A mild one will consist of persistent endless fog with sub-freezing temperatures. The worst variety is when it turns into a literal ice fog, coating everything. The first day can be spectacular with ice crystal formations on everything. After several successive days of those bone chilling temperatures, it quickly loses its appeal. The pogonip of 1859 was one of severest on record. The heavy cold fog lasted six weeks. So much frost accumulated on the grasses that cattle could not eat it. In addition, since the first settlers had been accustomed to mild winters, very little hay was put up, and a great many cattle starved to death that winter.
The winter of ’78/’79 was a bad one as well. Living out in Willow Creek Valley it was -18F one night and the fog had been thick for days. The icicles on the barbed wire were a foot long You could hear trees cracking in the woods from both the weight of the ice and exploding from being frozen…
