Abstract
Radiocarbon dates from crltical stratigraphic localities in southern British Columbia indicate that the growth history of the late Wisconsin Cordilleran Ice Sheet was different from that of most of the Laurentide Ice Sheet to the east. Much of southern British Columbia remained free of ice until after about 19,000 to 20,000 years ago; only adjacent to the Coast Mountains is there a record of lowland glacier tongues in the interval 22,000 to 20,000 yr BP. A major advance to the cllmax of late Wisconsin Cordilleran glacier ice in the northern States was not begun until after about 18,000 yr BP in the southwest of British Columbia and after about 17,500 yr BP in the southeast. The rate of glacier growth must have been very rapid in the two to three millennia prior to the climax, which has been dated in western Washington at shortly after 15,000 yr BP.
