What's with the sideways icicles in Ferndale?
FERNDALE, Wash. - There was an unusual sight amid the snow and freezing temperatures this weekend in Whatcom County this past weekend -- sideways icicles.
Sandy Funkhouser spotted these vertically-challenged icicles on the west side of a home in Ferndale. You might think the wind was a factor -- the cold air was brought in by strong northeast winds blowing out of the nearby Fraser River Valley.

But as the temperatures warmed, the entire bed of snow on the roof began to slowly slide off the angled surface; the weight of the icicles curving around the gutters. It was likely held together by surface tension from water as the snow began to melt a bit.
Sometimes this process can play out in the extreme:
