Abstract: A snow fence system made of snow itself, intended for use around construction sites, like raised pads, commonly used in oil, mining and construction. The snow fence is built in stages. After the first significant snowfall, the pad is cleared by pushing the snow to the windward side of the pad. The pile is then shaped to make a steep flat wall surface. As snow accumulates behind the fence, it is cleared by building a higher wall in front of the first wall. The new wall is higher than the first wall and it too is given a steep vertical face. As additional snow accumulates, the fence is built out further from the pad, using the material from the excavated trenches to build additional walls. Once the fence is in place, the pad remains virtually snow free from drifting. At the end of the season, the fence simply melts away.
