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. The database and repeat photographs will be made available through this site.
There are currently 270 known stations in the American West with over 1300 photographs taken at those stations. The project has documented stations in the Sierra Nevada, Mount Shasta, Trinity Alps, Three Sisters, the Wallowas, Mount Hood, Mount Adams, Mount Rainier, Mount Baker, and the Front Range.
An interactive map displays the photo station location. Launch the map and select a station to view station information.

About the database
The glacier repeat photography database stores photographs and photograph information by location, known as a repeat photograph station. The number of photos taken from each station range between 2 and 33. Database tables are provided below.
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 is in collaboration with Andrew Fountain and the Glaciers of the American West Project at Portland State University (//glaciers.us).
