AIARE 2 Avalanche Course

Length:3 days
Price:$685 per person
Dates:February 14-16, 2024
Location:Three Sisters Wilderness, Central Oregon


The AIARE  2 course is a 3-day program that provides backcountry leaders the opportunity to advance their avalanche knowledge and decision making skills. This course also includes the introductory and prerequisite components for the professional progression.

The AIARE 2 course builds from the introductory avalanche hazard management model introduced in the Level 1 course and adds to it the evaluation of factors critical to stability evaluation. The AIARE 2 is a three-day course for those who have taken an AIARE 1 and Avalanche Rescue and have had at least a year of backcountry travel experience.

We will spend a few hours in the classroom on day 1 to cover some more academic material, while days 2 and 3 will be based entirely in the field.

Students will advance their understanding of avalanche terrain, particularly from the perspective of stability analysis. We will discuss how the snowpack develops and metamorphoses over time; and discuss the factors that contribute to spatial variability. We will learn standard observation guidelines and recording formats for factors that influence or indicate snow stability. Finally, we will introduce a snow stability analysis and forecasting framework that will help you work towards creating your own forecast during times when the local forecast is not issued. This is important in Central Oregon!

The 8-hour AIARE Avalanche Rescue Course is a prerequisite for AIARE 2. If you haven’t already taken the AIARE Avalanche Rescue Course, you can register for that course separately.


Students must have the ability to travel in avalanche terrain on skis or a splitboard. An AIARE Level 1 Course (strongly recommended). The 1 day AIARE Rescue Course is also required.

"I am very happy with my TMG experience. The guides were professional, personable, and extremely concerned about safety. . . I absolutely give highest marks to these guys. If you don't have much Alpine experience, or just want the security of seasoned veterans guiding you up this mountain, then I strongly recommend you sign up with them. Thanks, guys, for a great experience!!"

"What a fantastic experience gaining the summit of a mountain we've gazed on from Portland for 25 years! . . . We learned a great deal, had a ton of fun, felt in very capable hands, and had the reward of summiting on a beautiful clear day. The value of being with a professional, certified, guide and guiding organization was evident throughout. Kudos to the TMG team who were responsive, supportive, and fun to work with every step of the way."

"We booked 2-day overnight program on Mt. Hood with Timberline Mountain Guides. Our guides were great, . . super friendly and reputable. The program did not go as planned due to inclement weather but we still had fun and good experience. The guides were definitely flexible and provided guidance during the trip. I would recommend going with them if it's your first climbing trip on Mt. Hood for sure."
