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 		Winnemucca Lake
Carson Pass Area 		Note the contrast between steep slopes with a rough texture and steep slopes that are smooth Rough snow in the foreground and smooth, firm snow in the background Where I broke through the sastrugi, I checked under the firm snow to find small facets underneath Small, angular, and weak facets under the wind packed snow Professional Observer

Snowpack Observation 		Stevens Peak
Carson Pass Area 		A shovel tilt test showing buried surface hoar at the right depth to be the failure layer of a nearby previous avalanche. Further testing showed it to be unreactive A previous avalanche on a NE aspect at 8800ft. Zoom in to crown and it's not very weather worn During the calm morning, surface hoar growing where E winds recently blew Professional Observer

Snowpack Observation 		Stoney Ridge
West Shore Area 		Wind scouring near 8000' in open BTL terrain. Previous wind transport on Sun/Mon filling up this old skin track. ECTP-24 on hard wind slab Sun crusts forming on southerly aspects. Much calmer conditions today than recently with no blowing snow over upper elevations. Forecaster

Snowpack Observation 		Soft cold conditions near Saxon Creek.
Luther Pass Area (including Job and Freel) 		Wind effected snow on exposed areas near treeline. Thinner breakable windslabs on East aspects up to 9000'. Scattered debris from recent winds in lower elevations. Settlement cracks around trees at 9000'. Non-reactive compression tests on NW aspect @ 8700'. 300+cms @ 8700' on NW aspect. Planar results during hand shears on thin wind slabs. Professional Observer

Snowpack Observation 		Deep Creek Peak
Cabin Creek, Deep Creek, or Pole Creek Area 		We could see blowing snow along the ridges on the Sierra Crest. Winds affected snow was widespread on all aspects above treeline. Some wind affected snow existed in open areas below treeline Settlement cracks around trees indicating consolidation in the recent snow. 4-8 mm surface hoar was widespread on northerly aspects. Breakable sun crusts existed on the SE-S aspects Forecaster
