The photo above showing a shallow layer of fog on the St. Lawrence River was taken shortly after sunrise on July 28, 2005. This fog is known as "steam fog" and was formed when the warmer river water came in contact with the cool morning air immediately above the river. Often this type of fog appears to rise as misty streamers. Note that the bridge in the background is the northern-most Canadian span of the Thousand Island Bridge -- connecting New York to Ontario.
