Building on previous ice-flow indicator compilations for British Columbia, this map and database illustrate major ice-flow directions for the Canadian sector of the Cordilleran ice sheet during the Late Pleistocene. The data were derived from published and unpublished surficial geology, terrain, and glacial feature maps. Because field data are sparse in the area ~ 300 km south of the British Columbia -Yukon border, new data were generated using digital stereo airphotos, digital derived-stereo orthophoto mosaics, and digital derived-stereo Satellite Pour l'Observation de la Terre (SPOT) imagery. The raw data are integrated into a single database; no attempt was made to reconcile cases where data from different sources conflict. The integrated database is published as BCGS Open File 2016-04 and the 152,000 ice-flow directional features are displayed on MapPlace.
