right side up was bonded well, but strong gusts and consistent wind coming over the ridgeline, and this is primarily what seemed to move
slope cut showed decent stability on entrance from corniced ridge (they're HUGE), but when slope turned past ~37deg., sluffed out from under me and caused a spill - no injuries or burial, just a stir. recovered and skied it again ~an hour later with no sluffing (other bc'ers had skied the run, as well), but the wind had filled in all the tracks already...
