Book Description
The area studied in this paper covers southern Cortes Island, Marina Island, and north-west Hernando Island in the Strait of Georgia, British Columbia. The paper first reviews the geological setting & physiography of the study area, then presents results of mapping Pleistocene (Wisconsinan) strata exposed in the area. The stratigraphic succession, having maximum thickness of 130 metres, is subdivided into six major units, all recording cyclical, climate-controlled, primarily marine deposition. Established names are used for two widespread formations (Cowichan Head and Quadra Sand) and local names are introduced for newly determined formations. Probable sources of the formation sediments are briefly discussed.

Book Description
This report details the results of geochronological measurements made on 19 samples from locations in & directly adjacent to the eastern Bella Coola map area of British Columbia. The analytical data were extracted from a large, mostly unpublished data set that includes uranium/lead, potassium/argon, and argon/argon geochronometry for other parts of the Anahim Lake and Mount Waddington map areas. Analytical data, geological ages, and relevant observations for each dated sample are presented in chronological order. The age results provide broad constraints on pluton emplacement, volcanic eruption, and structural & metamorphic relationships in the study area, although these are discussed only in general terms.

Book Description
The mission of the U.S. Geological Survey (USGS) Water Resources Discipline is to provide the information and understanding needed for wise management of the Nation's water resources. Inherent in this mission is the responsibility of collecting data that accurately describe the physical, chemical, and biological attributes of water systems. These data are used for environmental and resource assessments by the USGS, other government agencies and scientific organizations, and the general public. Reliable and quality-assured data are essential to the credibility and impartiality of the water-resources appraisals carried out by the USGS.
