I just saw this on FB, posted by Carl N:
Summitted on 11/8. Perfect summerlike weather and dozens of folks on the trail. Switchbacks had about a foot or more of powder - packed down and not a big hurdle, though it iced up quickly once the sun set, made for a precarious descent. In fact all the trails were ice rinks in the dark, microspikes were a must. Full moon helped with navigation though. Not sure how long this weather will hold, but there may be people summitting on Thanksgiving at this rate.
