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 		Castle Peak
Donner Summit Area 		1 to 2 ft deep wind slab failure triggered by ski kick on this test slope. Small wind slab and sluff on a wind-loaded test slope. The left side sluffed and entrained about 12-18 inches of new snow but did not propagate beyond my ski. The right side cracked and propagated anout 20 ft to the right but was only about 6 inches deep on that side. 6-8 inch deep wind slab on a wind loaded test slope. 6 inch deep crack triggered on another wind loaded test slope. Blowing snow and low visibility along the Castle/Basin Ridge A small storm slab on a test slope likely from yesterday. Forecaster

Snowpack Observation 		Silver Peak
Cabin Creek, Deep Creek, or Pole Creek Area 		Minor storm slab cracking noted on the approach. Failure on plate snow crystals within the lower portion of the new snow. Intentional wind pillow collapse at 11 am that had very little propagation, mostly just entertainment of new snow. A second intentional wind pillow collapse at 1 pm which triggered a small wind slab at the top of the recent new snow (same location as the 11 am collapse).. Thick cloud cover moving in at 11 am. Snow showers visible in the distance towards South Lake Tahoe. Forecaster
