Why do these people always tap with a shovel whenever it snows? You might think they are checking the hardness of the snow, but that is not the case. They carefully cut the accumulated snow into the shape of a column, place a shovel on top, and gently tap it with their hand. At first glance, snow appears to be one large mass, but it is actually made up of many accumulated layers. Since each layer accumulates at a different time, the layers sometimes do not adhere well to one another. Therefore, by tapping the shovel like this and observing the reaction to the vibration, they confirm whether there are fragile weak layers hidden beneath the surface that cannot be seen, thereby avoiding the danger of avalanches before they happen. Only those who understood should click "like."
