Comments

Attached are several photos of the small dry loose activity that was observed in the area by early afternoon. Avalanche activity pictured is from east and north facing terrain from 9600’ to 10,500’. A few smaller natural point releases are estimated to have occurred during the storm, or with warming this morning. Skier triggered avalanches were slightly larger, including a wider piece from the Seagull, observed in motion. All activity was limited to the old/new interface, and made for very shallow avalanches.
