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.

Snowpack Observation 		Mt. Judah
Donner Summit Area 		Thin, breakable rain curst on the surface up to about 7,800. Fading out higher up. Breakable rain crust along the top of Wildflower Ridge at 7,700'. Several inches of surface wet snow in areas of active tree drippings. Older, well buried wind slab avalanche on Wildflower Ridge. Wind slab avalanche on the E face of Mt. Judah. It appears to have been triggered by cornice collapse and occurred within the past 24 hours. Forecaster
