Snowflakes under an electron microscope

Last winter, I wrote about the "frost blossom" phenomenon happening on our sidewalks on a cold December night. Today, while looking up something else on the Internet, I ran across a link to a website with scanning electron microscope pictures (micrographs?) of snowflakes. They're fascinating pictures, especially if you: (1) like snowflakes; or (2) know how an SEM works.
