Snow Profiles for the 2009 / 2010 Season
Northwest Weather and Avalanche Center
These snowpits were prepared either by NWAC staff, program cooperators or other contributors in the area indicated. Warning: Use care and common sense when applying snowpit and stability test information, and consult other sources whenever possible. For example: consult the NWAC, ski area or highway department avalanche personnel during the winter or early spring, and talk with Forest Service or Park Service rangers during the later spring and summer. These observations provide an historical framework and general guideline to trends in snow pack stability. You are responsible for using and applying any information. Choice not Chance causes most avalanche accidents. Each snowpit shown is a snapshot of the snowpack structure at a certain time and a certain place. It is a fact that the snow pack is highly variable, very dynamic, and snow structure and related stability can and do change within a few feet and often within a few hours, sometimes dramatically. By emailing snowpits to the NWAC, we assume that we have your permission to post them unless indicated otherwise. Please e-mail snowpits to forecasters@nwac.us
