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.

Mix of blue sky and clouds. The only signs of instability I encountered today was on this south facing steep roll. Lots of graupel near the faint crust below the recent storm snow. ECTN 16 down 40 cms I tried to create a thin wall of snow to look at the melt freeze crust and weak layer. Professional Observer
