics and esoterics. I ma sure that he was a decent man, he was actually on our forum too. The fact is that in Russia business altercation often end up with blunt force trauma to the head and gasoline.

You telling me? It started as a prologue to Borzenkov's memoirs "Chivruay 1973. How it really happened. (https://forum.dyatlovpass.com/index.php?topic=627.0)"
This is why I took my sweet time to publish it. I was writing Dyatlov vs Chivruay so they can come out at the same time.
I have more to say but it was taking absurdly long time. It is a process. I learned a lot about Dyatlov case while I was comparing it to Chivruay. It doesn't matter how little do they have in common. It is still very interesting article I reckon.

Comparing Dyatlov Pass incident vs. Chivruay tragedy is a nonsend, looking for sensations and lack of respect for families and friend of the victims. The Chivruay tragedy is explained and very logic. Accident as many others all over the world, same as Hamar-Daban tragedy...
Title: Re: Dyatlov vs. Chivruay
Post by: Teddy on May 09, 2020, 12:32:16 AM
PJ, yes, I agree.
Being a mountaineer, can you tell me what do you think made them get up on fist place and then, if there is a sudden change of weather, why would 5 of them leave the tent? Again, I am not asking this Dyatlov perspective, just looking solely on Chivruay incident. Their behavior is still strange to me. Not Yeti and "meryacheniye" - Arctic hysteria, but still... This place, Chivrauy Pass, is not difficult as they make it sounds. Here are photos of the same trek (https://nodima.ru/travel/lovozero2008) KuAI group did. It is a site for treks with kids!
Bad weather can happen anywhere. Some of them were experienced.  Iliya Altshuller didn't take his gloves (and this is confirmed with a photo Borzenkov has). Where were they going? The ones in the tent were in the most disadvantageous place possible for a snowstorm.  Why go up there if the weather is worsening? And then you can still survive if you stay put in the tent, all of them, for 2-3 days. In this case there was no sign of the storm the next day, when they were found by the next passing hiking group. This is a very popular place and no one ever died in this particular way - from the weather. As I said: the Chivruay Pass incident is interesting on its own, and doesn't need the overshadowing mystery of the Dyatlov case.

I have another title for all three incidents - Dyatlov Pass, Chivruay Pass and Hamar-Daban Pass instead of deadly Passes.

I think that in the Chivruay incident the main factor is weather that change rapidly and beyond any expectations. But of course there are other factors that make it tragic too.

Most of the day they was hiking in the Chivruay valley, they were hidden from wind and probably the wind wasn't strong till afternoon or evening. After they walk over the Chivruay Pass and the wind was picking up they not expected it will be that strong till it was too late.
The meteo station reported wind of 150km/h, up in mountains was for sure more, and generally with wind over 100km/h you are not able to walk. The temperature was reported -28C at night and down in valley so even if at the evening was -20C in mountains together with wind of 100km/h windchill (temperature that you really feel) was -40C and with wind 150km/h windchill was -50C. They not expected something like that so wasn't ready for it at all.

So why they decided to go over the Chivruay Pass.
They was hiking few hours by the  Chivruay valley in good weather, made the ascent of 300m vertical to Chivruay Pass, and only in this place they find out the weather is not perfect, there was 3 option:
- go back to Chivruay Valley - the only decision that could save them but they didn't know that yet, and because they just climbed up, nobody want go back there to do it again next day. As well they didn't think about returning because they wanted go with schedule, this is one of the problem with organized groups that you have schedule and you do no want to change it without serious reasons. This was very strong factor in making decisions about going ahead specially in Soviet Union where the route was officially approved, stamped, signed. You had plan and you should follow it, this is common factor with Chivruay Pass and Hamar-Daban tragedy. The weather wasn't that bad yet on Chivruay Pass so they decided go ahead.
-they could go straight down to Kuftuay River but the descent was 40-45 degrees so not possible to do on snow with heavy backpacks without crampons, specially with 4 novice hikers
-take the easy descent by exposed to wind and without fast escape route.
Another problem in decision taking, in this case was a fact that there was 2 leaders(two joined groups) so non of them wanted to take the decision about going back, they look on each other and feel that situation is under control.
So as they decided to go ahead, it was even harder to decide about return even if the weather start worsening. They was going up to the wind so they could relativity easy turn around and go back to Chivruay Pass(going with the wind is much easier) but as the wind increase and temperature dropped that they start suffer from hypothermia and before making the critical decision about return (it wasn't too late yet) one of the members collapsed, wasn't able to walk anymore. This is why they decided to stop and go into the tent. The other 5 more experienced members went to check other possibilities of descent but never returned. At this point the only possible chance to survive for some of them was to return immediately to Chivruay Pass and down to Chivruay Valley. They couldn't survive in this place where was the tent or anywhere around. Even if they will stay all together, they will die, the temperature windchill was below -50C. But again, they didn't know that such a strong wind is coming.

