Slope angles in the Alps provide critical information to ski tourers, freeriders or alpinists who are away from marked areas or designated trails and therefore have to assess the risk of avalanches.
They play a key role in the decision-making instruments that are common in Europe (e.g. 3x3, graphical reduction method). These methods take several factors into account when assessing avalanche danger:
- Avalanche Conditions (the level of danger according to avalanche warning services, weather, frequency of avalanches)
- Terrain (slope, exposure, danger spots)
- Human factors (group size, safety precautions)
These parameters should be used both in the initial planning phase and in a further assessment at the concerned area itself, to determine whether the level of risk posed for skiing and climbing in that area is acceptable.
The aim of our slope angle layer, which is divided into multiples of 5°, is to provide a more accurate picture of the terrain, this should be factored into your planning and risk assessments.
