Trivia Question: Who made the earliest documented mention of snow formation
Earliest documented mentions of snow shape and formation:
The first mention of the hexagonal form in relation to a snow crystal was made in China by Han Ying in 135 BC, in the publication "Hanshi waizhuan".
"Flowers of plants and trees are in general five-pointed. However, flowers of snow, which are called ying, are always six-pointed."

Snowflake instructions diagram the steps to create accurate snowflake designs based upon common scientific snowflake classifications.
Snowflake crystals form when water vapor cools and freezes inside clouds.
You might be surprised to find that snowflakes are not all six-sided.
Here are just a sample of the many forms snowcrystals can take:
There are many reasons that no two snowflakes are alike. Snowflakes form by sticking to each other while falling and blowing through the wind. Factors that influence the size and shape of a snowflake are:
The book: "Rain, Hail, Snow and Sleet" teaches about "precipitation".
It's true, just like human fingerprints are each different, every snowflake is different, although each snowflake is made up of hundreds or even thousands of tiny, identically shaped hexagonal crystals gathered together.
There are an infinite variety of snowflakes. Wilson (Snowflake) Bentley, an American farmer who devoted most of his life to the examination and photography of snowflakes, never found two identical snowflakes.
Snow crystal forms generally fall into broad categories, or Snowflake and Ice Crystal Classifications which are used to create a common form of reference to describe snow crystals.
The simple answer: Avalanches Happen
Global Snowflake Network Scientists are enlisting volunteers to document the shape of snowflakes around the world.
Antarctica is the coldest place on earth. The next coldest places are a few areas in Russia.
The snowflakes that fall on Antarctica hold valuable scientific information about the atmospheric conditions at the time of their formation.
This long-term climatic and environmental information is contained in the dust, chemicals and gas that was trapped in the ice during the snowflake's formation.
The Antarctic ice sheet is a collection of snowfalls that fell over hundreds of thousands of years.
