AbstractPart one of this two-part overview summarizes 1998 bedrock and surficial mapping of the joint Geological Survey of Canada, British Columbia Geological Survey Branch, universities, and industry project. Sixteen university students assisted 25 government and university researchers this field season. Bedrock geology was mapped in fourteen areas and surficial geology in six areas, all at a scale of 1: 50 000. Researchers studied biostratigraphy; sampled for isotopic-age dating; conducted detailed sedimentological and stratigraphic studies; measured magnetism, gravity and density; and sampled till, silt, lodgepole pine, and rocks in various geochemical studies. New geoscience contributions include 1) extending the delineation of the Sitlika Group sedimentary and volcanic rocks southward through the Fort Fraser map area, 2) redefining large tracts of western Cache Creek Group as Stikine and Sitlika assemblages, 3) recognition of Jura-Cretaceous contraction like the Skeena fold belt to the north, and 4) better definition of the distribution and tectonics of Miocene and Eocene volcanic and intrusive suites.
