  • The 2.5 day AST-1 PLUS Avalanche Skills course was pioneered by Canada West Mountain School in the 1980's and still proves to be the best combination of class theory and practical field training possible! This is our most comprehensive and popular AST-1 course.

    Our combination of using highly experienced CAA trained Instructors, two different days for field training and increased emphasis on technical snowpack and terrain observation and decision making skills ensures that you will be getting the best possible training available.

    The first classroom evening session is an engaging session of interactive learning, group sessions and multi-media presentations. Both of the field sessions emphasize "hands-on" practical learning in the field working on snowpack, terrain, travel and rescue skills. With 2 days of field training, ample time is available to practice core skills.

    Visit Guides and Instructors Page for complete details and background on each of our Guide Team.

  • The first evening class session will start at 6:30 PM. At this class session you will also receive instructions for the specific meeting points for the first field day of your course.

    There will be a practical field training session on Saturday from 8am to 4:30pm, followed by a wrap-up theory session on Saturday afternoon/evening, finishing around 6:30.

    Day-2 will be a full field session ending at 4:30 pm.

    This course focuses on teaching practical methods of understanding, recognizing and avoiding avalanche hazards, including terrain evaluation, snowpack structure, weather, safe route finding and avalanche rescue techniques.

    Our 2.5 day format includes 7 hours of theory and 12 hours of practical fieldwork. Manuals are included in the course and form an integral part of the learning. Our AST-1 course content and materials have been developed over the past 30 years and are based on the nationally-recognized AST-1 curriculum developed by Avalanche Canada.

    Theory topics include:

    • avalanche hazard recognition
    • terminology
    • avalanche mechanics
    • mountain weather
    • snowpack structure
    • basic terrain evaluation
    • equipment requirements

    The initial theory session also will prepare you for the field sessions so that your time in the field is used most efficiently.

    Your field days are spent in the backcountry where you will have maximum time to focus on learning and practicing skills, including:

    • terrain evaluation
    • mountain hazard assessment
    • safe route finding techniques
    • snowpack analysis
    • snow testing techniques
    • transceiver searches
    • rescue fundamentals

    The final wrap up sessions are an important aspect of Canada West Mountain School programs, as this allows students an opportunity to "put all the pieces together" in a classroom session after the field sessions have finished.

    At the end of your course, you are encouraged to discuss with your instructor the content that has been covered, and to have the instructor assess your level of knowledge - we would prefer that you know your abilities now, rather than find out the hard way, later!

  • Gear List - Canada West Mountain School Avalanche Course Gear List
