This study consisted in a precise mapping project (GPS field campaign, on-screen digitization of the topographic maps at 1:5.000 scale and updated with ASTER mission) of the Ceahlau mountain area in Romanian Carpathians in order to address the snow avalanche risk management, surveying and monitoring. Thus we considered the slope, aspect, altitude, landforms and roughness resulted from a high resolute numerical terrain model (31 square km at 1: 5.000 scale resulted in a spatial resolution of 3 m by the help of Topo to Raster tool). These parameters were calibrated after a model applied into Tatra Mountains and used over Ceahlau Massive. The results were adapted and interpreted considering to the European Avalanche Hazard Scale. This work was made in the context of the elaboration of Risk Map and is directly concerning both in the security of tourism activities but also in the management of Natural Park Ceahlau. The extension of this method to similar mountain areas is ongoing and finally the work has also an educational purpose.
