Red Cone exit gully above Horseshoe Lake

We toured up Red Cone Sunday afternoon. Dropped @ 3:30 pm vis the Littlewood line without complications above tree line. Snow was great! On exit through gully snowboarder triggered small slab on short steep pitch in trees. No one was caught. Snow ran away from rider in gully.... thankfully. We didn't complete any pit tests this tour due to timing. Otherwise we saw no other signs of instability.
