Avalanche Level 1 (AIARE): Decision Making In Avalanche Terrain

Description: The AIARE Avalanche Level 1 class is a 3 day/24 hour introduction (including both class and field instruction) to avalanche hazard management. 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 person (if an avalanche occurs and someone in the party is caught). A final debrief includes a knowledge quiz to test student comprehension and to give feedback to instructors on instructional tools. Students are encouraged and counseled on how to apply the skills learned and told that no course can fully guarantee safety, either during or after course completion. Student Prerequisites : Students must be able to travel in avalanche terrain. Classroom sessions take place at the Boulder REI from 5:00pm -8:45pm. Field sessions take place at Rocky Mountain National Park in Estes Park, CO from 8:15am-5:00pm.
