There is no pink snow in the world. Rare pink snow was photographed by aerial photography over PuLecene Glacier near Perizano. Surprisingly, there is a touch of pink in the world of white glaciers, but Italian scientists believe that all this is caused by algae after investigating pink glaciers. Generally speaking, algae on glaciers is not a dangerous phenomenon. On the contrary, it is a natural phenomenon, common in mid-latitude areas in spring and summer, and also occurs at the poles.
