Fog and Fall Foliage
November 13, 2006
One of the sure signs of fall, besides leaves changing color, are the steamy plumes rising above lakes, rivers or even moist land during the early morning. The "steam" is really a form of fog, for obvious reasons referred to as "steam fog" or “evaporation fog.” Relatively cold air and warm water are key ingredients for the formation of this type of fog -- most common in autumn. The above picture was taken in October of 2003, overlooking the Otonabee River, part of the Trent-Severn Waterway, south of Peterborough, Ontario. The fog was quite thick over the Otonabee River but didn't completely obscure the brilliant sugar maple trees composing the foreground and background.
The Canada Geese above the hill top are winging their way south -- yet another sign of fall.
