Abstract: Parks Canada created the popular Avalanche Terrain Exposure Scale (ATES), identifying eleven factors that can increase the probability of an avalanche happening on a given slope. It creates an easy-to-use scale of exposure ratings for an area. Geographical Information Systems (GIS) has been used previously to produce a more technical analysis of avalanche terrain factors. Using ATES and GIS models, two maps were created of Hatch Peak at Hatcher Pass, Alaska. Hatch Peak was selected as a study area due to the large number of accidents. The first map, created using ArcGIS 10, shows potential release areas in regards to slope shape and angle analysis. The second map, created using Google Earth, shows the ATES analysis of the study site. When actual accident fatality data was overlaid on both maps, fatalities had occurred in areas identified by the model as high exposure and located below potential release areas.
