The Snowflake—Nature’s Messenger of Beauty

fresh snow“No snowflake ever falls in the wrong place.” —Zen Proverb

 

I grew up in southern Quebec, where the first snow of the season often came from the sky in a thick passion. Huge flakes of unique beauty settled on my coat sleeves and within minutes I was covered in snow. I would stand enraptured and study each one as I could.

Snow wraps everything in a blanket of soft acceptance. It creates a dazzling face on a dark Earth. It refuses to distinguish between artificial and natural. It covers everything—decorated house, shabby old car, willowy trees, manicured lawn—beneath its white mantle. It quiets the Earth.

Have you ever gone for an evening walk in the fresh crisp snow, boots crunching, snow glistening in the moonlight? Each step is its own symphony of textured sound. A kind of collaboration with the deep of the night and Nature’s own whisperings.

blizzardSnow is a shape shifter, charging down in a fierce blizzard and as hoarfrost that forms as water vapour migrates up through the snow base on cold, clear nights. Snow is a gypsy, conspiring with the clever wind to form mini-tornadoes and swirling on the cold pavement like misbehaving fairies. It drifts like a vagabond and piles up, cresting over the most impressive structure, creating phantoms out of icons. Some people, fearful of the chaos and confusion that snow brings, hide indoors out of the cold. Others embrace its many forms, punching holes through the snow crust to find the treasure of powder beneath or ploughing through its softness, leaving behind an ivory trail of adventure.

Yet every non-aggregated snowflake forms a six-fold radial symmetry, based on the hexagonal alignment of water molecules when they form ice. Tiny perfectly shaped ice-flowers drift down like world peace and settle in a gentle carpet of white. Oddly, a snowflake is really clear and colourless. It only looks white because the whole spectrum of light bounces off the crystal facets in diffuse reflection (i.e., at many angles). My son, who skies, extols “champagne powder”—very smooth and dry snow ideal for gliding on. On powder days, after a fresh snowfall, mountain trees form glabrous Henry Moore-like sculptures. Skiers wind their way between the “snow ghosts,” leaving meandering double-helix tracks behind them.

It is the herald of change, invigorating, fresh and wondrous. Cars skid in it and squeal with objection. Grumpy drivers honk their horns, impatient to get home; while others sigh in their angry wake. Brown slush flies in a chaotic fit behind a bus and splatters your new coat. Boys and girls (of all ages) venture outside, mischief glinting in their eyes, and throw snowballs. Great battles are fought in backyards where children build awesome forts and defend them with fierce determination.

The Snowflake & Its Morphology

winter walk-stockholmSnowflakes are crystals of pure ice. They grow from frozen water droplets (in the form of water vapour as opposed to much larger raindrops). Water vapour in the air condenses and freezes to add more ice to the newly born snowflake. About a hundred thousand cloud droplets make a single snowflake heavy enough to fall to Earth, says Caltech physicist Kenneth Libbrecht, author of The Secret Life of a Snowflake.

Snowflakes have six sides because a water molecule lines up that way, based on its tetrahedral arrangement. While snowflakes are completely symmetrical with themselves, they don’t match any other snowflake. A single snow crystal consists of millions of molecules of water and the number of ways that these molecules can arrange themselves into six-sided crystals is huge. Each snowflake is unique—just as each person is unique—because it encounters unique atmospheric conditions during its descent. Each one of a snowflake’s six arms undergoes the same micro-condition; but no two snowflakes experience that same condition.

Those who study snowflakes classify them into four main groups: dendrites; columns; needles; and rimed snow.

The dendrite or ice fern is the classic snowflake and the shape most of us imagine for a snowflake. It’s a “plate” snowflake that looks like a star or flower, with small side branches crystallizing from each of the six main branches. Some dendrites display a more intricate fractal arrangement, resembling a fern. Dendrites form in a wide temperature range, depending on saturation of the cloud, from just below freezing (low saturation) to minus 20°C (high saturation).

Resembling pencils, they fall when the temperature is just below freezing, from around minus 5°C to minus 10°C). On one mild winter day in Toronto, nothing but these needles dropped from the sky, covering everything from my coat to my black car with what looked like white “hair clippings.” This kind of snow is quite fluffy and develops when the cold air is drier.

Capped columns form when the weather is a little warmer. Capped columns are basically six-sided columns with two plates on their ends like two wheels on an axle.

Rimed snowflakes are partially or completely coated in tiny frozen water droplets called rime. Rime forms on a snowflake when it passes through a super-cooled cloud.

Photographing the Snowflake

Russian photographer Alexey Kljatov created an ingenious and inexpensive DIY camera rig capable of capturing excellent close-up pictures of snowflakes. His setup includes a board, a screw, some tape, a piece of glass and the lens from an old Russian camera. Alexey describes his creation on his blog Keys to December (Chaotic Mind). Briefly, it features a Canon Powershot A650 and a 44M-5 Helios lens from an old Russian Zenit camera taped backwards to a board.

Alexey has captured impressive images of snowflakes that include most of the forms I described above. His images are simply spectacular. See for yourself.

Alexey describes where he shoots this way: “My shooting place is open balcony of my house. Less than half of it covered by roof, other part is under open sky. When the snow is light, i photograph on the open part, choosing the most beautiful and interesting snowflakes fell on the background, and clean background periodically, when it becomes covered by snow. When snowfall is heavy, usually I photograph under the roof, bringing the background under the snow to catch the new crystals. I was lucky that I have such nice place, where nobody disturbs me and I can return into the house when I freeze.”

Don’t freeze, Alexey!

Alexey has made his images freely available for people to share (without profit) on the Internet. His high res images are also available for a reasonable price FineArt America.com/Pixels.com. You can also licence his high res prints through GettyImages.com, Prime.500px.com and ShutterStock.com or contact him via email. Alexey also endorses a 9×9” size 304-page hardcover book about snowflake photography, written by Canadian professional photographer Don Komarechka. Besides techniques on photography, the book, says Alexey, also includes the science of snowflakes and why we find them beautiful.

Alexey Kljatov

Alexey Kljatov lives in Moscow, Russia. From childhood, Alexey devoured sci-fi and fantasy books by many Russian and foreign authors, and that interest has not waned. Since school, he’s maintained a keen interest in computer programming, studying Assembler, Turbo Pascal and Turbo C languages, and played a bazilion computer games (mainly RPG’s, strategies and first-person shooters). He is an assistant in computer and chemistry classes in a local school. Photography is just a hobby for him, he says. He got interested in photography only when digital cameras became good and cheap enough, and macro photography became his main interest. In the beginning, his subjects were bugs, butterflies and flowers, but then he tried snowflake photography; then snow crystals became his main subject.
