Snow Crystals!

While it may be true that no two snowflakes are alike, they do all fall into one of more than sixteen categories, some of which are fern-like, columns, needles, plates and triangular. Snowflakes do not have to have six sides, and most people never knew that they are not all two dimensional. The artificial snow that many skiers are familiar with does not form into a flake but rather as fine droplets. This accounts for why it is less appealing to skiers. Natural snowflakes are formed most perfectly when the temperature is around twenty three degrees Fahrenheit.
