        skier lucking out today.2 or 3 turns into start zone, slope angle guessed to be 45 degrees,slab pulled 60 ft wide avg 16" deep with a portion of slab looking as if it stepped down to old faceted bed surface (repeater path) making for 30" crown. Only able to get 200' close, light was weird so step down may be incorrect. Looked like skier was moving slowly and able to self arrest. Breaking at skiers feet about 45 deg, slope in which they self arrested well over 40 deg not pulling on skier which would have resulted in horrific ride.
Comments
        Many skier and snowboard triggered slides in cold water, taylor and hells last few days on old surface(nsf and or surface hoar).