Is hard to blame any of the leaders for what happened there, they die because it was something as "perfect storm". Something similar to tragedy on Everest in 1996 or Peak Lenina in 1974 (nice article, worth of reading: https://edition.cnn.com/interactive/2020/01/sport/russian-climbers-peak-lenin-spt-intl/ )

But why would they lie down on the tent with the windward man holding the end over him and not get in it? Or find sufficient shelter to erect it? It's more mysterious than just extreme cold (imo).

"They were inside a tent made of one piece of cloth" or "Kuznetsov and four members of the KuAI group, who stayed with the tent actually sat on top of the tarpaulin and wrapped the tent around themselves like a taco."
And about the tent: "This is a bag measuring 2 by 1.5 m (6.5 by 4.9 ft). Initially it was made of thin tarpaulin. Later on, when new materials were introduced was manufactured from percale with aluminium coating; weighs 1 kg (2,2 lb). "

So basically it was bivy bag, so they use it in correct way. In high wind it is not possible to erect tent, the terrain around was flat, or almost vertical down. As well, as I written before, I think that they stopped where one of members wasn't able to go anymore, otherwise they could turn around and go with the wind back to the pass - The other 5 members was still able to walk so the wind in this moment wasn't that strong yet.

Where were the ones that could still walk going? That's the the only and main problem with this group. Borzenkov said they were looking for the way down. You don't go scouting in the dark, in the storm and without gloves. If one of the guys can't walk anymore all of the pitch a tent and sing songs till the storm is over. This has happened many times, it is described by Borzenkov (https://dyatlovpass.com/redirect.php?lid=1&pid=19464&flp=1#borzenkov1), it is the survival manual by Lukoyanov - Safety in skiing and extreme winter conditions (https://dyatlovpass.com/resources/340/Lukoyanov.pdf) (see p.122):

"In March 1963 a group from the Moscow hiking club "Spartacus" went through Chivruay-Ladv in the opposite direction - from Umbozero lake to Seydozero lake. Didn't have any problem scaling the steep slope of the cirque. They stopped for a break on top of the plateau. The March sun was warm. They were relaxed. Someone accidentally looked in the direction of the mine: an ominous cloud hung over the Elmorayok Pass. The edges of the grey mass swirled constantly changing its shape. The first gust of wind swept through the plateau. Then snow came blowing. The clouds were growing rapidly already closing half of the sky. The sun faded. The group hurried to the head of the northern stream. A strong gust of wind came over like a big wall. After a short lull, fury began. The snow hit as blast from a giant cannon.
The leader of the group, an experienced skier, G. Shapkin, insisted on stopping the descent and setting up a tent. Not all members agreed, but in the end the decision was made. For three days the group waited, huddled into the tent on top of the plateau for the blizzard to subside. They didn't carry primuses - portable stoves - and couldn't heat their food or melt snow. They had to dig out the tent from drifts many times. Their sleeping bags and clothes were wet. But they didn't fall into despondency and recklessness. On the morning of the fourth day, the March sun rewarded their endurance.
The group met a rescue squad in the forest of the Chivruay valley and they drank a bucket of hot compote. The rescuers showed wholehearted generosity. This case is described in details in their reports. Too bad it was not published. Maybe it would help others."

What we have in the KuAI group are open backpacks, sleeping bags and warm clothes scattered all over the plateau and 5 people walking around like zombies. It doesn't sound normal to me.

The article you posted seems very interesting. I will reward myself by reading it after I finish another crazy sequence of articles I am working on - the interest of the lead investigator in light events in the sky. I already published his piece "Mystery of the fireballs (https://forum.dyatlovpass.com/index.php?topic=473.)", but it turned out that there is a follow up by Stanislav Bogomolov in 1990, and he started answering questions again in 2019, so we need to hear him :) Never been published in English before. He talked to Ivanov himself.

You don't go scouting in the dark, in the storm and without gloves. If one of the guys can't walk anymore all of the pitch a tent and sing songs till the storm is over.
The problem is that when they stopped, it was too late to pitch the tent anywhere around, wind was too strong, but not too strong for walking yet. So the 5 was waiting (4 of them were 17 years old!!! - kids) while the 5 other just look around for descent, as you said, was dark and windy so you not scouting in group of 10 for descent. When the two groups was looking for descent the wind increased to the speed that make walking not possible, game was over. They not expected that the wind will be so strong. The leaders was young(24 and 23) so with not big experience with group management.

