United States Geological Survey (USGS)


This project, conducted by the United States Geological Survey (USGS), documents changes over time in the landscape of Glacier National Park, particularly the retreat of the park's glaciers. The project involves pairing historic photos from the park's archives with recent photos to illustrate how the landscape has changed. Users can view and download the photos in pairs with dates and a caption describing the scene and the changes that have taken place.
