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 		Move snow cover at 7,600' than we have seen in the rest of the forecast area. Facets from the Nov 9 layer starting to show striations. Surface hoar in excess of 1 cm that will likely be destroyed before burial. Forecaster

Snowpack Observation 		Relay Peak
Mount Rose Area 		Snowpit location on a N aspect at 9350 ft. Overall the snowpack is weak and getting weaker. Snow coverage is ok on N-E aspects above 9000 ft. SE-S aspects quickly turn to dirt. Weaker breakable crusts in the shady areas and stronger more supportable crusts in the sunny areas. SE aspects had little to no snow on them. Forecaster

Snowpack Observation 		Red Lake Peak
Carson Pass Area 		Professional Observer
11/30/2021 - 11:45
Snowpack Observation 		Mount Lola
Independence Lake Area 		Pit dug in foreground shadows. Good coverage 2-3 feet deep across the summit bowl. In the pit. Rain crust layers visible with potentially problematic facets in between. Looking SE off Lola the N vs S aspect snowcover distribution is well defined. Good coverage on N side of Castle/Basin Pks complex. Forecaster

Ebbetts Pass Area 		Professional Observer
11/29/2021 - 11:30
Snowpack Observation 		Castle Peak
Donner Summit Area 		Weak facets below surface rain crust on well shaded E aspect around 7,500'. Weak facets below surface rain crust on well shaded E aspect around 7,500'. F hard surface facets on top of rain crust, N aspect at around 8,200'. Foot punch through surface rain crust into facets on shaded WNW aspect at around 8,400'. Melted south aspects, snow covered north aspects. Forecaster

Snowpack Observation 		Elephants Back
Carson Pass Area 		Mixed trail of snow and dirt. Flowing drainages throughout the tour. Melt freeze crust on the surface. Pit profile Thinning snowpack looking towards Blue Lakes from Elephants Back Looking out towards Meiss Meadow. Professional Observer
11/24/2021 - 11:00
Snowpack Observation 		Tamarack Peak
Mount Rose Area 		Patchy snow cover existed on the north aspects below 9000 ft with dirt on other aspects. Snow coverage improved on northerly aspects at higher elevations. Forecaster

Snowpack Observation 		Silver Peak
Cabin Creek, Deep Creek, or Pole Creek Area 		surface crust w/bed of facets, superficial crust, facets XXX mark facets separating the crusts a slightly different location (still in the Norths) showing a thicker surface crust with about 6-8cm of sugar facets below with about Public

Snowpack Observation 		Kirkwood - Sentinel Bowl
Carson Pass Area 		Public
11/22/2021 - 12:00
Snowpack Observation 		Elephants Back Area
Carson Pass Area 		The surface rain crust in on a N aspect at ~8650 ft. It was thin and breakable in this area with weak snow below it. The layer of ice at the base of the snowpack. N Facing aspects on Round Top. We could see the glare of crusts on the surface as the sun reflected off them. The sun exposed southerly aspects on Red Lake Peak were bare ground. Forecaster

Snowpack Observation 		Noble canyon trailhead
Ebbetts Pass Area 		Public
11/19/2021 - 11:00
Snowpack Observation 		Tamarack Peak
Mount Rose Area 		The middle part of the snowpack continues to facet and weaken over time. Continuous snow coverage above 9000' on N and E aspects. Very minor cracking in a couple areas right off the ridge with up to 4'' of wind slab. Forecaster
11/16/2021 - 23:15
Snowpack Observation 		Rubicon Peak
West Shore Area 		Little to no snow cover on northerly aspects below 7,800'. Continuous snow cover at about 8,200' on northerly aspects. A 2 to 2.5 foot deep snowpack just below 9,000' on N aspect terrain. Artificial load of 15 cm slab on PST gave PST 28/100 end result on facets below surface crust. Looking south from near the summit of Rubicon shows snow covered northerly aspects. Looking north from near the summit of Rubicon Peak shows mostly bare ground on southerly aspects and lower elevation areas. Forecaster

Snowpack Observation 		Mt. Lola - NE Ridge
Independence Lake Area 		Patchy snowcover on the transition from NE to E aspects around 7,800' Supportable wet snow, corn like conditions on NNE aspects we traveled in the 7,800' to 8,500' elevation range. Looking across at the Mt. Lola summit bowl (8,800' to 9.000' N-NE-E aspects), snowcover appeared decent. Forecaster
