The guidelines for this week's photo hunt theme, ripples, suggest attempting to avoid water, sand, and flags. However, the first thing that came to mind was this picture taken in January. The water in our backyard pond was low. The pump would run until the float in the filter box dropped enough to shut it off. Then a little water would flow into the box, raising the float, and turning on the pump. This cycle went on for some undetermined amount of time. The temperature was low enough that a thin layer of ice formed on the surface of the pond. The intermittent action of the pump resulted in the rippling pattern you see in the picture, as the water flowed toward the filter box, which was just below the image.
