[2] A katabatic wind is a downslope flow driven by gravity and pressure gradient forces on a cold sloping surface, which is typically cooled by a negative radiation balance. There are also somewell researchedbooks out there - with authors like Donnie Eichar andSvetlana Oss,presenting various theories, thepersonalities ofthe group and the pass itself -this sometimes with great commitment and sensitivity to the persons involved. A change in the weather condition could make thinks more difficult on many levels - with domino effects. Skiing in the trailsof the Dyatlov group - watch ourshort film. From their group diary we know that around noon, on the day beforetheir last campsite on the slopes of Kholat Syakhl, the wind escalated. Inevitably and as we shall see,I believe that this last portion of the event can give us an idea of what Slobodin, Kolmogorova and Dyatlov went through after being unable to save their friends. Not the least does this furthermoreindicate that they werent lost the day before when pitching the tent on the slope a sometimes presumed scenario. And the eventin the Ural Mountainscan in my view perhaps be understood quite rationally. It is furthermore often stated that Lyudmila had blood inher stomachand that this would suggest that she was alive when her tongue was injured - or perhaps evenremoved by any ill-meaning force. ur sleeping bags that could endure temperatures to minus 35, delivered satisfactory. 8) The snow covered mountains of Anaris in Sweden. I personally have always wondered why there were huge deliberate clumps of snow on top of the tent that wasn't in sync with the rest of the snowy landscape. Only some vodka. The question is difficult to answer with the various reports at hand. When pushed down it was poked around and when exposed flesh was present, it wouldattachto the hook. Katabatic winds are most commonly found blowing out from the large and elevated ice sheets of Antarctica and Greenland. What is important to realize regarding falling winds, is that theyappear quickly as opposed to a storm. See the blog of Paul Jorion ( Dyatlov mystery+Paul Jorion ) because I have 2 emails there . he next series of important events are harder to fully comprehend, but likely the experienced group purposely split apart temporarily for survival procedures in the forest. The young men at the fire must have struggled hard to get a fire going, which wasalso evident from their unsuccessful attempts. As well acknowledged, the combination of extremely cold environments and sweaty clothes, can be devastating in keeping the body warm and fit. The probes were provided with a hook. Furthermore, it is not inconceivable that the farends of the tent were also left suspended on their gable supports, this in orderto retrieve the tent later. However - me too, it is like you say the life has been consumed for a long time, figuring things out. Cheers! A tent that is not built for extreme winds, would rather swiftly tear to pieces if confronted with falling winds - this, unless it was saved in seconds. The reason for this misinterpretation stems from the original translation of the word leaning, written by me as hanging (onto a birch). I know they thought they might die in the tent, but surely they would die without their clothes. 11.20. (13)In the case of the Dyatlov group and as indicated, a flashlight was left to shine on top of the snow pile likely in order for the group to reposess the tent as soon as the sudden and chaotic situationgot under control. A Swedish wind record for such wind is for example 81 m/s which was documented in 1992 at the Tarfala research station. I'm personally forever grateful, as my life has been consumed for years trying to make the pieces of this puzzle fit. stersundsposten De frdas till Sibirien 60 r efter mystiska ddsfallen testar utrustningen i Tnndalen: Ingen har tidigare kt strckan p skidor (23 januari 2019). Even though there are fancy models and graphs, the underlying details are very subjective. Of course the local and indigenous people - the, 1) The characteristic tilting trees along the Lozva river drew attention already in early depictions from the 19th century. (21)Studying the body positions of Kolevatov, Zolotaryov and Thibeaux-Brignolle, it seems as if they were lying snugly behind each other to keep warm. SR P3/P4 Vaken med Robert Frank Andreas och Richard vernattade i mystiska Djatlovpasset (intervju med Andreas & Richard efter Dyatlovexpeditionen 2019)10 februari 2019, kl. Biting her numb knuckles, Kolmogorova along with her two friends, finally fell asleep from one of naturesmany sinisteroccurrences- thesomewhat rare but otherwisewell documented, katabaticwind. It isnt easy to