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.

03/13/2019 - 13:00 Elephants Hump Carson Pass Area Snowpack Observation Scoured NE facing slope near the ridgeline Ice crust exposed by wind scouring on the ridge NE wind transport off of Red Lake Peak ECTN on a previously wind-loaded NE facing test slope. Forecaster
12/19/2018 - 11:30 Ellis Peak Blackwood Canyon or Ward Canyon Area Avalanche Observation Intentionally triggered wind slab avalanche, D1. Another photo of same avalanche. Forecaster
01/19/2019 - 12:00 English Mountain Independence Lake Area Snowpack Observation Roller balls on the west side of Jackson Meadows Reservoir from rain on snow. Small crown from wet snow avalanche near noted lat/long. Another small crown from wet snow avalanche near noted lat/long. Fog and light rain on NE side of English Mtn. Forecaster
11/23/2018 - 12:30 Far East Ridge of Tamarack Peak Mount Rose Area Snowpack Observation Some skier triggered cracking on a small wind-loaded test slope Representative snow coverage in non-wind-loaded terrain. There were numerous exposed and barely covered rocks. Wind-loaded areas held more snow coverage, but the coverage decreased quickly below the ridges with many areas of bare ground still present. Numerous bushes, stumps, rocks, and other obstacles still exposed. Many areas of bare ground still remain due to a combination of wind-scouring and a lack of snow. Forecaster
03/10/2019 - 13:00 Fire Plug Mount Rose Area Snowpack Observation 2-3 foot cornices would collapse with a few kicks After undercutting, this wind lip did not crack or break when jumped on Public
02/25/2019 - 09:30 Fire Plug Mount Rose Area Snowpack Observation Kicking at the uphill side of the skin track yielded some small windslab failures Windslab from first photo. Isolated pockets of sun softened crust on SSE aspects at 10:30. Public

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.

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
