    “Glacial archaeology and human use of high altitudes in the Mongolian Altai”

    Dr. William Taylor -
    Curator of Archaeology, Assist. Professor of Anthropology, Univ. of Colorado Boulder

    From early human dispersals to the rise of Genghis Khan, Mongolia's high mountains have played a key role in some of humanity's most important social and environmental transitions. However, a coherent understanding of the region's past is hampered by the scarcity of the archaeological record, which has been worn thin through millennia of grazing and active geology. High altitude permanent snow and ice accumulations, known as ice patches, are a rare exception - preserving unique insights into the environmental and cultural history of Mongolia's alpine areas...
