Please elaborate on how freezing brine will cause the salts to precipitate out (separate from water?).

I am not aware of any such process.

Are you saying near freezing water will dissolve less salt than warmer water? If so why wouldn't it dissolve it back when it gets warmer?

Hi Doug,

Long time no see,

Brine won't pool over a slope, but why wouldn't it flow over one? Fluids flow over all sorts of steep and vertical slopes on Earth.
