Avalanche

Observed one avalanche that happened this morning. On a North facing aspect that trends NNE. ~12,200’ elevation. Ran 200-300 feet. 80-100 feet across. Parts of it ran to the ground. Seemed to have begun as a smaller avalanche that triggered a larger slab. This is a classically crossloaded gully. Very exposed to direct west wind. This gully also slid during the natural avalanche cycle around Thanksgiving, which was a smaller slide. Pictures attached but the wind makes details difficult.
