Dante's Peak | 1997
The fictional town of ‘Dante’s Peak’ is Wallace, in the Bitteroot Mountains, part of the Western Rockies in Idaho. 'Dante's Peak' itself, and the surrounding mountain scenery, were added digitally.
Wallace was also a location for Michael Cimino’s Heaven’s Gate.
The destroyed Dante's Peak community at the end of the film, with the camera shot moving out to show a wider scene of disaster and what remains of the crater, is actually an image of Mount St. Helens taken from news footage just after the May 18, 1980, eruption.
The USGS's ‘David A. Johnston Cascades Volcano Observatory Headquarters’, supposedly in Vancouver, Washington, is Point Dume Post Office, 29160 Heathercliff Road, Malibu, just off the Pacific Coast Highway.
