This week’s Photo Friday features a special treasure: the historic pictures of Alaska glaciers. The images were selected from the special collection of Alaskan glacier surveys led by William O. Field during International Geophysical Year (IGY), 1957-1958.
These photos include Alaska glaciers like Columbia Glacier, Worthington Glacier, Grand Pacific Glacier, Northland Glacier, Lawrence Glacier, Ripon Glacier, and Yale Glacier, which are only a small part of the enormous collection. These photos represent an attempt to systematically study glacier change in Alaska. The photos can be accessed via National Snow and Ice Data Center.
