How Have National Parks Changed Over Time?
Viewing photographs of different eras in the national parks can give many insights on ecosystem processes, as well as simply change over time. The photographs associated with panoramic lookout photographs provide a window on the past, and an opportunity to compare to the present with changes to land forms and land cover.
Osborne Photo Recording Transit
This gallery highlights photos of the Osborne Photo-Recording Transit, also called the Osborne camera and Osborne Photo Survey Camera.
The camera was used in both the 1930s for the original panoramic lookout photographs as well as for retakes in 2005-2009 in Yellowstone and Glacier national parks. Ten cameras were built by Leupold, Volpel & Co. According to We Climbed the Highest Mountains,#6 was built for the National Park Service. For the retake project in Yellowstone and Glacier national parks, #10 has been consistently used.
