The reason that such small guard IS effective in restraining such an enormous bank of snow stems from the densifi cation properti es snow bank. Remember that the layer of snow that has the greatest strength immediately adiacent to the roof. The heavier the bank of snow above it the more dense this layer becomes increasing its compr essive tensile and shear strengths adjacent
