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
