Phil, let me clarify. This is what was left after the water/melting snow and road salt drained off the vehicle in the garage. Was wondering if the pattern was due to the salt crystalizing in solution, or is it because of the freezing of the water on the floor which then evaporated? Was the salt drawn into that part of the water that was freezing/crystalizing first? Just thought I would pose this question for the benefit of the many earth/science classes that I'm sure frequent Bob's site.
