These observations document past conditions at a small and variable scale. They are not to be confused with an avalanche forecast. They come from a variety of sources. We can only vouch for the quality of those produced by the SAC forecasters and professional observers.

Avalanche Observation 		Andesite Peak
Donner Summit Area 		The second of two intentionally skier triggered wind slabs in E aspect terrain above treeline. The first of two intentionally skier triggered wind slabs in E aspect terrain above treeline. Two foot crown. 1.75 m (5.75 ft) of storm snow. CTH results with broken failure planes within the storm snow. ECTX in same pit. Signs of storm snow settlement on tree cones at 10am. The second of the two triggered wind slabs. Initial efforts created loose dry. Once the wind slab was triggered from a more prime location, the slab propagated back through the area that had previously failed as loose dry closer to the snow surface. Forecaster
