Abstract
The most important factor in the studies of various phenomena of deposited snow, such as avalanche or melting, is the physical quality of the snow concerned. The deposited snow is traditionally divided into several kinds of nominations according to the intuitive judgement. But it is necessary to know whether there are distinct differences of physical qualities among them. If there is any distinct difference in physical measurement a new classification based upon the objective measurement will become available.
With specimens collected at various places we measured four physical qualities, density, hardness, grain size and temperature, making a collection of many measured values. We measured the four physical qualities with six kinds of specimens, classified by the traditional intuitive method. And by so doing we here tried to establish some standards for the classification of deposited snow based upon the objective measured values.
