Please remember that these observations indicate what was going on in the snowpack at a single point in time and space. They may not represent conditions where you are or where you plan to be. They also come from a variety of sources. SAC cannot vouch for the quality or accuracy of any observations that come from the general public. Some of these may be professional quality observations; some may not. Please use observations listed on this page as part of your information gathering process, but as always don't make decisions based on a single piece of information. If you are looking for more information on how to understand the information on this page, all of the pit data graphs and stability tests are part of what is presented in a Level II avalanche class that follows the American Avalanche Association (AAA) or American Institute for Avalanche Research and Education (AIARE) curriculum guidelines. All of the coding and abbreviations for data presented follows the publication Snow, Weather, and Avalanches: Observational Guidelines for Avalanche Programs in the United States (SWAG) which is the standard for all professional avalanche programs in the US. An electronic copy is available here. Most of what you are looking for is in Chapter 2 and Appendix F part 1. We use a program called SnowPilot to create the snowpit graphs. It is available as an online tool or as a downloadable program at This website also has a quick video and user guide on how to use create snowpits.

03/02/2019 - 11:15 Jakes Peak West Shore Area Avalanche Observation First avalanche triggered at ~8,700' by intentional ski cut. Moving below 7,800' these avalanches could be triggered by ski cuts on just about any convexity about 34 degrees and steeper. At around 7000', this storm slab/loose wet hybrid triggered by ski cut. Avalanche debris into trees below. Forecaster

03/03/2019 - 11:00 Incline Lake Peak Mount Rose Area Avalanche Observation 6 inch wind slab failure on test slope triggered by intentional cornice colapse. Same 6 inch wind slab failure on test slope. Dryish loose wet avalanche intentionally triggered by ski cut on 38 degree N aspect slope below treeline at ~9,200'. At 9,200', wind protected N aspect, below treeline open area, 20cm storm snow. Top 70 cm all right side up. ECTN results on upper 70cm of the snowpack. HS>3.7m Forecaster

03/04/2019 - 02:00 South Face of Slide Mountain Mount Rose Area Snowpack Observation Ski cut Public
03/04/2019 - 09:30 Carson Pass south Carson Pass Area Avalanche Observation A few inches of soft snow, then a breakable crust, then more soft snow. Small chunk of cornice broke but didn't propagate on slope below. In some areas breakable crust and collapsing soft snow around it created a sinking "snowshoe" effect while skinning. There were multiple similar avalanches that occurred yesterday along this ridge. This is one of the larger ones. Backlit cross section of snow adjacent to avalanche crown. Professional Observer
