Ascended 3 way via Boundary basin. Some slabiness in ascent. Old debris from previous AR. 5 cm new unconsolidated from last night on 15cm wet unconsolidated on the crust (crust at times broke and penetration to knees). Full sun, tried to be speedy to manage the wet loose conditions. Two others reached the peak from resort side just as we got there. They dropped the main chutes, all held well from my p.o.v. Looking at photo, looks like they triggered a wet loose slide as well on opposite side of same cliffband. Partner also took the main chutes. I stayed high left, as I passed the first cliff ~6500, a lot of snow started moving and lost footing quickly; not sure if wet slough or slab (possibly wind slab). Tried to ride out, entrained me and carried me through through the chute and over the cliff. Small slide but in consequential terrain made for a big event. Glad to be able to ride out.
