Description :
This paper describes a largely unrecognized source of panoramic photographs from the 1930s for fire lookouts in the American West, and uses a set of those photographs from Glacier National Park (GNP), to illustrate landscape changes through rephotography. The AA. rephotographed 360° panoramas from 9 of the same fire lookouts and qualitatively and quantitatively compared the nature and amount of landscape change from 1935 to the late 1990s. Geomorphic changes in general were less distinct than biogeographic changes.
