Avalanche Level 1 (AIARE) - Decision Making in Avalanche Terrain - Portland

Winter, Adventure

Description: The AIARE Avalanche Level 1 class is a 4 day/24 hour introduction (including both class and field instruction) to avalanche hazard management. The course is expected to: provide a basic understanding of avalanches; describe a framework for decision making and risk management in avalanche terrain; focus on identifying the right questions, rather than on providing "answers"; and, give lessons and exercises that are practically oriented, useful, and applicable in the field. Students can expect to develop a good grounding in how to prepare for and carry out a trip; to understand basic decision making while in the field; and, to learn rescue techniques required to find and dig up a buried individual (if an avalanche occurs and someone in the party is caught). This course is taught by Timberline Mountain Guides in partnership with REI. Student Prerequisites: students must be able to travel in avalanche terrain. Classroom sessions will take place at the Portland REI from 6 pm - 9 pm on Tuesday 1/21 & Thursday 1/23. Two full-day field sessions will take place on Mt. Hood Saturday 1/25 & Sunday 1/26 (exact locations TBD based on currrent conditions).
