The Glacier RePhoto Project


The Glacier RePhoto Project seeks to summarize the existing glacier repeat photographic record throughout the American West. The objectives are to organize historical repeat photographs, their locations, and photographic attributes into a database and acquire new repeat photographs. Repeat photographs have been collected intermittently over the past century. However, the photographs are scattered in various photo collections, archives, and reports, which result in a fragmented view of glacier change. This database provides an organized solution by maintaining the photographs and associated metadata, including geographic coordinates, in a central location. There are currently 292 known stations in the American West with over 1400 photographs taken at those stations. 


The glacier repeat photography database stores photograph information by location, known as a repeat photograph station. The database contains two tables: one table for photo stations and a second table of photographs.  The number of photos taken from each station range between 2 and 33.  See the Documentation page for more information.

This project was created by Hassan Basagic, with funding from a Mazamas Research Grant and an American Alpine Club Nikwax Alpine Bellwether Grant in 2012. The project was a collaboration with Andrew Fountain and the Glaciers of the American West Project at Portland State University (//

A tool to view individual glacier repeat images and their locations in the western United States. The viewer features a map pane and a photo details pane. Use the map extent to filter the photo details pane. Bookmarks (upper right) and selection tools (upper left) assist in selecting regions or stations. Note that the repeat images displayed in this viewer are the raw, archive version and are likely not aligned in frame and scale. 


The following services are available upon request:


This project receives photographic contributions from a network of organizations and individuals. Please contact me if interested in contributing images to the database.


Below are selected glacier repeat photographs from the American West. If you are interested in using these images or would like to request prints, please contact Hassan Basagic.
