Your theory is the most reasonable that I have read. /R. I fully understand how difficult is your position but the one who admits is the one you can trust and the future is built with people like you . The hardest to deal with during the trip was undoubtedly skiing through pristine snow with backpacks. In this case we are not even talking about the ice sheet over Antarctica, where such winds are normally considered the strongest. The entrancewas made in a hurry, facing downstream. Where these winds are concentrated into restricted areas in the coastal valleys, the winds blow well over hurricane force,[2] reaching around 300km/h (190mph). In Antarctica, by contrast, the wind is still intensely cold. 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 WebAbstract. (16)With the extremely low temperatures at hand, the Dyatlov groupsocks wouldnt immediately turn wet as long as they moved quickly down to the forest to seek atemporary shelter. So, basically, I agree with the idea that a sudden strong wind is the most probable main cause, I just think that a wind by itself can not make people leave "naked" the relative safety of an undestroyed tent in Siberia; something else had triggered the tragic events. A katabatic wind could initiate when cold air atop a higher point begins to flow downhill, displacing warmer air below. (Extra material from theSwedish documentary - Mysteriet i Djatlovpasset-based on our expeditionand new theory 2019. My own experience from such scenario in the mountains, is that when you leave the skis standing outside a house in the snow during strong winds things are usually thrown around, while the skis remain unaffected. Usually everything should be accounted for in any pathologyreport, but the description of her body shows that no difference to the type of wounds was made when analyzed. 11) One of the last photos taken by the Dyatlov group - approaching their final campsite on Kholat Syakhl. Photo: Richard Holmgren. This had a potential to turn dangerous sincethe air interacting with the highlands was cooled thus becoming denser than the air at the same elevation but away from the slope. In a few regions of continental Antarctica the snow is scoured away by the force of the katabatic winds, leading to "dry valleys" (or "Antarctic oases") such as the McMurdo Dry Valleys. Do hikers regularly sit around campfire in bare/stocking feet---I feel so !) 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. 17). Complimenti. Another type of warm wind occurs on the leeward side of the mountain ranges. Simulations without explicit longwave radiation show that the blocking influence Before the trip we actually asked ourselves how it would be possible to spend 14 hour inside thetent we can assure the reader that we never touched any of the game boards brought along. In fact - it was exactly this that killed the Anaris group, where the only survivor escaping the shelter, was the only survivor. 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. o, what was it then that happened at Anaristhatunfortunate day of February the 24th in 1978? You have a lot of interesting angles to complement the understanding of the case. The Anaris groups warming equipment stayed in their backpacks which were not reachable due to their numbhands. Katabatic winds are most commonly found blowing out from the large and elevated ice sheets of Antarctica and Greenland. It is important to note though, that as time passed,irrational behavior should be expected. -on the Swedish Television (SVT-Play). Thisusually gives symptoms offatigue, impaired coordination ability, confusion and hallucinations. y hypothesistries to explain most of the strange phenomena that surround the mystery of the Dyatlov pass - such as why the tent was cut from the inside, why they left the tent and couldnt get back, and why they fled ill-dressed - many without shoes. Dagens Nyheter - Svensk expedition i Djatlovs fotspr exakt 60 r efter desnatten (10 oktober 2019). 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. However the basis of more measurable facts such as the probability of a katabatic wind or not can actually be investigated in depth. Lnk: https://sverigesradio.se/avsnitt/1231912 The ancient city of Petra in Jordan. at each end of the tent still upright as well? 18). In the not too distant future your good judgement and fairplay will be emphasized . this protected by thesnow dugout that also shelteredthe folded canvas. Theyre wrong. 20.00, 2021). The last four bodies recovered in early May, 1959. It is based on our skiing to and stay on the pass in 2019 - and thetheory presented below. In the next minute or even seconds, the wind got so strong that any tent would have blown away or into pieces - this when the gravity windtipped over Kholat's northwestern edgefrom the adjacent western valley. The other bivouac,retrieved on May 5th, was less evidentbut contained the four lastly recovered bodies. Thanks - Cheers! You welcomed us in Yekaterinburg and you made it possible for us to reach the Uralswithout any setbackwhatsoever. The presentation is far from a scientific one as you can see and I share this with many other theories. ARCDOC, Archaeological Documentation. As aflight instructor since 1986, hehas been intensively involved in meteorology since the start. That would have been a blow. Many of his flights were performedin the United States,Spain, Austria and France, where in the latter case, he achieved a record of 7500m altitude in a glider duringawave flight" with separate oxygen. Photo: Mats Borg, n the photos taken by the rescue team, clear traces of snow affected by strong wind can be seen pointing towards the tent from around the peak of Kholat Syakhl. 