Satan's choice slough

Rode Satan's choice down into twin lakes. Climbing the west/back side of Munk the snow was 15-20cms of dry loose pow over unbreakable crust. It would slough away from the skin track but never propagated. Into Satan's choice the rap in went smoothly, I was expecting to be doing jump turns down crust but was surprised to find it pretty deep and soft in the guts of the chute. I ended up not managing my slough well and got caught and went for a bit of a ride. It probably slid 1.5-2 and traveled 500m down hill.
