NASA Landsat image from the U.S. Geological Survey's EROS Data Center. Will appear in USGS Prof. Paper 1386-J. Landsat 1 MSS image of Glacier Bay National Park and Preserve, southeastern Alaska, on 12 Sep 1973. In the 18th century, early sailing ships reported that Glacier Bay's glaciers extended to Cross Sound, the entrance on the Gulf of Alaska, so that a considerable retreat of glacier ice has occurred during the past two centuries. Light blue colors in the ocean and bay represent sediment from glacial streams. Landsat image 1416-19480 from the U.S. Geological Survey's EROS Data Center.