What we have in the KuAI group are open backpacks, sleeping bags and warm clothes scattered all over the plateau and 5 people walking around like zombies. It doesn't sound normal to me.
But no use of sleeping bags, no snow wall, even with some of the group clearly able bodied.
When they stopped, they just wanted to wait for the scouters so nobody open backpack, take sleeping bags. When the scouters not returned and wind increased they wasn't able to do much - wind to strong(is really hard to do anything in wind over 100km/h but there was wind much stronger) and they all suffer from hypothermia already, even if they open backpack to take some extra clothes or sleeping bag it could be blown out.
And yes, in high wind, blizzard and dark people are walking like a zombie
They made series of wrong decisions because nobody was expecting that wind will be so strong.
And we can't compare the March 1963 to January 1973 without weather reports, in March they was able to put the tent and stay inside it, wind was below 80km/h I guess and definitely much warmer, maybe even around 0.

Do we know where were backpack from the 5 that went scouting? did they find them at the tent? or somewhere else?

So if all backpack were left at the "tent" it clearly mean the 2+3 went for scouting only but couldn't return to them.
I saw that photo on p.16, the body is without backpack, but it not mean that it was left that the tent, it could be somewhere else.

We don't have such a thorough account of the inventory what was found where. No pics, no diaries, and it doesn't mean there were none. On the show when Borzenkov was asked directly where are the films from cameras, he said that they couldn't account for all of their belongings because (1) the wind blew their stuff all over and (2) the route is very popular and a lot of trekkers pass by. Basically he is saying we found some stuff and shipped it all to Kirovsk. What happened after that with it was i the case files which were destroyed by law due to lack of interest in 25 years. All friends and relatives basically say what you are saying, and although mourned and dearly missed, no one ever questioned the tragedy as anything more than a freak incident. Till last year. And you will witness how this incident will snowball into Dyatlov Pass.
Title: Re: Dyatlov vs. Chivruay
Post by: Teddy on May 10, 2020, 01:47:41 PM
I got carried away and didn't say what Borzenkov answer was - that as far as he is concerned the cameras could still be there under the stones. The plateau is covered with them stones. BUT if we have 1 photos that means there was a film developed and where are the rest of the photos from this films. I don't think the modern media "investigators" are asking the right question which means they are doing it for the ratings.

Now, Komsomolskaya pravda seem to have grown a real interest. I like the Varsegov Natalya and Nikolay. They have been reporting the case for years. She tried to walk barefoot in the snow (in socks), I just don't remember if she did it on the Kholat Syakhl. (changed the link)

All files was destroyed because case was closed and explained - completely normal, if families were not interested of having photos from the last trip nobody keep it.

They definitely was inside the tent, wrapped in it, like bivy bag, it is the only thing they could do in high wind, all modern tents this days are damaged in 150km/h wind so it was not possible for them to do anything else; they just wanted wait a bit first so didn't take sleeping bags out or build some snow wall(not sure there was enough snow to build snow wall - it could be cleared by wind or the structure of snow could be not suitable to build anything from it)
"Another point Borzenkov made was that the five members of the group found inside the tent tried to put more clothes on and take out their sleeping bags out of the backpacks, but the wind blew all items away, and were found scattered all over the plateau." - so when it was very bad, they try to do something, was too late. Looks like that they made reactions to situation but not try to make any projections how it could be in hour, two and five, probably because of lack of experience. Generally it is very interesting that a leadership were given to very young people in Dyatlov Pass and Chivruay Pass incidents, going on a multi-day hike in winter is not an easy thing... quite strange standard in Soviet Union :/

I do not see anything suspicious in this case, the meteo reported wind 150km/h and -28C that evening/night, it is not possible to survive in conditions like that.

It is possible to survive outdoors in extremely low temperatures and taking into account wind chill factor.  But you would still need to be dressed properly to survive for even an hour or more. We dont know the exact Temperature or Wind Chill Factor at the time of the Dyatlov Incident.

I hear you and I am still not convinced as of why and when the 5 split. To me the whole case would be natural* if they climbed up early and stopped for the view. Then clouds started accumulating and they had to go down fast but they were not sure of the point where to go down. The weather could be so good that the 5 didn't even know the danged they are in. Altshuller may have smoked a cigarette and taken his gloves off or not at all. And then comes a flash blizzard, something like a micro burst. The key problem being it happened suddenly. This is teh only way I can explain the 5 being away from the tent and the tent not being pitched when it dawn on them how bad it is.
* According to all calculations - they couldn't have been on the plateau early. Borzenkov said that for the tent to be properly stretched they need trees. There last trees are close to the mouth of Chivruay river.

