Drift morphology, stratigraphy, and C-14 dates suggest chronology for Donjek and Kaskawulsh Glaciers. About 12,500 B.P. Kluane glaciers receded from near Kluane Lake and about 9780 B.P. withdrew behind present Kaskawulsh moraines. During Slims nonglacial interval, glaciers maintained retracted positions; Kaskawulsh terminus was located at least 13.7 miles up-glacier from its present position. Initial Neoglacial advance began before 2640 B.P.; continuous loess deposition suggests glaciers maintained positions more advanced than in Slims. The youngest advance occurring through the last few centuries is bracketed by seven C-14 dates; retreat beegan before A.D. 1865 and 1874. Comparison with events elsewhere supports initial widespread Neoglacial advance shortly before 2600-2800 B.P., and major events synchronous throughout the Northern Hemisphere.
