Thesis (M.A.) University of Alaska Fairbanks, 2010"This thesis examines the geography and history of interior Alaska by tracing the route of Henry Allen's 1885 expedition and evaluating Alaska's physiography from both Clyde Wahrhaftig's and Allen's perspectives. Since the U.S. Army took a leading role in Alaska's era of exploration during the late nineteenth century, specific insights are drawn from Lieutenant Allen's expedition and its context within early Russian and American exploration to interpret the historical geography of Alaska. The purpose of this monograph., however, is more comprehensive than merely tracing Allen's expedition or Wahrhaftig's classification. This study's measure of success will be the extent to which the author's research illuminates the regional geography and history of America's 49th state, interprets Allen's geographic exploration within Wahrhaftig's physiographic framework, cultivates public interest with regard to the Allen expedition, and stimulates further research in fields related to Alaska's cultural landscape"--Leaf iii1.
