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
Charity Valley

Carson Pass Area
Old snow under the new was still quite soft and even with only 4-6" of new snow the riding was excellent Buried surface hoar An ECT with partial propagation, just lacking more of a slab Professional Observer

Snowpack Observation
Lincoln Ridge

Yuba Pass Area
Surface hoar buried under 10 to 12 inches of cold, soft, and light wind-blown snow near Lincoln Ridge. Buried surface hoar was easy to identify in hand pits. Ski kicks triggered some cracking in wind-blown areas and in sheltered areas where buried surface hoar existed. Small cornices built by NE winds on W and SW aspects. Small slab failure on a steep test slope. Loose dry sluff of new snow on top of surface hoar. Forecaster

Snowpack Observation
Winnemucca Lake

Carson Pass Area
Note the contrast between steep slopes with a rough texture and steep slopes that are smooth Rough snow in the foreground and smooth, firm snow in the background Where I broke through the sastrugi, I checked under the firm snow to find small facets underneath Small, angular, and weak facets under the wind packed snow Professional Observer

Snowpack Observation
Stevens Peak

Carson Pass Area
A shovel tilt test showing buried surface hoar at the right depth to be the failure layer of a nearby previous avalanche. Further testing showed it to be unreactive A previous avalanche on a NE aspect at 8800ft. Zoom in to crown and it's not very weather worn During the calm morning, surface hoar growing where E winds recently blew Professional Observer
