Data from: Historical retreat of alpine glaciers in the Ahklun Mountains, western Alaska
The Ahklun Mountains support the only extant glaciers in western Alaska. The glaciers were originally mapped by the U.S. Geological Survey using photogrammetry methods based on 1972 - 1973 aerial photos. We surveyed for presence or absence of the glaciers by fixed-wing aircraft in 2006. Of 109 glaci...
