OUR MISSION:

Empowering Colorado ice climbers to mitigate avalanche risk.

The Avalanche Terrain Exposure Scale is a system for analyzing and rating avalanche terrain, so that skiers, hikers, climbers and others can better understand their degree of avalanche exposure while in the backcountry.

We need you.

It takes money to do the ATES analysis and ratings. Our analysts need topo maps, avalanche path maps, photos and drone photos to rate the climbs. You can help us continue our work and add to the list of climbs with ATES ratings by donating today.
