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 		Mt. Judah
Donner Summit Area 		Looking uphill from where I dug down to check melt layer depth. Top 50 cm of the HS 130cm snowpack on this S aspect at 7,600' has undergone repeated melt freeze. Forecaster

Snowpack Observation 		Powderhouse peak
Luther Pass Area (including Job and Freel) 		Large pocket of surface hoar on edge of grass lake. Large surface hoar grains in isolated area. Debris and needles across most aspects. 6-10" of near surface facets found in some areas. No signs of solar instability shedding off rocks throughout the day. Thin weakening crust between layers of near surface facets. Professional Observer

Snowpack Observation 		Lincoln Ridge
Yuba Pass Area 		Pit location on the edge of a below treeline avalanche path that receives full shade all day this time of year. 1 to 2 inches of surface wet snow on a SSW aspect slope a little below 7,800' at noon. Forecaster

Snowpack Observation 		Deep Creek
Cabin Creek, Deep Creek, or Pole Creek Area 		Large surface hoar existed in a few spots near the creek. It was not as big away from the creek and it will likely go through several cycles of destruction and regrowth before any new snow accumulates. ECTX on a N facing slope @ ~7800 ft. An old crack in the snowpack likely from early January. An old crack in the snowpack. This slope likely cracked in early January. The thin rain crust near the surface at 7800 ft. A thicker crust on the surface at a lower elevation. Forecaster

Snowpack Observation 		Red Lake Peak
Carson Pass Area 		The east facing side of the SE gully. Ample snow in the middle of the gully but sides are melting out. Some wintery snow in the flat terrain close to Red Lake Peak. Minimal boot penetration at 11:45am. Looking up towards the top of Red Lake Peak. Looking down the gully. Professional Observer

Snowpack Observation 		Silver Peak West
Cabin Creek, Deep Creek, or Pole Creek Area 		The NE winds have exposed the thin breakable rain crust. A thin layer of soft facetted snow existed below the breakable rain crust. A shallow hand pit showing the thin weak snow/crust/weak snow sandwich on top of stronger more consolidated snow. Surface hoar on a shady N aspect. Lots of debris has accumulated on the snow surface in some tree covered areas. The solid refreeze had just barely started to soften on southerly aspects by 9:30 am. Low clouds on Lake Tahoe indicating the inversion level. Forecaster

Snowpack Observation 		Mt. Judah
Donner Summit Area 		Weak snow/Crust/Weak Snow Sandwich on a N aspect on Mt. Judah. The winds were howling along the Judah ridgeline with gusts that could cause me to stumble. Firm, uneven, wind scoured surfaces existed in open areas. Firm refrozen melt-freeze snow existed on sunny aspects. Forecaster

Snowpack Observation 		Elephant's Hump
Carson Pass Area 		Upper snowpack structure on NE aspect at 8,400' in below treeline terrain. Surface facets providing for soft turns with minor loose dry sluffing. Potential corn lines holding on E-SE-S aspects of Red Lake Peak. S to SW aspects void of snow in many areas. Forecaster
