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 		Fog conditions below 7,700'. Sunny skies above the inversion layer. Rimed surface snow and plenty of snow available on W aspects for future wind transport. Rimed surface snow. Rimed surface snow. Forecaster

Snowpack Observation 		Lincoln Ridge
Yuba Pass Area 		NE aspect wind scoured terrain at/just above treeline. Exposed rain crust on upper start zone, wind scoured mid slope, unconsolidated snow at treeline. Established tree well hazard if the forecasted 1-2+ feet of new snow verifies. Forecaster

Snowpack Observation 		Lincoln Ridge
Yuba Pass Area 		A weak sun crust had formed on the surface in sun-exposed areas. Ski kicks on wind-loaded test slopes did not produce wind slab failures only small sluffs of new snow. Large cornices still exist along Lincoln Ridge. Debris from old cornice collapses is visible on the slope below. The wind had exposed firm melt-freeze crusts on the ridges. Forecaster

Snowpack Observation 		Lincoln Ridge
Yuba Pass Area 		Wind scoured ridgetops with solar aspect melt to bare ground at 7,800'. Pit location on N aspect at 7,729. Well developed, dry and loose near surface facets from a hand pit. Good snowcover on the roads with loose cold snow for good machine cooling above 7,000'. Forecaster

Snowpack Observation 		Lincoln Ridge
Yuba Pass Area 		NE winds scouring cornices and drifting snow over the ridgetop. First signs of recent wind transport in textured surface upon reaching near treeline terrain. At 7,200', 8 inches of recent storm snow on top of 12/22 rain crust. No 12/24 rain crust present at and above 7,200'. ECTP-30 on 12/4 buried surface hoar layer. Forecaster

Snowpack Observation 		LIncoln Ridge
Yuba Pass Area 		Ski kicks triggered a small cornice failure above a N-facing wind-loaded test slope. ECTN on the facets below the recent snow. Surface hoar on wind protected slopes. Wind scoured areas along exposed ridges Wind scouring on a previously loaded NE facing slope. Clouds obscured the sun and slowed down warming during the morning. The sun broke through the clouds in this area around noon. Forecaster
