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 all around of the pad. The pile is then shaped to make a steep flat wall surface on all four sides of the pad. As snow accumulates behind the fence, it is cleared by building higher walls in front of the first wall. The new walls are higher than the first wall and are given a steep vertical face. These snow walls are built on the windward and the opposite sides of the pad. As additional snow accumulates, the fence is built out further from the pad, using the material from the excavated trenches to build additional walls.
