    Hiking

    The observatory tells the story of Mount St. Helens and the impact of its 1980 eruption - on the land as well as on animal and human life.

    Hiking

    The observatory was named after the volcanologist David A. Johnston, who died here on 18.05.1980. Here you can learn a lot about the disaster. You should definitely watch a movie.

    Hiking

    The volcano, whose north flank slipped in 1980, lost approximately 3 square kilometers of rock mass. The pyroclastic flows and the pressure wave were devastating.
