AIARE Avalanche Level 1

AIARE Avalanche Level 2
Analyzing Snow Stability and Avalanche Hazard     2 Day

The AIARE 2 is a two-day course with 2 full field days and 8 hours of online course work ahead of time. It   provides backcountry travelers an opportunity to advance their decision making skills in more complicated situations such as being a leader within a small travel group, traveling in more complicated terrain, and/or developing a travel plan where online resources are scarce. The AIARE 2 builds on the introductory avalanche hazard management model introduced in the AIARE 1 and adds to it the evaluation of critical hazard assessment factors. Students will describe and discuss weather, snowpack and avalanche processes, and identify how these processes relate to observations and travel within avalanche terrain. required materials.

Cost: $595
