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 		Elephant's Hump
Carson Pass Area 		10:45 am: Deep ski penetration in to wet snow on sunny NE aspect terrain around 8,000'. 10 am: Deep boot penetration into wet snow at the trailhead. This open E aspect near treeline had much better supportability than the other slopes around it. Forecaster

Snowpack Observation 		Jakes Peak
West Shore Area 		Small wet loose avalanche triggered on a small convexity off of a ski turn on ENE aspect terrain at about 8,200'. Unsupportable, deep ski penetration at 11 am on ENE aspect at about 8,300. Deep boot penetration into wet snow a few minutes before 10 am in open area on a NE aspect at about 7,400'. Forecaster

Snowpack Observation 		Tallac
Desolation Wilderness Area (including Emerald Bay) 		South bowl zone on Tallac Minimal boot penetration at 10:30am on a low angle open area at 8000 feet. We encountered two different snow holes/moats. Skinning higher on this E facing slope the NE side had soft still transitioning new snow. Looking further east at the Crystal Range Small skier triggered wet loose slides. These were easy to trigger on the NE side of this run. The E side of this feature had quality corn with now wet loose issues. Lower on the mountain we found more widespread wet loose issues. Lower elevation and later in the day produced impressively deep boot penetration. Professional Observer

Snowpack Observation 		Mt Houghton
Mount Rose Area 		Skier triggered small wet loose avalanche on E aspect at 11:30am On open slopes, loss of supportability started around 11:15am. View of SE side of Mt Houghton Poor overnight refreeze in dense treed areas Forecaster

Snowpack Observation 		Silver Peak
Cabin Creek, Deep Creek, or Pole Creek Area 		Small skier trigger wet loose activity on SE aspect at 11:30am SE aspect at 11:30am. Very light wind scouring along ridges from previous NE winds. Small roller balls on N aspect around 7600'. Forecaster

Snowpack Observation 		Rubicon Peak
West Shore Area 		Trace amounts of new snow at 6,800' New snow amounts increased to 3-4 inches above 8500 ft. Some minor cracking in a drift of snow created by the NE winds near the summit of Rubicon. Riming on the NE facing side of the trees along the summit ridge of Rubicon indicating NE winds. While blowing snow was only moderate today, there was enough to partly fill in this skin track during our tour. Another section of skin track filled in with blowing snow from today. Plumes of blowing snow along the high peaks in Desolation Wilderness. Public

Snowpack Observation 		Powderhouse
Luther Pass Area (including Job and Freel) 		About an inch of snow sitting on soft saturated snow at the 7400 foot trailhead Looking up at the partially clearing sky and snow speckled to the north side of the trees At around 8500 feet snow depth was about 4 inches of new. None of the ridge features I visited held wind slab. Professional Observer

Snowpack Observation 		Lincoln Ridge
Yuba Pass Area 		Small cornices cracked easily above wind-loaded slopes. Near the ridgeline this developing wind slab measured about 6 inches deep. A few feet down the slope the wind slab had diminished to about 3 inches in depth. Intense blowing snow on along Lincoln Ridge. The depth of wind-loaded snow tapered off quickly as one moved away from the ridge. Snow showers mixed with periods of lighter precipitation and sun peeking through the clouds occurred during our tour. About 1 inch of new snow at the trailhead at 11:30 am. 2-3 inches of new snow accumulation at about 7400 ft around 1:00 pm. Forecaster

Snowpack Observation 		Mt. Tallac
Desolation Wilderness Area (including Emerald Bay) 		Small sluff of wet snow on an E aspect at 9000 ft around noon. Supportable crust on N aspects below 8000 ft. Above 8000 ft the crust was only semi-supportable. Wind sculpted surfaces on exposed N and NE aspects at the upper elevations. Thin high clouds did not hinder today's warming. Shallow wet snow on top of a thin refrozen crust on top of a few more inches of wet snow on an E aspect at 9100 ft. Forecaster

Snowpack Observation 		Tamarack Peak
Mount Rose Area 		10:45 am cloud cover. Pano looking S-W-N from South Lake Tahoe to Mount Rose. 1 cm of new snow from Tuesday in the area. Semi-supportable to supportable crust on Tamarack Peak. Semi-supportable to supportable crust on Tamarack Peak. Forecaster
