Information provided here is one piece of the puzzle in effectively evaluating backcountry snow conditions and avalanche hazard. Weather, snow, and avalanche conditions are constantly changing and we are only able to provide small, static snapshots of this dynamic phenomena. In order to effectively use and apply the information found on this website you need to be educated and experienced in regard to avalanche safety, hazard recognition, and rescue. It is imperative that you receive avalanche education from a professional provider, carry all essential rescue equipment (beacon, shovel, and probe in addition to all tools and attire required for safe wintertime backcountry travel), and understand inherent risks before venturing into avalanche terrain. The Anchorage Avalanche Center (AAC) and its associates assume absolutely no liability or responsibility for the use of information provided on this website.
