A Sundog Sunset Over Beausoleil First Nation, Ontario Royalty-Free Stock Photo

A sundog over Georgian Bay creates the illusion of two setting suns. Sundog are an atmospheric optical phenomenon consisting of a bright spot to one or both sides of the Sun. The sun dog is caused by the refraction of sunlight through ice crystals in the atmosphere. They can be seen anywhere in the world and are most conspicuous when the Sun is near the horizon.
