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. BAC 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 snowpit 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 two apps - SnowPilot and AvyLab - to create the snowpit graphs. These apps are available as downloads: click here for the free SnowPilot download; for AvyLab, visit Apple's AppStore or the AvyLab website
