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 		Trimmer Peak
Luther Pass Area (including Job and Freel) 		We started to notice cracking and very localized collapsing of the ski track. A quick hand pit showed lower density, F hard snow below. ECTN results at this location where skin track cracking began. Snow surface cracking up to 4 feet long as we moved into near treeline terrain. ECTN results at this location where we triggered cracking in near treeline terrain. Plenty of snow still available for wind transport on the ridgetops and winds forecast to increase tonight.

Snowpack Observation 		Ophir Peak
Mount Rose Area 		Intense blowing snow along the ridge of Peak 9225. A ski kick caused a failure in the wind loaded snow on this small test slope. Ski kicks triggered long shooting cracks in wind-loaded areas. Snowdepth averaged 200-230cm in sheltered areas. A ski kick triggered a shooting crack that failed at the base of the storm snow on this wind loaded test slope. Skier triggered shooting crack that shot across the entire wind-loaded test slope.
