It's been a little below my minimum temperature. Five below is tolerable - the US XC national races shut down at -4F; it must be disappointing for the Anchorage hosts of the US XC National Championships to have such a great snow pack then have this cold snap and cancellation of most of the races.
13 below at my Backdoor Trail this afternoon.
There was a nice inversion at Arctic Valley today. 11F above at the Nike weather site (3900 ft el.), at the same time it was 17 below in East Anchorage (200 ft el.)
