Analyzing Snow Stability and Avalanche Hazard
The AIARE 2 course is a 3-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 AIARE 2 course builds from the introductory avalanche hazard management model introduced in the Level 1 course and adds to it the evaluation of factors critical to stability evaluation. The AIARE 2 is a three-day course for those who have taken an AIARE 1 and Avalanche Rescue and have had at least a year of backcountry travel experience.
We will spend a few hours in the classroom on day 1 to cover some more academic material, while days 2 and 3 will be based entirely in the field.
Students will advance their understanding of avalanche terrain, particularly from the perspective of stability analysis. We will discuss how the snowpack develops and metamorphoses over time; and discuss the factors that contribute to spatial variability. We will learn standard observation guidelines and recording formats for factors that influence or indicate snow stability. Finally, we will introduce a snow stability analysis and forecasting framework that will help you work towards creating your own forecast during times when the local forecast is not issued. This is important in Central Oregon!
The 8-hour AIARE Avalanche Rescue Course is a prerequisite for AIARE 2. If you haven’t already taken the AIARE Avalanche Rescue Course, you can register for that course separately.
Students must have the ability to travel in avalanche terrain on skis or a splitboard. An AIARE Level 1 Course (strongly recommended). The 1 day AIARE Rescue Course is also required.