(https://dyatlovpass.com/resources/340/gallery/Chivruay-incident-07.jpg)

On you remark about the photos and families - I don't think anybody will throw away the last photos of their child. I think we will still see more photos. They will resurface. We are prepared with information we have so far to witness the coverage of this case in media.
Title: Re: Dyatlov vs. Chivruay
Post by: PJ on May 12, 2020, 04:42:47 PM
I think that it not happens suddenly.
I could understand that they didnt want go back to Chivruay Valley so after climbing on Chivruay Pass they keep going as long as they could, they do not allow the option(critical mistake as we know today) that the wind will be too strong for continuing the hike on the plateau. When they find out it is not possible go further they still try to find out other way down instead all returning to Chivruay Valley(another critical mistake), after splitting it was matter of minutes they all get lots and were not able to return because of wind.
In 1996 on Everest and on Peak Lenina in 1974 they made the same mistake: Not take into account the fact that the weather will be very bad, just keeping false hope that will be not that bad as long as it was too bad and too late to do anything. And on Everest and on Peak Lenina the climbers were much more experienced than on Chivruay Pass. Miscalculation. The most common cause of accidents in the mountains.

And that's a wrap. I agree with you that this is the most possible scenario of the tragedy on Chivruay Pass.
Title: Re: Dyatlov vs. Chivruay
Post by: Nigel Evans on May 13, 2020, 12:13:43 AM
i think inexperience combined with the proximity of safety created a deadly result in failure to turn back, the fact that they attempted to access their sleeping bags and clothing but lost everything is either paradoxical undressing or hints at something stranger. If they were inside this tent for shelter (using it as a bivi) then how could they lose all this stuff?

Great article. I finally found the time to read it. Nice presentation and, really, I haven't heard of this tragedy before. It is interesting as a tragedy that happened to very experienced group of strong willed climbers. Nature always has the last word. And the first. I thing it has the whole sentence :)
Title: Re: Dyatlov vs. Chivruay

Nigel, they bivy bag was small, no chance to keep backpacks inside so if they wanted to take out something from it, they did it outside, in full wind. Very easy to lose things on the wind, specially when your hands are frozen already.

Teddy, exactly, even very experienced climbers do mistakes like that. And on Peak Lenin the wind was about 125kh/h and during Chivruay Incident minimum 150km/h.

In the context of our recent discussion about going to mountains in bad weather the current situation on Mt. Everest is very interesting...

This Spring season the Nepal side is closed(no climbers at all) and from Tibet/China side only one Chinese expedition is on the mountain.
-they want climb it to celebrate the 60th anniversary of the founding of the People's Republic of China - high political pressure on climbers
-nobody else is climbing this season so the achievement will be much bigger, not often happens this days to be "alone" on Mt Everest - more pressure on climbers ego

They made already one unsuccessful attempt some days ago, have to abandon it because of avalanche risk, for this week is planned another summit push but...
There is Superstorm forming in the Bay of Bengal and it will move towards Mt. Everest, European Meteo Agencies predict possibility of very high winds and snowfall on Mt. Everest tomorrow and Thursday, China’s National Meteorological Centre gives some warnings but predict much more optimistic weather... so situation is developing...
As every year monsoon is coming to Mt.Everest region around middle of June but sometimes is early as end of May so maybe this is the last chance for summit push in this week...
Climbers already in high camps, first group planning summit push on Wednesday/Thursday night...
Unfortunately history likes to repeat again and again and again, I hope it will not happens this time and all will be safe. Answer will come in few days...

Thank you for bringing this to my attention.

"The more than two dozen Chinese climbers tackling Mount Everest were expected to reach the advanced base camp at an altitude of 6,450 metres (four miles) on Friday, expedition operators in touch with the China Tibet Mountaineering Association (CTMA) said on April 3."

So they are like 25? They are on camp 4?

The group of 12 surveyors that want to measure Everest plan to summit on Friday, probably on Thursday some of guides could summit already or at last fix the route close to summit.
Generally it mean that they must be already very high on the mountain, to make summit push on Friday, all must be in the last camp at 8300 on Thursday. If it will be hit by very bad weather it could be not so good there :/

On the Chivruay versus Dyatlov comparison - I seem to remember reading about the Chivruay victims that some of them , discovered in May/June (4-5 months after the tragic events) had missing eyes, the same as two unfortunate souls from Dyatovlav. Is that true ?

Regarding Chivruay, I read that the bodies of the five skiers that were found outside the tent were found at various distances from the tent, between 300m to 2000meters IIRC.
Is it known if they arrived in those positions by themselves, or if they were thrown by gushes of wind ?

I think that it not happens suddenly.

This quite natural assumption.

I could understand that they didnt want go back to Chivruay Valley so after climbing on Chivruay Pass they keep going as long as they could, they do not allow the option(critical mistake as we know today) that the wind will be too strong for continuing the hike on the plateau.

Yes.

