These observations document past conditions at a small and variable scale. They are not too 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.

01/05/2022 - 11:30 Mt. Judah Donner Summit Area Snowpack Observation A cloud got stuck on Judah making it hard to see the larger avalanche paths. Ice coated all of the trees all the way to the summit of Mt. Judah at 8200 ft. ECTN on a wind-loaded test slope. Rain crust on the summit of Mt. Judah A thin rain crust existed at all elevations. Settlement cracks around trees showing consolidation in the new snow. Forecaster

Debris from trees on an open lower elevation slope. Blowing snow, clouds, and wind affected snow surfaces on the NE ridge of Silver Peak Signs of wind scouring on a slope that traditionally gets wind loaded. Forecaster
