Sperry Glacier Panoramic 1913 - 2008

The 1913 image of Sperry Glacier shows the thickness of the glacial ice that once covered the Sperry basin. Now, at approximately 1/3 of it's maximum area, Sperry Glacier continues to recede at a rapid rate. It is one of the glaciers that USGS scientists are monitoring as a benchmark glacier.
