Alberta During the Last Glacial Event (Late Wisconsin)

The ice flow of the Laurentide Ice Sheet during the last glacial event (Late Wisconsin) some 20,000 to 9,000 (radiocarbon) years ago. The large arrows indicate ice flow at glacial maximum. The smaller arrows indicate general flow directions during deglaciation (modified from Fenton et al. 2003).
