Snowflakes Under Microscope

Snowflakes are also often used as symbols representing winter or cold conditions. For example, tires which enhance traction during harsh winter driving conditions are labelled with a snowflake on the mountain symbol. A snowflake was the symbol of the 2002 Winter Olympic Games in Salt Lake City, Utah.
Multiple snowflake symbols are encoded in Unicode: "snowflake" at U+2744 (❄); "tight trifoliate snowflake" at U+2745 (❅); and "heavy chevron snowflake" at U+2746 (❆).
