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 		Natural wind slab below the summit of Andesite, E aspect, ~8,200'. Appeared to have occurred late on March 24. 6 inches of storm snow available for wind transport in above treeline areas. Dark line is our skin track. Minor cracking on wind loaded test slope above treeline. Forecaster

Snowpack Observation 		Incline Lake Peak
Mount Rose Area 		Large cornices along summit ridge. Note the cracked settlement cones on the trees. One of at least a half dozen storm slab avalanches that occurred in this area on March 22. Snowpit tests in the crown indicated that the weak layer was no longer reactive. Cracked settlement cone below treeline. Forecaster

Avalanche Observation 		Tamarack Peak
Mount Rose Area 		Viewing the avalanche on the far east ridge of Tamarack from the Proleteriat Debris pile at the base of the avalanche. Smaller cornice pieces dropped onto a wind-loaded test slope. These did not trigger any cracking or wind slab failures. Some skier triggered cracking on a wind-loaded test slope. Forecaster

Snowpack Observation 		Powderhouse Peak
Luther Pass Area (including Job and Freel) 		Most trees above 8200 feet showed significant signs of settlement. Above treeline the wind had compacted the new snow and made it very dense and slabby. Small cornices were impressively strong. No significant cracking or propagation observed. Wind affected snow below treeline (but nearing summit ridge). Professional Observer

Avalanche Observation 		Hidden Peak
West Shore Area 		Supportable crust 6,500' to 7,150'. Crust giving way to unconsolidated storm snow at 7,500'. Signs of 2 to 3 inches of storm snow settlement around trees. Natural avalalanche, very fresh looking. Likely triggered by cornince fall earlier this morning. 1 of 2 similar avalanches in this cliff area. Blowing snow on summit ridge. Intentional cornince collapse produced no results. Forecaster
