Before a snowflake melts on your tongue, it makes an epic journey.  This is the story of that journey, step by step, from a single snowflake’s creation in the clouds, through its fall to earth, to its brief and sparkling appearance on a child’s mitten.  Told by a scientist who knows snowflakes better than almost anyone, the story features his brilliant photographs of real snowflakes, snowflakes forming (in the author’s lab), water evaporating, clouds developing, ice crystals, rain, dew, and frost--all the elements of the world and weather that add up, flake by flake, to the white landscape of winter.  Aimed at readers from 6 to 12, the book gets to the heart of one of nature’s most magical phenomena while making the wonder of the snowflake all the more real.
