More detailed information about the avalanche: 

Avalanche course used a small convexity as a test slope and intentionally triggered an R1,D1 wind slab avalanche on an ENE aspect of Panorama Dome this afternoon. Slab thickness ranged between 6" and 12". Incline in the start zone = 45 degrees. Moderate SW winds were effectively transporting snow onto NE slopes at the top of the Sherwins until late this afternoon.
