We have just short of a foot of snowfall. With the cold temps, the snow on the roof has stayed consistently solid, and has been slowly sliding off the roof, perfectly curving right towards our windows. Generally the icicles melt well before this is possible. In fact, we have never seen such a thing at our home. This is a photo taken about 10:30 a.m, Monday, Dec. 22, 2008. Within an hour of this photo it broke loose.
