Shallow puddles in hard frost seem to freeze from the surface right down to the ground below the water. As they do so they often form attractive, translucent, curvilinear patches in the ice that contrast with narrow areas of clear ice. At least that's what seems to happen - a physicist would be able to describe the process better and come up with the reason for it. I've photographed these kinds of
frozen puddles before and recent cold weather allowed me to do so again.
