Snow is the precipitation of ice in the form of flakes, clusters, or crystal.The first sketch was made in 1550 by Oleos Magnus, archbishop of Uppsala, and in 1635, the first scientific records were made by French philosopher, Rene` Descartes.These snow crystals often fall to the ground as individual units, but in warmer regions they clump together as they fall, creating snowflakes.The pioneer in this advanced technology was Wilson Alwyn Bentley, a farmer in Jericho, Vermont.Snow crystals are formed in the atmosphere at freezing temperatures when water vapor is condensed to ice without passing through a liquid state.Two centuries later, English meteorologist James Glaser produced a drawing that is considered the most accurate image made before the development of photomicrography.Snowflakes are transparent, like glass, and vary in size from .02 inches to 50 inches in diameter.

Snow is the precipitation of ice in the form of flakes, clusters, or crystal. Snow crystals are formed in the atmosphere at freezing temperatures when water vapor is condensed to ice without passing through a liquid state. These snow crystals often fall to the ground as individual units, but in warmer regions they clump together as they fall, creating snowflakes. Almost 50 percent of rain was snow that melted as it entered warmer temperatures on its way to earth.
The study of snow crystals has been going on for more than four centuries. Many people have been intrigued by snow, and in the process of observing its forms and studying its formation, they have created a collection of its images. The first sketch was made in 1550 by Oleos Magnus, archbishop of Uppsala, and in 1635, the first scientific records were made by French philosopher, Rene` Descartes. Two centuries later, English meteorologist James Glaser produced a drawing that is considered the most accurate image made before the development of photomicrography. The pioneer in this advanced technology was Wilson Alwyn Bentley, a farmer in Jericho, Vermont. He began his work in 1885, spending all of his free time outside in the cold taking pictures of snowflakes. By the time of his death 40 years later, he had made 6000 photos, half of which were later published.
From these studies and the resulting data, science has learned much about the snowflake. Snowflakes are transparent, like glass, and vary in size from .02 inches to 50 inches in diameter. Although an infinite number of snowflakes fall every year, no two have been found that are alike. However, all natural snowflakes are six-sided and consist of flat-plated ice crystals. These hexagonal clumps of ice create a winter wonderland in every part of the world each year.
