I was stationed there for 4 long cold years. Cabin fever is a real issue about this time of year. Other bases like this are Minot and Grand Forks.
I had orders there, but managed to stay in Japan.
I was there as well. There were some extreme cold periods of a week or so but also warm intervals due to the warm air “Chinook system” coming over from the ocean. Its common to have a week of 20 degrees followed by -10 for a few days then up to fifty for a week and then down to 30.
We even had a day where it was “Road Condition Red” with 60 degrees and dry on base, 40 and rainy in town and a blizzard out in the missile field.
