Pogonip Redoux

The other morning brought more spectacular frozen fog.  

A product of overnight fog and freezing temperatures this rime ice is sometimes referred-to as radiation fog, valley fog or freezing fog.  It is also called pogonip – a Shoshone word for cloud.    

Ordinarily, fog materializes when there is cooler air coming in contact-with a warmer body of water or moist surface like a swamp or wetland. 

Freezing fog materializes when the air temperature is below freezing and the water droplets in the fog become super-cooled. These super-cooled water droplets stay in liquid state until they drift into contact with a surface they can freeze-to. Grass, twigs, trees, leaves and so-forth. 

From our walk we were quick to capture some images before the sun broke thru and burn it all away.....
