Looking north from the west shoreline of Harris Bay, Kenai Fjords National Park, Kenai Mountains, Alaska. The rocky shoreline in the foreground is covered by small icebergs, calved by the retreating Northwestern Glacier. During the roughly 60 to 80 years between photographs, Northwestern Glacier retreated some 6 miles (10 kilometers) to the northwest, out of the field of view. U.S. Geological Survey, Department of the Interior. Earlier image is from a postcard, photographer unknown, courtesy of Kenai Fjords National Park. Later image is a USGS photograph by Bruce F. Molina.
