Registration is open for 2016/2017 season!

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

We have moved away from the standard 8-hour a day courses to exclusively 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!

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.

Level II provides backcountry leaders the opportunity to advance their avalanche knowledge and decision making skills.

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