Abstract: In 1986, an avalanche mapping program began in the Catalan Pyrenees. Twenty years after, in 2006, the Avalanche Paths Map, a collection of 14 sheets at 1:25.000 scale that covers all this territory, was finished. Several techniques, such as terrain and vegetation analysis, inquiries to Pyrenean inhabitants, winter survey, historical documentation and dendrochronology, were used in this program. The data collected during the mapping process were stored in a digital database specially designed for that purpose. This database allows update, and efficient storage and management of the information. The present paper has the goal to analyze and discuss the acquired avalanche information. The results show the complementary of the different kinds of information. Using this data, a first spatial characterization of the avalanche terrain and the avalanches in this region was done.
