The above image was taken by Wilson Bentley, the first person to photograph a snowflake. His first successful photo was taken in 1885, and by the time of his death in 1931, he had taken over 5ooo photographs of snowflakes. You can see some of that collection in the book, Snowflakes in Photographs. Or, examine them closely by visiting SnowflakeBentley.com.
