Ice-free conditions in southwestern British Columbia at 16000 years BP

This suggests that the Late Wisconsinan Cordilleran Ice Sheet reached its maximum extent in this region after...

Description
Summary:New radiocarbon dates on wood from two exposures in Chilliwack valley, southwestern British Columbia, indicate that this area was ice free and locally forested 16 000 radiocarbon years ago. This suggests that the Late Wisconsinan Cordilleran Ice Sheet reached its maximum extent in this region after 16 000 years BP. The Chilliwack valley dates are the youngest in British Columbia that bear on the growth of the Cordilleran Ice Sheet.
