What a great day of skiing, it really doesn't get much better than that.  8 to 12 inches of very low density snow (about 4%) fell overnight.  This combined with the 7 to 10 inches of about 5% snow from Tuesday made for some deep blower conditions. West / Northwest winds during the day were in the high teens and low twenties gusting in to the 30's.  This was easily transporting the light snow at ridgetops and in open exposed terrain above treeline. Visibility wasn't the greatest during the day but we were able to notice several loose snow avalanches in steep terrain that was easily running on the firm hard surface.
