While difficult to quantify, this photo pair of Harrison Glacier exemplifies the loss of glacier volume. Comparison of the ice profile in the foreground of the photos shows a marked thinning of the glacier over the years,. Colorful layers of sedimentary bedrock are being exposed as the glacier recedes from the cliff bands.

Please respect the photographer: When using these photographs, please credit the photographer and source (eg. T.J. Hileman, courtesy of Glacier National Park Archives).
