More detailed information about the avalanche: 

Was poking around Panorama dome late this afternoon and while descending a convex roll feature, a large crack shot out from the nose of my snowboard and propagated a wind slab. The crown was 6-8". SS-ARu-R1-D1. It appeared to slide on old frozen sun, possible rain crust that was P+ hard.
