Out of curiosity, I looked back in my training records to compare how different local ski conditions were for Dec 2016 compared with Dec 2015. My sense was, and remains, that Dec 2016 was unusually poor due to thin coverage (and when the coverage is poor, I generally prefer to run and take advantage of low snow levels that way) and the damage from 2 wind events. The comparability of the two periods is somewhat affected by the fact I was out of town for 3 days in Dec 2016.
Dec 2016 - running 35 hours, ski 21 hours
Dec 2015 - running 30 hours, ski 45 hours
Unusual day insofar as it sprinkled very lightly much of the day in town. Rain in January is pretty rare here, and it does get the frogs confused.
Up top the light sprinkles of town were instead light snows. Ski conditions were spring-like, with very firm trails and snow with a high moisture content. Lacking any structure (structure? who needs any stinkin' structure?), my skis were slowish, and I had to borrow a can of kick ass from a friend and take a few whiffs of that in order to power around the trails with the proper amount of fim and fet (f&f). It felt awesome to be out.
