Skiing down SE exposure with a couple inches of new snow on supportable base until I cut across steepest part of slope near scrub oaks and rocks. The base on steeper more easterly aspect was more saturated and a wet slide fractured right below me. I was able to ski across the slope and stop on top of a group of scrub oaks and watch the slide gain momentum and widen. The first point of fracture was about six inches deep and twelve feet wide it widen to about thirty feet, ran 250 feet and had a debris pile at the bottom three to four feet deep.
