Hut Based Level 1: Decision Making in Avalanche Terrain

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:

All courses are FULL for the 2016/17 season.

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.

  • 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.”
  • Give lessons and exercises that are practically oriented, useful, and applicable in the field.
  • You must have the ability to travel in winter backcountry terrain.
  • Telemark, Alpine Touring Skis or Split Snowboard with skins are the preferred equipment.

We provide topo maps at the Huts for you to plan your daily adventures.
