There is a big difference to think something looked burnt and is burnt. It's why wind or winter burn is called this. Also Ivanov wouldn't have known about the broken ribs until after the autopsy , not when he was at the ravine.
Not only Ivanov, nobody knew about broken ribs and cracked skull until the autopsy. In my eyes it plays in favor of explosion, since Ivanov started to look for an epicenter, melted snow, abd broken trees even not knowing about the injuries of the Ravine 4. Just observing the surrounding territory he started to suspect an explosion. You say the trees were wind or winter burnt. How do you know that? Do you see appropriate lab test in the original case files? It's your word against Ivanov's word, but Ivanov has an advantage, he was on the spot in 1959. And it is very important to note, Ivanov stressed that the trees were singed, not burnt. Yes, there are different types of burns: fire burns, frost burns, wind burns, etc. But 'singed' means lightly touched by fire. So, Ivanov meant fire, and that's why he started to look for explosion's traces.
When you say that Ivanov might had confused fire burnt trees with wind or winter burnt trees, you basically say that Ivanov was not competent. despite his boss says he was an excellent investigator. OK, at least, we cannot say that Ivanov lacked good intuition. The Ravine 4 were found in clear water of mountain creek -- part of untouched nature. However, Ivanov initiated radiation lab test, and (oh, gosh!) the test showed that the clothing was contaminated. Maybe, when looking for epicenter, he was led by his good intuition as well?
As I understand it , Ivanov does not speak about such things until 1990 ( I've been going back and forth across pages of stuff written by other people in articles and the case files , it's a mess ) . It's difficult to know if he's been misquoted.
I don't recall him mentioning broken trees or melted snow and his mention of the trees being burnt or singed is only linked to the article. I don't know how he would find melted snow after 3 months of weather and the thaw of the spring. ( There is mention of melted snow around the fire at the cedar when excavation was taking place).
I do not know what he means by his burnt or singed trees but he supplies nothing else , no other people at the site mention singed trees , especially the Mansi . This might be because it is not unusual for them to see wind burn?. We would have hoped that ivano would have said that he took some cuttings and discussed his observations with those that were their but he doesn't, he keeps all this secret until the 90's when articles and books come out . He writes to the editors of newpapers in a very peculiar way as if egging and teasing that he has a mysterious story.
The article or articles do not make Ivanov sound competent. Who knows why?
Here is the quote ,
"
However, there were no traces of the explosion wave; Maslennikov and I examined this carefully."

Dear comrades!
Perhaps you'll be interested in my information about the events that took place thirty years ago in the Northern Urals. During this time, all information about this event was classified, but now several publications have appeared on it: in the Sverdlovsk regional newspaper "Uralsky Rabochy" and the Kustanay regional newspaper "Leninsky Put." I recently learned that some information was also published in the Sverdlovsk newspaper "Na Smenu." But the fact is that, unfortunately, I am the only one left who knows the true circumstances of this tragedy. The circumstances are in my notes.
We need to make a "presentation" so that you understand the reliability of the information source.
From 1951 to 1962, I worked as a criminal prosecutor in the Sverdlovsk Regional Prosecutor's Office (something like a captain-mentor in the navy). My job description required me to assist in investigating the most complex cases, and I took on some particularly challenging ones. That's how it's done today. In 1959, at the request of the regional prosecutor, Klimov, I investigated this case.
"From 1962 to 1965, I served as the head of the investigative department of the Tselinny Krai prosecutor's office. After the region's dissolution, I became deputy prosecutor of Pavlodar Oblast. From 1968 to 1978, I served as prosecutor of Pavlodar Oblast. From 1978 to 1985 (until my retirement), I served as prosecutor of Kostanay Oblast. I hold the rank of State Justice Counselor, 3rd Class, and am an Honorary Worker of the Prosecutor's Office. Now retired, I am a personal pensioner of republican significance and work as a lawyer for the Kostanay City Legal Clinic. So, it would seem that your source should be trustworthy.
The manuscript does not need to be returned.
Sincerely
Lev Nikitich Ivanov, signature
March 8, 1991"
The rest of the blurb is in the link. I don't even know if this is fake but it really reads like ivanov is implying , if you scratch my back I'll scratch yours. If anything .
It is here that fuel is poured onto the DPI to make a metaphorical explosion with no epicenter in the media, Ivanov seems to be the one that ignites the mystery . Strangely it's devoid of empathy or any factual meaning given his credentials.
The reasons given for the lab tests for radiation are even incompetent and again come years later. If Ivanov was in charge, it does not mean he's an expert on everything he sees. He can't know everything about radiation, avalanches , how cut canvas reacts to being cut under a microscope,nature and wind burn , etc
He was the conductor of an orchestra and waves his batten to the musicians informing them when to play the tune, in other words he was the lead investigator, he should be instructing all the people at his disposal and using all the resources but it seems he didn't?.
