Earlier
in the day I had noticed 'snow'. That is, it resembled that tiny droplets of rain called 'drizzle', except I cold see by the light reflecting off it that it was actually a lot was teensy little ice crystals, smaller than snowflakes.
Then I started seeing these needle like ice formations falling from what seemed the sky, but that was not quite correct as I discovered from further walking around.
They were growing all over bicycles on the Kinkerstraat bridge, and I could see further, but not so easy to photograph, that all of the limbs of trees looked like this this morning.
All afternoon, these tiny little ice crystals were breaking off the trees and probably pipes and such on buildings, blown into the air, and falling like snow, and where it was cold or not salty, it piled up a bit in various places on the ground and whatnot.
I'm not sure exactly what the proper name for this phenomenon is, but from my knowledge of crystallography, a saturated solution and a low level of vibrations and disturbance is required to grow such long needles. This last day or so, it has not been very windy at all, compared to normal, so I figure this is just like, super steroid charged Netherlands ultramegaSUPERHUZZAHfrost. This is not normal, because the air pressure is much higher here and so is the humidity. Thus I suspect such fancy frost is something rarely seen in most other places.
I noticed them to I'm 200km from Amsterdam to the east. Really beautiful. I was for a walk in the woods. Maybe I'll take some pictures tomorrow, if it's still there.
Edit; It's called: Hoar frost (I looked it up.)

Thank you for posting l0k1. These photographs are lovely.....superb. One usually thinks of snow and even icicles in many forms however these seem to be rare indeed.
All the best. Cheers.

Is this ice thorns usual for Amsterdam? I have never see such in Ukraine.

Yeah, I have seen this before to a lesser degree. The low altitude means high air pressure and higher solubility of water in the air. With minimal wind (note that the thorns tend to find more protected spots to form spectacularly as those ones on the bicycles) the tip of the crystal is not broken or melted and it can continue to grow outwards. I would say that this kind of intense frosting is probably not common in higher altitudes.
I like how you called them 'ice thorns' btw :) Very appropriate name for the way they look.
