Late Pleistocene Glaciations of the Snag-Klutlan Area, Yukon Territory

Abstract

Two late Pleistocene limits of glaciation were delineated in the Snag-Klutlan area. Radiocarbon dates, surficial characteristics of its drift, and the palynology of overlying sediments imply the older glaciation (Mirror Creek) is early Wisconsin in age; the younger glaciation (Macauley) is late Wisconsin in age and culminated c. 13 700 BP. The stratigraphy of deposits within the Macauley glacial limit implies that deglaciation between the two glaciations was minimal.
