The following post may be rather long, so be forewarned. It shows the icicles on the soffit over my window during the course of several days, in varying lights and stages of formation. It begins on the day following my post (below), “A follow-up to “Looking through my files …”
… and I was right; it IS gone … well, for all intents and purposes:
But conditions were such that I got some very pretty frost flowers on my bedroom window. I shot a couple of frames:
But later in the day, the sun was full up, and evidently the roof was receiving enough heat to get the snow to melt, but it was still plenty cold, so it began to build a new, big icicle even as the meltwater was running off the roof … you can even see the falling drops:
By that night, it was pretty big, and the residual heat from the sun was gone. It was solidly frozen, and I got a shot of it illuminated by the big sodium-vapor floodlight across the court:
The next morning was grey and cloudy, so there was no sunlight, but it shows really well against the leaden sky:
It never really changed, all day … no sun makes a dull sort of picture, but the next day dawned about the same. I decided to show the building across the court, just to give a certain amount of perspective:
The day progressed, and the skies had a bit more interest than the day before. Who knows? Maybe it will clear.
Just before dusk, I shot another:
Sure enough, the next day showed definite signs of clearing. This is before the sun was fully up:
Here we go! The sunlight is beginning its creep down the length of the icicle. It’s a steady progression:
Fully illuminated, it almost glows with the sunlight.
It might be a good time, now to look at this thing a little more closely:
It’s interesting to see how this ice formation bears the same marks of its formation and growth as do the dripstone columns in limestone cavern complexes, which isn’t really strange, because they form in the same way. Only the time scale is different.
Well, the day was slated to be a warm one, and I was out of the building for a few hours, attending to errands and such, It was very pleasant, but when I got back, this is what I found:
Well, at least it’s getting warmer …
