This looks like the scene of a science fiction movie - like the surface of another planet.
This is the result of a rare event - the lake still warm, a sudden extreme cold and windy front coming from the north, the waves wash everything and creates several layers of ice on everything it touches. This is at Edgewater Park near the pier. All plants, rocks, bridges, etc have a very thick coat of ice.
This is almost untouched. It looks very unreal but the most I did on this image was changing a little bit of brightness and saturation.
