P10-2022-Snowflake007 & 008
Lens: Plan 10x objective Camera: K3II Photo Location: Pritchard BC ISO: 400 Shutter Speed: 1/13s

Here are 007 and 008.


008 is a very good example of a split star and my very first time really noticing one. I thought it was neat because the branches had grown at an angle that I am not used to, forming more of a narrower X. This happens because the 6 arms grow on 2 separate plates connected by a column and they can grow at slightly different angles.

You can definitely see the difference in these snowflakes. Do you think that this occurs due to a collision where two flakes fuse together? Great micro captures of very interesting snowflakes. Thanks for sharing.

I most certainly do not understand ice geometry. Yet it really is something incredible to see.

No collisions here. This is just how some form. Same process as how capped columns form, or 12 star crystals, except each cap grows only 3 arms. humidity and temperature have big roles to play in crystal formation. I have one more example of this kind of crystal where the arms grew at normal angles but are clearly different sides of a column.
Crystals that collide and fuse have other characteristics and are usually 3, or more, tiered like in this one below. You can see the two middle plates fused off centre of each other.
3 tiers can form naturally but it's more rare and difficult to observe because the middle tier sees so little growth, being shielded on either side by the other 2 plates

Again, an absolutely mystifying image! Beautiful!
