Volunteer Repeat Photography

Science Center Objects

Documenting the loss of ice among the glaciers of Glacier National Park has become an integral part of the USGS Climate Change in Mountain Ecosystems program.  Repeating historic photographs augments research and provides an effective means of visually communicating climate change.  The USGS encourages volunteer photographers to participate in capturing and submitting repeat photographs of glaciers to expand the USGS’ photo documentation of glaciers throughout the park. 

Get Involved in the USGS Repeat Photography Project!

Your photographs could help the USGS expand their collection of repeat photographs of glaciers in Glacier National Park.  Documenting the loss of ice and changing landscapes in Glacier National Park is a valuable component of the USGS Climate Change in Mountain Ecosystems program.  With a short window of time to photograph glacier margins, and limited staff to traverse the park in search of photos points, the involvement of volunteer photographers allows the USGS to expand collection of contemporary photographs that comprise the USGS Repeat Photography Project.  Participation involves printing historic photos from the list below, locating and photographing the repeat photo, and submitting photos and copyright agreement (see protocol for detailed instructions).  Volunteers must adhere to Glacier National Park's backcountry camping fees, regulations and advanced reservation policies.

Submission of your photographs to the USGS requires that you agree to the copyright release, thereby including the images in the public domain consistent with USGS policy. Accepted photographs will be archived as a visual record and they may also be used in USGS publications, presentations, websites and exhibitions of photo pairs. USGS will credit the photographer when the image is used.

While most of the images linked from this website are in the public domain, the images from the University of Montana are provided under the restriction that these high resolution versions be used solely for the scientific purpose of relocating the photograph, under the guidelines set forth in the protocol provided on this page. For information about other uses and permission, please visit the University of Montana Archive & Special Collections website. Photo numbers included in each photograph’s filename (eg 486.IX.067.070) may be used as identifiers when searching the U of M collections for these specific photos.

Thank you for your interest in helping the USGS compile a contemporary photographic record of the glaciers of Glacier National Park. We will be interested in seeing what your hikes among the mountains and glaciers reveal.
