Typology of snowflakes. Wilson Bentley photographed over 5,000 snowflakes through a microscope in the late 1800s - early 1900s. Thanks to George Slade for reminding me of this pioneering typological work!

Kudos to Lainna Fader for bringing to our attention! 


…frost flowers, a strange phenomenon where frost grows from imperfections in the surface ice amid extreme sub-zero temperatures…forming spiky structures that have been found to house microorganisms. In fact, the bacteria found in the frost flowers is much more dense than in the frozen water below it, meaning each flower is essentially a temporary ecosystem, not unlike a coral reef…


Spectacular snow patterns

Artist Simon Beck must really love the cold weather! Along the frozen lakes of Savoie, France, he spends days plodding through the snow in raquettes (snowshoes), creating these sensational patterns of snow art. Working for 5-9 hours a day, each final piece is typically the size of three soccer fields! The geometric forms range in mathematical patterns and shapes that create stunning, sometimes 3D, designs when viewed from higher levels.
