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. Glaciations fini-pléistocènes dans la region de Snag-Klutlan, Territoire du Yukon. On a retracé dans la région de Snag-Klutlan deux limites fini-pléistocènes 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 fini-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.
