Snow was taking heat before I traveled up Flagstaff ridgeline around noon. The top 3 inches on south facing slopes became damp and made for some athletic skiing upon exit around 3p as the sun dipped and the legendary zipper crust formed atop of the plethora of powder snow below it. The north half of the compass was a different story, powder persisted with some consolidation since yesterday's travels in the adjacent drainage. East facing stayed preserved in the form of powder with the cold morning temps. 5 star skiing remains.