When they find out it is not possible go further they still try to find out other way down instead all returning to Chivruay Valley(another critical mistake),

It is difficult consider it as error. At them was only two real variants of a way: or in a valley of Kitkuai, or in a valley of Kuftuai. In Chivuruaj and on lake Seid they did not want to go down, because they again would break control term to Kirovsk. So was last (1972) year. To go down in a valley of Chivruai it was unsafe, because pass there was only on very narrow site. It was very difficult to get there. However Lida Martina with his the partner tried reconnoiter it. I so think. And not only I so thought in 1973.

after splitting it was matter of minutes they all get lots and were not able to return because of wind.

No. Time at them was much more, but it was not boundless. Therefore it has not sufficed.

In 1996 on Everest

I do not know this case in details. Please give me reference to complete description.

and on Peak Lenina in 1974 they made the same mistake: Not take into account the fact that the weather will be very bad, just keeping false hope that will be not that bad as long as it was too bad and too late to do anything.

I know this case very well and from the very first source - Vladimir Shataev.

And on Everest and on Peak Lenina the climbers were much more experienced than on Chivruay Pass.

These are absolutely different cases and absolutely different conditions. I so think that in both cases experience of participants could not that that to change. It is similar to trigger situation. It is enough get to those conditions and already that is almost impossible that to change.
Miscalculation. The most common cause of accidents in the mountains.

Yes, it and exists.

The fact that they not consider any other variant/possibility because they would break control term to Kirovsk was mistake that cost them the highest price. Going back to Chivruay Valley was the only chance to survive that weather.

This is why I compare this to tragedies on Everest in 1996* and Pik Lenin - in all this cases they following the plan that was made days before, did not allow the option that the weather could be very bad and simply keep going till was too late.

* on Everest in 1996 two commercial expeditions and other climbers start summit push and keep going to the summit despite the fact that they received info about blizzard coming shortly, they even see the clouds but keep hope that they will be able to made it to the summit and back to camp IV. 8 people died on that day/night.

=======================================

The fact that they not consider any other variant/possibility because they would break control term to Kirovsk was mistake that cost them the highest price. Going back to Chivruay Valley was the only chance to survive that weather.

1. It is Always easier say that already happens, than have full idea that will take place then.
2. If weather has changed, when they have already risen on plateau and have passed to place where there was tent, to them remains only 1,5 … 2 km before where they could go under any weather conditions.
3. People always consider that there should be more optimistic scenario, than the nature can create it. They went there in hope that weather will be better. As it was at all the others (some hundreds) groups which went this pass, as to them, and field them. I went there 7 or 8 times and never such weather met. As well as is the others some hundreds groups.

This is why I compare this to tragedies on Everest in 1996* and Pik Lenin - in all this cases they following the plan that was made days before, did not allow the option that the weather could be very bad and simply keep going till was too late.

In each of these cases a situation very different, therefore compare them it is impossible. For example, in high mountains all becomes complicated hypoxia (you should know about it very well). In a case with Shataeva group on Pamir in 1974, was sharp deterioration of health at several participants of group which they have hidden from base camp, and then weather has deteriorated even more, than expected. That is, there is some generality at "Chivruay" and "Pamir" - both groups have got to conditions which were limiting on survival rate. But it is everything that they have the general.
" Chivruay " Group this typical hit in a situation which exceeds group possibilities. They have got in unique for this place and the general statistics position which did not expect. And which do not expect anybody from those who was to them and will be after.
It is necessary to have a wide experience and impossible intuition what not to get to such position.

* on Everest in 1996 two commercial expeditions and other climbers start summit push and keep going to the summit despite the fact that they received info about blizzard coming shortly, they even see the clouds but keep hope that they will be able to made it to the summit and back to camp IV. 8 people died on that day/night.

Thanks. I read before the book of Krakauer and Bukreev. Unfortunately after 1973 and to 1997 I be taught at universities abroad Russia and did not watch till 2000 these publications.
In Russian-speaking article about this case there is detailed analysis of this incident with which I agree almost completely. It is result of bad weather and, partially, some errors at the initial stage of commercial mountaineering on the Himalayas.
The general in all three cases there is that after hit in extreme situation nobody could make so what avoid victims. It did not depend on will and possibilities of heads or other participants.

You are on Vlad! The most recent official Chinese survey in 2005 measured the peak at 8,844.43 metres, not including the snow and icepack on the summit, while Nepal’s official figure includes the Everest’s frosty crown and is four metres higher.

So it is basically 8,844 without the snow cap, but I say that the new measurements will be 8,843 m. Anybody else?

