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.

03/05/2022 - 12:00 Silver Peak Cabin Creek, Deep Creek, or Pole Creek Area Snowpack Observation A ski kick caused the small wind slab to fracture on a NNE slope at ~7300 ft. Some light wind scouring as the winds shifted to the W along the upper ridge of Silver Peak. Cracking in a shallow wind slab above previous ski track. Ski cuts on this below treeline slope only pushed the loose new snow down the slope. Forecaster

03/05/2022 - 11:00 Hidden Peak West Shore Area Snowpack Observation Most of the day had more clouds than this but occasional pockets of blue did emerge. Surprisingly little evidence of wind slab were observed. This was the most cohesive new snow I could find on the summit area. Looking north towards Rubicon Peak. Trees on the summit ridge had soft snow sticking to their branches. On a steeper rollover at about 8000 feet there was some sluffing. I heard reports of larger stuffs running longer on more east facing terrain with a firmer crust. Professional Observer

03/04/2022 - 11:00 Chickadee Ridge Mount Rose Area Snowpack Observation Less than an inch of new snow had accumulated on Chickadee Ridge by 11 am. Periods of low clouds obscured visibility. Shallowly buried facets still existed below the surface on N aspects, but we did not see any signs of instability associated with them. The south aspects of Slide Mtn. are mostly melted out to bare ground. Forecaster
03/03/2022 - 11:00 Jakes Peak West Shore Area Snowpack Observation Increasing cloud cover ahead of tonight's storm. Not enough to slow snow surface melt. Skier triggered rollerballs and pinwheels in E to NE aspect terrain Skier triggered pinwheel almost 2 feet in diameter. Forecaster

03/02/2022 - 11:00 Rose Knob Peak Mount Rose Area Snowpack Observation Tiny wet loose avalanche intentionally triggered by ski cut on micro NE aspect of greater E aspect terrain at around 8,600'. Roller balls and pinwheels intentionally triggered on E aspect terrain around 8,200' Impressive section of fractured and collapsed cornices. Dwindling snowcover below 7,800' on SE aspect terrain. Increasing cloud cover over Lake Tahoe ahead of the slowly approaching storm system for tomorrow night. Forecaster
