Abstract
Three indicators - Athabasca sandstone, McMurray tar sand, and Presqu'ile dolomite - all demonstrate that the ice-movement direction in central and northern Alberta was southwesterly. Lines drawn from the present location of the indicators to various parts ofthe original outcrop area give siightly different directions of ice movement; this is especially true ofthe Athabasca sandstone which has the largest outcrop area of any of the source rocks.In general, however, the ice direction was about S. 20 -35 W.
