Much of the state was also unusually dry, according to the NWS. Denali National Park headquarters and McGrath saw their second driest midwinter seasons on record. Fairbanks had, by far, the lowest precipitation (and snowfall) of any December through February in more than a century of climate observations, It snowed 2 1/2 inches in the three months and rained 0.13 inches.

The dog trails are getting icy, not so bad that you can't run them, but it's a lot more interesting when you go out. Going side-ways on the turns puts new perspective on the question "how'd it go today?"
Here's a shot of the dogs taking a rest from the heat. The breaks are a lot longer now so they have time to cool down.
