The Fort Fraser and Manson River map areas were last glaciated during the Late Wisconsinan Fraser Glaciation. Quaternary sediments predating this event are rare. The oldest deposits identified are oxidized sand and gravel, which locally contain placer gold. Stratigraphic evidence of a pre-Fraser glaciation was found at one site. Sediments of the Olympia Nonglacial Interval have been identified at three sites. Paleoecological reconstruction indicates climatic conditions cooler than at present for at least part of that nonglacial interval.--Abstract Résumés en français Softcover 00-46 2000-11-17 Sedimentology gcpds Geology gcpds Plouffe, Alain Bulletin, 0068-7626 554 (CaOODSP)9.514768
