Skied Falls Cr yesterday. Heavy precipitation, strong winds, constant spindrift, small natural sloughs, frequent small cracking, no natural slab avalanches observed, no sign of ski tracks from previous day.
Skier triggered avalanches of various sizes. One chute slid from the top upon ski cut, breaking at skis, running full length and width, crown height ~ 40 cm, vertical distance ~ 900 ft, crown continued along flanks the length of the chute. Another chute produced many smaller slides some breaking at skis, but others breaking above us, these were smaller and under 40 ft wide and 200 feet long, ~ 30 cm deep. Other chutes skied did not produce slab avalanches. Chutes that slid had ~ NW aspect. Chutes that didn’t slide had N and S aspect. All slides were confined to storm snow. Of note, chutes that slid had been skied the day before.
