Abstract
A deep-sea core in the eastern North Pacific Ocean indicates that the western margin of the Late Wisconsin Cordilleran Ice Sheet began to retreat from its maximum position after 15 600 yr BP. Ice-rafted detritus is present below the 15 600 yr BP level and was deposited while lobes of the Cordilleran Ice Sheet advanced across the continental shelf in Queen Charlotte Sound, Hecate Strait, and Dixon Entrance. Radiocarbon ages of late-glacial and postglacial sediments from Queen Charlotte Sound, Hecate Strait, and adjacent land areas show that deglaciation began in these areas before 15 000 yr BP and that the shelf was free of ice by 13 000 yr BP.
