A crisp fall morning. The water has cooled way down. But it’s still warmer than the air. It’s not cold enough yet to be real ice fog. The real deal would be very very rare even during the coldest Michigan weather.

Some call ice fog “pogonip.” Pogonip is an adaption of the Shoshone word for cloud (pakenappah). That’s what The Old Farmer’s Almanc is referring to in December when it says: “Beware the pogonip.”
