USGS Historical Topographic Maps for the Juneau Icefield area

The Juneau Icefield is a geological icefield located just north and east of Juneau, Alaska and continues north to the Skagway, Alaska area. Current research of Climate Change in the field of Glaciology relies upon comparison of historical glacier mass-balance to current conditions. The United States Geological Survey (USGS) historical topographic maps, some more than 65 years old, are useful to a glaciologist in determining glacier change.
