More detailed information about the avalanche: 

Throughout the Council Mountain area yesterday, we observed quite a number of natural wind slab avalanches, and one large cornice fall. Our pits revealed a lot of graupel, but also some facets and some decomposing surface hoar. Slope cuts produced nothing but minor sluffing, and good riding conditions were found in the protected lower elevations where the snow was much deeper. South aspects picked up a good bit of heat occasionally, but the increasing clouds kept the snow a little cooler. Overall it was a warm day that made us think spring, and our snow pack is starting to reflect the change too. Warmth also was a likely player in the last natural avalanche cycle.
