Shown above is a superior mirage as observed over the uninhabited Fox Islands in northern Lake Michigan. On this early spring day, a layer of warmer air was situated just above the still icy lake water so that nearly horizontal rays of sunlight were bent downward. Colder, denser air acts to bend light toward the eyes of anyone standing on the surface. Thus, the small, flat island (approximately 6.65 sq mi or 17.2 sq km in area) appears above its true position.
