AVALANCHE TERRAIN EXPOSURE SCALE (ATES) HOW TO READ AND UNDERSTAND AVALANCHE CANADA’S TERRAIN RATINGS MAPS The Avalanche Terrain Exposure Scale (ATES) is a system of rating backcountry terrain by its potential to produce avalanches. It will help you know if the terrain in the area you’re planning to ride is Risk City or Chill-ville. While weather and snowpack stability are always changing, terrain is the constant factor in your calculations to minimize avalanche risk. The ability to evaluate terrain can help mitigate the influence of the two other variables, and help you stay safe in the backcountry.

THE TERRAIN DIRECTLY ABOVE BLUE LAKE IS RATED AS “COMPLEX”, MEANING IT HAS THE GREATEST POTENTIAL TO PRODUCE AVALANCHES.
