Late Pleistocene Glaciations of the Snag-Klutlan Area
ABSTRACT. Two late Pleistocene limits of glaciation were delineated in the Snag-Klutlan area. Radiocarbon dates, surficial characteristics of its drift, and the palynol-ogy of overlying sediments imply the older glaciation (Mirror Creek) is early Wis-consin in age; the younger glaciation (Macauley)...

| Summary: | ABSTRACT. Two late Pleistocene limits of glaciation were delineated in the Snag-Klutlan area. Radiocarbon dates, surficial characteristics of its drift, and the palynol-ogy of overlying sediments imply the older glaciation (Mirror Creek) is early Wis-consin in age; the younger glaciation (Macauley) is late Wisconsin in age and culminated c. 13,700 B.P. The stratigraphy of depositswithin the Macauley glacial limit implies that deglaciation between the two glaciations was minimal. R ~ S U M É. Glaciations finî-pléistocènes dans la région de Snag-KIutlan, Territoire du Yukon. On a retracé dans la région de Snag-Klutlan deux limites fini-pléistodnes de glaciation. Les datations au radiocarbone, les caractéristiques superficielles de sa moraine et la palynologie des sédiments de recouvrement impliquent que la plus ancienne glaciation (Mirror Creek) est d’âge wisconsinien ancien; la glaciation plus récente (Macauley) est d’âge hi-wisconsinien et a culminé vers 13,700 A.P. La stratigraphie des dépôts englobés par la limite glaciaire de Macauley laisse supposer que la déglaciation interglaciaire a été minime.
