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 		Hidden Peak
West Shore Area 		Minimal new snow on top of very rough melt-freeze/rain crust below 7,500'. Ski pole probe through 4 inches of surface crust into deep, not refrozen wet snow.Ski cuts on typically wind loaded test slopes along the summit ridge produced only small loose dry activity. Poor light, difficult to see shallow debris in photo. Forecaster

Snowpack Observation 		South Gullies
Mount Rose Area 		S aspects above 10k' did not soften due to gale force S winds at 11am. Small skier triggered loose wet activity within gully.Boot pen of 4-6'' at 8200', S aspect, at 11:30am. Forecaster

Snowpack Observation 		SE Gully on Waterhouse Peak
Luther Pass Area (including Job and Freel) 		At 8:30am, around 7200 feet on partially treed SE slope, the snow surface was soft and unfrozen.At 9:45am, around 8400 feet on an open SE slope, the snow surface was soft and a pole handle could easily penetrate about 20 cms.At 10:00am, around 9000 feet on open SE slope, the snow was cold and supportive due to consistent wind. A few trashcan size chunks of cornice appear to have broken off in the last day or two. Professional Observer
