Abstract: It is difficult to rely on snow conditions, weather and human factors when making judgements about avalanche risk because these variables are dynamic and complex; terrain, however, is more easily observed and interpreted. Therefore, this study aimed to investigate 1) the type of terrain in which historical fatal snow avalanche accidents in Norway have occurred using the Avalanche Terrain Exposure Scale (ATES), and 2) how to implicate ATES in avalanche education. The ATES classifies terrain as simple (Class 1), challenging (Class 2) and complex (Class 3). We investigated 30 fatal slab avalanche accidents in Norway over a 10-year period (2005-2014) involving 42 deaths. According to the ATES, 77% of the accidents occurred in complex terrain and 23% occurred in challenging terrain. Our results indicate that the ATES is a practical tool that may help recreationists with trip planning in the type of terrain that suits their level of experience and knowledge. This tool can be valuable to novices by helping them to acquire experience in recognizing relevant terrain features that might compromise their safety and interfere with their plans. Results in this study shows that most avalanche accidents occurred in complex terrain. Thus, for novices and advanced beginners, learning to use the ATES provides a sound basis for safe travel and gaining experience in avalanche terrain.
