Every time I read over the story, I have more unanswered questions. Loose threads that don't fit anywhere. Today I'm wondering:
Why did Dyatlov fail to file the appropriate papers for the planned route? It was generally known where they were headed, but the specifics were missing when the rescue crew searched the file to determine exactly where to look. Merely an oversight, or something else?
Why did Dyatlov tell Yudin that he thought they'd be a little later than intended coming back? I don't remember anything up to that point which had delayed them. They weren't even half-way through the journey, but Dyatlov already thought they might be late. Why?
Why were there pieces of clothing on the branches of the cedar tree? And what pieces were they, exactly? How big? Did they get torn off when someone scrambled down? Did someone throw them up there? If so, why on earth go to that trouble?
Why, why, why were they off course? Did they decide to climb Kholat Syakhl--at that time of the afternoon? (Why?) Were they trying to avoid something at/in Dyatlov Pass? Did Dyatlov think it would be an easier route? Were their compasses reading wrong or inaccessible for some reason?
The answers may have nothing to do with the mystery of why they perished, of course. And yet I keep hoping that the correct conclusion will provide appropriate answers to these and all the rest of the niggling questions.
I do have a well of questions myself, but not the ones you are listing. Dyatlov did file a route, the UPI sport's club would not have allowed him to go if he didn't. The reason rescuers were looking for thei location was that didn't expect them to have perished so early in the trek. They thought that the group must have had problem after Otorten. See the maps at
http://dyatlov-pass.com/ the first one and the Google map - you check and uncheck the planned and actual route to see the difference. It was well known where they were going. As for why they veered this is another matter all together.
They started very late on Feb 1 and covered only 2.5 miles. Maybe it was late and they decided to pitch the tent where they did. I do not believe they were lost although last photos suggest poor visibility.
Why Dyatlov said to Yudin that they might be late - this is very normal. They were very slow, easily distracted. The entire length of the planned route was 180 km. The
goal was to be back in Vizhay by February 12 and then in Sverdlovsk a couple of days later, on about February 14 or 15. An alternative route from the storage depot up to the Poyasovy crag and its slope, and then to continue moving in a southerly direction to another mountain, Oykachakhl 1322 - the south point of their route, from which they could go east back to Vizhay, and from where they had promised to send a telegram. To me it sounds very plausible to expect a delay of 2-3 days.
Re the cedar tree - the branches were broken up to 5 m high suggesting that hikers had climbed up to look for something, perhaps the camp. Forensic tests later confirmed that traces of skin were found embedded in the bark indicating that the pair had frantically attempted to climb the tree snapping off branches until their hands were mass of pulpy flesh.
