International Advanced Training Course on "Snow and Avalanches" 6 - 10 February 2023



The course aims at providing science and expertise based education with a mixture of lectures and hands-on activities. It is designed as an advanced level training intended for people with good basic knowledge and experience in the field of snow and avalanches. You will improve your observational skills in the field and your analytical capabilities in data interpretation and will be able to integrate new techniques and methods into your daily work. Furthermore, the international setting allows for a unique exchange of experience among practitioners with various backgrounds.

Target audience

Anyone working in the snow and avalanche business can participate. However, since it is an advanced course, good basic knowledge of snow and avalanche danger assessment and management is required. The course is intended for:

  • avalanche forecasters
  • avalanche specialists and consultants
  • avalanche instructors
  • avalanche hazard managers for infrastructures, avalanche control services
  • representatives of institutions, private services and associations
