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. FAC 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. This program is available as a free download at http://www.snowpilot.org/. A video on how to download and use this program is available here.

Observations are a snapshot of a single point in space and time and subject to constantly evolving and spatially variable conditions. The Flathead Avalanche Center (FAC) cannot vouch for the quality or accuracy of any observations that come from the general public. Please use this page as part of your information gathering process, but don't make decisions based on a single piece of information.

The information on this page is consistent with the curriculum for avalanche classes and observational guidelines in the U.S. For more information about avalanche classes, visit the American Avalanche Association (AAA) or American Institute for Avalanche Research and Education (AIARE) websites.
