This seminar requires no prerequisites. 

  1. Online day 3-4 hour classroom lecture where you will learn and review different avalanche terrain risks, and practice route finding through case studies. This must be completed before the field day on 1/11/26.
  2. Next is a 3 to 4 hour session in the field on January 11 2026.  In the field, the students will observe terrain and make travel decisions based on the planned route, and travel adjustments in the field in avoiding exposure to avalanche terrain. We'll use slope meters to identify potential avalanche terrain to avoid as we travel through non-avalanche terrain. These techniques can be taught with or without snow conditions.

Students should bring the regular 10 Essentials and be prepared for winter conditions in the field.

In order to AVOID avalanche terrain, you must be capable of RECOGNIZING IT.

This is the WHY - why you take ATA.

TBD on Grand Mesa Jan 11 2026.
