2 feet new Sat. night + area closed Sunday + 8-12 inches Sun. night = an epic Monday morning. There was an hour of rain between the storms, so some exposed areas had wind-stripped hardpack (Herb's Hollow, Tube). Thunder did not open until 9:15, so I made the first 3 untracked runs on Ch. 1. The lower mountain trees still had decent powder midday. The final powderfest occurred when South Bowl opened about 1:30. When Ch. 4 opened at 3PM, it too late, as the sun had already baked it into crud. Fortunately I was on my Volant Chubbs. Overall, my 2nd best day of SoCal skiing in 140 days over the past 23 seasons.
