Abstract: NivoTest is dedicated to free riders (using skis, snowboards, snowmobiles, etc.) who feel concerned by avalanches. It is designed to help to assess avalanche risk for a given mountain route. It is a small card (3.3' x 5.9') with a revolving graduated disk. On the face of NivoTest, one can read some questions about weather, snow pack, past avalanches, topography and group competence. According to the answers, one has to turn the disk or not. The final position of the disk indicates the local avalanche risk level. Corresponding advise is written on verso. NivoTest is based on classic risk theory and scoring techniques. It was developed from results of research about local avalanche forecasting as well as field experiments recorded into NivoLog databases. The use of NivoTest is very easy and does not require any instrument. The skier only has to look around and observe snow and terrain to make a diagnosis, and then, his decision. Thus NivoTest is a pocket decision tool as well as a friendly teaching support.
