Album 3: A JIRP Juneau Icefield Research Project, 1958; B Valdez Glacier, 1959. This album contains about 80 slides of the Battle Glacier branch of Gilkey Glacier, Juneau Icefield. These photos were taken in conjunction with research by other JIRP personnel. The 1953 JIRP field work was under Dr. Nielsen's leadership. The Valdez Glacier file covers an expedition to climb various mountains, and to seek relics of the ~ 1898 Gold Rush. At that time the glacier was used by ~ 3000 prospectors as a route to the Interior.
