There generally isn't a lot of ice where I live now. Enough to skid out in the dark, but not much to photograph--or to describe, since black ice seems to demand an absence of description. It's an unseeable hazard, or a cold mirage, flip side to the illusory oasis all those cartoon desert stragglers seem to see.
Grainy, soft, unremarkable, curious, not-quite-transparent, nowhere close to spring pictures.
What if the water were still moving underneath? pictures.
Look at the rocks people have thrown to test the ice pictures.
How soon do you think it's going to get dark and does ice hold shadow as well as it holds light? pictures.
Even invisible ice demands description pictures.
