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 		Red Lake Peak
Carson Pass Area 		Red Lake cirque and non-frozen lake. Pit profile @ 8800' on N aspect. Ice crust at bottom of snow pack. Widespread riming event above ~9000. Small cornice release. Hand pit on 3-4" wind slab that released pretty easy but not planar. Professional Observer

Snowpack Observation 		Lincoln Ridge
Yuba Pass Area 		Surface hoar formed during the cold, calm clear night in most open areas. Cracks around the base of trees indicating snowpack settlement since the storm Wind scoured surfaces existed along the ridges. ECTN on a 30°, north-facing, wind-loaded slope. The wind slab did not show signs of instabilty. Oven-sized cornice pieces dropped on a wind-loaded slope did not produce any signs of instability. Lots of bushes and other obstacles still exist.
