SFB via Pitman’s Ridge. Air temps in upper 40s mostly cloudy. First turn after chute entrance released substantial wet surface sluff. I was able to exit skiers right of chute to allow debris to travel length of chute. Additional smaller response on slope skiers right of chute. Sluff down to very firm bed surface in SFB. Wet debris pile still audible and creeping 5-6 mins after initial trigger. Will likely have set very hard over night.