Yes, thank you for the clarification (for other readers).
I read this back in 1980 and 1981, when the First Soviet Expedition to Everest was being prepared. https://ru.wikipedia.org/wiki/%D0%9F%D0%B5%D1%80%D0%B2%D0%B0%D1%8F_%D1%81%D0%BE%D0%B2%D0%B5%D1%82%D1%81%D0%BA%D0%B0%D1%8F_%D0%B3%D0%B8%D0%BC%D0%B0%D0%BB%D0%B0%D0%B9%D1%81%D0%BA%D0%B0%D1%8F_%D1%8D%D0%BA%D1%81%D0%BF%D0%B5%D0%B4%D0%B8%D1%86%D0%B8%D1%8F .
I hope that in this year's Chinese surveyors using space technology will give more accurate results. Judging by publications in technical journals, they can give accuracy of up to +/- 30 cm. But I don't know how they will take into account the thickness of snow, because they can only install the instrument on its surface.
We'll wait for the results. And the details of this experiment.

That it is possible measure in this way is understandable, but it would be good know exactly how and by what method they measured it (snow depth). US devices require some power on the transmitter, and as far as I know, at these altitudes and these (negative) temperatures current sources (or power supply - PS) are very capricious and unreliable. They are tried to be kept warm (inside clothing), but usually even for radio stations the energy is scarce.
But let's be optimistic and hope for the best. I would wish them success in such work.

Does anybody know if there is an official way of measuring mountains that most countries use?

Teddy asked me for a comment on this, so here it is.

When the matter involves cutting edge science and engineering, there is no official way for anything. According to the famous MIT physicist Walter Lewin, any measurement given without its error is a pure rubbish. If we look at the Chinese measurement of the height of Mt Everest from 2005, we can see the number as 8844.43 m +/- 0.21 m (no snowpack on the summit). That at least puts the measurement in a certain range, which could be taken as scientifically rigorous.

While trying to figure out what Chinese surveyors did with the Mt. Everest altitude measurement this year, I was not able to find any publication, showing pictures of their surveying equipment, except one picture taken on the summit with something like a reflecting geodetic prism (see here https://abenteuer-berg.de/en/chinese-surveyors-on-the-summit-of-mount-everest/ ). The Chinese links provided in the tread here do not show any equipment either. Someone can only see Chinese surveyors trying to use oxygen masks at lower altitude.

In a video posted on May 27, 2020, it is said the surveyors are going to use satellite technology.
https://www.youtube.com/watch?v=3qMk1KMv2eI

In another video, 53 surveyors are mentioned to take part in the expedition.
https://www.scmp.com/video/china/3083376/china-sends-surveyors-top-mount-everest-bid-measure-worlds-tallest-mountain
Traditional and modern equipment are credited to be used for the feat.

In a publication from May 28, 2020, there is some more information and pictures. One can see a beacon, but it is not clear if it was brought to the summit. The beacon might be incorporated within the reflector geodetic prism I mentioned above, but that is not clear. Eight surveyors are credited to have reached the summit for measurements.
https://news.cgtn.com/news/2020-05-27/Chinese-measurement-team-reaches-Mt-Qomolangma-summit--QPczn2tmAo/index.html

In principle such measurements are routine and performed for more than two centuries, while the accuracy increases from many tens of meters down to millimeters nowadays. In order to complete a measurement, someone needs a theodolite, which is an optical precision instrument for measuring angles along a horizontal and a vertical planes. The theodolite is placed over a point on the Earth’s surface, which has its cördinates calculated. Level staff is placed on the point of interest that has to be measured. After taking readings, the calculation is trivial, as it relies on simple trigonometric functions as sine and cosine. The real struggle comes with errors determination which are of different types (temperature, humidity, Earth’s gravity, etc. for both points – the referent and the measured ones, and if possible for several points in between.

Modern instruments can work without a level staff, as they emit light or radar signals and measure the time necessary for the reflected signal to return back. They can measure distances directly to visible points on a rock surface, but to strengthen the return signal someone has to place a reflecting prism on the point of interest.

In order the errors in the measurement to be decreased, the point of interest has to be measured from different points, viewing the point of interest at different angles. The reference points has to be with their known cördinates. Such endeavor in high mountainous rugged conditions is a hard task, as heavy equipment has to be carried along long distances, and different teams to work simultaneously from several points beneath the peak, in order to fit the measurement into the short window of opportunity (2.5 hour as said for the surveyors that have reached the summit with their equipment). In addition there should be clear direct visibility between lower points of observation and the point on the summit. According to a friend of mine, who is a professional surveyor, the hurdles in such measurement, by means of a ground method, would be unsurmountable for obtaining a result in the centimeter accuracy. He would expect a tens of centimeters accuracy, with using the most modern equipment and measurements across distances larger than say about 2 km. The shortest horizontal distance between Mt. Everest and any rock ground, north of the summit, that I was able to measure on Google satellite maps, was 3.8 km. The real distance, along an oblique line, would be in the range of 5 km.

