One of the many quirks of Fairbanks is the temperature inversions that takes place in the Tanana Valley and the surrounding hills. The temperature difference, as the map shows, can be quite substantial. Those living up in the hills, will leave relatively moderate temps, and drive down into increasingly chilling temps and the growing murk of ice fog.

It was -36F at the cabin on Monday morning, which does add to the motivation to return to life in the hills. But the firewood bin is full, the stack robber cleaned and throwing out heat of its own, and overall, life is just fine.
