Avalanche Details

Skier triggered D2 hardslab on ski cut. slope felt hollow so made a ski cut but wasn't expecting a result of this size. Slab was about 200ft wide and 2 to 16 inches deep. bed surface was faceted snow. as the hard slab started moving it rapidly picked up the loose faceted surface snow lower on the slope and accumulated a fairly large powder cloud and estimated mass exceeding D2 requirements. slab was hollow, hard and tapered like windslab but persistent forms on bed surface. lower down the run at around 2500ft a small sluff triggered a smaller hard slab. except in obvious windloaded areas, there was really only 8-12 inches of faceted snow over the ground up to 3500 ft.
