I was the fourth skier on the slope of a spaced out party.  About a quarter of the way down the slope I felt a collapse and saw the flanks of the slab begin to separate.   The slab seemed to be about a foot in depth and 70-80ft across.  I would estimate that the slab was the snow from the 4/19 event that hadn't yet bonded to the old snow surface.
