These observations document past conditions at a small and variable scale. They are not too 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 		Forestdale and Polaris Bowl
Carson Pass Area 		At lower elevations I could find buried surface hoar but ECTs did not propagate At 8700ft the wind slab was dense but ECTs did not propagate At 8800ft above Lost Lakes, both ECTs propagated, consistent with a recent avalanche This avalanche was not seen on Thursday. Trigger could be riders or cornice fall Professional Observer
