      Abstract: This paper uses mobile phone data (Call Detail Record) to analyze backcountry skiers’ dynamics in avalanche terrain. A case study is conducted in Andorra using data from February 2018. In this study, mobile phone data is combined with the Avalanche Terrain Exposure Scale (ATES) cartography to analyze the behavior of people in ATES zones. The analysis is delimited in Sorteny valley, in Ordino (Andorra), a popular zone with a large number of backcountry routes, and includes different episodes based on the avalanche danger level and meteorological conditions of specific days. Previous results quantify changes in terms of terrain selection of skiers in different avalanche danger conditions. This case study shows the value of mobile phone data to explore people behavior in mountainous areas and identifies some limitations in terms of data accuracy.
