The insulation for the floors is installed with the vapor barrier AWAY FROM the (warm, in the winter) living space.
So, during the cold months (the people lived here year round), the warm, relatively moist air from the living space will work its way through the insulation until the dew point is reached, at which time the vapor will condense and form water dropletts.
And then the condensed water is more or less trapped there due to the vapor barrier.
It appears to me as if the house was built with uninsulated floors, and then the homeowners installed insulation after the fact.
