Western Cordillera and Adjacent Areas
This volume includes guides for 15 of the field trips held in conjunction with the 2003 GSA Annual Meeting in Seattle. Topics covered include Glacial Lake Missoula and the Clark Fork Ice Dam; the Sauk Sequence in western Utah; the geology of wine in Washington state; the Columbia River basalt and Yakima Fold Belt; Alpine glaciation of the North Cascades; and recent geoarchaeological discoveries in central Washington. Quaternary geology of Seattle, engineering geology in the central Columbia Valley, and the tephrostratigraphy and paleogeography of southern Puget Sound also are covered, as are trips to central Cascade Range and the White River.
Recent geoarchaeological discoveries in central Washington
Published:January 01, 2003
Geoarchaeological research in the mid-Columbia region of central Washington over the past 10 yr has produced new information regarding Paleo-Indian archaeology and environmental change in the inland Northwest. Stratigraphic, sedimentological, and geomorphic studies provide important contextual information for locating and interpreting Washington’s earliest archaeological sites and human remains. Recent discoveries increasingly point toward human occupation of the region during a time of post-glacial warming and reduced effective moisture 11,200–9000 14C yr B.P. This field guide presents recent research focusing on geoarchaeological studies at the Kennewick Man discovery site, at latest Pleistocene relict Channeled Scabland marsh sites, and at...
