This is a snowflake, Just...Spectacular
Snowflake-a-Day No. 38
This geometric marvel is a thick, bulky snowflake that would have formed more slowly in lower humidity than its bigger brothers, leading to a few fun features we rarely see. View large!

It’s common for a snowflake to have curved lines or circles – this is caused by inward growth from a thicker outer edge. Thick edges can grow in all directions once they form – outward as well as back in towards the center. If they are thick/tall enough, they can also grow from their top edge, like an overhang. We can see that happen in the 2 o’clock branch, right before the final branches sprout.

Speaking of curves and circles, you’ll notice two distinct varieties here: dark grey/black and lighter grey. The darker ones are on the surface of the ice facing the camera, and the lighter ones are on the reverse side, visible through the ice. The pattern on the reverse side is really remarkable, giving a flower-like feel to the center of the crystal.

Speaking of the center, there is definite three-fold symmetry instead of the expected six-fold symmetry. Even sides are slightly longer than odd sides, a trait that can be much more extreme than this example but it’s fun to notice all the same. This happens when a tiny hexagonal snowflake falls in a more stable direction instead of tumbling randomly and evenly.

One final note: you can see it in many of my snowflake images though I’ve never mentioned it before: shadows. Each of the bubbles in this snowflake cast a shadow onto the rear of the crystal – this can be easily seen in the very center and it illustrates the angle that I photograph the crystal at. Straight on, and you’d see no shadows… this helps each snowflake feel like it has three-dimensional depth, but the angle is also needed to get the light to reflect off the surface of the crystal to reveal all the surface details. :)