let them go. Merits to a great team and kudos to my little Milou for being patient when adventure looms. Andreas had his own personal questions and expectations from such an undertaking. Possibly it was thecourageousDoroshenko himself, as the tallest member in the group,that climbed the tree. Our sleeping bags that could endure temperatures to minus 35, delivered satisfactory. But it will always be up to the viewers to decide. The latter is far more dangerous, I gather. Aside from that your style in investigating and explaining all matters Im relating to this case were just as interesting as the case itself! Snow affected by strong windis also evident in the photos of the three bodies that were buried inthe lower part of the slope. "The Barber" has a local reputation for its coldness. Theabove-mentioned particularsshouldbeconsidered as decisive alternativesto any postulatedinjuriesassociated with events prior to the death of the group. (19)The footprints seen near the tent were on the other hand reported as hollowed. It very much resembled the Dyatlov-groupslast approach from the Auspiya valley and up to the ridge next west of the now named Dyatlov pass. It is important to note though, that as time passed,irrational behavior should be expected. Thanks so much for your time and effort. Well,the one who reads theconcluding theory below,ofwhat I reallythink killed the group, he or she will understand that we really had a big reason to be frightened. For us it was an impossible task and considering that we only skied during one fourth of their total planned time-route, yet aremaining mysterysurroundingthe Dyatlov groupmust undoubtedlybe their exceptional stamina. I think that all this could have been performed within around 90 minutes and with constant movements it is survivable. I only close jokingly comments or too much of the same thing from the same angle - this so that ideas can be equally represented. The most serious fractures are related to the last recovered bodies. This is huge when you consider that the Dyatlov Pass is one of the greatest mysteries of all time! Although, in my opinion it is not really necessary. Actually and as an ironical coincidence, the Anaris accident likewise involved nine persons, two young women and seven menof which one survived. 12 above). The Santa Ana winds are notorious for fanning regional wildfires, including a series of blazes in October 2007 that scorched more than 500,000 acres and killed 10 Any wounds inflicted by the impact ofa"snow slab", also makes the fleeing of1.5 kilometres down to the forest an overreaction- and an unrealictic featin regardof Tibo-Brignolle with his interpreted deadly blow to the head. Kudos to a great production team for presenting our effort in this thrilling manner - not the least for being cartoonized, which really felt awarding. I repeat my supposition did on 3-26-2019 . Photo: Richard Holmgren. Because whatever happened that fearful night over 60 years ago,it is likewise not immune to subsequent storytelling and our timeless need for legends and myths. A Swedish wind record is for example 81 m/s which was documented on December 20, 1992 at theTarfalaresearch station. The buildup of high density cold air over the ice sheets and the elevation of the ice sheets brings into play enormous gravitational energy. Recommended! Su Yen, thank you for your words about our expedition. 20.00, 2021). This was also noticed by the group in 1959. And, many thanks for you comment. Many things have changed - some things stays the same. Katabatic winds are often gentle, but I did Photos: Dyatlov Foundation / Richard Holmgren. Your position of strenght from now on will make you sleep well while they have a nightmare . Photo: Dyatlov Foundation. The same is to say about Dubinina, laying close but in a different angle. This makes the most sense out of everything I have read. 18). A sudden change from strong winds into a fall wind on the slope of Kholat Syakhl, could reasonably have reached wind speeds of about 25-30 m/s. In any case, there wouldn'thave been any time to dress in the dark or to unbuttonthe stiff canvasbefore exiting. Photo: Richard Holmgren When the Anaris-group started the trip, they encountered an outside temperature of around minus 15 degrees Celsius (5 degrees Fahrenheit) with a wind speed of around 6 m/s. This particular day the wind accelerated and the physical situation of the group gradually affected their condition. I felt this was lacking and at the time of writing the theory I felt this was a new approach. Thus, this maybe yet another shortcoming when separating wounds as ante- or postmortem in the original examination. In my scenario I believe that the last