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
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

Small natural D1 wind slab avalanche on a SE aspect in NTL terrain. Small storm slab avalanches failing on convexities in BTL terrain. Loose dry sluffing off of Crag Peak Cracking around skis while breaking trail signaling storm slab instabilities.  Long shooting cracks off of ski tips while breaking trail. Looking out to Dicks Peak and Desolation Wilderness. Forecaster

Avalanche Observation
Tamarack Peak

Mount Rose Area
A couple small natural wind slab avalanches along the East Ridge of Tamarack peak. Small test slope failure with wind slab propagation 75' wide. Very large cornices exist off of ridges.  These could become an issue in the near future with warmer loading events. Intense blowing snow in the morning and midday. Investigating some weak NCF's around a melt freeze crust on S aspects, ECTN results. Forecaster

Some moments of blue sky during my time on Powerhouse. Settlement cones around trees. Near the summit ridge a large chunk of this cornice broke and travelled down the slope. Closer but off to the side of the same large cornice missing a chunk. Different cornice break and small wind slab. On a much smaller but nearby cornice I only got minimal cracking and propagation to ski kicks. Professional Observer
