Did you Know? Snow Flakes come in all sizes
The average snowflake can be as small as a penny or as large as a human hair. However, some unconfirmed sources claim they can grow much larger. Witnesses to a snowstorm in Fort Keogh, Montana in 1887 reported seeing milk-pan-sized crystals fall from the sky. If this is correct, they would be the largest snowflakes ever seen, measuring about 15 inches across.
