"How full of the creative genius is the air in which these are generated! I should hardly admire more if real stars fell and lodged on my coat." --Henry David Thoreau, 1856 [1] Welcome to SnowCrystals.com! This site is all about snow crystals and snowflakes -- what they are, where they come from, and just how these remarkably complex and beautiful structures are created, quite literally, out of thin air. Snowflake News

We grow our own "designer" snowflakes in the lab year-round, right here in sunny Southern California. It's part of our ongoing research into the physics of crystal growth and pattern formation. View three generations of laboratory-grown snowflakes at our Designer Snowflake Galleries, or watch some Movies of growing snow crystals. Snowflake Physics 
Why do snowflakes look the way they do? Check out the Snowflake Primer to learn about what snow crystals are, how they form, and why they grow into such diverse shapes. Or visit our Frequently Asked Questions page. Snow and Ice Activities 
Beyond skiing, snowboarding, and ice skating.... Here are some unique projects you can do with ice and snow. You might try growing your own snowflake crystals, or photographing snowflakes in the wild. Or perhaps you'd like to try your hand at creating some mysterious ice spikes right in your own home freezer. Still Something ...
