Our poor broken easvestrough was a line of icicles.
The birch trees with their fine twigs (and some catkins waiting for spring), seem to show the ice best.
Have you ever heard the ice crackle? You can easily recognize an ice storm if you stick your head out the door in the morning, even if you keep your eyes closed, because you can hear it! There's a bit of wind distortion in this, but turn up the volume and see if you can hear the crackling ice.
