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 		Snowpit location with 50cm snow depth, some previous wind loading.Snowcover of about 14 inches at about 7,350'FS Rd 12 at 6,900'. Rd plowed for logging operations. 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

Avalanche Observation 		Lincoln Ridge
Yuba Pass Area 		D1 natural wind slab avalanche, near treeline, NE aspect terrain at about 7,500'. Rain crust and Dec 1 PWL, obvious in the pit wall. Cornices building out in near treeline terrain. Cornices were weak and collapsed easily. Forecaster

Snowpack Observation 		Yuba Pass
Yuba Pass Area 		Cracking around skis while breaking trail. The longest cracks were 4 feet long. Large 25-30 mm SH under a surface slab. Jan 29 SH layer down about 12 cm PST 18/100 SF on Jan 29 SH layer, 4F hard slab over 25-30mm SH. 10 cm artificial slab added to the snow surface We left the artificial slab to sinter while we went and made other obs. When we returned to test the sample, someone had found it and their curiosity had lead them to damage it. Forecaster

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 		Surface hoar formed during the cold, calm clear night in most open areas. Cracks around the base of trees indicating snowpack settlement since the storm Wind scoured surfaces existed along the ridges. ECTN on a 30°, north-facing, wind-loaded slope. The wind slab did not show signs of instabilty. Oven-sized cornice pieces dropped on a wind-loaded slope did not produce any signs of instability. Lots of bushes and other obstacles still exist.
