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 		Mt. Judah
Donner Summit Area 		Long shooting cracks on a cross-loaded N facing slope above the standard skin track. A small natural test slope failure that we found on a NW aspect at near the trailhead. The wind slab formed by the NE winds was about 4-6 inches deep at the lower elevation areas near the start of our tour. Higher on Judah it was closer to 12 inches thick. Long shooting cracks on a wind loaded test slope near the trailhead. This slope faced NNW. Blowing snow obscured visibility near the summit, but we could still see huge cornices above the E face of Mt. Judah. Large cornices above Wildflower Ridge. Scoured and sculpted snow surfaces existed on ridges and in open areas. Blowing snow quickly refilled the skin track near the summit of Judah. Forecaster

Avalanche Observation 		Castle Peak
Donner Summit Area 		D1 Wind slab failure on a wind-loaded test slope. Looking at the same test slope failure from the other side. The wind slab failed on a layer of softer storm snow. It was about 10 to 15 inches thick. Ski kicks on some wind-loaded test slope produced 15-20 ft long shooting cracks. Minor cracking in the storm snow on a small test slope sheltered from the wind. Intense blowing snow along the ridgelines. Some signs of settlement in the recent snow. Public

Snowpack Observation 		Genoa Peak
East Shore Area 		Freezing fog along the ridge top. Genoa Peak wasn't far in the background but not visible today Drifts from previous and current winds, which varied from N to E to W today A few stripes in my snowpit from the recent warm temps, but no faceting Professional Observer

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
