These photos demonstrate what happens to vegetation close to a fresh-water lake in below-freezing conditions. The waves which crash on shore spray millions of small water droplets in the air, which rapidly become supercooled and freeze on contact with any surface they come in contact with, like vegetation. If the air temperature is too warm, the water droplets will not freeze on the vegetation, while if the temperature is too cold, the droplets will freeze in mid-air and a dune of ice crystals forms instead.
