Check out this charming silent travel film of a 1920-something visit to Glacier National Park:
The film is part of the Burton Holmes Archive:
The Burton Holmes Archive is the world’s largest repository of films,
photographs, programs, scrapbooks, and other ephemera related to the
life and career of Burton Holmes, the “Father of the Travelogue”, and
that of his cameraman and associate, Andre de la Varre. If you’d like to see more of this collection, take a look at our Photostream, our Photo Sets, or watch a slideshow of the entire collection. In addition, you can watch films made by Holmes at: Burton Holmes Films, as well as those by de la Varre at Andre de la Varre Films.
The above film appears to be the only one from the Northwest, however there is also a film of a 1920s visit to the Grand Canyon (check out the clothes on the tourists!) and such exotic destinations as Bits of Life In Japan 1920s or Nine Glories of Paris - 1920s. The casual racism of some of the captions are striking to the modern eye (the Japanese entertainers are "charmingly childlike") but overall the films are striking and intimate glimpses into the world of 90 years ago.
