Three Sisters Backcountry offers AIARE Avalanche Courses at Tam McArthur Rim outside Sisters, Oregon. With varied terrain, elevations and aspects, the avalanche conditions can range from simple to complex.

Our Level 1 and 2 courses are based out of our Tam Rim Alpine Yurts and offer a full immersion hut-based backcountry experience. This allows us more time to conduct our lessons out in the snow. Less Powerpoint, more time on skis. This is the best way to learn… and the most fun!

New this season we will be offering  a 1 day Avalanche Rescue Course.   This course will also be taught on skis in the terrain for more fun and realistic scenarios.

Course Standards:

Level 1 Avalanche Course

Hut Based Level 1

Level 1 courses are recommended for everyone who enjoys playing or recreating in avalanche terrain.

This course informs general users of potential backcountry hazards and builds the foundation for the aspiring professional.


Level 2 Avalanche Course

Hut Based Level 2

This course is designed for the avid recreational skier and/or the aspiring professional.   We offer a 4-day hut based program based out of our Yurts at Three Creeks Lake.

This is the core course for recreational group leaders and includes the introductory and prerequisite components for the professional progression: the Level III certificate.
