Icicles

We have loads of icicles hanging from the roof of our house. With the slope of our house having changed from a very steep 45 degree angle, to a less steep angle of about 25 degrees, we now have the problem of snow taking its own slow time to making its way to the ground and while that has some drawbacks it also has some interesting positives. One of the drawbacks is of course the added weight of the snow to the roof of the house. I think that the roof is still steep enough that the snow will not hang up too long, but I do watch the load. The interesting thing is the really cool formations of snow as the snow slides down the tin roof and hangs over the edge of the roof sometimes as much as two feet before it finally lets go with a huge "thunk" and drops to the roof below or to the ground. I've been watching the process for a couple of days now because temperatures outside have decided to warm, and while we had a quite warm day yesterday, after dark everything cooled down and froze up. The slow progress of the snow sliding off the roof came to a complete standstill and huge hanging drapes of snow stopped sliding and remained suspended in an effort to reach the ground. As it cooled, the snow that melted, from this drape of snow began to form icicles and we have had some really interesting ones. On the North side of the house as the snow slid down the roof it began to curl under and as it did so the icicles that had formed decided to point in a horizontal manner rather than a vertical manner. It has all been quite fascinating to watch. Here are a few pictures for you to look at....
