Hero's Knob/Sweet Sixteen

Busy day in Hero's Knob area. -20 leaving the cars at 8:30, day overall felt quite a bit warmer than forecast, -11 by the time we got back in the afternoon. Skiing was better than expected, 15-30cm powder on top of crust on solar aspects/dense midpack on polar aspects. Looked like some recent dry loose (~sz 1) off extreme terrain across the bowl of the ridge approach, and some older slab debris in skiiers left of Sweet Sixteen. Fairly skiied out by the end of the day.
