May have been two different slabs breaking, one on the ascent of the slope and one and the decent/landing. It looked to me like a snowmobiler had triggered the first slide on the way up the slope, turned around atop the cornice and jumped back into the slope triggering the slide to the north. Looked to be 12-18 inches deep and 150- 200 feet wide.
