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

Avalanche Observation 		Mt. Judah
Donner Summit Area 		Several natural avalanches on Mt. Judah occurring at different times throughout the 1/5-1/7 storm cycle. Some avalanches ran full path to bottom flats. 8100', E aspect. Different angle of Mt. Judah avalanches. Some debris mostly covered and some looks to have occurred towards the end of the storm. Multiple natural wind slab avalanches on Wildflower Ridge, 7800', NE aspect. Forecaster

Snowpack Observation 		Hidden Peak
West Shore Area 		One of the many whumpfs we felt between 6900 and 8300 ft. This one propogated about 100 ft away from us in all directions and left small cracks like the one I am pointing at in the snow surface. Forecaster

Snowpack Observation 		Powderhouse Peak
Luther Pass Area (including Job and Freel) 		New storm slab cracking on slope undercut by skin track. Flipping my ski pole upside down, the snow was quite resistant initially in the firm storm slab. Once through the storm slab, the snow was very soft for the rest of the length of my ski pole. Tree rings demonstrating snow settlement due to warming. Hand hardness overview of new snow. One finger hard slab, over fist hard storm snow. Professional Observer

Snowpack Observation 		Incline Lake Peak
Mount Rose Area 		Kicking at the uphill side of the skin track yielded storm slab cracking at 8,400 feet. ECTN12 20cm down at the bottom of the dense storm slab. N aspect at 9,100 feet. CT8 at the same storm slab layer as the ECTN. This compression test also broke CT24 Q2 at the top of the crust sandwich layer in the old snow Public
