Snow Characteristics Comments: 

Variable surface conditions to say the least.  The downhill turning was fun and supportable in areas that were freshly drifted in by last night's winds.  S facing aspects held a breakable crust at 9k feet.  Other areas were scoured down to a hard, slick surface.  Dry weather activity?  "Sharpen" those ski and splitboard tuning skills.  :)
