  • Canada West Mountain School has been offering avalanche skills training courses since 1982 - our 2022/23 season AST-1 Classic is built on more than 40 years of experience conducting Avalanche Skills safety training to the highest standard possible. For the 2022-23 season, we have incorporated an enhanced online learning module through our Virtual Classroom, allowing for greater flexibility and improved learning options.

    The Seymour AST-1 Classic course focuses on teaching practical methods of understanding, recognizing and avoiding avalanche hazards, including terrain evaluation, effective decision making, group management, safe route finding, snowpack structure, weather, and avalanche rescue techniques.

      The AST-1 format includes:
    • 7 hours of theory, split between Virtual Online learning and in-person sessions
    • 2 days of training combining outdoor practice, and on-snow field work in the backcountry

      2 Manuals are included in the course and are an integral part of the course content:
    • the "Avalanche Skills Training Handbook"
    • the "Avaluator V.2" decision making guide"

    Our AST-1 course content and materials have been developed and refined over the past 40 years and are based on the nationally-recognized AST-1 curriculum developed by Avalanche Canada.

    Theory topics include:
    • avalanche hazard recognition
    • avalanche terminology
    • decision making and human factors
    • avalanche mechanics
    • mountain weather
    • snowpack structure
    • basic terrain evaluation
    • equipment requirements
    • introduction to Avalanche Companion Rescue

    The initial theory sessions also will prepare you for the practical field sessions, to ensure that your time in the field is used most efficiently.

    Skills and topics covered on the practical field training include:
    • terrain evaluation
    • mountain hazard assessment
    • group management
    • effective decision making in Avalanche Terrain
    • safe route finding techniques
    • snowpack analysis
    • snow testing techniques
    • transceiver searches
    • rescue fundamentals

  • Day-1 Practical Training will be held in an outdoor location in North or West Vancouver. Day-2 practical on-snow field sessions for the AST-1 course will be held in the backcountry behind Mount Seymour unless otherwise noted. Occasionally, alternate locations may be used such as Whistler/Blackcomb if conditions are not suitable. The field session logistics and details will be discussed during the class theory sessions.

    In the event that snowpack and/or weather conditions are such that we cannot conduct a good quality field session on the date for your course on Mt Seymour, or any other North Shore location, the on-snow field sessions may be postponed; or, held at Whistler/Blackcomb in the backcountry. This will require a lift access pass on Whistler/Blackcomb that is not included in the course fee. All other aspects of the course will remain unchanged.

    The decision to move the field sessions may not be made until 1-2 days in advance of the course, in order to assess the most current and updated snowpack and weather conditions.

  • Virtual classroom
    Before your AST-1 course dates, you will complete the self-paced online AST theory materials in our Virtual Classroom. This portion of the AST-1 course helps you develop the foundation of Avalanche Safety skills needed for the 2 field days.

    The Online Course in our Virtual Classroom requires about 3 hours of your time prior to the 2-day course dates. Our Virtual Classes are set up to deliver the content in an engaging and interactive style and are delivered through a series of Online Virtual lessons in advance of the in-person classes and practical field sessions.

    Course planning details and logistics are also found in the Virtual Classroom as well. The course planning and logistics details will be covered by online segments, email, and phone as needed.

    You will receive instructions on how to register and access the Virtual Classroom online course content after you have registered for your AST course.

    Practical Training
    The first day is an in-person training day combining interactive and engaging class sessions with an emphasis on group activities; and, practical outdoor training sessions. The Day-1 training is held at one of our training locations in Vancouver, West Vancouver, or North Vancouver. Start times for Day-1 vary between course dates but typically start as early as 7:30 am and finish by 4:30 pm. Specific locations and meeting times will be sent out in advance of each course date.

      The Day-1 session will focus on the following:
    • Team and Instructor Introductions
    • Trip planning
    • Terrain assessment
    • Decision making in Avalanche terrain
    • Interpretation and application of Avalanche Bulletins
    • Avalanche safety gear training and familiarization
    • Avalanche Rescue introduction and transceiver practice
    • Pre-trip planning and logistics for Day-2

    Day-1 is not an on-snow session, so skis, split boards or snowshoes are not required for the first day.

    The On-Snow practical field session will be held at Mount Seymour. The surge in numbers of visitors to Mount Seymour Park has led to severe parking and crowding issues. As a result, we are running our AST practical field session in a manner that helps reduce the impacts on the Park and some course dates may require using a shuttle bus service to access the backcountry course area. Final details are arranged during the week prior to each AST-1 date.

    The practical training sessions are held during a full day of "hands-on" practical learning in the field working on snowpack, terrain, travel, and rescue skills. This on-snow practical field day will take place fully in the backcountry regions of Mount Seymour Provincial Park. All students must be fully prepared for a day of backcountry touring on skis or split boards (or snowshoes, on snowshoe-based AST courses). The Day-2 field session starts with a 6:30 am meeting and typically is finished by 4:30 pm.

    The specific meeting locations and logistics details may vary from one course date to another, please ensure you confirm the correct location for your course date!

    Students are responsible for getting to and from the course meeting location on the North Shore at the base of Mount Seymour. During the class sessions in advance of the field training, you will discuss and plan the logistics for the specific meeting points and times for the Practical Field session of your course, though typically the field session will start with a 6:30 am meeting at the base of the Mount Seymour Road

    Students are reminded to plan to arrive 10-15 minutes early to all course sessions, to allow for traffic delays, poor road conditions, parking, etc. The Practical Field sessions will start promptly at the times indicated - latecomers will risk missing the field sessions as once the group has departed there are no options to join them in the field at a later time.
