Several different crowns and sub bowls all ran at once with all of them across a 1500' area. Of note is we triggered the slopes from 1500' away in a safe meadow, and the fracture propagated up hill through an extremely thick band of scrub oak and aspen. Storm Slab was made up of HST24", HSTW4.2" plus some wind transport. Any time we stepped of the sleds we would sink up to our waist and collapse the entire meadow that we were in.