three to die, were the three on the slope. Considering the seemingly dimlight (? Denselypacked snow is especially visible around Slobodin,surrounding himin finelayers. As in the case of Zolotaryov, these actions does not rhyme with deadly wounds caused early duringthe ongoing events. When this happens on a slope, this cold dense air starts flowing downhill. The gradient of Kholat Syakhl is furthermore far to gentle and the distance to the top much too short to create momentum. If examined correctly, this would also indicate that the lastthree persons alive, Kolmogorova, Slobodin and Dyatlov died when the windwas still battering from above - this, after experiencing the demiseof their six friends. This is not a wise choice for creating a suitable sleeping surface, but vital to succumb impending winds from above. I fully agree with your hypothesis. Inevitably and as we shall see,I believe that this last portion of the event can give us an idea of what Slobodin, Kolmogorova and Dyatlov went through after being unable to save their friends. This type of falling wind can appear when cold air over a glacier or a mountainous area starts to flow down a gradient. Di certo hanno fatto tutto ci che era loro possibile fare, con competenza e intelligenza. Buthopefully the ideas canprovide a general outline of aperhapsrather commonsensicalevent. Before you can work in a scientific manner, you need to have an idea of what you need to prove. UPDATE (reffering to the new studiesin 2020 and 2021 and a"snow slab" theory). I think these actionsareimportant, because many would argue that fleeing from the tent and warmequipmentin such conditions,would mean certain death. What I'm trying to say here,is not that Ias an archaeologist, believe that Noah's ark lies on top of Mt Ararat - but that we with insight in later and local cultures, yes - even those that are two to three thousand years old can understand whystories involvingSodom, Aaron and Noa were important for the human intellect and became part of the narrative. It wouldnt surprise me if the skis were raised a bit during the time of discovery or in fact, that a falling wind never occurred. (20)The next series of important events are harder to fully comprehend, but likely the experienced group purposely split apart temporarily for survival procedures in the forest. Nancy, mostly these tilted trees are positioned close to the riverbed. Good to hear that it makes sense. Dyatlov Expedition New theory | ARCDOC - Arkeologisk Dyatlov Pass on Vox. emergency? A storm would give you time to dress and secure or dismantle a tent properly. stersundsposten De frdas till Sibirien 60 r efter mystiska ddsfallen testar utrustningen i Tnndalen: Ingen har tidigare kt strckan p skidor (23 januari 2019) The message was sent, it will be published after approval. Thisusually gives symptoms offatigue, impaired coordination ability, confusion and hallucinations. As aflight instructor since 1986, hehas been intensively involved in meteorology since the start. Thank you. similar landscape to the mountains south of Otorten can for example be found in Sweden, in the rolling terrain of Anaris. You are right I think the hardest thing to accept is the fact that they left without proper dressing outer shell and proper shoes. Obviously, this would have been very effective in strong winds as long as the occurrence was momentary. Yes indeed, the skis were found sticking up in the snow and this have also been an indication that it couldnt have been an avalanche or a snow slide. Examples of true katabatic winds include the bora in the Adriatic, the Bohemian Wind or Bhmwind in the Ore Mountains, the Santa Ana in southern California, the piteraq winds of Greenland, and the oroshi in Japan. In the Auspiya valleythe temperature fluctuated between minus 20 and 35 degrees Celsius, with an average temperature of around minus 25 during the days and slightly belowminus 30 during the nights. However, the severe injuries found on the last four recovered bodies should in the case of akatabatic event, be tied to other circumstantial evidence - such as pressure from a collapsed snow shelter and natural decomposition due to three months of exposure in the prevailing environment. Webkatabatic wind, also called downslope wind, or gravity wind, wind that blows down a slope because of gravity. However, perhaps they made one small mistake by not attempting to take their sleeping bags with them. You come out stronger .and more credible because you play fair ! Furthermore, if it perchance was blood in her stomach, it could have been a result of many other causes. katabatic winds directly force retreat The theory is based on theexperiences from our Dyatlov Pass expedition during Jan/Feb 2019 and the factual evidence of an accident that occured attheAnaris mountains in Sweden 1978. I have personally experienced weaker but similar circumstances belowthe glacier of Mt Ararat some years ago. /Richard. J.H. The actual pattern demonstrates heavily wind swept snow, where vortexes have hollowed out scoop-shaped cavities. In February of 1978, dammed cooled air was here put in motion very quickly with devastating consequences for a group of nine skiers. Hej David! Such approaches arenot that common infieldarchaeology but excavations in the Middle East sometimesopen such doors. 