I'm going to have to look it up, because I'm curious now. It looks more like fiber optics than ice. Gorgeous, though.
I'm hoping it's not snowing on Christmas day, I have to cross the Appalachians and go home.
And the snow here now is already melting. It kept snowing until 9:30 or so, and now it's 11 and everything's dripping off the roof.
EDIT: that was easy!
