Title

Geochemical Analysis of Stratigraphic Profiles to Reconstruct Unangax Past in the Islands of Four Mountains, Alaska

Presenter

Emily Deacon

Abstract

Thousands of years ago, ancient Unangax people first inhabited and built villages in the Aleutian Islands, where living conditions were very inhospitable. In the Islands of Four Mountains (IFM) region, the history of Unangax inhabitation was distorted after Russian colonization, which later led to abandonment of the IFM. However, these sites of Unangax habitation are still present within the IFM, and some of that lost history can be reconstructed and rediscovered through archaeology and geology. Geochemical analysis of stratigraphic profiles near these abandoned village sites targeted natural strata, such as volcanic ashes, as well as human-influenced layers. Being able to clearly identify he human-influenced by geochemistry and disturbed stratigraphy allows for extraction of human prehistory in the IFM without excavation of artifacts.
