How Have National Parks Changed Over Time?
In the 1930s, panoramic photographs were taken from lookout points. Comparing these images to present-day photographs allows us to understand change 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 panoramic lookout photographs provide a window on the past and an opportunity to compare to the present with changes to landforms and land cover. Want to see more?
