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 		Lincoln Ridge
Yuba Pass Area 		Upper snowpack in wind protected below treeline areas Wind drifted snow up to 1' deep on SW side of ridge from strong NE winds this morning. Northerly aspect with up to 1' of wind blown snow with some NE wind protection. Strong NE winds had already scoured exposed northerly aspects back down to previous crusts.
