+1 The lakes have two layers of ice with slushy snow in between them - that was before our rain last night. It's bottom black ice, then about an inch or so of slush, then 3-4 inches of white, then our snow that got rain melted and glazed last night. When this does freeze (we're in the single digits the end of this weekend), we'll have some strange ice. There'll be faults and stress lines all throughout it. It'll look like a foot of ice, but it's whatever the bottom is as solid black, then some very unpredictable ice on the surface. The rain, the refreeze, will make not very strong ice on top, all riddled with stress points where one freeze bonded poorly to a previous freeze. As I've said before - personally, I'll only gauge the reliability based on that solid black ice at the very bottom - and then take into consideration it has a bunch of dead weight on top of it.
