Abstract

Thirty-two cosmogenic Cl 36 surface exposure ages constrain the timing of two late Pleistocene glacial advances in the western Ahklun Mountains. Boulders were sampled from one early Wisconsin (sensu lato) and six late Wisconsin moraines deposited by ice-cap outlet glaciers and local alpine glaciers. The Cl 36 ages are consistent with limiting C 14 and thermoluminescence ages from related deposits and indicate that Ahklun Mountains glaciers reached their most extensive position of the last glaciation early during the late Pleistocene, in contrast to the deep-sea isotopic record of global ice volume
