I triggered this soft slab when I jumped off a cornice onto the slope, I had plenty of speed to ski off the slab before it got moving too fast, and I did not take a ride. The crown was 18 inches at it's deepest but averaged around a foot, 80 to 100ft wide and ran about 300ft. The set up was a wind slab on preserved facets from last weeks high pressure. The slope is a steep shady and N facing at about 9600ft in elevation. It was obvious that there were buried facets in this location on our hike out and they just needed a stiffer slab on top and a trigger to be activated.
