Ok, “bear” with me on this.
Let’ say that Semyon spots something while outside and grabs his camera and informs the others in the tent as he does so. He and some of the others go outside to see without their shoes and weapons. The beast approaches closer and those outside realise they are in danger and start to slowly move away down the slope. The beast approaches the tent and starts sniffing around the entrance. Those still inside panic because they are trapped and cut the tent to get out. They then also move down the slope. Dyatlov drops his jacket to divert the animal. They then go down the slope to the cedar where they can climb up if needed or build a fire to keep warm and ward off the animal.
There are no traces because the animal doesn’t follow them or at least not in their own footsteps. The snow immediately around the tent does covered any tracks in that area.
It doesn’t eat the food in the tent because something startles it. The tent collapses as it pushes its way in and it leaves.