All mentioned so far leave space for only one method to be used here – the satellite GPS one. It uses the same basic principles – measures distances between a referent point and a point of interest. Here the accuracy that can be achieved is in the range of millimeters. The points of reference are where the GPS satellites are at the moment of measurement. Their position is constantly measured while satellites fly above Earth at height of 20,000 km. Satellites emit a radar signal and measure the time for the reflection to come back. With light speed known, measurement is easy on the first step. Again, here the most important are the errors, which are numerous – the Earth geoid’s shape, which affects the gravitational force, the direction of satellite movement (ascending and descending), positions of the Moon and Sun, the presence of large snow packs (glaciers = added more gravitational force), etc. All these are aggregated and clients get their real position on the ground. Precision depends on ground instruments and the stationary time at the point of interest. Longer time = more satellites connected = higher precision. If the measurement could be helped by a ground-based geodetic mark with high precision cördinates, the accuracy becomes even higher. That is why the Chinese team used the help of their telecom operator and Huawei – to secure reliable connection for high speed data transfer. To increase the reflectivity from the point of interest reflecting prisms are placed on the ground. They shine bright when radiated by the satellite emitter.

Finally, a few words about tectonics and earthquakes.

The height of Everest is globally accepted as 8848 m. It is measured by an Indian team in the middle of 20th c. In 1975 and 2005 the same height is confirmed by Chinese teams. The second time the reading is 8844.43 m +/- 0.21 m, but if counted the snowpack on the summit as 3.5 m we get the same height of 8848 m. In 2019 the height was measured by a Nepalese team, but results were not announced yet. Nepal and China agreed to announce both results from 2019 and 2020 together.

The tectonic plate of the Indian subcontinent is moving northwards with an annual velocity of ca 5 cm. The collision of the Indian Plate with Eurasian Plate results in the formation of the Tibetan Plateau and its mountainous rim on its south. Part of Tibet is escaping as a triangular wedge moving to the east. In fact Indian plate is driving within the Eurasian Plate, intercalating it. This process causes the Himalayas to rise at high speed. The region of Everest is considered as rising at an annual speed of 6 cm. Since the Indian survey in 1955, 65 years have passed. This would amount to a cumulative rise of Everest of 3.9 m, for this period. If we count only the last 15 years since the Chinese measurement in 2005, we would calculate 0.90 m rise.

Simultaneously the whole mountain range together with the Tibetan Plateau compensate elastically over the Earth’s mantle due to the increase of the crust’s mass (remember India is driven in between layers of the Eurasian Plate (Tibet)). That means the region sinks to some extent, exactly as a loaded ship sinks a little bit in water, but that cannot negate the whole cumulative tectonic uplift. The deflection of the crust/mantle boundary (MOHO) is estimated as −18.3 ± 8.6 mm/year for the main part of Tibet (https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2018JB016334)
That is about 30% of the rising speed of Everest with a negative sign. So if we remove the MOHO deflection we will get even bigger rise.

On April 25, 2015, an earthquake happened, M 7.9 (Gorkha earthquake) in the region of Everest. The earthquake is of the thrust type, what is characteristic for collisional regions around the globe. The active fault surface, which was the source of the quake, is dipping gently to the north, at 11 degrees angle with the horizontal plane (https://www.sciencedirect.com/science/article/pii/S1674984716300027).
The displacement along the fault surface was southward, effectively rising the whole region of Everest, located above the fault surface. The maximum displacement during the quake was of 5.2 m. The average displacement has not been calculated in the article cited above. If take, for instance, the average displacement to be at say 2.6 m, then we can get the maximum and average rise of Everest, only due to the earthquake:

5.2 х sin(11 degrees) = 0.99 m
2.6 х sin(11 degrees) = 0.50 m

Adding this to the average annual rise of Everest since 2005 we can get:

0.90 + 0.99 = 1.89 m
0.90 + 0.50 = 1.40 m

So, to answer at Teddy’s question for the Everest height after 2019 (Nepal) and 2020 (China), I would bet something between 1.5 and 2.0 m rise since the 2005 measurement.
So my expectation is the result to be between 8849.5 and 8850 m (including the snowpack on the summit).

Post by: PJ on June 04, 2020, 03:41:00 PM
Dilov, thank you for great article and explanation.

Just some info what they used for measurements:
"The surveyors, tasked to remeasure Everest, spent about two and a half hours on the summit, planting a survey marker and a Global Navigation Satellite System antenna.
Others measured snow depth and gravity, among other observations, from six points below the summit. The data will go through comprehensive calculations and verifications before being released — a process expected to take at least two or three months."
https://explorersweb.com/2020/06/02/everest-back-to-new-normal-deserted/

"They erected a surveyor’s beacon on the summit. Together with the BeiDou-3 Navigation Satellite receivers, 3D interactive virtual reality, an airborne gravimeter, snow-depth radar and other instruments, it will measure the exact height of Everest."
https://explorersweb.com/2020/05/27/chinese-surveyors-summit-everest/

So looks like they will use the newest Chinese BeiDou-3 Navigation Satellite plus making another traditional readings from 6 points below the summit:
"The Everest altitude re-measurement will use a BeiDou-3 Navigation Satellite System as well as advanced mapping tools. Traditional trigonometric readings will also take place from six different points along the mountain and the Rongbuk glacier. Preliminary measurements have been taking place since early March."

