AIARE Level 2:
Analyzing Snow Stability and Avalanche Hazard
If are serious about learning more about avalanches and snowpack and have taken an AIARE Level 1 course, this is the course for you.
The Level 2 builds from the introductory avalanche hazard management model introduced in the level one and adds to it the evaluation of factors critical to stability evaluation.
The level 2 course is a 4-day program that provides backcountry leaders the opportunity to advance their avalanche knowledge and decision making skills.
This course also includes the introductory and prerequisite components for the professional progression: the level 3 certificate.
Student Learning Outcomes
Advance understanding of avalanche terrain, particularly from the perspective of stability analysis.
Discuss how the snowpack develops and metamorphoses over time; and discuss the factors that contribute to spatial variability.
Learn standard observation guidelines and recording formats for factors that influence or indicate snow stability. SWAG(Snow Weather and Avalanche Guidelines) MODULE.
Advance understanding of avalanche release and triggering mechanisms.
Introduce a snow stability analysis and forecasting framework.
Improve companion rescue skills including multiple and deep burials.
Instructional Sessions
(40 hours including both class and field) include:
Level 1 Review
Energy balance, the mountain snowpack and metamorphism
Faceting; near surface and near crust faceting
Formation of surface hoar and persistent weak layers
Skier Triggering: theory and observations
International and national snow, weather and avalanche observation and recording guidelines (SWAG).
- Weather; interpreting forecasts, recording and observation techniques
- Snow profile techniques and bonding tests
- Avalanche observations and recording techniques
Stability analysis checklist: reviewing critical factors
- Stability ratings
- Daily stability forecasts and analysis
Trip Planning and hazard forecasting for avalanche terrain.
- The avalanche danger ratings
- Terrain analysis using maps/photos
- Forecasting stability and variability
Terrain selection and route finding
- Group management and hazard management
- Decision making
- Human factors
Information gathering
- Site selection and relevancy
- Spatial variability
- Slope tests
Companion Rescue
- Level 1 techniques review
- Multiple burial
- Shovel techniques
Student Prerequisites: Students must have the ability to travel in avalanche terrain. Due to the nature of our terrain, ability to comfortably climb and/or ski frozen 40° slopes is required. An AIARE Level 1 Course (strongly recommended) or equivalent training/experience is required. A winter of practical experience after the Level 1 course is recommended before taking the Level 2 course.
Required equipment for all avalanche courses: Equipment List
Besides personal outdoor and ski equipment, the following items, available from AIARE, are required for Level 2:
AIARE Field Notebook
Snow Study Kit (Centimeter folding ruler, Celsius thermometer, crystal card (metal preferred), loupe)
