Learn more about the science of repeat photography and view photo pairs from parks including Klondike Gold Rush, Glacier Bay, Gates of the Artic, Kenai Fjords, and Denali.
Glacier National Park Repeat Photography Project
View and download high resolution photo pairs of glaciers from the USGS in Glacier National Park. These pairs show the effect of climate change on the park's glaciers.

This model was developed by the USGS Climate Change in Mountain Ecosystems Program in 2003. It shows changes in ice features and vegetation at Glacier National Park from 1850 to 2100. The model predicts that the park's glaciers will be gone by 2030. But the current rate of melting has surpassed the predicted rate, meaning that researchers believe the glaciers will be gone earlier than 2030.
