Snow surface is deteriorating. North facing in upper days was slightly damp mashed potatoes. Skied well at 14:00 where untracked and smooth, would suspect having a skin tomorrow morning. South was mostly supportable at 17:30 descent on slopes<35* on 112mm skis down to about 9,500'. At 9,800' south boot pen was up to the crotch, 70cm or more. Ski pen was only about 25cm. The wet snow/transitional snow/melt freeze corn layer seemed to be about the top 60cm, below that appeared to be older, slightly cooler drier snow.
