Will be brief with this. If the dpi was a cake then we would have some of the ingredients but no recipe. Here are some if the ingredients:
1. The hikers and their injuries
2. Military
3. Solter's statement which indicates
4. a cover up and that;
5. Some of the bodies were very dirty and washed
I think Solter would have known the difference between smoke and dirt. So let's assume the they were covered in dirt, possibly dried mud. There are not many scenarios that you can make a cake with using the above ingredients. Here is one:
The hikers were camped in the forest low down where it was more sheltered and near the frozen tributary. The stove had been lit in the tent. In the same area the military were undertaking a test of a high energy weapon. Possibly underground, possibly over ground, but it is not the direct impact of an explosion that kills them. In a high energy event (e.g a volcanic eruption) a large amount of melt water, ground vibration can cause liquefaction of the soil and a land slide. If a high energy weapon was being tested in the vicinity, then it might be possible that a similar effect is created, even though the land is frozen. A tumbling mass of mud, rocks, logs decends into the ravine along the same path that the water would take. The tent is pitched near the stream. Those outside shout a warning to anyone in the tent, or maybe they are all in the tent. The Tent is hit with mud and boulders, and the hikers panic inside cutting the battered tent. In their attempt to escape some are burned by the stove which has collapsed and is being thrown about inside. Some of the hikers get out relatively unscathed and make a dash for higher ground. The Yuris scramble up a cedar tree and Dyatlov, Zina and a Rustem make their way up the ridge. Lyuda, and Semyon are hit and crushed by large bolders. Thibo is hit by large boulder to his head. Kolevatove breaks his neck. The tent is significantly damaged.
