Danger of avalanche in the region of Dyatlov Pass Incident is not common. The Kholat Syakhl mountain is not very tall and it is certainly not very steep. Furthermore the opponents of this theory suggest that tourist diaries report a fairly thin snow cover. However these facts doesn't exclude the possibility of a small avalanche in a small area of Dyatlov Pass. A portion of the upper layer of snow could simply shift and role over the tourists as a slab of snow. This could damage the tent and create havoc among tourists who were suddenly trapped underneath several feet of snow. It would certainly explain why the tent was cut from inside. Further retreat from Dyatlov Pass would be necessary if the tourists were worried a second avalanche can strike again. According to the supporters of this theory Dyatlov Group tried to make their way back to the Auspiya river and instead made a fatal mistake by descending into a valley of the Lozva river. After 4 weeks the snow that was rushed down the slope of the mountain was simply blown off by the strong winds that are common in the region. This would erase all signs of a natural disaster.
However this theory about Dyatlov Pass Incident has its gaps. From what we can tell from the naked footprints left by the group everyone seemed to descent with relative ease. It is highly unlikely that three people with broken ribs and flail chest would be transportable at all. And here we see several badly damaged men and a woman walk without problems or even help from any of the members of the group. Secondly these men and women were experienced and well trained. They knew that chances of freezing to death is more likely than getting killed by an avalanche. Although the removal of the damaged tent from an exposed mountain side of Dyatlov Pass was out of the question, they had to retrieve all their warm clothes. And finally if you see on the pictures on February 1st on the left and February 26th (according to Vadim Brusnicin who is sitting on a slope of the mountain with his back toward the camera man) on the right you can see part of the tourist gear that kept its vertical position on the slope weeks after the tragedy stroke. Furthermore the entrance of the tent is clearly elevated. Only the middle portion collapse probably due to hasty escape or weigh of snow simply collecting here.
