OEAC 2400 Avalanche Level 2

The Avalanche Level 2 course provides backcountry leaders the opportunity to advance their avalanche knowledge and decision making skills. The Level 2 builds from the introductory avalanche hazard management model introduced in the Level 1 course, and adds the evaluation of factors critical to snow stability analysis. Students will spend a mix of their time in a classroom and outdoors in the snow. This course is taught in partnership with the American Institute for Avalanche Research and Education (AIARE) and successful students will receive a certificate of completion for the AIARE Level 2 Avalanche Training. Prerequisites: OEAC 1400 Avalanche Level 1. (1 lect, 2 lab.)

10. Information gathering--Site selection and relevancy, Spatial variability, and Slope tests

11. Companion Rescue--Multiple burials and shovel techniques

Outcomes

In order to successfully complete this course, the student will:

1. Advanced knowledge of avalanche terrain, particularly from the perspective of stability analysis.

2. Discuss how the snowpack develops and metamorphoses over time; and discuss the factors that contribute to spatial variability.

3. Describe standard observation guidelines and recording formats for factors that influence or indicate snow stability.

4. Analyze avalanche release and triggering mechanisms.

5. Perform a snow stability analysis and forecasting framework.

6. Demonstrate companion rescue skills including multiple and deep burials.