"China Mobile claims that the whole peak will enjoy 5G coverage, beginning this Saturday, when two more 5G stations — the world’s highest — go up at a 6,500m." - I think together with the 5G stations some GPS receivers was installed as well.

PJ, thanks for the new links.

With all that different kinds of equipment brought to the summit, Chinese would secure the most precise measurement of the height so far.

I was not able to find the quotation about "Traditional trigonometric readings" in both sources, but if that would be true, obviously the surveyors took every possible approach to secure the perfect measurement, possible nowadays.

I'm puzzled by the effort being made to exactly measure the height of Everest. It is simply part of the planet's crust whose altitude is known to be dynamic. E.g. whilst most of the world's coastline will see sea level rise in the future, in northern latitudes (say Finland) the sea level will drop as the earth's crust continues to "rebound" from the weight of ice sheets in past Ice ages.

I was not able to find the quotation about "Traditional trigonometric readings" in both sources, but if that would be true, obviously the surveyors took every possible approach to secure the perfect measurement, possible nowadays.
Sorry, I forgot to put link to it. This info was from some earlier article ExplorersWeb

Does anybody know if there is an official way of measuring mountains that most countries use?

Teddy asked me for a comment on this, so here it is.

........................................

Thank you very much for this article. Everything is very clever and detailed.
I especially liked that you cited the W Levin statement, the meaning that which I have been trying for many years to push fans "defining the place tent with the accuracy to millimeter" with the help of vizier and photo welcher printed on the printer.


any measurement given without its error is a pure rubbish.


I also want thank PJ for their additions and comments.
Still, I'm curious about what the Chinese are going achieve

PS. For PJ : what looks more like G5 antenna in the picture? but is not receiver of navigation system. It uses non-directional antennas.

on this photo, the satellite navigation receiver is at the top- you could see white small disc, the other things(colorful lenses) are for optical measurements from below I guess(but I am not expert in this things, probably Dilov could say more about it what is on this photo)

the 5G antennas are big, here is photo from the Everest BC:

I am wondering what power supply they have for the 5G antennas they need quite a lot of power to operate. I think solar panels could be not enough so maybe some radioactive batteries  dunno1

Thank you! You have the interesting post, but because I'm exhausted all the time for today, I'll answer later.
All I can tell you is that the antennas can be of any shape as long as they're covered by radio-transparent protective shells.

Qoute: "Still, I'm curious about what the Chinese are going achieve" WAB

I think since our President has admonished the Chinese and banned Huawei, the Chinese are using a show of force to illustrate that they can put 5G on top of the world. I have read many times that the actual top of Mount Everest is the size of a truck, so these photos are interesting. The President also condemns the Chinese for building small military islands in their own front yard, perhaps the Chinese are showing the U.S. and everyone else exactly where their backyard is, even if this subject is politically incorrect. Or maybe the Chinese are mad because our President blamed them for a virus that has its origins from Mrs. Gates lovely alma mater at Chapel Hill and the lovely Canadian town of Winnipeg. IMHO

As I understood from the accompanying text, they did not put these towers at the top itself, but somewhere near or relatively close to it. I think that having a good connection in this place will be of great benefit to everyone, no matter who did it. Of course, if the owner doesn't make inflated and overstated claims.

I don't know all the details and I don't want to talk about politics here, but if the country itself is doing something on its territory, should it be a subject for instruction from other countries? I think that many threats in the world are very much overstated. Usually that's what they point out when they want to get some benefits for themselves. Very often they want to take advantage of it at the expense of others.
As for the virus, very little is known yet. Many very important virus scientists consider it to have happened naturally. It was created by mutations.
Our scientist Ivan Michurin (https://en.wikipedia.org/wiki/Ivan_Vladimirovich_Michurin  ) said that: "We don't have wait grace from nature..." (c) After him, some of our humorists added: "...after what we did to her..." (c)  grin1 although Michurin spoke further about plant breeding...  grin1
So it's too early to draw conclusions and blame someone. Time will put everything in its place.
If I remember correctly, Colin Powell at the UN showed a test tube with an alleged "bacteriological weapon" accused Saddam Hussein of it. https://en.wikipedia.org/wiki/Bush%E2%80%93Blair_2003_Iraq_memo   .
The war in Iraq has killed more than 1 million citizens, and the information about this weapon has turned out to be a fake.
