Field Guide to Snow Crystals

Anyone who has ever scooped up a handful of snow and looked closely at the individual crystals of which it is composed will want to own this guide book. It describes the types of snow crystals, how they are formed, and how they change after they have been deposited, and explains the various systems of classification that have been developed. Beautiful and detailed photographs taken by the author illustrate crystals and their metamorphism under various conditions.
