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.

03/20/2020 - 12:15 Powderhouse Peak Luther Pass Area (including Job and Freel) Snowpack Observation Transitional conditions in sun exposed areas. The presence of icicles and snow on the sunny side of this tree were both likely gone an hour after I took this photo. This open clearing surrounded by trees at 8300 feet did not have surface hoar present, but larger clearings just above it did. An open north west facing ridge just above 8400 feet had widespread surface hoar. The largest surface hoar I found was on the north side of a northwest ridge at 8800 feet. Professional Observer
