Snow bridge
Arc formed of snow across a crevasse / From Wikipedia, the free encyclopedia
For various man-made structures to protect from avalanches, see Snow barrier (disambiguation).
A snow bridge is an arc formed by snow across a crevasse, a crack in rock, a creek, or some other opening in terrain.[1] It is typically formed by snow drift, which first creates a cornice, which may then grow to reach the other side of the opening.
