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 http://www.snowpilot.org/. This website also has a quick video and user guide on how to use create snowpits.

This slide was triggered from this spot on the ridge above the slide. The lower angle slope below me cracked but did not slide.
Overview of the slide, taken from between the trigger point and the crown.
Looking a the skiers left side of the crown from the middle of the avalanche. Note the firm bed surface (the 12/15 rain crust) and the thin darker line in the crown just above the rain crust at the bottom of the new snow - the near crust facets.
Skier's right side of the crown and flank as the slope become lower angle to the skier's right.
Looking down the path at the debris and terrain traps below.
Small skier triggered loose dry sluff and a shooting crack on a N-NE facing slope around 8000 ft.
