In the preceding paper, the author reported the outdoor observation results on the surface friction of snow. This time, it is recognized from the laboratory experiments that the changes of water content and rheological properties of snow according to air temperature are the dominant factors to control the values of friction coefficient, μs and μk, and also the roughness and film thickness of the sliding surface and penetration affect those values. Moreover, it is proved by using three different methods that the snow crystals are molten by the heat of sliding friction.<BR>From these results together with those of the preceding experiments, it is concluded that sliding on the snow surface is able to be considered simply as one of the frictional phenomena of organic or inorganic crystals near melting point and not as a characteriftic phenomena of snow.