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. Therefore I would like to make a statementto the contrary - that, if the weather would have been calm, then any appearing and suddenly disappearing footprintswould really have posed a problem. The Dyatlov Pass Incident -Return to Dead Mountain (Part 3), (2 June 2019). Soon the temperature dropped even further, but the situation really turned devastating due to the sudden acceleration of the wind - this with wind speeds up toat least 20 m/s. I agree with your findings.may God bless them lost souls. Andreas had his own personal questions and expectations from such an undertaking. Many thanks for your comment and input! As in the case of Zolotaryov, these actions does not rhyme with deadly wounds caused early duringthe ongoing events. Yours is the most rational theory I have read. And, thank you so much for your words about the presented material! We can for example learn from their journals that the construction needed overall and constant small repairs. For a brief expositiononthe course of events -. On this site go to Dyatlov case . Read the last one over all because speaks very strongly on this case-problem . Hi Robin! Katabatic Wind A first important indication is given by the analysis of the long records of radiosounding data available in Antarctica: katabatic winds and an unsaturated low-level . The problem is that the original sources are many times obscured. kl. First of all if it would have been a hurricane in the area, we would have known that. For a brief expositiononthe course of events -click on the image. Yes, this would be a problem indeed, but we must be careful here. Like I said before - it is really easy to die on Kholat without any props. This particular day the windacceleratedand the physical situation of the group gradually affected their condition. 17),showing the abandoned tent from northwest, clearly demonstratespatterns ofheavily wind swept snow,where vortexes of wind havehollowed out scoop-shaped cavities - in Russian so calledzastrugi(). It is based on our skiing to and stay on the pass in 2019 - and thetheory presented below. A katabatic wind (named from Ancient Greek (katbasis)'descent') is a drainage wind, a wind that carries high-density air from a higher elevation down a slope under the force of gravity. The latter place is the name of a rolling terrain that bear much resemblance to the passes south of Otorten in the Urals. With temperatures below 50 degrees Celsius at the day of arrival to Vizhay and additionally on the day after having left the area, we were fortunate. 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. Continental orography also constrains the A horrible experience indeed. Actually there was no elaborate plan, except for keeping the woods in mind and to have all gear reachable beside and inside each sleeping bag. Katabatic winds are a common feature of the lower Antarctic atmosphere. In the Fuegian Archipelago (Tierra del Fuego) in South America as well as in Alaska in North America, a wind known as a williwaw is a particular danger to harboring vessels. hus, my theory to the groups death is based on the sudden event of a. ne thing that I want to mention in thiscircumstance, regards the angle of the pitched Dyatlov tent. Our collaborationwill be continued. Many of his flights were performedin the United States,Spain, Austria and France, where in the latter case, he achieved a record of 7500m altitude in a glider duringawave flight" with separate oxygen. Photo: Dyatlov Foundation. These rescuers belonged to the Slobtsov group. Thus, this maybe yet another shortcoming when separating wounds as ante- or postmortem in the original examination. [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. Thanks for your insightful comment. Anything thatsticksup andremainsin that position - will likely stay in the way you left it. Photos: Dyatlov Foundation / Richard Holmgren. Leather andcordsare extremely stiffbecause of the cold andyou need to do this with your bare hands. Excuse me but I don`t see DISCLAIMER on Dyatlov pass.com anymore . I have read your article and it is very good. This prevented warm air to circulate insideand created far too cold sleeping bags. Puttingon our ski-boots inthe pass, during-40 C,took aboutthree to four minutes inacontrolled situation. Subsequently thesurrounding snow was blown away by the wind(photo no. )and last three maybe did not know 4 died in shelter since probably returning to tent for medical aupplies for Georgy/Yuri still alive & exspected of 4 in Den/ bloody knuckles as last 3 and Georgy tore branches from cedar (I think Zina fell for waist injury and hit Rustik & Igor)/and who fell at 15 ftl cliff between slope track & cedar(ice,snow blowing, no gloves,shoes,hats_/and one flashlight left (only 3 for 9 hikers ! I've just created a podcast for an assignment at school based on your magnificent research and theorisation. Ulcers and multiple bleedings in the stomach as a result of severe hypothermia are quite normal. Likely not without life changing damages though. Any body of water near high mountains may be subject to such winds. Thisis indeed a well researched andeye-catchingpresentation, although Ibelieve that the adoption of a "snow slab", whether it occurred or not,is not central to the course of events - that is, fleeing downto the forest and not being able to return. Richard Holmgren, February 22,2019 Let us return to this later. (27) The katabatic wind derives from the Greek wordkatabasis (), which means descending. As Yuri D and Yuri K seemed to have died first, there was no chance for them since they were exposed to winds while making the fire. I hope my theory makes sense among other interesting theories. You and your group are brilliant! Webwhat are the non legislative powers of congress. Thank you for sharing your experience with all of us. Antarctic katabatic winds are strongly modulated by synoptic pressure patterns (e.g., Knuth & Cassano, 2011; Wenta & Cassano, 2020) and in many cases what However, the sacks and bags were never used since they failed to open any of their backpacks alongside an overall chaotic situation. A Swedish wind record for such wind is for example 81 m/s which was documented in 1992 at the Tarfala research station. But it will always be up to the viewers to decide. Perhaps the position of Dubinini froze her in a position of entering the shelter or that she simply slipped away withthe underlying stream during spring from a previous position near Thibeaux-Brignolle. Possibly it was thecourageousDoroshenko himself, as the tallest member in the group,that climbed the tree. Recommended! Vox Media - "Two theories for an unsolved Soviet mystery", (intervju med Richard Holmgren om katabatiska vind-teorin samt med Johan Gaume och Alexander M. Puzrin om snflaksteorin),5 April 2021. We believed that this would ease the weight from the skis and thus prevent us from sinking too deep into the snow - which fortunatelyalso becamethe case. Other regions may have a similar but lesser effect, leading to "blue ice" areas where the snow is removed and the surface ice sublimates, but is replenished by glacier flow from upstream. There's something that bothers me, though, which, perhaps, you can explain. (17)After arriving to the forest and eventually into the area of the large Siberian cedartree, the winds would have still been very strong, but the best possible shelter for waiting out the ordeal away from the slope. katabatic wind anaris 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. In a photograph from 1959, Slobodin can be seen posing with a burntjacket. In this instance it might explain peculiarities in decisions and behavior. 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. valley walls). Hufvudstadsbladet-Svensk expedition i Djatlovs fotspr exakt 60 r efter desnatten (13 oktober 2019). 20) Many thanks to Vladimir and Vladislav for their great hospitality when repacking in the village of Vizhay. Since the density of air is inversely proportional to temperature, the air will flow downwards, warming approximately adiabatically as it descends. A hard time yes, with severe frostbites yes, but the only chance of survival. Cant find anything but I remember reading about it in finnish. As long as anyone believes in what they are saying in regard of the Dyatlov Pass, it is fine with me. The most serious fractures are related to the last recovered bodies. This creates a wind known as a katabatic wind. However, the sacks and bags were never used since they failed to open any of their backpacks alongside an overall chaotic situation. The weather has always been my presumption and especially after experiencing the freezing winds on Kholat. Grazie per le tue parole Erika. ne may alsostressanother problematic occurrence that is seldomraised. The group of two women and seven men were then overtaken by wind speeds up to at least 20 m/s an explosive scenario that erupted out of a rather calm and pleasant skiing tour. Antarctic surface winds display a high degree of persistence with mean directions related to the local topographic configuration of the ice sheet, consistent with katabatic forcing. Lnk 2 Hi Rufus! I would say probably. See Bedtime Stories and the episode Return to Dead Mountain, "The cultural mechanics of mystery: structures of emotional attraction in competing interpretations of the Dyatlov pass tragedy, "Mechanisms of slab avalanche release and impact in the Dyatlov Pass incident in 1959". It is impossible to ask for something stronger . In, This page was last edited on 25 April 2023, at 04:42. In fact - it was exactly this that killed the Anaris group, where the only survivor escaping the shelter, was the only survivor. In addition to this interpretation, the lack of any documented drag marks in the snow should also be considered. The other bivouac,retrieved on May 5th, was less evidentbut contained the four lastly recovered bodies.
