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 		Waterhouse Peak
Luther Pass Area (including Job and Freel) 		5 inches of new snow in a wind protected open area off the edge of Grass Lake. High sun angle getting well into low to moderate slope angle N aspect terrain. As we approached treeline, our tracks in the new snow became more shallow with NE wind scouring.

Avalanche Observation 		Webber Peak
Little Truckee Summit Areas 		Shooting crack. Fracture depth ~60cm to our most recent rain layer. We experienced consistent cracking on F+ over F hard upside down storm snow. Wind slab test slope triggered by ski kick. Another view of test slope wind slab failure. Red arrow indicates the far edge of avx in the previous image which sympathetically triggered the wind slab in the foreground. Strong to gale force winds transporting snow. Perazzo Meadows overlook. Deep snow and lots of wind evidence. Public
