A killer icicle — I dubbed it the murdercicle on my Instagram — forms around the gutter at the edge of my living room window. It melts and it reforges itself continuously. In fact, much to my surprise, most of it melted away over the weekend, but it stopped me in my tracks today when I noticed what vengeance it had returned with. Like, this thing is eight icicles fused into one. It’s got to be six feet tall. You probably really don’t want to stand under it, if you can help it.
