Glacial Flowlines of Alberta

This map depicts a generalized reconstruction of the direction and relative age of major ice flow trajectories within the Laurentide and Cordilleran ice sheets based on the morphometry, proximity, and parallel concordance of previously mapped glacial landforms. These enable a comprehensive large-scale reconstruction of evolving configuration and flow geometry of these ice sheets as they advanced and retreated across Alberta during, and potentially prior to the last glaciation.
