Glaciers of Glacier National Park Repeat Photography Collection The “Glaciers of Glacier National Park Repeat Photography Collection” is a compilation of photographs documenting the retreat of glaciers in Glacier National Park, Montana, U.S.A. (GNP) through repeat photography. The collection is comprised of 57 image pairs, resulting from twenty-two years of U.S.Geological Survey (USGS) field excursions (1997-2019) for the purpose of photographically documenting glacier change. Historic images of glaciers were located at the USGS Photographic Library, GNP Archives, and the University of Montana Special Collections. Employees and volunteers of the USGS Repeat Photography Project relocated the site of each historic photograph and re-photographed the image to create a historic-contemporary...

This dataset does not include the 2005 extent of the named glaciers in GNP, which have been previously published. Of the perennial snow and ice features delineated here, 1.68 km2 (15.08%) of the total area exhibits characteristics indicative of active glacial ice. The imagery used to delineate perennial snow and ice was taken late season, therefore, all snow and ice present on the landscape is assumed to be perennial. Polygons were digitized based on National Agricultural Imagery Program (NAIP) imagery acquired in 2005, imagery acquired by the National Park Service in 2004...
