[ The snow - limb'd Eve from whom she came. Tennyson, Maud, xviii. 3. snow-line (snō'lin), n. The limit of continual snow, or the line above which a mountain is continually covered with snow. The snow-line is due primarily to the decrease of the temperature of the atmosphere with increase of altitude. In general, the height of the snow-line diminishes as we proceed from the equator toward the poles; but there are many exceptions, since the position of the snow-line depends not only upon the mean temperature, but upon the extreme heat of summer, the total annual snowfall, the prevalent winds, the topography, etc. For these reasons, the snow-line is not only at different heights in the same latitude, but its position is subject to oscillation from year to year in the same locality. Long secular oscillations in the height of the snow-line are evidence corresponding oscillations of climate. In the Alps the snow-line is at an altitude of 8,000 to 9,000 feet; in the Andes, at the equator, it is nearly 16,000 feet. Between the glacier below the ice-fall and the plateau above it there must exist a line where the quantity of snow which falls is exactly equal to the quantity annually melted. This is the snow-line.

In recent forms the principle of centrifugal force has been utilized for removal of the snow. Snow-plows snub The manly snow- shoer hungers for the tramp on snowshoes. The Century, XXIX. 522.
