Wind transport of snow, and wind slab development was observed above treeline on Ash Creek Butte today. With moderate to strong westerly winds, easterly aspects above treeline were most subject to wind loading. A very shallow pocket of wind loaded snow failed on a test slope while skinning along a ridgeline (see photo). Snowpack stability was very good near and below treeline, however. Stability tests conducted on a NE aspect at 7400ft in the east bowl of Ash Creek Butte indicated good snowpack structure, high strength, and low propagation propensity (ECTX x2, CTN x2, CTH RP down 45cm).
