Alta Ski Area and The Center for Snow Science at Alta post images of flakes during winter storms on the Snowflake Showcase web page at Alta.com. Below are samples of a couple of stellar dendrite aggregates from Saturday night. Stellar dendrites have a lot of pore space and can produce a snowfall with very low water content. The Utah Avalanche Center reported that the snow that fell Saturday night had a water content of less than 3%. Cold smoke.

Tim and Cale are working on a new and improved system that will enable 3-D imaging. Add real-time access, and we're going to be able to look at evolving winter storms in a whole new way. One thing that you notice quickly when looking at these images (or snowflakes falling during winter storms), is that the vast majority of snowflakes have taken a beating and are very difficult to categorize. Pristine crystals are the exception and not the rule.
Didn't know that but am not surprised.
