Let's say you're standing on a layer of snow that fell days earlier. You're trying to make a footprint by stepping on this snow. In a compacted and hardened snow cover, you either won't leave any trace, or at best, you might get a footprint 1-2 cm deep. Then, using a cutting tool, cut a cube measuring 30x30x30 cm from that area. Crush that cube by slamming it violently against the asphalt, and then fill the hole where the cube was removed with the crumbled snow. Now you have a chance to get a footprint 7-8 cm deep. As a result, the path the group took from the tent to the forest had both natural snow cover and snow that had rolled down the slope and crumbled. The snow was probably fresh. Otherwise, the footprints wouldn't have been possible. On the day we moved to the tent, it started snowing heavily in warm weather. It snowed all night. Perhaps a cornice accumulation or a freshly fallen layer hit the northeast slope of the tent and flowed downwards around 10 o'clock. Then, depending on the slope, the route evolved from the tent down to the divan. After the avalanche stopped, the children got out of the tent. First, they trampled on the natural snow untouched by the slab movement. As they went further down, they trampled on the drifted snow. I think this is the most likely explanation for the raised footprints.
