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.

02/19/2019 - 10:15 Flagpole Peak Echo Summit Area Snowpack Observation Sastrugi near ridgeline on Flagpole. Signs of settlement around trees Interesting evidence of previous avalanche activity. Interesting evidence of previous avalanche activity. The areas that slid were still soft, but less soft than areas that had not slid previously. Professional Observer
02/23/2019 - 11:30 Flagpole Peak Echo Summit Area Snowpack Observation Mid elevation wind effect. Impressive tree flagging from previous slide activity. Near the ridge evidence of previous E wind activity. Professional Observer
02/06/2019 - 10:00 Flagpole Peak Echo Summit Area Snowpack Observation Avalanche debris from a previous slide was buried under about a foot of soft snow. Minor wind effect observed at the saddle near the summit. Snow was still very soft. Some trees at the summit ridge still held snow despite previous wind and current direct sun. Tree wells were deep.
