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 		Largest wind slab avalanche triggered by small cornice piece dropped onto the ENE facing slope. A secondary slide released and that crown is 3 to 4 ft. deep. Small wind slab that propagated all the way around an E-ENE-NE facing test slope. Triggered from a low angle slope on the side. Storm slab in below treeline terrain triggered from the lower angle slope I am standing on. Wind slab in near treeline terrain on an ENE facing slope. We cleaned the box on the sign off at the start of our tour and ~3 hours later 6 to 8 inches of snow had accumulated on the box. Forecaster

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
