Got pulled into a pitch of steeper terrain and kicked off a storm slab on a SW aspect at a steep, thin convexity just below 1800m. Storm snow moved cleanly on the previous surface crust, but no stepping down. No one carried or buried. Other riders in the parking lot noting similar experiences. Storm snow otherwise skiing beautifully on mellow terrain on top of the former solar crust on W/SW facing slopes.
