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.

Donner Summit Area 		Storm slab, intentionally skier triggered, BTL terrain around 7,800' Storm slab, intentionally skier triggered, BTL terrain around 7,800' Storm slab cracking while breaking trail in wind protected BTL terrain. Moving above the skin track so that the storm slab was undercut made it easy to identify the layering. Shooting crack Forecaster

Carson Pass Area 		Repeatable ECTP results near the wind loaded ridgeline of The Nipple Three settlement cracks on the same tree A thick layer of wet snow 3ft below the surface, where grains were still loose and not bonding to each other 3ft of new snow above a thick rain layer. My probe is 10ft long, at the bottom of a 3ft hole, and still not touching the ground Professional Observer

Avalanche Observation 		Incline Peak
Mount Rose Area 		We intentionally triggered two wind slab avalanches on small NE aspect slopes in near treeline terrain. Both were 6 inch slabs of 4F+ over F hard snow. Cornices were weak, with sections up to 20 feet wide easily collapsed intentionally. Low cloud ceiling. Ongoing rapid settlement of storm snow. Forecaster

Snowpack Observation 		Rubicon Peak
West Shore Area 		Snowpit test targeting the storm snow did not produce signs of instability (ECTN). Runnels in thh snow surface indicating water draining through the snowpack at 6500 ft. Roller balls and pinwheels comprised of wet snow on a steep slope at 6850 feet. Ice on trees and a rain crust at the base of the storm snow existed all the way to the top of Rubicon. Small cracks in a wind-loaded area near the summit of Rubicon. Clouds and blowing snow at the summit of Rubicon made for poor visibility. Forecaster

Snowpack Observation 		Tamarack Peak
Mount Rose Area 		Dense snow supported us and kept us from sinking deeply into the storm snow. Snowboard kicks on wind loaded test slopes triggered cracking. A snowboard kick caused the small cornice above this test slope to fail and when it hit the slope below it triggered this wind slab. Tirggering wind slabs on small test slope was easy to do with a kick from a ski or by dropping a small piece of cornice onto the slope. New snow and blowing snow obsurced visibility and made it difficult to see into larger terrain. We gave the larger a terrain a wide berth to make sure we did not accidentaly stray into, below, or near avalanche terrain. Public

Avalanche Observation 		Andesite Ridge Looking up at an avalanche that likely happened last night. The debris looked like it had been wet. The filled in crown of the avalanche that had wet snow in it. One side of the crown of the avalanche triggered by the cornice pieces falling on the slope. Looking down on the debris and crown from the avalanche I remotely triggered when I stepped off my skis near the top of Andesite. When I stepped out of my skis on the ridge and broke through the rain crust, a cornice failed about 20-30 ft away and triggered another avalanche on a slope that had previously avalanched. Another mostly filled in avalanche midway up Andesite. The rain crust was thick, firm, and slippery near the top of Andesite Peak. At lower elevations it had not refrozen quite as much. About a foot of wet snow exited below the surface. Ice covered trees and rocks indicated that it rained at least to the summit of Andesite. Forecaster
