Fata Morgana on Lake Ontario in Ajax. Top image shows a regular view and the bottom shows the mirage effect, causing visual distortion to the distant shoreline. Lake Ontario is said to be famous for mirages, with opposite shorelines becoming clearly visible during the events. [33]
Various kinds of mirages in one location taken over the course of six minutes, not shown in chronological order. [a]A mirage is a naturally-occurring optical phenomenon in which light rays bend via refraction to produce a displaced image of distant objects or the sky. [1]
Looming of the Canadian coast as seen from Rochester, New York, on April 16, 1871. Looming is the most noticeable and most often observed of these refraction phenomena. It is an abnormally large refraction of the object that increases the apparent elevation of the distant objects and sometimes allows an observer to see objects that are located below the horizon under normal conditions.
The Bizarre Mirages That Scared Sailors For centuries, sailors on the high seas supposedly saw everything from ghost ships, sea monsters, mermaids, and even sirens: dangerous femmes fatales who ...

By 13,000 years ago the lake had fallen to an elevation similar to the average elevation of modern Great Salt Lake. During the regressive phase lake level declined approximately 660 ft (200 m) in about 3500 years because of a change to warmer and drier climate; this was a lake-level decline of roughly 2/3 of the maximum depth of Lake Bonneville.
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. [1]
The hillingar effect or Arctic mirage is a mirage that occurs when cold air near the surface causes light rays to bend. [1]Light passing from an object through air to an observer always refracts, or bends, in the direction of increasing air density.
