Comparative Images of Snow Crystals

----------


This series of scanning electron micrographs represents newly precipitated and metamorphosed snow crystals. The small circular inserts are the "classical" light microscopic images that have been published by Nakaya, Bentley and others. Magnification figures (i.e. 450x) that are indicated on the micrographs are only true for 8" x 10" images. Bars are accurate for all magnifications.