18) The retrieved empty bivouac, prepared with branches of fir. In their recent episode Return to Dead Mountain (The Dyatlov Pass Incident - Part 3), their video and Podcast depictsour expedition and new theory of 2019. Oh, thank you Gunnar for these words! Myself,working as an archaeologist and with the background already explained,I naturallycame to approachthe case through matters that were familiar to me. Richard Holmgren explains the katabatic wind on Vox. To the right Andreas Liljegren is seen standing outside our tent, near the position of the 1959 campsite. To the far right the grave of Z. Kolmogorova decorated with flowers. This makes them fall into the river row by row. The canvas of my anorak almost teared apart because of the ripping effect caused by fallingwinds. The rescuers arriving to the scene, described the place as the worst they had ever encountered. (27) The katabatic wind derives from the Greek wordkatabasis (), which means descending. [3] In Greenland these winds are called piteraq and are most intense whenever a low pressure area approaches the coast. Ulcers and multiple bleedings in the stomach as a result of severe hypothermia are quite normal. Leaving the tent's deeply ski-anchored gableswas a good solution as it kept the canvas in place without creating too much of asail. In a photograph from 1959, Slobodin can be seen posing with a burntjacket. More to come later. NOTE! This feeling of constant threat of weather changes and how vulnerable you are in this area, really expanded on this theory. Unlike the group in 1959 we had half of our equipment filled into individual sledges. Photo: Richard Holmgren. You welcomed us in Yekaterinburg and you made it possible for us to reach the Uralswithout any setbackwhatsoever. Moncrieff, (author of mystery & suspense novels) - Modern Dyatlov Pass survivors tell their story, (27 February 2019) The presence of katabatic winds is dependent on radiative cooling of the ice slopes. It is however more likely that all rib fractureswith indications of post-bleeding (which was interpreted as the victims having beenalive when receivingtheir injuries), aregenerated after their death (in line withV. Nagaev). Such presentation will be presented in connection to my page soon and based on a meticulous study by a person familiar to such events and the local geography. Lnk 2 This is furthermore not the kind of respect the Dyatlovgroup deserve-or their surviving relatives for that matter. A warm thanks also goes to Dr. Vladimir Borzenkov for rewarding emails back and forth and for your exceptional knowledge on the Dyatlov Pass - down to the smallest of details and notleast for the work you have done on site. I've just created a podcast for an assignment at school based on your magnificent research and theorisation. So many theories. Are Katabatic winds hours long? (14)Crawling back under the snow covered tent, if possible at all due to the conditions involving a gravity wind, couldnt have helped them - which they wisely and obviously realized. when Georgy took 3rd degree half leg burn(med. In this case the layingtent could perhaps have steered away most of the wind -this protected by thesnow dugout that also shelteredthe folded canvas. An interesting note in the Dyatlov group diary, made a short period of time before the accident, described a relatively warm wind associated to a jet-engine. In California, strong katabatic wind events have been responsible for the explosive growth of many wildfires, including the 2018 Camp Fire and the 2020 North Complex. Possible light phenomenaor spheres reported in the sky thereafter, cannot be associated with a katabatic wind. (24)One may alsostressanother problematic occurrence that is seldomraised. . The missing eyes and a tongue,should be considered a natural cause of decomposition. AvAnna-Lena Laurn. The expression OVERWHELMING FORCE OF DYATLOV that Dyatlov pass.com uses is ridiculous because they are looking for a naturel cause when it is artificiel ( UFO ) and this make them go around in circles and they feed the magical thinking ! In