Zastrugi or “sastrugi” is a term used to describe patterns in the snow that coincide with the direction of the wind. In ground blizzards, snow patterns can actually serve as a compass if one knows the prevailing wind direction. They are also fantastic shapes to photograph. This was taken on Barter Island on Alaska’s northern coast, looking off into the Beaufort Sea.
