Abstract
In this study, we researched the skier's zone of influence in the new snow cover of low-density. After we fixed a pressure sensor to the snowfall table on flat ground, we simulated snowfall and prepared the snow cover. We measured the increase in pressure on the snow cover by the skier's crushing load. The purpose of this study is to compare the layering of the snow cover: low-density (ρ=46-166 kg m−3) versus high-density (ρ=170-343 kg m−3, Schweizer and Camponovo, 2001). Great compression of low-density snow cover occurred, and that density change was made to the snow directly underfoot ; the other snow remaining unchanged. As a result, the skier's impact was not spread in low-density snow, but was spread in the crushed snow cover. In this way, it is easier for skiers to influence the snow cover when the density of that is low. However, the skier's zone of influence is limited.