line with the local topography and one of the last entries in thegroup diary, the wind was blowing from the west and as such pushed its way up the back of Kholat Syakhl. If a "snow slab" affected the tent, the non-wounded would likely have hadtime to retrieve essential equipment for the long escape route or if returning to the tent. he second heaviest task regarded the low temperatures in general. According to estimates in 1959, the temperature that the Dyatlov group experienced in the late afternoon and in the evening on the first of February, was between minus 25 and 30 degrees Celsius. Your theory is the most reasonable that I have read. Katabatic Winds Unlike anabatic wind which is an upslope wind, katabatic winds are downslope winds. I mean for a person in his or her best shape, such a climb was probable doable but as you say, considering all the survival work that was performed afore probable made the last ascent impossible. New theories by JohanGaume, Alexander Puzrinand Richard Holmgren. For the Dyatlovgroup the snow depth of their made bivouac(s) was well chosen considering the forceful conditions, but as we shall see, with another devastating effect. Yes, this would be a problem indeed, but we must be careful here. With all due respect, there is little in common with Anaris group, which was caught outside, with jackets, shoes, etc, and tried to go "inside", but could not make a comfort "inside" and died from exposure; and Dyatlov's, which did exactly the opposite. A tent that is not built for extreme winds, would rather swiftly tear to pieces if confronted with falling winds - this, unless it was saved in seconds. 18). (9)We know for a fact, from the series of last photos taken by the Dyatlov group, that their weather conditions worsened. Firstly, we wanted to come as close as possible to the historical event by experiencing night camps during the same days of the year as the group in question thisin a tent with a stove, including at least one night on the slope of Kholat Syakhl. Simulations without explicit longwave radiation show that the blocking influence Im thinking it could have been the case for these guys as well in why they cut the tent. A katabatic wind could initiate when cold air atop a higher point begins to flow downhill, displacing warmer air below. That Dyatlov and his friends followed the natural groove on the slope, all the way down to the edge and into the woodland, points to the fact that they were well aware of the fastest way to an alternative place of "safety". This would explain the snow that was covering the central part of the tent when found. Any such theory is more irrationalthan the incident itself. Anabatic Wind | SKYbrary Aviation Safety Agree your Dyatlov theory, and add some common sense thoughts: fire started when shelters to rest 2 hrs, before occupation/extinguished in less than 90 min. This with dignity. Their shoes were nicely stacked against the westernside of the tent withtheir sleeping positionsclose to each other to keep warm. Cant find anything but I remember reading about it in finnish. Most certainly the bivouac with the four personshad already crumbled before thischallenge- or otherwise we couldexpect the last three tohave used the essential footwear that was foundonthe others. Furthermore, whether skull fractures couldoccur through this kind of probing technique, depends. I will try to answer you in the best way I can and if I can. When we through the Swedish Dead Sea Expeditionfound and excavated the Christian and presumedbishopric of Sodoma, we better came tounderstand the complex narrativeof Sodom and Gomorrah. Do hikers regularly sit around campfire in bare/stocking feet---I feel so !) Its like driving a car on icy roads, you cant just keep thinking of covering all possible causes and outcomes. Inside Katabatic Winds Over the Terra Nova Bay Polynya: 1. According to Vladimir Askinadzi, present at the scene,Zolotaryov reportedly even had a pen and a paper in his hands which gives the impression of being rather in control.

This site is very informative and I would and will recommend it to any of my colleagues wishing to also study this magnificent case. The position of the skies furthermore suggest that they were anchored sideways to the wind - thus only facing the wind with some millimetres. In doing so, the less compacted snow next above the creek was very soft. This further confused me since Maslennikov in the context of the birch sapling mentioned that it looked as if Igor tried to protect himself from the wind and Atmanaki saying that Igor was probably stuck there on the wind-swept snow. It was here that the group departed from their tenth group member, Yuri Yudin.
