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.

Avalanche Observation 		Andesite Peak
Donner Summit Area 		One of the skier triggered wind slabs near the top of Andesite Peak Small wind slab failure on a test slope. A second ski kick at the spot just after the photo was taken triggered a large whumpf. Skier triggered D1 wind slab avalanche on NE aspect at 8000'. 50' wide x 70' long. Another small D1 skier triggered avalanche in similar terrain. Cracking started at the trailhead 8 inches of new snow acculumated at the trailhead while we were out. My pole is pushed into the level of our skin track when we started the day. Forecaster
