Route & General Observations

Photos below sent in to CNFAIC of a cornice fall triggered by a snowmachine, which in turn triggered a slab avalanche below on the West aspect of Widowmaker slide path. No one caught. This slab looks to be a storm slab that did not break into deeper layers in the snowpack. Nonetheless, still a large avalanche. Thanks to Clint Kyffin for passing along his photos!
