Early one morning a couple of weeks ago we found an ice growth/formation
in a birds' water dish. The whole dish was frozen solid with a flat
surface. IIRC correctly it had been a dry but dampish night.

There was just the one single column of smooth ice about .5cm diameter
and around 3cm tall, on top of which was a formation of ice "petals",
all of them square and .5 to 2cm across. There are no trees or branches
overhanging the spot where this happened so presumably the ice crystals
built up from moisture in the atmosphere? We have a few photos, which
we took just before it disintegrated as the air warmed.

I've never seen anything like this, and I don't suppose I will again.
Presumably the air temperature, humidity et al have to be precisely at
the right point for this to construct itself?

A peaceful New Year to everybody.
