For almost a century, W. A. Bentley caught and photographed thousands of snowflakes in his workshop at Jericho, Vermont, and made available to scientists and art instructors samples of his remarkable work. His painstakingly prepared images were remarkable revelations of nature’s diversity in uniformity: no two snowflakes are exactly alike, but all are based on a common hexagon. In 1931, the American Meteorological Society gathered the best of Bentley’s photos and had them published; that work has long been available in a Dover reprint edition. The present volume includes a selection of 72 of the best plates (containing over 850 royalty-free, black-and-white photographs), carefully selected from that larger collection
