Experiment with raised tracks

These are tracks of skis and snowshoes left by us exactly a month ago when the snow cover was at least 0.5 m thicker. You can see the raised prints. What surprised me is that when the snow melts it doesn't lose the top layer but the relief sinks down. In the last 3 photos you can see 3 occurrences of "snow bloom" which is one of the theories about the orange tinge of the bodies on Dyatlov Pass (see #Orange)
